Comparison of 10 Best Air Conditioner “Portable” Units
For several years, consumers find disappointment over long-term usage of air conditioning products because of primarily relying on a single factor: upfront costs.
Following which, high energy consumption and usage safety has become a concern which prompted Federal officials to conduct a crackdown mode on the air conditioning industry, targeting manufacturers who falsely claimed their products are safe for long-term use, environmentally safe, and energy efficient.
About 60 percent of product owners interviewed, admitted that they were not aware of environmentally harmful elements produced by the brands they were buying — including the very constituents that can be responsible for developing health risks.
The issue raises many compliance questions for the air conditioning industry, the most important being the responsibility of manufacturers to ensure product safety.
So, we went deep behind the label to figure out which units make an excellent portable air conditioning product, which ones should be considered the best buys. For the project, we researched the leading products currently in the market.
At the end of the work, we settled on 10 products. Yes, just 10 of them!
We based our research on the following criteria:
• Strength & Reliability of Cooling Capacity
• Product Safety
• Customer Feedback
• Overall Value
It’s certain that you would like to make the best informed decision in selecting the right unit for yourself. If so, you should significantly look into the pros and cons of each product. But believe me, there is no product available that is 100% perfect. The good news is, there are some that can get pretty close to achieving a satisfactory result in portable air conditioning.
Now, we have here a technical specification comparison of the 10 best portable air conditioners. It comes along with an Amazon rating and price:

Top 10: Portable Air Conditioner Reviews
Here goes a brief review on the top 10 portable air conditioner units:
To start, what I like the best about the American Comfort product is the way it’s been designed with the most advanced features in portable air conditioning. In addition to providing you a comfortable and cool place with its 13000 BTU power, especially when the temperature becomes unbearable, it also boasts a functionality of working as a dehumidifier.
Aside from that, the following are some advantages that makes this unit one of the best:
- This item is multifaceted where it can operate as a cooling unit, dehumidifier, and air purifier. The dual purpose model includes a heater.
- The air purification system is built with a washable filter that also comes with an activated carbon filter to help reduce unpleasant room odor. Good for people with asthma or allergies to avoid airborne contaminants. (1)
- Its dehumidifier function helps eliminate about 66 pints of moisture each day which can cause growth of molds and fungus.
- Compact in its built and features integral handles and caster wheels, making portability convenient.
- It’s also nice to know that it’s been engineered with programmable timers and electronic display, which means that you can make adjustments and directly control the airflow conveniently. (2)
- Prides an AutoDrain technology so you don’t have to manually perform any draining.
- Its ABS plastic window venting kit is a perfect solution if you’ve got no appropriate window size.
- Energy efficient
On the other hand, what I least like about this unit is it can only cover spaces or rooms with less than 350 sq. ft. Moreover, it generates a humming sound but not as bad as other portable air conditioner units. But according to those with good noise tolerance level, unlike me, barely hear a sound.
If you’re looking for a portable air conditioner to be used in a larger room, the Amico AP11000 is built with the capacity to cool and dehumidify a room with an area of up to 400 sq. ft. But of course, results can be affected by how much heat is being circulated in the room – probably due to direct sunlight entering the room. This unit has a power of 11,000 BTUs. For even at a lower price tag, it can rival the expensive portable air conditioners.
Here are the good points that make Amico another top portable air conditioner:
- It is one with the lowest noise ratings at only 48 dBA.
- The unit comes with castors so users can roll it easily from room to room.
- It is lighter than most portable air conditioners. It only weighs 55 pounds.
- It has a programmable timer and temperature control that can be adjusted via its console or with a remote.
- Its dehumidifier setting can clear out 61 pints of moisture from the air each day.
- It has an auto-evaporative function to vent the moisture outside.
Although, there may be some minor drawbacks about this unit, it is still holds its position as one of the best. For example, its window kit is only made of foams, so you have to purchase a second one. It also doesn’t list its energy efficiency rating and lacks the sleep mode option which is important when the unit is not in use. Moreover, in humid conditions, you have to drain the unit manually.
