They read my mind and then some when they made these filters-lots of surface area, easy on the hardware and full filtration.

Great Filters

I checked each of the filters and they look good. The only thing I wish included is tabs that combine opened up at the ends to make it easier when pulling a filter out. Otherwise the filters look great.
