FAQ

How do I find the right cartridge?

Read the model on the filter tank or the part number molded on the cartridge end cap. Length, diameter and end-cap style also help if the number is worn off.

Do you sell chlorine or other chemicals?

This category is cartridges and baskets. Some chemicals have shipping limits. If you need a chemical, tell us the type and quantity and we will say whether we can quote it.

How often should a cartridge be replaced?

Follow the filter maker's guidance and your water conditions. Cleaning extends life; a torn or collapsed cartridge should be replaced.
