Love the pte filters because you can wash them, great idea. I would love some other colors, like pink, burgundy or Lilac

If you have a Blueair air purifier, you must get at least one back up fabric filter. I have a 511i Max and 211iMax and they filter the air so well that you need to change the filter while the other is being washed and dried. I purchase 2 extra of each size as well as extra particle filters to save time and money.

- ABAbigail B.Verified Buyer6 days agoRated 1 out of 5 starsSand color shows blue filter underneath!
I originally had a white filter with a gray pre-filter, which looked great. When I upgraded to a blue allergen filter and purchased a 'sand' colored pre-filter to switch things up - I was disappointed to see that the blue filter shows through the pinkish sand color pre-filter! I don't like the way it looks. I tried to ask customer service what color pre-filter might cover up the blue color better, but they weren't much help. I don't want to pay for the navy blue special edition - it's expensive - and all of the other colors look pretty light as well. I wish there had been some kind of heads-up on the product page for the allergen filter that some colors of the pre-filter were not recommended.

Quality made prefilter that traps larger particles such as dog hair.

The color is perfect for the room. I actually can now see the dust on the filter.
