We have been using Blue Air for over a decade and have been happy with them. Have the 411, the pure fan, and our first one the 400. Had a couple fan issues over the years but customer service has been good so far.
Blue air junk? I have been using blue air for a decade and got one for each of my staff conference rooms during the COVID response - none of us got sick and we were in person for over a year. These things have been running for years daily and I’m a fan…
I live in Southern California, and the filters are great for fire season to keep the air clean inside. They also help when other things are going on outside like skunks, kicked up dust, the neighbors’ smoky fire pits, or even when it’s a bad pollen day. I’ve tried various brands and I still like the Coway AirMega 200M (same as the AP-1512HH). It’s not the quietest at higher speeds, and it’s not tiny, but it moves the air and filters very well. There’s a reason it’s long been the top pick of Wirecutter. If you want some more style, the various BlueAir models, especially the Pure line are very nice and also work well. They’re a bit expensive though. If money is no object, Austin Air makes some highly regarded machines. In general, UV and ozone are gimmicks. The biggest thing to look at are the CADR ratings. Higher numbers are good, they mean the unit is delivering more filtered air quicker. Always check replacement filter prices, often a good deal on a machine means they make money on selling filters.
Blueair works okay. It’s expensive but does work. Coway is definitely more performance for the money though.
I have a giant blue air and I love it. Before we didn't have one in a smaller space and I feel some days I was dying. The cost of the filters is kind of pricy though.
Large Blueair running 24/7/365 for years now. Own 2 large dogs and it definitely makes for an improvement in air quality
We have Blue Air - a large one in the main living area, which catches kitchen/cooking particulate, and a mini one in each kid room. Costco has two packs of the minis for $99 right now!
I second Levoit, we have almost one in each room. And we also have a Blueair large room. Both are a smart device connected and man the amount of dust the pull is scary.
