With a pandemic caused by airborne respiratory droplets, a longer-than-usual fire season and more time spent inside, it’s no wonder air purifier sales have jumped over the past year. When you also consider household air pollution causes around 3.8 million deaths worldwide every year, you might wonder why you didn’t get an air purifier sooner.

Don’t have one yet? There’s no time like the present! But with so many models on the market, how can you choose the best air purifier for your needs?

Of course, it’s important to look at the features, price, and maintenance required. We get the inside scoop on the best products by seeking out frequently rated models. That’s how we discovered this Honeywell True HEPA Air Purifier that has more than 7,800 five-star reviews on Amazon. Learn why people love it so much and you just might become its next superfan.

It Removes 99.97 Percent of Airborne Particles

HEPA air purifiers are known as the gold standard in the air purifier market, and this particular Honeywell model makes it easy to see why. It comes with four filters to capture nearly all of the airborne pollutants (99.97 percent, to be precise) floating around the room where it’s located.

The pre-filter traps larger particles such as dust, pet fur, VOCs, and cooking and smoke odors. Then the True HEPA R filters catch the 0.3-micron or larger microscopic allergens. If you’re struggling with airborne pollutants, it can’t hurt to decorate your space with these low-maintenance air-purifying plants, either.

It Circulates Air Up To 120 Times per Day

The Honeywell True HEPA comes with an “auto-off” timer you can set for two, four or eight hours. But as long as you keep the Honeywell switched on, it can circulate the air within the room five times per hour.

One reviewer runs it on “Germ,” the lowest setting, for eight hours each night, and says the quiet hum acts as a pleasant white noise. At other times of the day, “Allergen” and “Turbo” go on. Both are louder but circulate air more quickly. If you have an extra-large room, this air purifier is particularly perfect since it covers so much ground — 465 square feet, or the equivalent of a 20-ft. x 20-ft. room.

FYI: It’s a little bigger than some of the other models out there, but it can still be easily tucked in a corner. If you’re looking for a combo air purifier and humidifier, check out this list of the best humidifiers for 2021.

People Swear by It

Of course, all of that sounds good in theory. But just how good is it in practice? One woman raves that her family has gotten sick less frequently since she bought it. But allergy sufferers, by far, are the Honeywell’s most devoted and vocal fans. “I have seasonal allergies, and when the air purifier is operating, I FEEL the difference,” writes one reviewer.

Others claim their coughs disappeared and their seemingly constant sniffles subsided. Pet parents whose fur babies cause those allergies even report a huge improvement.

Experts agree. A March 2018 Cascade Survey Research survey found 69 percent of allergists polled recommend Honeywell air purifiers above all other brands due to their ability to effectively and rapidly clean the air.

The cleaning doesn’t just stop with your air, either. It has a ripple effect, so it ends up making the whole area cleaner, too.

“I have noticed less dust on my furniture, and the air in my home just feels lighter,” writes one happy customer. “I just changed the carbon filter and it was totally disgusting — I just couldn’t believe how filthy it was. It had pet hair along with dust and lots of it. I’m so glad it was on the filter and not in my house or worse yet in my lungs!”

Pet parents should also get one of these best vacuums for dog and cat hair.

You Get a Lot for Your Money

Plus, it’s a good deal. At $225.99, it’s not cheap. But it’s less expensive than many models out there, and it gets the job done just as well if not better.

Reviewer Tom F. writes he looked at nearly 20 units in the $200 to $600 price range and checked Consumer Reports and Amazon consumer feedback. Honeywell won him over because of “the price, the basic method of filtration, the very cool control panel, the fact that I could place the unit against a wall, the convenient size of the unit, and finally my positive experience over the past 20 years with Honeywell products.”

Just Keep These User Tips in Mind

While users rave about this air purifier, it’s important to note that they require frequent filter changes to work effectively and last as long as possible. Ideally, you should replace the pre-filter every quarter and the other three filters once per year.

While the Honeywell does have a “Change Air Filter” light, it’s still a good idea to set a calendar reminder on your phone or write a reminder on a piece of tape (stuck to the machine), with the date of the last filter swaps. Better safe than sorry!
