Review on 🏡 2 Pack RENPHO Air Purifier for Home Bedroom Allergies and Pets Hair, H13 True HEPA Filter, 99.97% Odor, Smoke, Mold, Pollen, Dust Elimination with Advanced 3-Stage Filtration System by Sue Taylor

There is a sleep mode, but the other modes are also quite quiet and do not distract from watching TV or listening to music. However, the sleep mode is almost soothing, like white noise. The design is well done as older air purifiers had complex composite filters that were difficult to unload. In this case it is below, and removing the plain panel opens access. The filter is a one piece piece with a thoughtful design that is convenient and snaps easily as it conforms to the shape of the device itself rather than being inserted into a dedicated slot. This has worked well in our bedroom and den, both areas where cats are active, and also in the den where we had a lot of dust due to construction. My only suggestion is that while the power button toggles between different speeds, you have to hold the power button for a few seconds to turn it off, while the next mode could just toggle to "off" or maybe not require the same time to turn it off.
