Understanding Hot Tub Filtration and Circulation

Hot Tub Filtration System:

The filtration system in a hot tub plays a critical role in maintaining clean and clear water. It passes water through a filter that traps dirt, debris, and other contaminants. There are three main types of filters used in hot tubs: cartridge filters, sand filters, and diatomaceous earth (DE) filters. Cartridge filters are the most common and consist of a pleated fabric that catches particles as water flows through.

Sand filters use a bed of sand to filter out impurities, while DE filters use a fine powder made from fossilized diatoms to capture even the smallest particles. Each type has its own advantages and maintenance requirements, but all serve the essential purpose of keeping your hot tub water clean.

Water Circulation:

Proper water circulation is just as important as filtration in maintaining a clean hot tub. Good circulation ensures that water is evenly distributed, which helps prevent stagnant areas where bacteria and algae can grow. Circulation pumps and jets work together to keep water moving continuously, pushing it through the filters and ensuring that chemicals are evenly distributed. This keeps the water clean and enhances the soaking experience by maintaining a consistent temperature and providing a gentle, soothing massage. Regularly checking and maintaining the circulation system is key to ensuring your hot tub’s overall water maintenance effectiveness.
