Hayward C275S SwimClear 275 Sq Ft Single Element Cartridge Pool Filter, 2" x 2.5" Unions — Genuine OEM

The Hayward C275S SwimClear Single Element Cartridge Filter is a genuine OEM 275 sq ft cartridge filter for in-ground pools. It uses one large pleated cartridge to trap dirt without sand, DE or backwashing, and its low-head-loss design helps the pump work less so you can cut run time and energy use.

Built for Easy Servicing

The tank is glass-reinforced copolymer with an Easy-Lok ring that opens quickly for cartridge cleaning, comfort-grip handles for lifting, a recessed pressure gauge and a manual air relief valve. The low body height also makes it easier to lift the element out.

Frequently Asked Questions

What size pool is this filter for?

At 275 sq ft with a 100 GPM design flow rate, the C275S suits larger residential in-ground pools. Match the flow rate of your pump to the filter before ordering.

Do I need to backwash it?

No. This is a cartridge filter. You remove the cartridge and rinse it off instead of backwashing, and no sand or DE is needed.

Does it include the cartridge?

Yes. The C275S is a complete filter with one cartridge element installed. For future replacements, look up the C275 cartridge element by part number.

What plumbing does it connect to?

The tank uses 2 in x 2.5 in union connections and has a 1.5 in drain port.

Can I use it with a saltwater pool?

The tank is built from glass-reinforced copolymer, which does not rust. Check Hayward's documentation for the use you have in mind.

Who should install it?

A qualified pool professional is recommended. Turn off and isolate the pump before opening the filter, and relieve pressure with the air relief valve first.
