Review on 🌬️ LEVOIT LV-H128-RF Air Purifier Replacement Filters - 3-in-1 Pre, H13 True HEPA, Activated Carbon, 3-Stage Filtration System, 2 Piece Set, LV-H128 Filter by Michael Eldridge

A few weeks after purchasing the filters, the power button LED turned red. I figured out what it means to replace and/or check the filter (maybe it wasn't adjusted properly, dirt got stuck in it, etc.). I wiped the filters, put them in every possible position, but nothing will turn off the signal light. I assume it improves air quality to some degree, but I don't recommend this product. It is quite obvious that it is not intended for Levoit products.
