Winix Air Purifier, C535, 4-Stage Cleaning with 2 Years of Filters. Max Room Capacity 1776 sq ft.

This unit is so quiet you cannot even tell it's on most of the time. It's easy to use and maintain and definitely improves air quality. I originally purchased one of these for my elderly parents to help with their air quality in their home because they were both having issues breathing more than was typical. After getting this they found their breathing issues were relieved and thus I purchased one for my own home. I find that it definitely helps with my asthma and has alleviated some of my allergy issues. I'd recommend this product if you want an affordable and truly useful air purifier.

WINIX is very quiet, sleek design. Doesn't take up a lot of room. When it's running a blue light runs. When a red light comes on it showing you that there is something in the air that is not healthy. I'm not sure what that would be but the WINIX alerts you . In my case I had a water leak and walls and ceilings are open leading to the attic. So it's possible particles are coming in. That is the reason I bought the WINIX and it's working well.
