Pat R Montevallo , AL April 21, 2020 The filter had not been changed in quite some time, so it was time!! My son changed the filter and did it so fast I didn’t even know that he had started to change it. I didn’t. My son did. It was just a matter of removing the old filter and putting in the new one.
