Fits perfectly, just like the Lennox filter. It was less money than the Lennox. It arrived in a very short time.

These filters are a perfect fit for my Carrier system. I'm a repeat customer and have found Discount Filters easy to work with and very efficient. They are knowledgeable of the products they sell and can answer all questions.

It works BUT I love the new design that is in its own container open and just slide in the compartment. SO MUCH easier and faster.
