Genuine Filter for Blue Pure 511 Air Purifier

Simple and quick to install. To maintain a consistent high quality filtration and the cleanest air for my family, I only use the official branded replacement filter. No cheap Chinese imitation with inferior performance.

Highly recommend. The air purifier's noise level is non-existent, you can't even tell it's on. It really keeps the air clean and any funky smells out of a dorm room. The size is perfect for a dorm room. And the price point is fantastic. Ships fast.

Everything intact & sealed on arrival. Even though a resale item you would not have been able to tell the difference from a new item. Fit perfectly. No odor. Performing as expected

Came in a flat box which freaked me out, but it formed perfectly to the round shape of the device.

Good filter but on the expensive side for replacements

I do have a Blue Air filter and this is what I use to replace the dirty filters. I love it! I felt the price is worth it. It definitely purifies the air and works well with my Blue Air purifier. No weird smells and it lasts super long !

My other air purifiers have much more expensive filters. This price is right. The setup is easy and everything fits as it should. I especially appreciated the packaging not being too heavy and wasteful. One weird thing was that this package was lost in the mail for several weeks. When it realized it never arrived, I checked the app for context and found a vague order update that it “might have been lost...” To get a replacement, I had to agree that if the other (lost) filter ever did arrive, I’d drive it to a return center. It feels wild to me to have to take action and responsibility for returning a package that dropped of their radar…but alas. I’m guessing it’s never coming. Delivery snafu aside, it’s a great product. Will keep ordering.

Fits and works perfectly.

Love the filter and helps with odor smell. Highly recommend

.....when you walk through the air cleaner isles of the major supply stores....out jumps the same old same old Brands.....you may have tried many of them as I have.....Blue Air made in Sweden has helped me breathe well in times of smoke from forest fires....dusty winds entering through windows....normal household living...inadequate air cleaning done by your furnace etc.... ....I have 3 different models....small room.....medium square footage to large square footage....when you remove the outer fabric...and wash the pre-filter as instructed....change your inner filter as indicated by the units warning light....get ready for having these units around for a long time... ...quite is the big sell....don’t go with a small unit if you want your bedroom to have the ultimate good air....big mistake as a small unit on low just doesn’t make sense....medium sized or larger on low is silent but it moves more air..... .....the big sell is the units fan head on top the unit....years of use on my units....clean as a whistle to date...why...nothing gets through...other named Brand units get filthy after 6 months ....BLUE AIR simply the best....Tina Turner

Works great we smoke and it cleans the smell up

I am hoping that I do not have to use this for at least 6 months. So it arrived on time. yesterday, package was new and it arrived before I got the air purifier itself which just arrived this afternoon. Being that it is the manufacturer product, I would assume it will fit no problem and it really all depends on how well the air purifier I just received works. If the air purifier does not seem to be doing its job then I obviously will be returning both packages together. If need be will update in a week or so. I simply ordered this to have on hand when the need to replace the filter arises.

Perfect size for a bedroom. Very quiet. Looks great as well.
