    Best Air Purifier

    This is probably the easiest item I have ever setup. Just remove from the box, take out the filter and unwrap, put filter back in place. We have other air purifiers and this is my new favorite. First, I really like the design. The rectangular design seems to flow the air better than in the round models. The air is pulled in from the rear, cleaned and then put out through the sides. Air movement is excellent on speeds 2-4 and okay on speed 1. Even on Max (4) it does not sound really loud. Auto is probably the best setting for daily use as it will increase the fan speed if needed. The display on the top of the unit is easy to understand. Air Quality, Mode and Filter life are shown in a large display. I burned some bacon in the oven and 10 seconds after I opened the oven door it was purifying the air on max. The unit is about 18 feet away from the oven. When my husband came home he never knew there had been a bacon incident. Our construction is still going on so I have been moving the unit to other areas of the house. It has performed excellent and cleared the dusty haze. This is the one to buy. NOTE: I received this product in exchange for my fair and unbiased review.

    Disappointed. Several key issues. OEM filter are way overpriced. Luckily they can be found half price elsewhere. No child lock… this air purifier is my son favorite toy now… how hard is it to add a child lock option. Started the unit, air quality at 60% machine ran in auto for 24h air quality still at 60% in a room about 600sqft… For the price you should have a Bluetooth option to connect to your phone with a dedicated app to see the data.
