Genuine 311 Auto Air Purifier Replacement Filter, Everyday

I order this every year! Great product, keeps my air pure and clean

With three dogs running around the house, the Blueair 311 Auto replacement filter has definitely earned its keep! Between the dog hair, dust, and whatever mystery smells they bring inside, this filter helps keep the air smelling much fresher. It’s easy to replace and gives me peace of mind knowing the dogs and I are breathing cleaner air. If you have dogs, this is one of those things you don’t realize you need until you see what comes out of the old filter!

These are the real deal, expensive sure but I change the filter every 6 months and these are the ones I get. They do their job (and I have 2 dogs) I will not say its an easy replacement because anybody that has that model knows how snug the filter fits (and then that cover but thats another story) But I'm not disappointed with the filter at all aside I wished they weren't so expensive.

I have three cats and I am semi-allergic so an air purifier is a must! These replacements are genuine and very easily to install. You just take off the fabric wrapping the slide off the old filter and replace with the new one. This really helps with odor removal. This brand is great!

Easy to install and the filter help keeps the air in my home clean. The machine Is not real loud when it turns on to clean the air.

I love my BLUEAIR Blue Pure 311 Auto air purifier, and while the replacement filters are a bit pricey, they are worth it. When I change them, I can see all the stuff they collected, which makes it easier to accept the cost. The filters do an excellent job of keeping the air clean. Highly recommend for anyone using this air purifier!

Excelente producto muy recomendable y viene rapidísimo en el mismo días funciona muy bien el aire de mi casa es apropiado para mi bebé de 4 meses había mucho polvo volando por todas partes

I read some reviews here that this filter was too large or didn’t fit, so was a bit wary. I have a Blueair Blue Pure 311 Auto which it fits perfectly on. Blueair it seems has a tendency to name their air filters very similarly, so just make sure to double-check your exact model. The filter itself makes a difference in air quality so I felt it was important to purchase a genuine one versus a cheaper one. My filter is never very dirty after 6 months so sometimes I use a filter for a few months past that timeframe – I just reset the light and put a calendar reminder for myself to change it a couple months later. All in all, great product.

Works well no issues

Quite easy to install and worked beautifully.

Not bad

Product arrived as expected and description and authenticity is as described. I will order again. Blue air as really good reviews and surpasses many other brands that cost twice it’s size. I have one in each room but different models and so far so good. I have bad allergies and this helps me out a lot and also helps by reducing dust.

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!
