Our readers have great things to say about this air purifier…

I have a different model of Winix at home in the bedroom and in my work office. Costco sells them — and also sells multi-packs of the replacement filters! I’ve had my Winix units for years, and I really love them. It runs quietly in the background.

They have an air quality sensor that “knows” when to turn the filter up to “high” — it’s hilarious when a dog is lying next to it farts and causes the sensor light to turn red and the air filter to kick into high mode! LOL

I have this exact model – purchased from Costco during the pandemic. I HIGHLY recommend it! It is literally on my nightstand and I can barely hear it. I love the sensor in it – like the person above commented, when my dogs come around, the sensor kicks it into high! LOL
