Customer Reviews:
Blue Air Filters
The air purifier and the filters used in it have helped my daughter remain free of congestion. The purifier covers her entire apartment. When she wakes in the morning she is no longer has the congestion in her lungs that she had before she began to use the Blue Air machine and filters. She is able to breathe much easier. She lives in California. Having pure air to breathe while she is in her apartment has made a huge difference in her health and wellbeing. I don't give praise easy.

Out of date picture
I ordered the Blueair filters from the Recording Store, and they were not shipped until 5 days after the order was placed which resulted in longer shipping time than from other retailers. They were genuine Blueair filters and arrived in good shape.

With regard to others complaints about not having the charcoal filter, that's true, but after visiting the Blueair web site, it looks like Blueair has changed their manufacturing process and now include active carbon in the polypropylene portion of the filter.
