Review on 🏠 Purify Your Home Air: HEPA Filter Air Purifiers for Large Rooms with Pet-Friendly Odor Elimination, Super Quiet Sleep Mode - Ideal for Bedroom, Office, and Apartments up to 2500 ft² by Mia Lawrence

So I had high hopes for this machine but it did NOT meet my needs. Here's why: 1. Noise level. It's not as quiet as the one for sale. It is only reasonably quiet in the lowest settings. All other settings produce a fairly loud white noise, similar to a fan vibrating.2. Replacement filters are not available. Our device has been off for several months now due to no filters being available on Revain or any other website including the SELLER SITE!3. Cleaning efficiency seems basic at best. We keep the house clean, we only have a small dog that doesn't shed, no smokers etc. We just hope to "freshen" the stale air in the living room and dining room. But the device struggled to move enough air to get the job done unless the fan was constantly in one of the higher, louder modes. Final Thoughts: I'm still looking for an air purifier and probably won't try any other Kolser product.
