Pleased and preparing
Although I am using just one unit now because I live in the Colorado mountain air. The other 2 are in case we have the predicted wildfires this summer.

Fast at clearing the air
Quite often smoke of various kinds works its way through the wall separating us from our neighbour. This filter seems to clear it from our air quite quickly, even at relatively low fan speeds.

Works great at trapping the smoke and other particles
Our Blueair air purifier has been great. I recently changed the filter and it is definitely pulling stuff out of the air because it was dirty compared to the new filter. We have two air purifiers and they work great to take our smells, smoke and dust from the air.

311i+Smokeblock filter
Quiet, smooth, effective, plus uncomplicated interface: all promises fulfilled and happy to have the device.
However, registration process to extend warranty was cumbersome and with uncertain success.

After burn oder from enclosed gas insert fireplace.
We bought your Blue Air Purifier because we have noticed an after burn oder from our enclosed gas insert fireplace. The filter has helped but occasionally the order is still noticeable. We usually set the Blue Air on its either the middle or next to highest level. The highest level is a little bit noisy.
