Review on 🌬️ Enhance Air Quality with Genuine HEPA FLT4100 Replacement Filter for Guardian Technologies GermGuardian AC4100 Series Air Purifiers by Timothy Hughes

This is a HEPA air filter for the unit I use in my bedroom at night to help me sleep. After about 6 months of use I had to replace the worn out filter with a new one. This fits the bill. I think it cleans and filters the air, the filter looks shabby in fights. So put a new one in and I think it does its job and cleans the air I breathe. I don't know if it works against Covid or not, but I don't risk it. Thanks to two working air filters, both HEPA and my air conditioner at home with a HEPA filter, my indoor air will be fresh and clean.
