What is the Honeywell HEPA Air Purifier?

HEPA air purifiers are the gold standard in the air purifier market and this particular Honeywell HEPA air purifier model makes it easy to see why. It comes with four filters to capture nearly all of the airborne pollutants (99.97%, 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. Say goodbye to those pesky seasonal germs!

Why We Love It

At only 17 pounds, it’s easy enough to haul room-to-room. This is made especially so thanks to the inset handles on either side of the device. FYI: It’s a little bigger than some of the other models out there at 20 inches tall, but it can still be easily tucked in a corner.

The control panel is easy to navigate and features indicator lights for filter changes and three different cleaning modes: Allergen, General Clean and Germ. The boosting “Turbo” mode works well for very low-quality air—think smoke, smells or pet accidents. In addition, there’s a handy dimmer button for nighttime.

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.

What Other Reviewers Are Saying

Of course, all of that sounds good in theory. But just how good is it in practice? Allergy sufferers, by far, are Honeywell’s most devoted and vocal fans.

“My chronic allergies and sinusitis have required that I use HEPA air filters in every room of my home. Over the past 20 years I have owned many different units, almost all of them were manufactured by Honeywell. While all had the same basic functions and worked quite well, this unit is by far the best and quietest air filter that I have ever owned,” writes reviewer Tom F.

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% 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 run it on Turbo mode during the day and low at night—and wow, at all the stuff it sucks in,” writes one happy customer. “Our room smells crisp and clean and I don’t see dust anymore anywhere. I recommend this to everyone I talk to who has pets dealing with health issues, especially breathing ones.”


How long do Honeywell HEPA filters last?

While the HEPA filter needs replacements every 12 months, they’re relatively inexpensive at around $20. Filter swaps are far less frequent with this device than other HEPA air purifiers we tested, which usually end up being around every six months on average.

How do you know if a HEPA filter needs replacing?

In general, HEPA filters should be replaced every six to 12 months, according to the manufacturer’s instructions. HEPA filters need to be swapped out when there’s a clear buildup of dust and dirt. Some air purifiers require folks to peek inside the unit to check this metric, but Honeywell air purifiers include an indicator light on the machine that lets you know when it’s time to swap out the old HEPA filter for a new one.

Can you leave Honeywell air purifier on all the time?

Unlike ionizers, HEPA air purifiers don’t produce ozone, so they don’t have any negative effects on health. Feel free to run the air purifier for as long as you’d like!

Where to Buy It

At around $200, the Honeywell HEPA air purifier is not cheap—but it’s less expensive than many models out there and works as well, if not better, than pricey competitors. Plus, according to user reviews, the device lasts through several seasons. Some reviewers claim that they’ve had one for over two years!

Snag it from Amazon, Walmart or Ace Hardware and stop breathing in allergens for good.
