Silent air purifier. Easy to clean and replace filter. Good app, I'd just recommend turning off air quality notifications as those can be common during cooking.

Update- since my last review I've bought another filter specifically for this model and made by Philips. This time I noticed right from the moment I put the filter in that the red "broom" icon, which means it's time to clean/replace the filter, is already glowing red. Right out of the packaging! Although it appeared to be a brand new filter ( sealed, etc) apparently, at 0 minutes old, it's already showing it needs to be cleaned/replaced. No recourse because Philips doesn't have a customer service phone number, and their "contact agent" is AI and is unable "to compute" this issue.Since the device doesn't pair with the app I have no way of knowing what the icons mean or how to interpret the numbers. There is a red icon that sort of looks like a dust broom (??), no way to know what it means. I vacuumed the filter just in case, though the device was less than a week old ( with no excess dust or anything like it in my house to account for a "broom") but it hasn't gone away, and it's been red for a couple of months now. No phone number to call other than to make a purchase. Nowhere can I find access to a printed manual.
