The filter itself wasn't the normal white color that I expected but that didn't seem to affect its performance. Overall it still looks and performs like a typical filter. No issues at all!

They are too I would not take them back.

The filters were too big and FilterBuy would not let me exchange or refund them. I now have to cut all my filters to get them to fit or just throw them away. This was not a good solution.

Subscription Service is Amazing

I signed up for the subscription service last year. Right on time, the box came with enough filters for the next year. No digging for sizes or running around to a number of stores looking for the size I needed. Convenient. Cost effective. Made in the USA.
