I’m happy with these guys. It comes when it’s supposed to, they’ve made changes to the packaging to make it more robust over the years, I’d recommend.

Perfect fit. Cleans the air

Perfect fit. Cleans the air better than my other filters, a lot less dust!!!!
The cardboard framing bends from the power of the air flow and it was slightly deformed and difficult to remove. Just a slightly thick frame will take care of this.

Furnace filters

I think they do a great job. We live in the high step desert and it can get very dusty. Especially when the wind blows. Keep up the good work.
Thanks
