Great Selection -- Fair Price

Even though my furnace takes a standard size filter, there are multiple dimensions that fall within that "standard." Filter King made it easy to find the exact size I need, and at a reasonable price.

THE RIGHT SIZE!

Showed up earlier than estimated, in good condition. Unlike many others I've purchased from elsewhere, these are the correct size, the size that is listed on the item description. Glad I found Filter King, and planning to purchase again in the future.

So far so good

Company shipped promptly and the box was in great shape. I immediately placed one in my furnace, slid in very well, the slightly smaller size as notated made installion easy. Furnace has been running for 2 week. It's doing the job.

Incredible Experience To Share

My AC guy told me the wrong filter size to order. It is a custom size so I figured I would have to "eat it", but I contacted Filter King anyway. Without hesitation they sent me shipping label to send it back then made the correct size and sent it to me at no additional charge. This is a wonderful company so you can buy without hesitation.
