Hot tub filters are essential for maintaining clean water in a hot tub.

They trap particles as water runs through the filter media and act as the primary line of defense against dirty spa water.

Most hot tub filters today are designed as cartridges that can be easily removed, cleaned, and replaced.

Each cartridge consists of a core structure, usually plastic, and a medium wrapped around the core that acts as the filter.

The medium is pleated, and the many resulting folds greatly increase the surface area of the filter for better cleaning action.

The most popular types of hot tub filters are cartridge filters, sand filters, and ceramic filters.
