isinliveReplacement Filter Compatible with Blueair Blue Pure 411, Fits Blue Pure 411, 411+ & MINI Air Purifiers, Particle and Activated Carbon

We bought an air filter after bringing my daughter home from the NICU. The filters were easy to change and work great!

There's a lot of generic replacements listed, some on the super-cheap end of the spectrum. The cabiclean products are high-quality and good value, and strike a nice balance between avoiding the overpriced OEM versions and the cheapo knockoffs. Filters are not exactly the same, and you can see some minor work defects (like extra glue between the attaching pleats), but none that seem to affect quality.The real test is -- how "dirty" do they look after 3-6 months of filtration? And the answer there is pretty clear -- they are quite grey (at my house) and look like they've trapped just as much fine particulate as the OEM versions. So it seems to be just as good, but you should obviously try it out for yourself and make your own judgments!
