Overview Keep your Watkins Hot Spring spa water silky-smooth and crystal clear with the Poolzilla PWK35B replacement filter cartridge — a precision-built drop-in designed specifically for Watkins hot tub systems. Measuring 14 1/8 inches tall with a 6 3/8-inch outer diameter and a 1 15/16-inch center hole, this cartridge is sized to fit your Watkins filter canister exactly the way the original did, with no shimming, adapters, or guesswork required. The deep, evenly spaced pleats dramatically expand the dirt-trapping surface area, catching body oils, lotions, hair, and the fine particles that cloud spa water and clog jets. Sturdy molded end caps create a leak-proof seal so every drop of water passes through the media — not around it — giving you cleaner water, easier maintenance, and the kind of clarity that makes stepping into the hot tub a treat. Spa filters work overtime because hot water, jets, and bather oils put extra demand on the filtration media, so plan to rinse your PWK35B every two to four weeks and replace it every three to four months with regular use (or every six months for lighter, seasonal soaking). When you notice cloudy water that won't clear after shocking, weaker jet pressure, or your spa working harder than usual to heat and circulate, that's your cue to swap in a fresh cartridge. A clean filter protects your pump, helps your sanitizer do its job, and keeps the water genuinely safe for the people you love. Order your Poolzilla PWK35B today — and consider grabbing a spare so you always have a fresh cartridge ready when soak time calls. What's Included Your order includes the selected quantity of replacement spa filter cartridges. Each unit is individually inspected for quality before shipping.
