Replacement for 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!

We like that these filters fit our unit & work well at a significant savings over the manufacturer’s brand name replacement filters. They arrived promptly during our recent wildfire season and helped make our indoor air more breathable

I’ve got my Blue air 600 for years, this year when time to replace its filter I was told to wait until next month. Just I couldn’t wait and decide to search Amazon. I am so lucky to buy it with fast delivery and great price from Amazon.

These filters have been an acceptable replacement for Blueair originals in the past, but now the filter portion is smaller, product is the same overall size but cardboard covers almost half an inch of the actual filter all the way around on front and back.
