About This Item
The Unicel 4CH-935 is a 4000 Series 35 sq. ft. replacement filter cartridge precision-engineered for Waterway Teleweir Skim Filters and compatible hot tub systems. With 219 pleats of 3 oz. Reemay 2033 polyester media, this cartridge delivers exceptional dirt-holding capacity and long service life — keeping water cleaner between cleanings and extending time between replacements.
⚠️ IMPORTANT: Master Spas Eco-Pur Owners — Verify Overall Length Before Ordering
This filter is compatible with Master Spas Eco-Pur filtration systems using a 5" OD cartridge. However, Master Spas uses multiple filter lengths across models. Measure your existing cartridge's overall length (top to bottom) and confirm it is 9 1/4" before ordering to ensure correct fit.
