I have used these filters in our prior home and love the quality and price. I returned to purchase filters for the same filters in my new home.

Was unable to buy filters of the size, buying directly now solved the problem at a significant cost savings.

Product is significantly undersized and does not seal well at all in my trane filter housing. Would not recommend.
