Review on Replacement Particle Activated Purifier Blueair by Vivian Eker

We've been using the Blue Pure filter in two houses in a row for over six months. The filter light eventually came on, so I bought it to replace. The old one had a lot of dust, we cleaned the pre-filter a couple of times but I'm still impressed with how long it's held up. The new one was pretty easy to put back on and run again. Had to check the manual on how to reset the device after replacing it, but after a few minutes it was working again. A little expensive, but worth it to protect the sleeping area from dust in the air.
