Smilyan3 Pack Blue Pure 411 Replacement Filters for Blueair Blue Pure 411 411+ 411 Auto and Mini Air Purifier

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

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.

Works

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

Fits as it should.

Seem to work as well as the brand name for fraction of the cost

I will start by saying 10 out of 10 would definitely buy again. I have three of these in my house. Prior to having these I have had six other types of air cleaners all ranging in price. All of the others much more expensive than these with filters much more expensive than the replacements for these. This unit does a great job. The replacement filters for this unit are well priced, easy to use and the unit is very user-friendly. If you are not set on high you cannot even hear the unit. I prefer it set on high because I like the white noise. I like the interchangeable covers this is a household staple for us. You can’t beat the price or the durability or the longevity of this unit. I have had these three units running in my house and replaced the filters easily. I live on a very tight budget as a single mom with two cats and three dogs. This filter works overtime in my house and still does an excellent job. 10 out of 10, would buy again!

This is the third air cleaner product from this manufacturer which we have; living in a downtown area where the air is really dirty. I love this unit and these filters, even though they require some attention to detail to install. Regardless, they are wonderful products and it's great to have such effective and reasonably priced products like these available. Thanks!
