"Please accept this letter as an endorsement for the PERMANENT
We installed the FIBERLENE FILTERS in our home a year ago. Our
home requires five filter sizes.
Replacing them was a chore. However, shopping for them was a nightmare!! Now, we remove; hose; and replace!!
We have also noticed our units run for less time to maintain 72 degree. This cuts our utility cost.

We highly recommend the FIBERLENE FILTER. It's a winner!!!!!"
