Hi. I have a Hayward DE4820 filter and 1.5 hp pump. What size cartridge filter would replace the DE4820 filter? Thanks!
The Hayward cartridge filter that is the same size is the SwimClear 425 model W3C4030. That is a quad-cartridge filter. Click Here to View More Details on the Hayward SwimClear 425
We also have a single cartridge system that handles up to 60,000 gallons. The Waterway model PCCF-200 is a 200 square foot single cartridge filter. This would have to be cleaned out more often than a quad-cartridge system. Click Here to View More Details on the Waterway PCCF-200
