So far so good!

The air in my office is noticeably cleaner. My allergy symptoms have subsided dramatically since I started using the Honeywell Tru HEPA Whole Room Air Purifier.

Quiet and effective

I was surprised by how quiet this air purifier is compared to others on the market. Sure, the turbo setting is loud, but that's understandable, and you only need to use it every so often. The purifier is simple and effective, it's really just a fan sucking air through HEPA filters, which is all you really need ie, no ozone like you get with ionizing purifiers. So far, so good.

Helps with sleeping

We bought this air purifier during the height of covid, just wanted something running in the background in our bedroom. After covid now, we found this purifier to help us sleep. It kept our air fresh in the winter when it was hard open windows. I definitely would recommend this to others.

Love my new air purifier

My new honeywell air purifier has been an excellent purchase. Has helped relieve my allergy symptoms. The turbo setting is a bit loud but all 3 other settings are just fine for my 500 sq ft open air LR/DR/Kitchen set up. I purchased this after reading reviews on it by consumer report

I purchased this air purifier after receiving great feedback and reading reviews. My daughter who has allergies has noticed a difference almost immediately.

Works very well

The unit works as well as described. Unfortunately one of the clips holding the front cover was broken. This does not impede the extremely well working unit.

System is running fine. Using in my sewing area where I sew, cut, press for about 4 hrs a day. Feel it is already making a difference with the finer dust

Absolutely love this filter! I have severe allergies and asthma and could tell that night it made a big difference. I like that I can dim light.
