This air purifier from Amazon is the real deal. It’s mostly been running in auto mode, and it reacts fast when the air gets worse.
What I liked
- Touch buttons with modes like night mode and auto
- Air quality light and number. Red is poor, then yellow, then green with a single-digit number when it’s running normally.
- Fast response. I’d been grilling and opened the door, some smoke came in, and it immediately picked it up, ramped up the fan, and started purifying.
- Essential oil cup on the side, so it also works as a diffuser
A bonus: an AC filter check
I have a timer to change my AC filter every few months. But I noticed that as the filter got close to needing a change, the purifier wasn’t sitting in green as much. It was spending a lot of time in the yellow range. I checked the AC filter, it was dirty, I replaced it, and the purifier went right back to staying green.
Things to know
I haven’t messed with the other modes a whole lot, because it’s just been running in auto.
Specs from the Amazon listing
These come from the Amazon listing title. I didn’t test them myself:
- KNKA APH4000 air purifier
- Listed for rooms up to 1,695 sq ft in 1 hr
- White
Bottom line
It works well, and it doubles as an extra check on your AC filter.
Price and availability change on Amazon, so check the listing for current details.
