“I tested it with kitchen odors while cooking, and within about 20 minutes of running the air purifier, I could smell little to nothing. I find that astonishing. I've used other air purifiers before, but this one does the trick.”

There are lots of options, and great info in the app, but literally, turn it on, and let it do the work. Air is noticeably cleaner, amd most smells are squashed (I have it on top of the cat litter box)

This is one of the best, smartest and quite air purification units I have ever had. It literally detects everything and purifies everything immediately. So quite that you could keep it right next to your bed. Add the wooden leg base and it makes a perfect bedside table/nightstand.
- LLBMBVerified Reviewer2 days agoReviewingBlue Signature™ Medium MidnightRated 5 out of 5 starsBy Far The Best Air Purifier I've Ever Owned
I have had quite a few air purifiers but this one has been the best one yet. I have used it in my room with our cat litter box. Even with 2 cats, you can't smell our litter box at all when this purifier is in the room. I have also moved it when I have been cooking. This little machine easily removes all cooking smells. It cut down the smells so much that the next day, not everything that was in the same room smelled like fried onions. One of the things I love about this is that it is so easy to move. So, even after avweekend of wrestling tournaments, I can move this into my laundry room and rhe smelly teenager/sports gear smell is gone! Well worth every penny!
- SSeanVerified Buyer1 week agoReviewingBlue Signature™ Large MidnightRated 5 out of 5 starsThis air purifier saved my family's home from a potential house fire!
In early Feb 2026, while we were sleeping at 2am our Blue Signature purifier in our bedroom went to the highest setting while on auto mode. This woke my husband up, so I checked my app to see what the air quality was and it was very poor. As I started to doze back to sleep, I started to smell smoke. When I opened my door it immediately smelled like burning wood. I went downstairs to find smoke coming out of our gas furnace. The air purifier detected the smoke before our fire alarms would have went off. When the fire department arrived they later told us another 30 minutes to an hour later the walls could have caught fire and potentially burned down our house. We later moved the air purifier into a main space and it helped remove the smell of smoke that lingered in our home over the next few days.
We have had this air purifier for several months and it does a great job. My family does a lot of home cooking and it really helps remove the smell of food odor that lingers in our bedroom. The purifier is also great at removing dust from the air, which was another reason for why we purchased it. I have and will continue recommend this purifier to others!!

Small but powerful unit. It just works, really nothing else to say. All my air purifiers are Blue Aire. I have not tried anyone else and just being don't see a need to try anyone else. No gimmicks, no smoke filled chambers, these work. I owned 10 of them. Enough said.
