(Red light flashes indicating filter needs to be changed.) I don't see a reset button.** A: You have to push and hold the UV Control Button for 5 seconds to reset the Filter Change indicator. **Q: do we only need this filter? it has the black and white part? or do we need to buy another one?** A: Yes you do need to buy another one...But if you keep cleaned off it will last about a year...I love mine so much bought another one ,because I live in 2,000 sq ft... **Q: Can the pre-filter be sprayed off with water? We use it next to the cat litter box and it gets dusty fast!** A: I don't recommend it. The filter will crumble and fall apart (i've tried!). What I normally do is get a disinfectant wipe and wipe the filters down. I have cats too and mine is also relatively close to the liter box. **Q: how often do I change filter?** A: I thought the sign signal would come up to replace? Or you just replace without the sign coming up? I had mine for more than a year and I haven't changed the filter because the sign never came up? I don't use it all day just when the kids are in the room mostly during night time and it is in low. Could that be it? Should I have it on even when the kids are not in the room? ## Frequently Bought Together - GermGuardian Filter B HEPA Pure Genuine Air Purifier Filter, Removes 99.97% of Pollutants, Wildfire Smoke, Odors, for AC4825, AC4300, AC4850, AC4880, AC4900, CDAP4500, AP2200, Black/Yellow, FLT4825 - Germ Guardian FLT5000 True HEPA Genuine Air Purifier Replacement Filter C for GermGuardian AC5000E, AC5250PT, AC5300B, AC5350B, CDAP5500, and More - Germ Guardian FLT4100 True HEPA Genuine Air Purifier Replacement Filter E for GermGuardian AC4100, AC4150P, AC4150BL, and More --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/1143665-air-purifier-filter-b-genuine-hepa-filter-replacement](https://www.desertcart.us/products/1143665-air-purifier-filter-b-genuine-hepa-filter-replacement) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-11-13*
