Instant Air Purifier 300
From the makers of the wildly popular Instant Pot, the AP300 doesn’t use much power, is easy to maintain and clean, and performed well removing VOCs in our purifying tests.
Dreo Air Purifier Tower Fan
The Dreo Air Purifier Tower Fan is a 2-in-1 design that quietly cools and purifies. It pairs with an app to provide historical air quality and temperature data.
Coway Airmega 250
Another great option we tested from Coway. The 250 was one of the best removers of particulate matter. It also used minimal electricity, thanks to the fan that adjusts based on the air quality. However, it didn’t perform well at removing VOCs from the air.
Coway Airmega 400 Smart Air Purifier
The Coway Airmega 400 Smart Air Purifier is an attractive air purifier that barely makes any sound and adjusts the fan speed based on the air’s pollution level.
Shark NeverChange Air Purifier Max (HP301)
We tested a larger, pricier version of the Shark NeverChange Air Purifier Max and were impressed with its purifying performance in our tests. This model is virtually identical but designed for medium-sized rooms.
Blueair Blue Pure 211+ Air Purifier
The Blueair Blue Pure 211+ Air Purifier filters the air in medium-to-large rooms up to five times per hour, and it’s so quiet that you won’t notice it’s operating.
Air purifier FAQs
Are air purifiers worth it?
Yes. Even the worst air purifiers improved indoor air quality when we tested extensively for our best air purifiers guide.
What does HEPA mean?
HEPA stands for “high-efficiency particulate air.” HEPA filters are the gold standard for air purifiers. According to the EPA, a HEPA filter can remove at least 99.97% of 0.3-micron airborne particles, which include pollen, bacteria, mold, and dust. We primarily only recommend air purifiers with true HEPA filters.
Can air purifiers help with wildfire smoke?
Yes. An air purifier can help during a smoke emergency. Experts recommend running an air purifier with a HEPA filter, like one of our top picks from Coway or Lasko. One of the best air conditioners with a good HVAC filter can also supply some relief.
