I have had many brand Air Filters over the years. Right now I have a large Honeywell and four IDYLIS. Having cats in the house is why. Most are near litter boxes and one in the hallway that is by the Kitchen And Living Room. I found myself needing another one and when I saw the specs and the features it had it looked good. Now one of the best things going for this one is the price of the replacement filters. As of this writing they are $20.99 Living Enrichment Air Purifier, spare filter 200 CFM and up for pre-order. Not a bad price.The controls are on the top are easy to read and use. There is a colored ring on top to indicate overall air quality. I like what I am seeing so far of this unit and will likely purchase another if the price of the filters don't get out of control.Update: 03/08/2023 I have had for Seven months and need a replacement filter, still not able to order. Docking Two stars until filter is available.Update 06/02/23 Still can not order a replacement filter. Do not buy! removing all stars if I could.Update #3 03/21/24 Still can not find replacement filter. Avoid this product.
