Review on 🍃 LEVOIT Core 300-RF-TX Air Purifier Toxin Absorber Replacement Filter - Green, 1 Pack | 3-in-1 True HEPA & High-Efficiency Activated Carbon by Robert Ryokan

Although I live in a "clean" city and prefer to keep my windows open at all times of the year, nobody could convince me that I was allergic to anything -or. Due to the occasional stuffy nose, sore throat, sinus issues, and possible COVID symptoms, I bought a 300 and closed all the windows. after 3 days all symptoms had disappeared. I checked it 3 times. I opened the windows and the symptoms returned throughout the day, closed the windows and the symptoms went away. It runs 24 hours a day, 7 days a week at the lowest speed, foot traffic and regular door traffic as I expect the air to circulate perfectly.
