Haven’t washed one yet
But it fits great & so far I’m completely satisfiedShaking my head ruefully at the customers who can’t put it on correctly by giving a gentle tug, but I’m assuming they’re just trying to get it for free??

a ood filter
The Blueair filter works very well. The cost of the exterior filers is ok.

Doesn't fit Blair 411
The prefilter is too small to fit the blueair 411. The fabric does not stretch to cover the air intact holes. I had to cut & sew 3 inches from one of the filters to make them fit. I plan on buying the name brand next time. Not worth the money

Fancy covering
Nothing but a dust cover. Doesn’t wash well-nylon catches on everything. Definitely need more than one

Too small
These do not fit the 411 properly. The material is thin and cheap and doesn't wash well. This is not equivalent to the ones that come with the 411.

they too short
Looks like the material is ok. They just too short. 3.0“ too short. I bet much shorter after washing it.
