Not colorful
Pointless color change, I wanted to have a nice green for my son’s room. But I wasted money because you can barely tell it’s green. It just looks like a different shade of the grey we already had. No pop of color when you walk into the room. It wasn’t horribly expensive and it fits, so just taking off 2 stars.

Thank you for sharing this feedback. We’re sorry to hear the Moss Blue Pure 511i Max Fabric Pre-Filter didn’t deliver the vibrant look you were hoping for. We truly appreciate your honest input—it’s important to us, and we’ll be sure to pass this along to our product team as we continue refining our color offerings. We're glad to hear the fit was right, and we hope your son enjoys the clean air!

Keep your air cleaners if you can't supply filters
Bought a max and a mini max and it's been almost 4 months ago and this company doesn't have pre filters for them. I bought a selection of ONE for the max but 0 for the mini. Why are you still in business?

Thank you for taking the time to share your feedback regarding the pre-filters for our 511i Max and Mini Max units. We sincerely apologize for the inconvenience you have experienced with the availability of these pre-filters. Please rest assured that we are working diligently to replenish the stock for both the Max and Mini Max units as soon as possible. In the meantime, we would like to inform you that the pre-filters are washable, which can help extend their usability and reduce the frequency of replacements.