The Frigidaire FRA053PU1 is a relatively powerful portable air conditioner especially when you consider it’s price point. It is for this one reason among others that it is included on our list.
While it is truly the least powerful portable AC on the list, we decided to include it for those limited with a tighter budget. If you only have a few hundred dollars to spend on a portable AC, and don’t foresee yourself upgrading within a couple of years, then this is a great choice.
This can also be the preferred choice for parents looking to buy their children a decent quality portable air conditioner to help feed a growing comfort. The setup of the unit is super simple and requires no complicated tools.
In fact, within minutes of unpackaging, you can enjoy a power of 5000 BTU to cool down up to 216 square feet room. The quality of components used are nothing short of what you would expect from any Frigidaire product.
The warranty included will keep you feel comfortable that it remains covered for many months to come, and as not with any product, it brings a full 1 year warranty on parts and labor, along with a limited 2-5 year warranty-sealed system.
A window kit is also included in the package and contains means of adjustable options for a perfect window fit. Overall, this is the prime choice for those looking for a serious and reliable unit for as cheap as possible.
While the Haier HPN14XCM might ring up at the uppermost price range of what most beginners are wanting to spend, it truly is (in our opinion) one of the perfect and most reliable portable air conditioner for new users.
The reason? Well for starters, in addition to it’s modern design, the Haier HPN14XCM has numerous certifications to put the new user at ease.
It can work as an air conditioner and dehumidifier eliminating 3.3 pints of water an hour, making the initially daunting task of dealing with humidity infinitely easier. (3)
Many beginners get disheartened, and undeniably even give up, after spending money on really cheap air conditioners trying to make a saving but ended up costing a lot more in the long run.
Starting out with a top proven product completely eliminates that frustration and enables beginners to be able to enjoy a truly comfortable night and day, immediately.
The Haier HPN14XCM is the perfect balance of quality and price point. The best portable air conditioners are arguably the epitome of quality comfort, and this is a mid-range portable AC in the Haier line.
Serious beginners will find it easier to have more enjoyment (and by extension motivation in regards to right comfort) with the Haier HPN14XCM than they would with most other products.
Sometimes great things come in small packages. The 49.6lbs Honeywell MN10CESWW is a prime example.
While being, by far, the smallest and one of the most inexpensive units on the list, it has the most positive reviews and totally makes up for in convenience and mobility.
Many users can conveniently transfer the unit from room to room where it may be needed, or far outside of the house to another place. For such individuals, packing around a larger unit, as a comparison, just isn’t totally feasible.
The Honeywell MN10CESWW was made with these people in mind. It comes with both a light body and rotatable castor wheels which make it easy to drive out to a new location, set up to a room, and begin experiencing a cooling comfort all in a matter of minutes. (4)
It is also a great buy for families who have younger kids who may express interest in an ecofriendly environment, but are unsure whether this interest will be helpful in the long run for their kids. (5)
In such cases, parents may not want to invest the amount of money that high quality units demand. But, such parents will also be well pleased with chemical free Honeywell.
While many characteristics of this unit are to be appreciated, it admittedly has a significantly smaller aperture than the rest of the pack. This means that it is also significantly a bit less powerful and covers only up to 400 square feet – although it is still many times more powerful than other units!
Concerned parties should also bear in mind that even though it is intended to be portable, it is still a delicate appliance and owners should be gentle in packing it around. If you aren’t looking for anything particularly powerful and plan on observing in many different areas, then you’ll be hard pressed to find another portable air conditioner of this quality built for easy transfer.
While not quite as wide as the Haier HPN10XCM and Soleus Air LX-140 unit, the Koldfront portable air conditioner is actually a bit bulky as well, weighing about 75 pounds.
It is also noticeably tall due to it’s high power capacity. Like it’s relatives on the list, the Koldfront PAC1401W is solidly built. You can say at first look that several of the cheaper products on the market have weak bases and are made with “cost saving” materials.
On your first encounter with the Koldfront PAC1401W, you’ll know that it’s anything but cheaply built. This is a portable air conditioner that will last for years.
