Blue Air Filter Specification
The Blue Air filters work very well and filter down to 1 micron. I have noticed that several marketers are selling knock offs which I doubt have the same filtering specs. It would be interesting to see the competition publish data.

new filter for treasured blue air classic
when I bought my Blue Air purifier classic 400 series many years ago for my NYC apt -it was the best decision, and I have benefitted ever since. I recently purchased a new dual protection filter for my treasured blue air classic and am happy to recognize the quality and dependability of the Blue air purifiers

Easy to use
I just inserted the new filter so I cannot tell you how great it is. However the filter I removed was quite dirty so it appears to be doing a really good job. Time will tell for sure. It’s very easy to change and just go about your day.
