To make sure that the air you breathe is thoroughly cleaned and fresh, this Whynter model is also equipped with 2 types of filters – washable pre-filter and activated carbon filter. While the pre-filter traps airborne particles, the activated carbon filter, which often referred to as charcoal-activated cabin filter, helps to remove any unpleasant smell and other gaseous compounds that can be harmful to one’s body.

So if you are looking for a portable air conditioner that can cool off a smaller space well, then this unit is recommended for rooms up to 300 square feet.

The SPT WA-8070E also comes with a self-drain system that will automatically drain the water it produced during the cooling process so that you won’t need to drain the water tank now and then.

If you have the large master bedroom, this Global Air portable air conditioner can handle it – the 10,000 BTU unit can cool down spaces up to 400 square feet. This unit is a very basic portable air conditioner – meaning it doesn’t have all the bells and whistles of some of the more advanced units but it still does a good job on cooling the room. That said, if you are into plug-and-play technology or are on a tight budget, this small portable AC may be for you.

The Global Air portable air conditioner offers two-speed cooling and fan, unlike most of the other units that offer three speeds. The airflow can be adjusted in 4 directions to gives evenly spread air throughout the room, so your entire room will get an even cool in a matter of 30 minutes. The wind from the unit blows upward and also has an anti-frozen feature under cooling. When it comes to noise level, light sleepers will enjoy how quietly this Global Air unit operates.

With a weight of 54 pounds, this Global model is one of the most lightweight units in its class. Additionally, the unit comes with smooth-gliding casters which makes it extremely easy to move from room to room. When fully assembled, the units measure 17 inches by 13 inches by 31.3 inches, making it compact and an accommodating addition to any space.

Like most portable units, the Global Air unit incorporates a few convenient features. First, the control panel is located on the top of the unit and has a very straightforward LED readout. It has a remote control, handy for controlling the air conditioner from across the room. It also comes with an over cold protection and optional active carbon filters. You will also appreciate the inclusion of the restart delay function that the unit will restart automatically in case of power shut off, delay function is of 3 minutes.

The main issue with this Global Air model is that its self-evaporative system does not work as well as advertised and the water tank will need to be emptied about every 12 hours. In highly-humid weather, this can be pretty often! So if the self-evaporative system is important in your choice of the portable air conditioner, you should consider other options such as the LG LP0817WSR model.

The unit does come with a one-year warranty – just in case there are any problems. Overall, the Global Air portable air conditioner is a very simple design that does most things fairly well. It does not cool as much as large space, or as efficiently as other powerful models. But for people who are looking for an affordable option or simply need a basic cooler, then this unit will get your space cool reasonably well and cost-effectively.

  • Simple to use
  • Lightweight and portable
  • Relatively quiet
  • Restart delay function

Honeywell MN10CESBB Portable Air Conditioner

Honeywell is a well-recognized name in the home air conditioning industry. The manufacturer has been around a long time, 133 years to be exact – longer even than Black & Decker. Thus, it is no surprise that they have been able to create innovative, efficient, and quiet machines.

Honeywell MN10CESBB Portable Air Conditioner is a great example of the type of cuttings edge and reliable products that the manufacturer produces. It has 10,000 BTU of cooling capacity, which is sufficient for effective cooling of rooms up to 450 square feet. That makes it ideal for use in various places such as living rooms, computer labs, or server rooms.

This attractive black unit features a dehumidifier that is capable of removing moisture in your room at an impressive official rate of 80.1 pints per day. The unit also features a fan-only function. Its fan has an airflow rate of 174 cubic feet per minute which effectively circulates the air in a room. The unit can circulate air at low, medium and high speeds to provide cooling against different levels of heat.

The Honeywell MN10CESBB comes with a 3.9 feet extendable exhaust hose. Since its hose is short, you will need to place this model close to the window so it can release excess air and moisture. This unit also comes with a window venting kit that fits standard windows from 19.7 to 47.25 inches wide. The window vent is non-permanent that allows you to remove it every time the unit is not in use.

This MN10CESBB model weighs 63.9 pounds, which is not the lightest air conditioner on the market. However, if you plan on moving this unit around the home, you will be delighted at how easily the included casters roll.

The air conditioning unit has an auto-evaporation system that removes condensed water, so you won’t have to drain the unit unless you live in a very humid area. Besides, the machine has a washable pre-filter which cleans the air from large floating particles such as dust, pet hair, etc.

Although the MN10CESBB is quite powerful, it is very quiet. In fact, it is one of the quietest 10,000 BTU units that I have come across, operating at only 51 decibels. The low noise level ensures that the unit won’t disturb you even at night and you do not need to turn up the TV volume while staying cool.

