Perfect fit and quality for less money ✅💰
The media could not be loaded. These replacement filters for the Blue Air 311i Max deliver exactly what I needed. The functionality is excellent they trap dust, pet dander, and odors effectively. It is easy to slide right into place without any struggle and the size is perfectly compatible with the blue air 311i Max just like the original filter.The quality feels premium the materials are sturdy, and the layers of HEPA and activated carbon are dense and well-made. I also appreciate that it comes in a 2-pack, which adds a great value for money , especially compared to the branded replacements.Highly recommend for anyone looking for reliable, high-quality filters that don’t break the bank!

Filters for mini air humidifier
It worked out fine.It was just about 2inces longer, but I fixed it. I had to trim it.The one I have is the correct model but it is little smaller. So that's why I had to cancel the subscription. I will order in 6 mos but with the smaller filter

Doesn’t Fit and Smells!
Filters are oversized for the BlueAir 311 and give off an awful rubber smell. Not a usable proct and obviously made in China
