Review on 🌪️ Enhance Performance with WHIRLPOOL Filtration Replacement WHKF GD05 Packaging by Russell Wong

I installed a hot tub water softener 4 years ago and put (2) whole house filters in front of it. I use a WHKF-GD05 filter element as a first line of defense with a <1 micron hot tub carbon filter between it and the softener. I've started using pleated (paper) filters and have read that these filters work better when the media flows towards the center (not just the surface) through the entire filter. They last longer than paper before experiencing depressurization, although I rarely let mine last that long (I change them every 4 months). They've always worked for me, so I have no reason to change them.