The MN10CESBB model includes a full-function remote control which is rather straightforward: a power button, speed buttons, a timer setting, arrow controls, and mode change. It also includes an easy-to-understand LED control panel.

The main downside to this unit is the lack of some convenience features such as an auto-restart function or a sleep mode. This means you will need to reset the machine after a power outage. And because the machine does not have the sleep mode, it cannot adjust the temperature to a comfortable level while you sleep. You can find these missing features on the LG LP0817WSR air conditioner and other models we assessed to be the best small portable AC units.

This model is listed in our reviews because of its compact design, effective cooling, and durability. Moreover, it is of good quality materials and comes with a five-year warranty on the compressor and a one-year warranty on the unit. Unfortunately for a manufacturer that pride itself on energy efficient machine, the MN10CESBB has a fairly low Energy Efficiency Ratio – which is EER 9.5. However, this appliance is still a great option for those who are looking for a small, quiet and efficient machine.


  • Sleek design
  • One of the quietest models on the market
  • User-friendly control panel and remote control
  • Easy to move and clean


  • EER is slightly below average
  • Lacks some convenient functions

Haier HPN12XCM Portable Air Conditioner

Moving on to the 12,000 BTU air conditioner, we have the HPN12XCM from Haier – one of the great AC brands in the world. The HPN12XCM unit offers the best combination of portability, cooling comfort, intuitive control, and quiet operation among its competitors.

This single hose portable air conditioner provides 12,000 BTUs of cooling capacity. It can effectively cool most rooms up to 500 square feet, which makes it an excellent option for many small homes or apartments.

Not only the HPN12XCM portable air conditioner keep your room cool, but it can keep it cool with high efficiency. In fact, it has an efficiency rating of EER 9.5. We estimate its annual energy cost at $90.72, based on 8 hours of daily use for 3 months of the year. However, the cost can vary depending on your usage and power costs in your area.

Like most portable AC models, this on provides 3 distinct functions in one convenient unit: air conditioning, dehumidification, and fan. You can use the remote control to switch through these 3 modes. All portable AC units cool a room by pulling moisture from the air, but this particular unit can remove an impressive 100 pints of moisture from the air per day – the highest in our list. This unit has 3 settings for cooling and fan speeds which is a fairly standard feature for most portable air conditioners. Although looked at separately the room-size rating, energy efficiency, and moisture collection are average for the industry, together they make the HPN12XCM a strong contender.

The normal conversation between two people typically has a range of 55 to 60 decibels. In comparison, the HPN12XCM model has the noise level of 55 decibels, even at full blast. With the compressor off and the fan on low, the sound output is 49 decibels, that’s quieter than most oscillating fans. It’s a smooth, consistent background noise even when the compressor operates, making this ideal for light sleepers.

This unit also features an auto evaporation system that removes condensed water for more efficient cooling. However, it’s not a full evaporation system, so if you live in a particularly humid environment, you should expect to drain the water.

Weighing in at just over 74 pounds, this is the heaviest unit we reviewed. However, it is easy to install this unit. You can either place it on a corner of the room with its durable casters or use the window-installation kit that can accommodate a window of 20 up to 46 inches. It also comes with a 5ft exhaust hose which can be easily adjusted to the window for your convenience. The length of the hose is a bit longer than the hoses of other models, which provides versatility to where you can install the machine.

All in all, the HPN12XCM portable air conditioner illustrates how Haier combines from design and performance. It has a modern look that can be mixed and matched with any modern home style. It comes with a 24-hour timer that allows you to create a cooling schedule as well as conserve energy by not running all day. It also has an LED displays which are easy for the eyes to read.

  • Operates quietly
  • Lengthy exhaust hose and power cord
  • Low maintenance
  • Easy to install

SPT WA-1420E Portable Air Conditioner

If you are looking for a powerful yet affordable portable air conditioner for your room, then the SPT WA-1420E may be what you’re looking for. It is characterized by user-friendliness and more cheaper than other 14,000 units.

When it comes to cooling power, the product description states that this portable air conditioner is capable of cooling up to 700 square feet with 14,000 BTU. But some users claim that the unit cools a smaller space than indicated. In fact, some reviewers have indicated that the product can only handle up to 550 square feet.

In addition to cooling, it also features a dehumidifying mode and a fan-only mode. If you live in a humid climate, this model is well-suited for making your room a bit more comfortable. With the remote’s simple layout, it’s easy to switch from air conditioning to dehumidify to fan-only mode. In case you just want to remove excess moisture from the air, you can switch to the dehumidify-only mode. Like most other AC unit, the SPT has 3 fan speeds (low, medium, and high) to achieve and maintain your comfort level. The speed of the fan can be controlled from the control panel. You can also control the speed by using a remote control.

