About Hot Tub Filters

When looking into your hot tub's health, you should be considerate about the filter you use. The filter takes in dirty and contaminated water from the spa and cleans it before it back into the spa. Please make sure the water used in the spa is clean such that it should not contain any debris or harmful materials.

1. Hot Tub Cartridge Filters

Cartridge filters cost more, and they are more efficient. They should be maintained regularly as compared to sand filters. The filter has a plastic cylinder, and a polyester filter has been put in place. The water will flow from one end, and small particles (at least 10 micros) are captured. The clean water then gets back into the sap. The filter's lifespan is three years, and it lasts depending on the amount of work it does.

The filter requires to be cleaned regularly, which means you should remove it physically and rinse it for it to operate effectively. Also, these filters should be sprayed using filter cleaner. The chemical ensures the filter is clean, and it operates efficiently.

When operating a sand filter, make sure you are good at chemistry. Since such filters are less effective than the rest, they capture large particles, which means the spa's chemical composition should be well balanced to ensure the smaller particles in the water won't pose a significant issue.


3. Dematiaceous Filters

This filter is expensive as compared to the other two listed above. Despite being expensive, it guarantees value for your money such that it ensures the water is extremely clean. The filter can get rid of particles as small as 5 microns. Rest assured that the water you use in the hot tub is safe and clean with such a filter.

The hot tub filter is efficient since it has an internal grid covered with white powder made from aquatic organisms that effectively filter and clean the water. The powder also helps to get rid of pests that usually invade the water. The filter lasts for two to three years.

Regardless of the hot tub filter you are using, regular cleaning and care are paramount.
