Replacement Filter Compatible with Blueair 500/600 Series Particle Filter

I use these with a Blue Air purifier. They work fine. I like the fact that they have a long life because of the price. I do vacuum them from time to time. I don't see much dust or junk on them when I do. I live in a very dusty area. Anything to keep the allergies down. Would recommend and buy again unless I find them for a better price.

Good filters at a nice price point compared to the name-brand versions. They fit with no problems and there are no gaps in the air flow or rattling from poor fitment. I have not noticed any issues in air quality after the change.

Does its job!

I haven’t had these filters long enough to know if they will last as long as the Blue Air brand; these fit, but there is a white “frame” around the top one that the Blue Air brand doesn’t have. I’ve tried to blacken it in with a marker, but haven’t been completely successful. They are 25% cheaper than Blue Air.

I bought this system years ago and because it's a simple design it doesn't break down and is easy to run and keep . It is not too loud while it's running and my dad, who is allergic to my dogs, can come to my house and not be affected. Wonderful product. Shipping was fast and product was as expected- happy with my purchase, will purchase again!
