#1 Levoit LV-H132 Air Purifier

The compact Levoit model measures just 2.9 x 2.4 x 1.2 ft and can filter up to 129 sq. ft. It’s an excellent inexpensive option that eschews technology like UV and ionization more commonly found in this price range. It features a three-stage filter system, which includes a prefilter, HEPA filter, and activated carbon filter. The purifier can be controlled by three fan settings, which allow you to control its speed and volume.

While this air purifier was designed for use in the bedroom (its fan is ultra quiet and it features an optional soft blue night light with two brightness settings), it’s quite portable and can be moved from room to room if needed. Aesthetically, it wouldn’t be out of place on your nightstand with its white or black case and sleek design. Though its capacity is on the smaller side and it doesn’t have as many features as other air purifiers on this list, it’s hard to beat the price.

#2 Coway Airmega AP-1512HH

The Coway Airmega Airmega 1512HH receives consistently high ratings. The compact air purifier has a four-stage filtration system that includes a prefilter, deodorization filter, and a Vital Ion filter. This helps remove 99.7% of contaminants from the air, including volatile organic compound and odor. While it’s filtering, it communicates your air quality in real time through its brightly colored LED display. And thanks to its auto mode, if it doesn’t sense any pollution for 30 minutes, the fan will automatically stop to conserve energy.

Because it’s small in size, this particular Coway model was designed to cover up to 361 square feet of space. For reference, that’s the size of a typical bedroom. If you’re looking for a whole-house air purifier, the Alen BreatheSmart is a better choice, but the Coway Airmega does an excellent job in smaller rooms and, with a decibel rating of 24.4 dB to 53.8 dB, it does it really quietly.

#3 Hathaspace Smart True HEPA Air Purifier 2.0

Hathaspace Smart True-HEPA Air Purifier 2.0 is essential for pets. This large capacity air purifier—it can replace the air in a 1,500-square-foot room up to 24 times per day—features a 5-in-1 filtration system that eliminates more than 99% of allergens and pollutants, like pet dander and the dust from a litter box. It also features an activated carbon filter to remove smoke, odors, and gases, and a cold catalyst filter to eliminate VOCs and harmful chemicals found within cleaning products and other household items like plug-ins or candles.

It features a washable filter that keeps pet hair from the HEPA filter, which improves performance and extends life expectancy. And, it’s easy to clean—just take it out, wash it down and it’s ready to start purifying again. It also has a filter replacement reminder that pops up to let you know when it’s time to order new filters, a convenient feature that ensures you never go without clean air.

#4 Alen BreatheSmart 75i Large Room Air Purifier

Are you looking to cover a lot more square footage? The Alen BreatheSmart75i Large Room Air Purifier is the perfect solution. This purifier can clean up to 1,300 square feet twice an hours without making too much noise. Alen claims that the BreatheSmart’s technology is twice quieter than those of its key competitors, even when it runs at Turbo speed.

The Alen BreatheSmart comes with a HEPA Pur filter that can capture 99.97% of particles down to 0.3 microns. This works in combination with the device’s Laser Smart Sensor, which also detects airborne particles down to 0.3 microns, to effectively clean your air of dust, pollen, allergens and dander.

It measures about 27 inches high and 18 inches wide, with a control panel on top that includes an air quality indicator light which always reflects the real-time purity of the room’s air with an easy-to-read display. And you can choose from among 14 different colors and panels to find one to match your home’s interior.

#5 Blueair Blue Pure 411 Air Purifier

If you’re looking for a snazzy looking device for modestly sized rooms, this Blueair model may well be the way to go. It’s designed for spaces up to about 160 square feet, and Blueair claims it can filter that space five times an hour.

This air purifier has three stages. It combines mechanical filtration with electrostatic filter and activated carbon filter to reduce odors. It comes with two washable filters that can be used to filter out smoke, pet dander, particles, and more. That said, be aware that while Blueair claims the system filters 99% of pollutants and it’s had its performance independently verified by the AHAM (Association of Home Appliance Manufacturers), the filter itself isn’t HEPA-certified, if you’re looking for that particular seal of approval.

Visually, Blueair made sure that this purifier doesn’t look like an ordinary appliance. It has an interesting design that splits the device into two contrasting colors—colors that you can change depending upon the filter you install. A single button turns it on, off and varies the fan speed, but there’s no display or status on the device, nor is there a way to set an on/off timer.

#6 Levoit VeSync Core 400S Smart Air Purifier

What’s so “smart” about the LEVOIT VeSync Core 400S? The model connects to the VeSync App, which allows you control the device and view real-time information about the air quality in the home. The unit can be connected to voice assistants and has an Auto Mode, which adjusts fan speed to maintain clean air and energy conservation.

The Core 400S offers all the essential features you would expect from an air purifier. It has a HEPA filter, which can remove air pollutants as low at 0.3 microns. It has a large cleaning radius, circulating air in rooms up 403 feet by five times an hour.