It’s wheeled mount allows you to easily transport it around the house or any other flat surface. Be aware that when using the unit, it may produce a small negative air pressure being a single hose unit. (6)
It also includes 24/7 programmable system to help beginners schedule use. The PAC1401W is actually one of the most popular among all portable air conditioners that Koldfront offers. It is marketed for it’s portability, and is a great solution if you often need its usage from one place to another, and want something much more powerful than the Honeywell MN10CESWW unit.
It has 14,000 BTUs that can cover an area of 500 sq. ft. This is a great product, well priced for those who want an amazing experience, but aren’t yet ready to pay a higher price to join users with top of the line high-priced equipment.
The LG LP1414GXR isn’t multi-colored with cute pictures painted on the box, but why do we feel it’s perfect for a child?
First of all, understand that this unit is an actual real portable air conditioner, not just some kid’s toy. It’s best for children in a big room for they are quite better at handling noise and remain comfortable, not like adults. The unit has a noise level of 58dBA. (7)
LG LP1414GXR is well priced, and available for not much more than many units that are much less powerful that are marketed directly to families. The price of course is an important factor in making it a feasible choice for anyone looking for a great present for a family’s comfort.
However, the quality of the cooling that the unit delivers (which is many times better than most cheap products) ensures a rewarding experience for your children, which can help a child foster and experience a wonderful and fulfilling comfort.
Unlike many other products to consider, the LG LP1414GXR portable AC unit will not break after a few uses, and will certainly last for many years to come. This is the perfect product for parents wanting to buy a great portable air conditioner for the family to use in order to achieve enough and healthy sleeps, instead of unreliable equipment which might only be used a few times at best.
With over double the BTU power size of the Frigidaire unit, this portable air conditioner is one of the priciest on our list, but it’s also has highest area coverage of about 525 square feet. But a bit lower in price among other 14000 BTU units.
The quality of cooling comfort the unit produces is on par with the levels required by most new users seeking for top results. Although it does come with a higher price tag, it is money well spent as you definitely get the most out of each dollar.
The Soleus Air LX-140 is suitable for all levels of users. While many budding cooling comfort seekers buy a low range unit in the beginning, those who stick with it often feel the need to purchase a better one within a year as they advance in their needs.
However, it is not an issue to worry about with this choice. The Soleus Air LX-140 will satisfy the clarity cravings on both cooling and dehumidification needs. An additional attribute is an Energy Efficiency Rating of 10.1 that could help you put a cap on electricity bills. (8)
Like with the other portable air conditioners on our list, the Soleus Air LX-140 supports a window kit so to get a perfect fit for the exhaust. This is great for newcomers to the field, but won’t be necessary for those with a little more experience.
The whole piece weight about 96 lbs, which is a bit more bulky than the other units. This can make it a little more difficult to transfer if you plan to use it in different locations. However, this is expected in most portable products.
The higher BTU power the unit has, the bigger and less convenient it will be to transport. Either way the Soleus Air LX-140 is most likely the best choice for those who know that their desire for outstanding comfort will not quickly fade.
If you want a portable air conditioner that you certainly won’t feel compelled to replace within a few years, the Soleus Air LX-140 is strongly recommended for you.
The Sunpentown WA-1070E product has some good properties too that made me include it in this list of the best portable air conditioners. What I like most about the product is the fact that it is one of the few to have the lightest weight among the ten (10) products on the list, with only 53 pounds.
It makes it look a little smaller than the others. Being one to be of the smallest in size, it is also the lowest in price.
The following are some of its properties that are also worth noting:
- It is a very robust product with a fire resistant PVC plastic housing.
- It is purchase-ready with a very high quality built-in tank and extendable exhaust host of up to 59 inches.
So, if you are looking for a good investment, then this would probably one of your best options. However, it has some disadvantages too. For example, a number of users are having a difficult time installing the host to get the exhaust to work well.
Aside from that, the following aspects are some of the things that its manufacturer need to improve about the product:
- It has a high noise level of about 53 decibels. This is not advisable for people who have very low noise tolerance. However, this is a personal preference for some users don’t find it relevant at all.
This is a great choice for any buyer. Crafted by well-known manufacturer Whynter, it is a really solid portable air conditioner.
