Sold me a filter that was already written down as defective, and returned by a previous buyer.
Sold me a filter that was already written down as defective, and returned by a previous buyer. They even wrote the dates when it was bought and returned.I tried it and the smell was horrible, like a car that was leaking gasoline and oilWho sells someone something that’s already defective.

High Quality Air Filters
The Blueair filters are hospital grade filters that remove particulate down to about 1 micron. The filter with charcoal filters out unhealthy gasses. The Swedish designed Blueair Filter Units are excellent quality with noise levels below ambient bedtime levels (about 30 dbA)

Worth it
The best air purifier brand in the market. I have been using Blue Air Air cleaners for over 8 years. Eliminates dust, pollen or even food smell. Sneezing, hay fever and itchiness are gone as well, and my eyelid doesn't feel heavy. I am extremely tidy, but London's air quality is terrible. I would not recommend any other brand than Blue AIr. The filter is heavy on price but your lungs are worth more than that.

Hate the Price but as far as I’m concerned I think they’re Superior…
I hate paying so much for a filter as we have 3 of these units BUT I think it’s worth it to buy the genuine model. I’ve tried a couple of different knock-off brands and I just don’t think they work as well as they seem to mess up the auto function. One of my units continuously kept going back and forth between settings 2 & 3 and the only way to stop this was to turn off auto. This has not happened with the Blueair filter. When changing the knock-offs they also don’t seem to be as dirty as the Blueair brand for some reason plus the Blueair seems to slide in and fit better and are easier to remove. I'm not a germophobe or fanatic but my air just seems fresher.These new ones I just purchased have different instructions on the sides. Instead of saying “This side must face back or front” there’s just a sticker with an arrow indicating AIR FLOW DIRECTION. I pulled this sticker back and sure enough it covered the original side placement instructions. I’m really not sure if this is really clearer as it was a little confusing to me. However, looks like the metal side goes facing the intake and the corrugated side faces the control side. Seems to be working great and I think I’ll stick with the Blueair from now on. Don’t be alarmed by the slight oil odor when you first install as it seems to dissipate very quickly.
