Pool and Hot Tub Spa Filter Cleaning Tips


How do I know when a filter needs to be replaced?

Typically, a filter cartridge is plugged up by perspiration and body oils combined with soaps and chemicals, very fine particles, and algae. These three factors will help you to know when it is time to replace the filter cartridge.

1. Shorter Cycle Between Cleanings
2. Low Water Flow Rate and High Pressure
3. Obvious damage to the filter media or center core collapse

These 3 factors depend upon proper pool or spa water chemistry and routine maintenance schedules.

How do I maximize the life of my filter?

1. Clean the elements based on your manufacturer's instructions
2. NEVER use a stiff brush to clean the filter media
3. Maintain proper water chemistry balance
4. Clean your filter regularly using steps below

For swimming pools, clean the cartridge when your filter canister reaches 8 PSI above the initial system or starting pressure.
