BLUEAIR 511 Replacement Filter - Air Purifier Filter - Activated Carbon - Black - For Blue Pure 511 Air Purifier

This filter is worth the money I paid for. It works great and definitely removes any orders. I have it in my bedroom and the room is not so small, but yet it gets the job done. The Air Purifier is so quiet.

Does what it needs to do. As a genuine product, it fits well in the air purifier.

.....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

Not sure if it is working for me, but wake up less congested :). Using in our bedroom. VERY quiet. Good product.

I LOVE my Blueair Blue Pure 411 and Blue Pure 511. They run so silently, clears odours quickly and leaves fresh clean air in its place. I bought extra filters so that I can change them up, every 6 months for the next few years as recommended. I love it so much I also bought the 411 version...one for me and one for my grandson.
