   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 Classic 400 Series Genuine Particle Replacement Filter stands as a testament to the enduring quality and efficiency that the brand is known for. It’s a classic choice for those who own compatible models, delivering effective air purification that users have come to expect from BLUEAIR. However, it’s worth noting that these filters come at a higher price compared to the newer generation filters available in the market. This cost factor is something to consider, especially for regular users who require frequent replacements. While the performance is top-notch, the price point is a significant factor, especially when newer, more affordable options are available.

   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.

   I use these 400 series filters on my BlueAir Classic 405, and I haven’t had any problems. Whenever it’s time to install a new filter, the old one has a lot of dust and other particles on it. It’s especially visible when you compare the old filter next to the new one that you’re going to replace it with.

   We have two cats and a nephew that is severely allergic to them. Bought this unit a couple of years ago to make the house bearable – when he would visit, within an hour his eyes would start watering, nose would get stuffy, and he was miserable.

   The first time we used the air cleaner we did so for one day in one of the main rooms and the next in another, and upon our nephew’s next visit he was fine the whole day!

   Let me add that our house is very allergy friendly – there are no carpets, no drapes, both of which are great for holding in the stuff that people with allergies react to.

   This is a great unit and the filters, while expensive, are well worth it.

   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.

   Was happy to find this filter sold at blueairoutlet.com. I have owned a Blueair 402 air purifier for over six years and it has been a great purchase. Even though the machine and filters are expensive, they are well worth the investment. I run my machine 24/7 during months when pollen is heavy. In the summer, I run it 24/7 to help keep my bedroom cool and it is wonderful to sleep in cool, CLEAN air. That’s six years of constant use and have never had to do any repair…just replace the filter a couple of times year.
   I have recommended the Blueair 400 series to my friends and those who have purchased it have always thanked me as it works great for them too.

   Haven’t used my BlueAir in a while. Have an older unit. Concerned about reviews talking about odor. Opened package and airing out just in case. Otherwise, looking forward to using my BlueAir 402 again.

    Blueair recommends changing the filters for their air purifiers every six months.

    The entire system is not inexpensive because the purifier is expensive and the replacement filters seem relatively expensive.

    However, the performance is valuable for anyone with allergies. By the time my filters are changed, there is noticeable build-up of particles so I know that this is something that we would be breathing in if not for the purifier.

    When I think about what our purifier does, running 24 hours a day, 7 days a week, for 365 days a year, I am appreciative for our cleaner air and decreases allergy reactions. The cost of the filter, changed twice a year, is approximately $0.45/day. For me, and my family, this is a good deal!

    This is an excellent product. Easy to install and perfectly does its work. A gave three stars because of TERRIBLE DELIVERY, This a second time, I am receiving filters with damages, in damaged original manufacturer’s box. Personally, I decided to buy this filter in the future somewhere else.

    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.
