Spa Filter - C4950 Unicel C-4950 Replacement- 4 Pack

SPA FILTERS - C-4950 - REPLACEMENT FILTER 50 SQ/ FT (4 PACK)

C-4950 replacement 50 sq ft filter - 4 Pack

Universal Fit for Waterway, Cal Spas, Bullfrog, and More

Crystal clear water starts with a quality filter. If your hot tub water is cloudy even after adding chemicals, your filter cartridge is likely clogged or worn out.

This 4-Pack Value Bundle ensures you have a year's supply of filtration on hand. These high-performance cartridges are designed to replace the industry-standard Unicel C-4950 and Pleatco PRB50-IN, offering superior flow rates and micro-particle trapping.

The "50 Sq. Ft." Advantage (Upgrade Your Filtration)

Many hot tubs come stock with a smaller 25 sq. ft. filter (Part # C-4326 or C-4625).

• The Upgrade: This C-4950 model has the exact same dimensions but contains double the pleat material (50 sq. ft.).

• The Benefit: More surface area means less resistance. Your pump doesn't have to work as hard to push water through, which increases flow at the jets, extends pump life, and allows the filter to go longer between cleanings.
