Love the filters and how well they work. More than anything I love that I can buy the odd-shaped filter on filterbuy in bulk. It's saving me a huge amount of money.

I’ve been subscribing for a while now. This particular filter is in my bedroom and it visibly works well. I change mine every three months and appreciate the convenience.

I have been buying these filters for at least five years. I like that I can have them auto shipped to me. Highly recommend.

Thinking about furnace filters?

I don’t actually give much thought to furnace filters. I buy the size and the MERV the HVAC guy tells me to, and I don’t seem to have any air filtration problems, so I assume they’re working.