The Whynter ARC-14SH comes with a powerful BTU of 14,000 to cover an area of 500 sq. feet. It is ecofriendly and integrated with an energy efficient technology along with antimicrobial washable filter that purifies air. (9)
It also comes with 4 multi-directional casters which is great for easier portability of use around the house.
The unit is also perfect for use in cooling a room fast with its dual exhaust host. That said, there’s no negative pressure.
While this product comes strongly recommended for users, some may be put off by some of the limitations that comes with purchasing the product and that is its noise level of up to 56 dBa.
With it, the coolness and fresh air that can be received from the unit is many times more satisfying in achieving a great experience than with many products.
To sum it up, this sleek designed 100% CFC free product is a great home portable air conditioner for the entire family.

WHICH BEST PORTABLE AIR CONDITIONER IS THE BEST ONE?
The question on everyone’s mind looking for a portable air conditioner is which one they should choose.
There are various factors that you need to consider before you make your choice, as the model that will be best suited to your needs will be determined by things such as the room of use, preferred features, and other factors.
Some of the reasons people need air conditioning is previous experience with hot temperature health concerns like heat cramps, dizziness, fatigue, stress, etc.
While some people do look at price beyond everything else, you need to remember that cheapest is not always the best.
If you focus on price alone, you may end up with an inferior product that makes big claims but does little to help with air cooling or even produce harmful elements.
This is why it is important that you go for quality and value rather than trying to find the cheapest product regardless of quality or reviews.
You can then benefit from the confidence that, you have a portable air conditioner product that will actually perform well.
HEAT STRESS RELATING TO LACK OF PROPER AIR CONDITIONING
“Heat stress” is the “net [overall] heat load to which a worker may be exposed from the combined contributions of metabolic heat, environmental factors (i.e., air temperature, humidity, air movement, and radiant heat), and clothing requirements.” Metabolic heat is the heat produced by the body through chemical processes, exercise, hormone activity, digestion, etc. [Reference: 2016 TLVs and BEIs: Threshold Limit Values for Chemical Substances and Physical Agents and Biological Exposure Indices. Cincinnati, Ohio: American Conference of Governmental Industrial Hygienists, 2016. p.214.]
In laundries, restaurant kitchens, and canneries, high humidity adds to the heat burden.
In all instances, the cause of heat stress is a working environment which can potentially overwhelm the body’s ability to deal with heat.
Most people feel comfortable when the air temperature is between 20°C and 27°C and when the relative humidity ranges from 35 to 60%. When air temperature or humidity is higher, people feel uncomfortable. Such situations do not cause harm as long as the body can adjust and cope with the additional heat. Very hot environments can overwhelm the body’s coping mechanisms leading to a variety of serious and possibly fatal conditions.
HOW DOES THE HUMAN BODY REACT TO HOT ENVIRONMENTS?
The healthy human body maintains its internal temperature around 37°C. Variations, usually of less than 1°C, occur with the time of the day, level of physical activity or emotional state. A change of body temperature of more than 1°C occurs only during illness or when environmental conditions are more than the body’s ability to cope with extreme heat.
As the environment warms-up, the body tends to warm-up as well. The body’s internal “thermostat” maintains a constant inner body temperature by pumping more blood to the skin and by increasing sweat production. In this way, the body increases the rate of heat loss to balance the heat burden. In a very hot environment, the rate of “heat gain” is more than the rate of “heat loss” and the body temperature begins to rise. A rise in the body temperature results in heat illnesses.
HOW DOES THE BODY CONTROL HEAT GAIN AND HEAT LOSS?
The main source of heat in normal conditions is the body’s own internal heat. Called metabolic heat, it is generated within the body by the biochemical processes that keep us alive and by the energy we use in physical activity. The body exchanges heat with its surroundings mainly through radiation, convection, and evaporation of sweat.
Radiation is the process by which the body gains heat from surrounding hot objects, such as hot metal, furnaces or steam pipes, and loses heat to cold objects, such as chilled metallic surfaces, without contact with them. No radiant heat gain or loss occurs when the temperature of surrounding objects is the same as the skin temperature (about 35°C).
