BHG Readers Who Try Our ‘Best Overall’ Air Purifier Are Loving It—and Right Now It’s on Sale at Amazon

Don’t be fooled—allergy season is far from over. Outdoor allergens don’t just dissipate after the early months of spring; in fact, according to the Asthma and Allergy Foundation of America, many allergy symptoms can actually worsen from summer to fall because grasses are the most common trigger for hay fever. And right now is when pollen from ryegrass, timothy grass, and ragweed starts circulating. One of the most effective ways to cut back your allergy symptoms is by using an effective air purifier.

While you may not find yourself face to face with any grass indoors, air purifiers are a must because pollen particles are tiny enough to sneak inside. These micron-sized particles come in through open windows, doors, and even attach to your clothing (and pets!). If your primary concern is finding relief from outdoor allergens, try the Levoit Core 400S Smart Air Purifier, which we named our “Best Overall” air purifier after testing. This BHG favorite also happens to be on sale for $185, which is the lowest price we’ve seen in the past month. 

Levoit Core 400S Smart Air Purifier

During testing, we were initially impressed by the Levoit Core 400S’s ability to improve the air so much that the air was actually cleaner than the controlled room before pollutants were introduced for testing. And even after using it for six months, this air purifier continued to impress testers.

This air purifier has two main settings (low and high) and several modes, including auto and sleep. It’s Energy Star-certified, which means it’s kinder on your electric bill (and the planet), and it pairs with an app for smart controls like voice activation and scheduled timers. You can also check the filter’s health, too. But the feature you’ll likely love the best is its whisper-quiet noise level. It barely makes any noise at all, which means it won’t keep you up at night.

Being that we recommend the Levoit Core 400S Smart Air Purifier as our “Best Overall” pick for an air purifier, we kept an eye on what other users thought and checked the Amazon reviews. We’re happy to report that, yes, shoppers are buying the Levoit Core 400S as a result of our recommendation. 

“I bought one after reading a Better Homes & Garden article that reviewed several brands of air purifiers. This Levoit 400 was highly rated. After using it for a year in my living room, I bought a second one for my bedroom,” a five-star reviewer wrote. “I have allergies and this definitely makes a difference in helping with the dust levels in my home.” 

They added that the purifier is “very quiet while running,” and they frequently run it on auto “which is the best setting to use because it will automatically adjust to whatever the air quality is at any given time.” The same reviewer also said that the purifier is easy to clean; they simply use “a hand vacuum to keep the outside of [the purifiers] clean.” They added, “I highly recommend the Levoit 400!”

Of course, other shoppers love it, too. One mentioned that allergies, smoke, and certain smells trigger chronic migraines, but the symptoms were quickly alleviated after they started using the Levoit air purifier “I got the unit almost two years ago, and use it almost 24/7,” they said. “I can’t say enough how much I especially recommend this to anyone with migraines. Smell sensitivity can be extreme for some people during a migraine attack. Since having this, I… sequester myself next to my purifier and at least get relief from that part of the attack.”

We named the Levoit Core 400S Smart Air Purifier the best option overall in our test of over 90 air purifiers for good reason, and after taking our recommendation, it’s clear that shoppers agree.
