Blueair 601 Series Particle Replacement Filter

Purchased these for my Bluair 601 after my normal internet search and these were the least expensive out there. Only one problem found and it is trivial: the visible portion that shows through the screening didn't match up to the screening and leaves a border around what is visible. Hard to explain and no big deal but does annoy. Will purchase replacements from this vendor when it is time to replace current filters.

I have been using blue air for several years. It really helps keep the dust and lint to a minimum.

I've owned the Blue Air 501 for 3 years and am totally pleased. I've tried others and I know that some are not worth trying (even though they are highly advertised and purchased). It's quiet and very effective.