We also like the fact that this unit is not only powerful at cooling, but also eco-friendly. It uses non-ozone-depleting refrigerant – R410A and is made with all RoHS compliant components, signifying it meets industry standard for health and environment. On the plus side, this unit has an energy efficiency ratio of 8.9 ERR. Compared to the average among the energy efficiency units we reviewed, which is 9.5, the SPT model’s energy efficiency is relatively low. This means running this machine may cost you a bit more than others. However, the SPT WA-1420E operates at a fairly quiet 56 dbA, which is quite impressive for an air conditioner of this size and power.

As the machine comes with a self-evaporative system which can recycle the water it collects as condensate into additional cooling power. However, this is not a full evaporation system, if you live in a very humid area, you might need to remove some water or install a drain hose.

Overall, the SPT WA-1420E is based on a 3-in-1 technology to ensure your room has the desired environment. This eco-friendly air conditioner offers many convenience features such as a self-evaporative system, programmable timer, and digital display. The auto-restart feature ensures that the unit stays on after a power cut. Additionally, you can use the 24-hour timer to tell the SPT WA-1420E when to turn on or turn off at certain times of day without you needing to take any effort. SPT also includes auto-swinging louvers for those who don’t like having all the cool air focused on one spot. How useful this is will depend on your area, but it’s good to have the option.

EdgeStar AP12000S Portable Air Conditioner

If heat is just killing you, it’s time to stop this with the EdgeStar AP12000S air conditioner! Most AC units have tradeoffs, the most common being sacrificing energy efficiency for performance. This is definitely not the case with the EdgeStar AP12000S. This is a balanced unit that is not only powerful at cooling, but also energy-efficient and feature-rich.

Although not as powerful as the SPT WA-1420E, this unit can produce consistent airflow with enough power to contribute to the steady airflow of 169 cubic feet per minute. Boasting 12000 BTU capacity, the unit can instantly cool rooms down up to 425 square feet.

The EdgeStar AP12000S is designed to serve as a fan, a dehumidifier or simply as an air conditioner. It works as a dehumidifier with a dehumidifying capacity of up to 78 pints per day. Another great thing about this particular unit is that you have the choice of using it as a dehumidifier alone or you can have both functions working simultaneously. With the advantage of being used as a dehumidifier, the EdgeStar AP12000S portable air conditioner comes with a direct drain option so that the machine may continuously expel the water into a nearby drain in your area negating the need to manually empty the collecting bucket.

Despite its good performance, this EdgeStar model is one of the most efficient models we reviewed. This 12000 BTU unit has an impressive EER of 10 – which is the second-most efficient model among the units we reviewed, meaning it consumes significantly less energy than others in its class. Furthermore, this machine is an environment – friendly portable air conditioner as it uses no ozone-damaging R410A refrigerant and meets new RoHS standard. The RoHS directive aims to restrict certain dangerous substances commonly used in electronic equipment such as mercury, lead, and cadmium.

Just like some models reviewed earlier, this machine comes with an auto-drain system which means you will no longer have to manually drain the condensate in the slightly humid environment. However, under highly-humid climates, the unit still requires some water removal here and there. That’s because the water collected faster than the patented system could drain it.

The SPT WA-1420E portable air conditioner generates 56 decibels of noise, while this unit produces 53 decibels. How much of a difference do two decibels make? Well, not a whole lot if you plan to use this in a computer server room or a basement. However, the decreased noise output really masters in living rooms, bedrooms, or offices. If you are unfamiliar with how decibels work, the decibel scale is logarithmic. Basically, for every 3 dB increase, you’re adding 50% of your remaining sound pressure levels to your exposure. So even that small decrease of 3 decibels is perceivable if you place both SPT WA-1420E and EdgeStar AP12000S side-by-side in a relatively quiet living space.

Additionally, the EdgeStar AP12000S includes a washable pre-filter and one replaceable carbon filter, giving it some air purification capabilities. It also comes with a window kit that is simple to install.


  • Effective cooling
  • Energy Efficient
  • Eco-friendly
  • Quiet operation


  • A bit heavy
  • Average dehumidifying capacity

Honeywell MN12CES Portable Air Conditioner

The Honeywell MN12CES portable air conditioner is the final of the three Honeywell models discussed in this review. As mentioned above, Honeywell is an extremely old manufacturer. In its 133 years, it has had the time to innovate and perfect electronics design. The fact that three of its air conditioning units made it onto our lists tells you a lot about the quality of Honeywell’s products.

This Honeywell MN12CES model has a massive cooling capacity of 12,000 BTUs that lets the unit cool a 500 square foot room in a matter of 15 minutes. However, the effectiveness of the machine can sometimes be affected by the design of your space more so it space features large ventilation or openings.

