Great Product, quiet, gets rid of dust in the house, smoke and doesn't use much electricity. Also the WiFi control and the information it gives you is great. I liked it so much I ended up buying two more.
Since purchase i run it on high 24/7 , helps considerably with allergies and a few months ago when we had lots of smoke coming down from the Canada forest fires, this filtered all the smoke out. I dont use the app or blue tooth, I just turn it on high and run it, I vacuum the filter about every 3 months and change filter about every 6 months .
The Blue Pure works very well. I wish that there was more flexibility in how to order a replacement filter, and from what source. That keeps me from giving the product five stars.
