Smilyan 3 Pack Blue Pure 411 Replacement Filters for Blueair Blue Pure 411 411+ 411 Auto and Mini Air Purifier

Love this product!Blue airs replacement filters are way too expensive so I saw these on Amazon and tried them out. (You get 3 of these filters for like the price of 1 from blue air that has no noticeable difference.Since then, I’ve bought these twice.They have no smell, they’re well packaged, clean, and fit in my 411 perfectly. They last about a month each filter.It’s a great value filter replacement, would recommend!

The filters came in a smallish box which is easy to put away until you need them. But then I forgot where I put them! I'll be more careful next time. Installation is a piece of cake and they do their job absorbing all the crud in the air.

Huge difference in effectiveness between low and middle speed with middle much better for both dust and odor removal.Hint: once in a while, take the fan top off and vacuum the outside of the cloth filter sleeve without removing it from the tube.

They are slightly larger than the oem, but you can't tell once the cover is on. Also the charcoal layer is a bit thinner. All in all for the price a good deal, but not as good as oem

Works

Just like the one I purchased with my purifier. They fit perfectly and the machine continues to run just as before.

Fits as it should.

I have a subscription for these filters that fit my Blue Air machine. I change filters every 2 months, so a package lasts 6 months. It is much cheaper than the name brand and they seem identical. When I change the filter I am always amazed at the amount of dirt it collects. I receive an email before the product ships so I can make any changes to the order. I also receive shipping updates. If they have the type of filters you need, I would not hesitate to recommend Smilyan.
