Customer Reviews
Smooth order, good quality filters
I ordered a few 2 inch MERV 8 air filters for my home. The website was easy to navigate, and I found the right size without any hassle. Shipping was free, which was a plus, and the filters arrived in about 5 days. They were packaged well, no damage. I put one in, and it fit snugly. My old filter was really dirty, so this was a welcome change. I also contacted customer service once about changing my shipping address before it went out, and they responded pretty quickly and got it handled. Overall, a solid experience.
Good filter, fast shipping
Got a MERV 11 air filter. It arrived quick, took only 3 days to get here. Fit perfectly in my furnace. Happy with the purchase.
Got my furnace filters
Needed some new furnace filters, you know, just for regular maintenance. Found these guys online. Ordered a couple of 1 inch MERV 8 filters. They showed up pretty fast, like four or five days. They fit in the furnace fine, and everything seems good. Easy enough to get what I needed.
Great value on whole house filters
I was looking for a deal on whole house air filters and found Filterbuy. I signed up for their subscription and got a nice discount right away. The free shipping helped too. I felt like I got a really good price compared to what I'd usually pay at a local store. It was definitely worth it for the savings.
Finally found my size!
My furnace needs such a weird size filter, I always struggle to find them! Filterbuy had custom size air filters, and it was so easy to order. They arrived fast and fit like a glove. I'm so happy I found this place! I'll definitely be back for more filters when these run out!
Decent filters, some shipping delay
I bought a 4 inch MERV 13 air filter. The filter itself seems well-made and sturdy, comparable to what I usually get. The pricing was competitive, especially since they offer free shipping. However, it took almost a week for my order to ship out, which was a bit longer than I expected given their usual shipping times. Once it shipped, delivery was quick. Customer service was polite when I inquired about the delay. Overall satisfied, but a faster dispatch would make it even better.

What's the deal with shipping times? I'm in California and my current filter is kinda shot. Need a new one fast, like within a week if possible.
Hey, wondering if anyone's bought custom size filters from here? My furnace is old and has a weird size, so I need something specific. Did they actually fit right?
