Great product
It's easy to sync to my phone, easy to access the filter, can see the percentage left on the filter. It has a display showing a number on the air purity. It works. I opened the door with a sandy wind blowing in and the number skyrocketed. Liked it so well we bought another one for upstairs.

Big HEPA filter with cool display and controller
This has a big HEPA filter and a great variable speed fan, but the control panel is worth the little extra price. It isn't necessary to be a great filter but the particle detector display coupled to the automatic fan speed feels like luxury. It is so cool the see the number climb and the fan kick up after my door opens and closes. It doesn't take long to clear the air. I can blow a puff of (non-billowing cloud) vape smoke at it from about 5 feet and watch the numbers climb. If high enough, the red lights come on and the fan speed increases.

Great purchase!
Very nice and quiet air purifier. I love the aromatherapy option too. Compact in size.