Convection is the process by which the body exchanges heat with the surrounding air. The body gains heat from hot air and loses heat to cold air which comes in contact with the skin. Convective heat exchange increases with increasing air speed and increased differences between air and skin temperature.
Evaporation of sweat from the skin cools the body. Evaporation occurs more quickly and the cooling effect is more noticeable with high wind speeds and low relative humidity. In hot and humid workplaces, the cooling of the body due to sweat evaporation is limited because the air cannot accept more moisture. In hot and dry workplaces, the cooling due to sweat evaporation is limited by the amount of sweat produced by the body.
The body also exchanges small amounts of heat by conduction and breathing. By conduction, the body gains or loses heat when it comes into direct contact with hot or cold objects. Breathing exchanges heat because the respiratory system warms the inhaled air. When exhaled, this warmed air carries away some of the body’s heat. However, the amount of heat exchanged through conduction and breathing is normally small enough to be ignored in assessing the heat load on the body.
WHAT ARE THE EFFECTS OF HEAT ON THE BODY?
When the air temperature or humidity rises above the range for comfort, problems can arise. The first effects relate to how you feel. Exposure to more heat can cause health problems and may affect performance.
As the temperature or heat burden increases, people may feel:
- Increased irritability.
- Loss of concentration and ability to do mental tasks.
- Loss of ability to do skilled tasks or heavy work.
In moderately hot environments, the body “goes to work” to get rid of excess heat so it can maintain its normal body temperature. The heart rate increases to pump more blood through outer body parts and skin so that excess heat is lost to the environment, and sweating occurs. These changes place additional demands on the body. Changes in blood flow and excessive sweating reduce a person’s ability to do physical and mental work. Manual work creates additional metabolic heat and adds to the body heat burden. When the environmental temperature rises above 30°C, it may interfere with the performance of mental tasks.
DOES EVERYONE REACT TO HEAT THE SAME WAY?
The risk of heat-related illness varies from person to person. A person’s general health influences how well the person adapts to heat (and cold).
Those with extra weight often have trouble in hot situations as the body has difficulty maintaining a good heat balance. Age (particularly for people about 45 years and older), poor general health, and a low level of fitness will make people more susceptible to feeling the extremes of heat.
Medical conditions can also increase how susceptible the body is. People with heart disease, high blood pressure, respiratory disease and uncontrolled diabetes may need to take special precautions. In addition, people with skin diseases and rashes may be more susceptible to heat. Other factors include circulatory system capacity, sweat production and the ability to regulate electrolyte balance.
Substances — both prescription or otherwise — can also have an impact on how people react to heat.
The National Institute for Occupational Safety and Health (NIOSH) reports that several studies comparing the heat tolerances of men and women have concluded that women are less heat tolerant than men. While this difference seems to diminish when such comparisons take into account cardiovascular fitness, body size, and acclimatization, women tend to have a lower sweat rate than men of equal fitness, size and acclimatization. This lower sweat rate means that there can be an increase in body temperature.
WHAT ARE THE ILLNESSES CAUSED BY HEAT EXPOSURE?
Heat exposure causes the following illnesses:
Heat edema is swelling which generally occurs among people who are not acclimatized to working in hot conditions. Swelling is often most noticeable in the ankles. Recovery occurs after a day or two in a cool environment.
Heat rashes are tiny red spots on the skin which cause a prickling sensation during heat exposure. The spots are the result of inflammation caused when the ducts of sweat glands become plugged.
Heat cramps are sharp pains in the muscles that may occur alone or be combined with one of the other heat stress disorders. The cause is salt imbalance resulting from the failure to replace salt lost with sweat. Cramps most often occur when people drink large amounts of water without sufficient salt (electrolyte) replacement.
Heat exhaustion is caused by loss of body water and salt through excessive sweating. Signs and symptoms of heat exhaustion include: heavy sweating, weakness, dizziness, visual disturbances, intense thirst, nausea, headache, vomiting, diarrhea, muscle cramps, breathlessness, palpitations, tingling and numbness of the hands and feet. Recovery occurs after resting in a cool area and consuming cool drinks (e.g., water, clear juice, or a sports drink).
