Buying Guide to the Best Portable Air Conditioners
We conducted research to determine the most important factors to help you learn all about portable air conditioners and find the ideal model for your situation. Read our buyer’s guide below to learn more about the most critical factors that go into purchasing a portable AC unit.
Cooling Power
The cooling power of a portable air conditioner is measured in British Thermal Units (BTUs). Portable air conditioners typically have a cooling power between 7,000 and 15,000 BTUs. The larger a room, the higher BTU output your unit will need to cool it.
Noise
We’ve found that portable air conditioners can be noisy while they’re running, especially when compared to permanent central air conditioning systems. If you’re easily distracted by noise, we recommend purchasing a portable air conditioner that features noise-suppression technology to keep it running below 60 decibels.
Settings
Some portable air conditioners can do more than cool a space. Many feature fan, dehumidifier, and heater settings. This makes them useful all year round.
Filter
Most portable air conditioners feature a filter that removes contaminants from the air they’re cooling. Common filter types include:
- Activated carbon: This type of filter removes smoke and odor from the air. It has to be replaced every few weeks because it can’t be cleaned.
- Antimicrobial: This filter traps small molecules, such as pollen and dust, and prevents bacterial growth. It can be cleaned, but it should still be replaced three to four times per year.
- Electrostatic charge: These filters also trap small molecules, but they must be replaced every two to three months.
- Pre-filter: This filter traps large pieces of debris, such as pet hair. It can usually be cleaned.
- Silver ion: These filters remove allergens and other irritants in addition to breaking down larger pieces of debris. However, they have to be replaced more frequently than the other types of filters.
Other Features
Additional features that our research indicted can improve the effectiveness of a portable air conditioner include:
- LED displays
- Temperature control settings
- Exhaust hoses
- Storage bags
- Remote controls
Frequently Asked Questions About Portable Air Conditioners
How do I know what size portable air conditioner I need to cool my room?
To find the best-sized portable air conditioner for you, we recommend starting by measuring the area of your room in square feet. From there, you can calculate the needed power using this chart:
- 200 square feet or smaller = 8,000 BTUs
- 201–300 square feet = 10,000 BTUs
- 301–400 square feet = 12,000 BTUs
- 401–450 square feet = 14,000 BTUs
- 451–500 square feet = 16,000 BTUs
How often do I have to clean or replace the filter of my portable air conditioner?
It depends on the type of filter that your portable air conditioner uses. Activated carbon and silver ion filters can’t be cleaned, so they have to be replaced every few weeks. Electrostatic charge and antimicrobial filters can be cleaned to extend their lifespan, but our research shows that they should still be replaced every three months.
Where in the room should I put my portable air conditioner?
We’ve found that the best place to store your portable air conditioner is in a spot where it can effectively cool the entire room. Many units include installation kits for placing them on windowsills or underneath windows. Other popular locations include in corners and against walls.
