Units are easy to setup. Didn't need to read the booklet but the attached illustrative diagram was very helpful. Takes time to be effective, I believe 2-4h at Max might not do it but again it depends on the size and the quality of air. When on the turbo setting, it's noisy. On Auto with occasional revving up is not bad at all from a nose stand point. Air fresh after about 2 weeks of running. Customer service is very responsive and helpful. I received 3 units with the downgraded filters and they immediately send me label to ship the filters back and FedEx the new ones. Over all very satisfied.
Got the one with 3lbs of charcoal and the only purifier I tried that actually cleans the wildfire smoke out of my house. Also very quiet, if not silent. I now have 2 of these!
We are really seeing an improvement in our quality of air in our home. We live in wildfire area and have had several fires too close for comfort. This has helped eliminate the heavy smoke from coming inside. We also have a fur dog, which one of us is allergic to- this helps. We also have oak trees hear which seem to bother several of us- this also helps with that. We highly recommend getting one of these for you home.
It has a sleek, contemporary design and was very easy to assemble and use. Delivery was very fast. I like the auto fan function and the ability to turn off the display. The fans are reasonably quiet. To be optimally effective, the unit should be placed in a smaller space than the maximum coverage listed. There is wildfire smoke here and It is a challenge for the purifier to maintain good air quality in my open concept living area. However, I like the unit and will purchase the 45i for my bedroom.
Works great and is very quiet for the amount of air it displaces. I have some trouble with the touch buttons not working officially l occasionally, as well as the sensor not being as good as I had hoped.
