How often should I clean the cartridge?

Most pool owners clean the cartridge every 4–6 weeks, depending on bather load, weather conditions, and debris levels.

How long will this filter cartridge last?

Typically 12–24 months with proper cleaning and balanced pool chemistry.

Can I use this in a saltwater pool?
