What is it's purpose?** A: This is the black carbon filter that comes attached to the HEPA filters you buy. It is what collects a lot of physical dust and things and keeps the HEPA filter (which is much more expensive) lasting longer. I can usually change this carbon filter out twice for every HEPA filter change out. **Q: how do you install these do you attach to the orginal filter via the velcrow?** A: Do I put it in the front or back of the filter holder? I read it can be done either way. Had it in the back, then front. My fish aquarium back and the fish are healthy. **Q: Do you have to buy these as well as the hepa filters or will the hepa filters alone be sufficient?** A: I use both. I change these pre-filters every month, which I find to extend the life of the hepa filters. There are smokers in my house, I run my unit 24 x 7, and when I change the pre-filters I was amazed at how filthy they were. Hope this helps answer your question... **Q: Removed old filter. Light is still flashing red after new filter replacement. Anyone else having this issue??** A: On the top of my GermGuardian it says to hold the UV light button for 5 seconds to reset the filter light. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Exactly as described *by C***L on January 4, 2026* Exactly what was described, these filters work great with my Germ Gaurdian air purifier.
