BLUEAIR Blue Pure 311 Auto Genuine Replacement Filter, Particle and Activated Carbon, fits Blue Pure 311 Auto Air Purifier

Very easy to install. Removes odors and dust. Love this machine.

I tried to save a little money and buy an off-brand filter…it didn’t fit properly and was a piece of crap. These blue air brand filters are amazing as well as the machines themselves! Had the air purifier for about 3 years. I replace the filter every 6 months and this is the difference when I go to replace it.

Removing and replacing this filter was very simple. It was delivered fast & the price was right.

Fits my BluAir 311 perfectly just as advertised. Very easy to install and packaged very well. I'll definitely be ordering again.

This filter works well with the product, as you would expect. It definitely filters out the stuff because when I replaced my first, it was filthy. The installation process was pretty easy but the instructions help quite a bit.

This is a fine filter for the air purifier. However, be aware that the 311 is not the same as the 311i Max, and the filter sizes are different. I made the mistake of ordering the wrong one and spent quite a long time trying unsuccessfully to make it fit. Once I returned this filter and ordered the correct one, it slid on like a hand in glove.

Perfect fit for my levoit air purifier. Installs as if it was the manufacturer’s one

I love these purifiers & filters. It runs so quietly and kicks on higher when I’m burning candles or if the windows are open and there’s a high allergy count. The filters seem to last for a long time, too.

Good price, good product, easy installation

Easy replacement and works great

I used this in our blue air pure 311 auto. This original One lasts alot longer and provides better filtration than the aftermarket thinner badly fitting ones. I would highly recommend just sticking with these ones and you will not have any issues!

What more is there to say :)

Easy to replace
