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 oil Who sells someone something that’s already defective.

Quality, authentic

Great filter, works perfect with my Blueair device.

Good quality

良し悪しを述べるべくもなく【純正品】を買うに限ります(通算10回目5年の使用) 今まで自宅でハウスダストのせいか、鼻炎に悩まされていましたがブルーエアクラシックを使用してからそういった事案はほとんどありません。 昔はイオンも飛ばす加湿空気空気清浄機を使ってました。 湿気の嫌な臭いもさることながら、鼻炎も改善されず、空気清浄機能だけに特価したブルーエアを導入。 上記の通り鼻炎の改善は本当に驚きました。 もっと驚いたのは、フィルター交換時に排気側がほとんど汚れていない事。 吸気側は仕方ないにしても、本当に濾過してるんだなという関心と掃除の手軽さはすごいです。 互換品は使ったことが無いので比較しようがありませんが、 確かな性能を求めて同社の純正品を買ったのであって、不確定なものに投資は出来ないかなと。 難点を上げるとしたらフィルターが割高に感じる事でしょうか。 半年手放しにはしないにしても手間はほぼ皆無だし、フィルター交換だけで済む手軽さと性能を買っていると捉えれば安くはないけどコスパは良いと思います。 他の人にも進められるいい商品です。

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.

I have had allergies for years, shots on two arms every spring. And after years of suffering, my brother told me about Bluair and I got it. This thing is short of miracle. The Bluair series is great. It filters air, odors etc. And from the time I have gotten the Bluair and the filter, I have had limited or no pollen issues. It sucks the air and filters air so well. The filter is by other comparative standards, on the expensive side, but it really lasts. And you can see how black it gets. One filter lasted more than 6 months plus longer. But for health, reducing my allergies, removing odors...can't beat it. I love this thing. It is by far the best investment I made. No complaints.

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)
