Review on 🐾 Winix HR900, 5-Stage True HEPA Filtration Air Purifier for Pets, 300 Sq. Ft, White by Caroline Saunders

Don't notice much difference in smell or air quality. I have several pets. There is a lot of pollen and I see yellow when I vacuum. I'm still sneezing He often goes to sleep. Goes into high mode with red randomly and infrequently for very short periods of time, less than a minute, and then goes back to sleep. Tried turbo mode and medium settings, no change. I don't see anything on the filters and I've had it for over a month now.
