Honeywell HHT-011 HEPAClean Compact Air Purifier

Honeywell HHT-011 is most effective in small rooms like kitchens, offices, andHoneywell HHT-011 bedrooms. It features a 3-stage filtration system, which uses a washable pre-filter to capture larger particles and a long-life HEPA-Type filter that helps capture up to 99% of airborne particles from the air that passes through the filter. The HHT-011 can be placed horizontally or
vertically and features 3 settings.
The built in cleaning reminder lets you know when it’s time to clean or replace your filter, so you can always benefit from the strongest filtering possible. Designed to keep the air in an 85 sq ft room constantly clean and filtered, this purifier is perfect for apartment living and providing a safe zone in allergy season.

The Filter

There a need to address this issue first because there were a lot of negative reviews on the Honeywell HHT-011 air purifier regarding its HEPA-type filter. What you should know is just because it says permanent filter on the box, it doesn’t mean you should forget about its existence and go about your day.
The permanent part means you don’t need to replace the filter every time it collects enough dust and particles. You simply wash it, let it dry and then put it back into the purifier. Even so, you still need to replace it with a new one, but that interval is measured in years rather than days or months. The permanent HEPA filter in the Honeywell HHT-011 is able to filter almost 99% of pet dander, smoke, pollen, mold spores and dust. What’s great about this particular model is it comes with a light indicator that lets you know when it’s time to clean the filter so no more guess work for you!

Honeywell HHT-011 Space Saving DesignHoneywell HHT-011

Falling in line with its unobtrusive sound is the Honeywell HHT-011’s design that makes it suitable for pretty much any room. Compared to some larger units out there this one doesn’t get in the way, and with dimensions of 9.40 by 5.8 by 12.9 inches you won’t have to re-arrange furniture in order to accommodate its size!

Noise Levels

When it comes to noise the Honeywell HHT-011 Compact air purifier fares pretty well. You can choose between three different settings: low, medium and high. The unit is very quiet when set on low which makes it great for use in a bedroom. Even the medium setting is pretty tolerable if you’re not sensitive to a bit of some noise, in fact you’ll most likely forget about it being there when using it during the day.
It does get a bit loud when set on high, but you only need this setting if there is a large concentration of dust in the room, or a bad smell you need to get rid of quickly. My advice would be to use the first two levels when you’re at home, and set it to high when you’re not around. Although for many people this isn’t an issue.

Air Changes Per Hour (ACH Rating)Honeywell 50150 Pure HEPA Round Air Purifier (3)

With an ACH rating of 5x, the Honeywell HHT-011 performs in-line with top air purifiers such as the Alen BreatheSmart and Whirlpool Whispure 510.

Clean Air Delivery Rate (CADR Rating)

CADR ratings for the Honeywell HHT-011 are unfortunately low – ratings for dust / smoke / pollen are only 55 / 55 / 65. This means that the air purifier offers basic protection and will definitely improve the air quality in your house, but will probably not completely remove even common air pollutants. Small air contaminants such as germs, bacteria and mold spores would not be filtered out.


Average energy usage of 102 Watts is slightly above average for air purifiers and high for its size.


With a 3-year warranty, this Honeywell air purifier gives you sufficient peace of mind.

In conclusion

The Honeywell HHT-011 compact air purifier is a quiet and powerful air purifier with no filters to replace. It will keep your room smelling good and dust free. I would recommend it to anyone who has a small flat, and doesn’t want to buy new filters and is perhaps on a budget. This air purifier is available on Amazon at a convenient price.
