I have ordered 2 of these. I use one upstairs and one downstairs. I can tell a big difference in the air quality.
Exactly as advertised
Can program right from my phone, so quiet I forget it's on, had to start using the timer
I was very pleased with this purchase not only is it purifying the air in my daughters room, it is extremely quiet! It was well worth the money
I can tell it works because I tested normal air and then sprayed air freshener near it and it went into red which is bad air quality so I like it and believe it’s doing a good job 🤞
