Cost Effective Efficient Filter
I have been using this filter for my Trane high efficiency heat pump for a little over two years now. It filters out a lot of dust all the while keeping a good air flow. I change the filter about every three months but may go to every two months as I live in an area that has its fair share of dust. The only negatives are that the wires are thin causing you to be careful when putting these on the frame and the other is having to put these on the frame. Yes, I would love to simply pull out the used filter and slide in a new one, but the cost of doing that is more than I want to spend. It takes me around 5 minutes to put the new filter on the frame as I don't rush the process for fear of not putting it on right. I highly recommend these filters.
