BLUEAIR DustMagnet 5400 Series ComboFilter, Genuine Replacement Filter for DustMagnet 5440i, 5410i Home Air Purifiers for Dust, Virus, Bacteria, Smoke and Allergies

Original filter from Blueair

Fit my Blueair DustMagnet 540i perfectly. I still had 5% left on the old filter, but wow, it was black.

Brand name replacement, brand name price. But you get what you pay for, and my indoor allergies are 95% gone using a few BlueAirs around the home. I'll pay a couple hundred a year to have much less sneezing! I can also say with confidence that there is way less dust. I still run a swiffer around my surfaces one a week or so, but I can use a whole cloth per floor of my home (about 600 sq. ft per level) instead of needing multiple.

Don’t compromise with the quality of the air you breathe. Blueair filters are superior in every way.

Good product, efficient air cleaner

I purchased the Purifier roughly 8 months ago. I did a lot of research because it was not cheap, and neither are the filter replacements. The researched paid off. I am a smoker, and have smokers in my home from time to time. This purifier is a beast and the filters are amazing. I wish I would have purchased it earlier. I was going to get off brand filters but they were not much cheaper, and these were still going strong after 8 months, the app said they were at 16% but I could tell around the 6 month mark they were starting to not do as good of a job. The Blueair is a Winner, and I will probably buy another for my office. The filters are heavy duty and the whole product is better than I could have imagined. Kudos to the designers and manufacturers.