Heat syncope is heat-induced dizziness and fainting induced by temporarily insufficient flow of blood to the brain while a person is standing. It occurs mostly among unacclimatized people. It is caused by the loss of body fluids through sweating, and by lowered blood pressure due to pooling of blood in the legs. Recovery is rapid after rest in a cool area.
Heat stroke is the most serious type of heat illness. Signs of heat stroke include body temperature often greater than 41°C, and complete or partial loss of consciousness. Sweating is not a good sign of heat stress as there are two types of heat stroke – “classical” where there is little or no sweating (usually occurs in children, persons who are chronically ill, and the elderly), and “exertional” where body temperature rises because of strenuous exercise or work and sweating is usually present.
Heat stroke requires immediate first aid and medical attention. Delayed treatment may result in death.
WHAT ARE SYMPTOMS AND FIRST AID STEPS FOR HEAT EXHAUSTION?
Symptoms of heat exhaustion may start suddenly, and include:
- Nausea or irritability.
- Muscle cramps or weakness.
- Feeling faint.
- Heavy sweating.
- High body temperature.
First aid for heat exhaustion includes:
- Get medical aid. Stay with the person until help arrives.
- Move to a cooler, shaded location.
- Remove as many clothes as possible (including socks and shoes).
- Apply cool, wet cloth or ice to head, face or neck. Spray with cool water.
- Encourage the person to drink water, clear juice, or a sports drink.
WHAT ARE THE SYMPTOMS AND FIRST AID STEPS FOR HEAT STROKE?
Heat exhaustion may quickly develop into heat stroke. Symptoms of heat stroke include:
- Hot, dry skin or profuse sweating.
- Loss of consciousness.
- Very high body temperature.
First aid for heat stroke includes:
- Call 911 immediately. Heat stroke is a medical emergency.
- Stay with the person until help arrives.
- Move to a cooler, shaded location.
- Remove as many clothes as possible (including socks and shoes).
- Wet the person’s skin and clothing with cool water.
- Apply cold, wet clothes or ice to head, face, neck, armpits, and groin.
- Do not try to force the person to drink liquids.
WHAT ARE THE ILLNESSES CAUSED BY LONG-TERM (CHRONIC) HEAT EXPOSURE?
NIOSH reports that certain heart, kidney, and liver damage are thought by some researchers to be linked to long-term heat exposure. However, the evidence supporting these associations is not conclusive.
Chronic heat exhaustion, sleep disturbances and susceptibility to minor injuries and sicknesses have all been attributed to the possible effects of prolonged exposure to heat.
Heat exposure has been associated with temporary infertility in both women and men, with the effects being more pronounced in men. Sperm density, motility, and the percentage of normally shaped sperm can decrease significantly when the temperature of the groin is increased above a normal temperature. Workers exposed to high heat loads should inform their family doctors of their exposure.
Laboratory study of animals has shown that exposure of the pregnant females to high temperatures may result in a high incidence of embryo deaths and malformations of the head and the central nervous system (CNS). There is no conclusive evidence of teratogenic effects of high temperatures in humans. The NIOSH criteria document (Draft: 2013) recommends that a pregnant worker’s body temperature should not exceed 39-39.5°C during the first trimester of pregnancy.

So what is the best portable air conditioner out there? I find all these 10 products from 10 different brands to be among a few of the best portable air conditioners. There are actually a lot of other units available but these are but the units that meets my requirements. My personal favorite is LG LP1213GXR but its high cost doesn’t practically make it to be my best choice.
If I’ve only got 1 vote, I would gladly give it to Whynter ARC-14SH for it has proven itself to be the product that fits most of the criteria placed. And it’s much more affordable, considering that it also has a very good set of advantages (i just love its sleek modern design!) and only a few minor disadvantages. Moreover, I can see that 234 people recommends it at this point, and I can’t just simply ignore the fact that it’s actually worth it. Key factors + several satisfied customers have convinced me that this certainly is the best portable air conditioner!
The other 9 products presented are certainly of great value as well. You’ll surely get what you paid for, but of course, Whynter ARC-14SH should be one of your best options!
