Hot Tub Filters - What Are They?

Spa filters are essential components of hot tub filtration systems. Their role is to purify the spa water by keeping dirt and debris away. As a result, the hot tub's lifespan is extended, preventing a decrease in performance.

Filters remove a part of the bacteria from the water, but you still need to use chlorine[1] or bromine for a regular spa to prevent green or cloudy water. This is important, especially if the spa water has an unpleasant odor.

How do hot tub filter work: 

Hot tub filtration systems work using one of two types of mechanisms: suction and pressure. Suction systems are the most common among hot tub owners, even though they are a bit larger. Regular maintenance is required, but it's easier compared to pressure systems.

The pump pushes the water into the filter and allows it to recirculate. By repeating this process throughout the day, the filtration system is what keeps your water free of impurities.

Spa filters trap impurities and don't allow them to go back into your spa water or into the pipes.
