Review on Powerful True HEPA Air Purifier: Remove 99.98% Smokes/Dust/Pet Dander in 🌬️ Rooms up to 250~400ft² with Air Monitor & Digital Display During Night Light by Jen Slocum

This air purifier does a great job. I don't have any fancy devices to measure the true air quality in my room, but I can tell there is a significant difference. I recently got into 3D printing and have placed the printer in my office as I have no other place to put it. I recently had a cough that I could reasonably attribute to the printer (as it started when I got it and lasted 3 weeks). I finally bought this air purifier. Needless to say my cough has gone and the air quality in my room has improved.
