A spa filter ball is a type of filter media used in water treatment for spas and hot tubs.
It is a small, spherical ball made of durable, chemical-resistant material such as polyester, which can filter out particles and impurities from the water.
Spa filter balls can replace traditional filter cartridges and sand filters, offering some benefits such as easy cleaning and maintenance.
They are also said to have better filtration efficiency than some other types of filters.
To use spa filter balls, they are typically placed in the filter compartment of the spa or hot tub.
As the water passes through them, they capture dirt, debris, and other particles, leaving the water cleaner and clearer.
The balls can be cleaned and reused multiple times before they need to be replaced.
