Cobectal H14 HEPA Air Purifier ZQA-6000A with Activated Carbon Filter for Smoke, Dust, Pollen, and Dander

This air purifier is great exactly what I needed. My son has seasonal allergies pretty bad so I run this during the day areand I feel like the air inside my house is so much cleaner. His allergies aren't acting up like usual, it looks nice, and it's very quiet. Definitely would suggest anyone to buy this.

Easy out of the box set up. Works well with differing fan speeds and has particle concentration display and filter life display. So far seems to do a good job with no issues.

This works as described, it doesn't take up much room, and arrived quickly.

I've bought three of these now. The first one worked and still works, but is now making a noise after only a month. I bought two more before it started making noise and neither one that arrived worked. The first one had the power receptacle too far into the housing to accept the power cord. The second one never registered any air pollution and never helped the other filters I have. I sat it next to an air meter and it did nothing after a few hours.