Besides cooling, this particular model can be used as a dehumidifier to remove up to 79.2 pints every 24 hours. Add to this the fan only mode and you have an all-around machine that will keep the air indoors at a comfortable level all summer. The unit has 3 fan speeds: Low, Medium, and High. The 3-speed fan provides the maximum airflow of 163 cubic feet per minute.

During our MN12CES review testing, we found it to deliver the advertised powerful airflow and, for the most part, quiet operation of 54 dbA. Therefore, if you want a portable air conditioner that doesn’t keep you up at night, this model will be a great choice. Honeywell MN12CES also uses an auto-evaporation system so that you don’t have to manually drain the condensate every few days.

As would be expected from Honeywell, this model is aesthetically pleasing. With its two-toned black-and-silver design, it will add a touch of class to any room in the home or office. This stylish unit has dimensions are fairly small when compared with some other portable ACs, with measurements of 15.7 x 16.5 x 29.3 inches. It weighs in at just over 68 pounds and the lack of handles makes it difficult to carry the unit up and down stairs. But you can easily carry it from one room to another and continue enjoying a comfortable temperature. This is helped by four solid casters at the bottom to cart around between rooms.

Like other portable ACs, this unit comes with an easy-to-install window venting kit that reaches up to 47.2 inches, so you can attach the vent to small or midsize windows. Its vent hose extends up to less than 4 feet so you will need to place the machine no more than 4 feet from the window used for installation. The length of the power cord is only 3 feet which is a bit disappointing since it can limit the locations where you can install it.

If you’re environmentally conscious, you will be glad to know this unit uses the R410A refrigerant which is ozone friendly. Moreover, the unit also features a timer which allows you to run the machine only when it’s needed instead of all day and night. This means the unit helps you save energy in your home as well as reduce your AC bills over summer.


  • Sleek design
  • Powerful cooling
  • Easy to install
  • Fairly quiet
  • Eco-friendly


  • Lacks the handles
  • Short power cord

COSTWAY Portable Air Conditioner

Finally, we have the last small portable air conditioner on this list – the portable air conditioner from COSTWAY. The company was founded in 2008 with a commitment to provide customers with affordable options in every department. Although COSTWAY is younger than Whynter, it still grows into such a large company because of their cost-effectiveness.

The COSTWAY portable air conditioner hits a sweet spot when it comes to affordability, portability, and aesthetics. However, with the savings on cost comes with a significant drawback, in that it can only manage an area of up to 161 square feet, which is not a lot. Even so, we have listed the COSTWAY unit on this report since it does a great job in small areas and provides savings on both the unit and running costs. It is relatively energy efficient with an EER rating of 8.9.

The COSTWAY portable air conditioner comes in the dimensions of 12” x 13” x 24.5” (W x D x H). And it weighs only at 46 lbs which is something users find convenient. They talk about how easy it is to mode the AC from one place to another and utilize it to the max. Also, this unit comes with 4 caster wheels which means you can easily roll it from room to room without damaging the surface. You can use this machine comfortably in dorm rooms, small apartments, RVs and anywhere that you think you may have limited space. This unit is not only apt for the small spaces but also is very elegant and smooth to the eye.

Like most of the portable AC units, this model comes with different functions such as cooling, dehumidifying, fan and sleep mode. It boasts two-way fans that circulate the air in a more efficient manner for even cooling. Hot spots and drafts are eliminated with this feature. There are two-speed settings for more flexibility in how you can cool your room. However, the unit can get loud when you have the fan speed set to the high setting. Every mode and setting is easily accessible via an LED display panel. It also includes a remote control that you will have the machine set to whatever feature you like with a click of a button from across the room.

The COSTWAY portable air conditioner has some great features like the water-level check, water-full warning, the intelligent temp sensor and the 24-hour on/off timer which allows you to set the exact times you want your machine to turn on or off during the day. It includes an auto-condensate circle to more efficiently remove and recycle the moisture of your room. The filter slides out and can be rinsed under a faucet for you to have fresh and cool air constantly.

You will get a window kit to help you out with the easy assembly and a single exhaust hose that can extend between 11” to 5’ length. However, it does not come with a drain hose. You will either have to buy the drain hose separately to prevent the water mist accumulating, or you will have to place a drip pan under the draining vent. If you forget to empty the drip pan, you will find your floors to be soaked and damaged over time.

Overall, If you’re just looking for a basic portable air conditioner for your small spaces, then the COSTWAY portable AC maybe for you. It really isn’t much different from the previous products on this list, but it does cool a small space quickly and cost-effectively.
