It’s tough to find an air purifier for just 500 square feet of space that doesn’t skimp on powerful pollen, allergen and dust management. Many manufacturers make very weak versions of their larger and more powerful purifiers when it comes to making units rated for just 500 square feet. But we have found some quality products that are not only designed for smaller spaces, but don’t compromise on filtering capability. Take a look at our list of the best air purifiers for 500 square feet.
Best Air Purifier for 500 Sq. Ft. Comparison
Best Air Purifier for 500 sq. ft. Reviews
By far the most affordable purifier on our list, the Silver Onyx offers table-top air purification with features that even larger units don’t have. It comes with dual-filtration (true HEPA and activated carbon) and an ionizer for killing bacteria and harmful spores. The 2 fan speeds are operated by a quiet direct current motor. And because it only stands a foot high and 9.8 inches wide, it’s perfect for desks or tables in rooms up to 500 square feet.
- Very lightweight (4.7 pounds)
- The ionizer reduces static electricity
- Built-in air quality sensor
This same model can be purchased for 650 square foot coverage but we are reviewing the 540 square foot coverage version. This unit features an outer, mesh pre-filter for collecting larger debris, a particle filter and a carbon filter for annoying odors. This is a good purifier if you are worried about volatile organic compounds and odors from cooking or smoking. It drastically cut down on odors from our kitchen and even from our pet. Furthermore, the Blue Pure 211+ draws in air from all 4 sides of its rectangular design. It moves a lot of air and the effects are noticeable almost instantly.
- You can choose different colors for the outside mesh filter
- The filters are easy to change
- Great for trapping dust – makes the air easier to breathe
The BreatheSmart Flex is actually rated to purify air in 700 square foot spaces but we added it to this list because it is very reasonably priced and more than adequate for 500 square foot spaces. It has a sleep and “lights out” mode too so the fan won’t disturb you at night if you decide to put it in your bedroom. This is a great option if you need a purifier to trap pollen, pet fur, dander, allergens and dust. Plus, the true HEPA filter lasts a very long time.
- Operates very quietly on sleep mode
- The front panel can be customized
- 4 different fan speeds

The most immediate benefit that we noticed with the air purifiers that we tested above was that they made the air easier to breathe almost immediately. They have a near-instant impact on the quality of indoor air. They also help to alleviate seasonal allergy symptoms and remove a significant amount of dust particles from the air.

If you change the filters as directed and choose purifiers that produce little to no ozone, they should not make you sick.
