The Comfort Zone is excited to announce that we now sell Pleatco Dual Core filters. The filters use two filtration medias, the outer layer working as a pre-filter to catch the largest particles, and the inner layer trapping particles down to 3 microns. The Pleatco filter cleans water to the highest level possible. Check it out at www.Pleatco.com or bring in your filter measurements to our store at 4408 China Creek Rd in Port Alberni. The best part of having a hot tub is having a hot tub with the cleanest water possible!
