Product Description

For both new pool and aftermarket installations SwimClear™ single element cartridge filters capture more dirt for superior water clarity without the need of supplemental media or backwashing, while the industry’s lowest head loss reduces energy costs.  SwimClear™ is also the easiest to service: the Easy-Lok™ ring design, comfort grip handles, and lowest lift height provide fast cleaning and element replacement.

  • Industry-leading hydraulic efficiency allows the pump to run at a lower speed or for less time, increasing energy savings
  • Easy-Lok™ ring design allows quick access to internal components for quick and simple maintenance
  • Recessed pressure gauge and manual air relief enables user to place head assembly upside down on pool pad, protecting the seal from contamination
  • 2” x 2 1/2” union connections make installation and servicing fast and easy

I have +/- 10,000 gallons inground oval swimming pool. And I need a new filter. Could you advise me if the Hayward 100 will be ok my pool size. Thank you.

Hi, Joe. This Hayward Cartridge Filter - C100S will be sufficient for your pool if your pump flow rate does not exceed 100 GPM. To determine your pumps' flow rate, use our How to Size a Pool Pump guide.

Would 50-60 GPM to little flow for this filter?

A  Answered on 6/7/2016 by InyoPools Product Specialist Lennox H.

Hi, A flow rate of 50-60 gpm would be great for this filter. When the actual flow rate is lower to the max filter's flow rate the filter will perform better and last longer.

Hi Wayne, This unit will work good but the C150S will work better.It is always better to go one size up from when getting a filter.

A C100S Single Element Filter was installed in place of DE filter system. The C100S has no plumbing or valves to accommodate backflushing the tank or pumping down the pool water level in case of rain over flow. Is there something on this unit that I am not aware of -- in Florida it is imperative to have a way to pump down the pool in case of heavy rainfall.

On this model filter there is a drain plug on the bottom side of the unit that you can remove and add a water spicket to. You can then attach a water hose to that and extend that out to where you would like to drain the water.
