Review on 🔳 4-Pack Carbon Activated Pre-Filter for Germ Guardian FLT4825 HEPA Filter, AC4800 Series, Filter B - By Complete Filtration Services by Travis Carter

Reasonable price for a filter. The original GermGuardian is a bit overpriced. The red light flashed after three months. I checked the filter. There was a lot of dust and small light-colored particles on the filter. Look at this picture. For example) I vacuumed my room every two weeks so I didn't do it except my room had a lot of dust. I removed the original filter and replaced it with a CFS filter. It was slightly longer than the original filter, but there were no problems installing it. After the replacement, I pressed the UV button for 3-5 seconds to reset the indicator (red to green). Please check all photos here.
