5400 Series H13 Filter Set Compatible with BLUE®AIR 5410i, 5440i DustMagnet Air Purifiers 5400 Series, 3-Stage Filtration High-efficiency Activated carbon 2-IN-1

A breath of fresh air at a great price. The world may get more and more hostile but my house is a respite of clean peaceful (filtered) air

Yes it fits my Blueair and seems very good. Price is competitive. Would purchase again when the time comes.

Works great in our blueair filter. Installation was quick. Just had to pop open the back slide the old one out and slide in the new one. Just be aware of the way the filter is facing. Filter seems to work. Its hard to say for sure.

Overall good value when compared to the OEM filters. While I have no way to really test these filters they seem to do a good job. Their construction looks good and they fit perfectly. There are no functionality issues. I am not sure they have as much carbon as the OEM filters but at half the price I am okay if they do not as I use the unit mainly for dust control. Make sure to install them with the black carbon side inwards towards the center of the unit.By the way, to reset the filter life counter on your Dust magnet press and hold the fan button on the unit for about 15 seconds. There does not seem to be a way to reset it through the app.
