GermGuardian Filter N HEPA Pure Genuine Air Purifier Replacement Filter, Removes 99.97% of Pollutants GermGuardian Air Purifier AC5600, FLT5600

I needed to replace the filter in my germ guardian air purifier and germguardianoutlet.com had the cheapest ones. When I replaced it there was stuff I couldn’t believe was in the air that was in the filter! I just can’t figure out how to reset my air purifier so the light that signals to replace filter turns off! Oh well I guess when I see the dog hair and dust sticking out from the sides of filter I’ll know it’s time to change!
