Great service and delivery

The price is good but the delivery not so good I have to call 3 times to get it

Fast delivery and a very decent price!

Excellent

I waited for more than a week, but the service was good.

Buying was nice and easy, fast shipping ang good looking filters. while the package was intact, some filters were a bit bent, actually one have a broken side, but with some attention I am sure will make it work.

Ordered custom furnace filters and received on time and as ordered. They promptly answered questions. Still a better price than stores.

To long for the delivery

Item received as ordered. Quick delivery and good pricing.

I’m very happy with this service and the shipping time and the quality of the product. We have a geothermal furnace and it requires a unique size filter and United was able to find something that suits our needs

Great price as well

Great service!

Thanks

Nice to have a supplier who is prompt and on time. Knows your order. And a call desk who is professional

Amazing service, I get my Furnace filter from them for the last 2 or 3 years and they always sent me the right size. In my case fitres are different than standard dimensions. Good Job guys
