All About Hot Tub Filters

Even if you purchase a hot tub with the most modern accessories, you still need to maintain it regularly to keep it from losing its functionality. One of the accessories that are most taken for granted in hot tub systems is its filtration mechanism. This should be specific to your budget, preference and time required for its maintenance.

Uses of hot tub filters

Keeping the hot tub clean is a must if you want to have a satisfying hot tub experience. This is also essential to prolong the life of your unit, as harmful bacteria can cause damage to your hot tub's surfaces and accessories. Hot tub filters help in getting rid of water algae and avoid the propagation of germs that can cause disease.

Kinds of hot tub filters

1. Sand filters -- This type of filter uses sand as the medium. The unclean water passes through layers of gravel and sand, which help in pulling out dirt, debris and other impurities. Water clarifier products such as Bright and Clean can also be used to congeal the microscopic particles and thus enable these larger particles to be effectively filtered before the water enters the tub. Change the sand at least once a year to ensure its filtering efficiency.

2. Cartridge filters -- Constructed with fine Dacron mesh, cartridge filters are the most common types of hot tub filters. Its efficiency lies in the pleated mesh -- the more compact the folds or pleats, the larger the surface working to catch debris or dirt in the water.

3. Diatomaceous earth filters -- The diatomaceous earth (DE) filters are made from crushed bones that are likened to sponges with lots of tiny spores. These petrified bones are coated on a grid of fresh mesh and act as glue, trapping minute dirt particles.

How to maintain your hot tub filter

* To ensure effective water circulation, the hot tub has to be run at least an hour daily. Put in a small amount of water clarifier and balance the water's pH at least once a week.

* Depending on the hot tub filter's size and the amount of accumulated debris, the cartridge filter needs to be replaced at least once a year. Check if there are cracks in the ends of the plastic or if the plastic fabric has been detached from the plastic.

* Never use chemicals that are not specifically designed for hot tub use. Soap-based cleaners can do more harm than good; also use oil-absorbing sponges that lessen the amount of oils that seep into the filter.

* Make it a point to shower just before dipping into the tub to keep cream, lotions, hair spray, gels and other hair care chemicals from clogging the hot tub filter. These can be harmful to the hot tub filter as most cannot be dissolved by water. In addition, maintain the right water chemistry and keep a spare hot tub filter for use when the other is being cleaned.
