Fantastic Filters

These are great filters, made in USA, and always available in the exact size needed. I received them quickly after ordering and installed my first one immediately. I expect my cooling system to work more efficiently and aid in the reduction of my electric bill. I am always running behind with changing these out and now that I can receive them via mail order, I have much greater likelihood to stay on top of them being changed. Great job!!!

Work well- see a difference in less dusting! Real nice to see a discount- First time I saw one and told neighbors! Both of us purchased additional filters.

I have not used the filters yet as I am waiting until my last filter needs to be changed, but the buying process, cost, and the overall quality of the filters seem to be great!
