Hot tub filters keep your spa water free of debris and dirt. They have an essential role in reducing the risk of hot tub system damage and providing a pleasant breathing experience.
Most hot tub owners know the importance of using chlorine or bromine to keep the water clean, but what about filters? How often do they need cleaning? Do you need to replace them when they have deteriorated?
In this article, we explore the world of jacuzzi filters. We discuss filter types, how to clean them, and how and where to find an appropriate replacement.
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.
Jacuzzi filters remove a part of the bacteria from the water, but you still need to use chlorine or bromine for a regular spa to prevent green or cloudy water. This is important, especially if the spa water has an unpleasant odor.
It is not enough even if you use chlorine to sanitize your hot tub. Dirt and debris are not dissolved by sanitizers.
While some filters are able to trap some types of bacteria, others filter chemical contaminants.
Even though filters don’t remove all bacteria from hot tub water, O-Care provides a solution for using up to 78% less chlorine and bromine. Our product helps you reduce the use of hot tub chemicals and to help your filter live longer.
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.
