Great. I use my unit continuously.

I have a Winex air purifier AND I have pet rabbits and a cat. My house can get full of hair and dander. These thin pre-filters work very well and capture so much before it actually enters the machine. I always us these. Yes, I do recommend.

We have a brand new unit and first time using so I can’t say how well it works. But so far we had our unit 2 days it’s really nice product. I like that the pet filters come in a package of 12.

The red circles under my eyes are gone. I ✨️ love ❤️ my air purifier so much, I ordered an other . And a humidifier. So many days inside this winter
