Hot Tub Purification System

Before making a purchasing decision regarding systems for purifying hot tubs, consumers should first have an understanding of what these units are and why they are important. Like swimming pools, the water in hot tubs needs chemical sanitation products to prevent the water and the hot tub from breeding bacteria, germs and fungus. Pool owners constantly monitor their water quality and add chemicals to bring the pH in balance to prevent mold, algae and other toxic germs.

Purification systems can be built right into the hot tub unit, and reduce the need for many chemicals. This is beneficial to consumers who have allergies, as well as those who aren't comfortable using harsh chemicals regularly.

What options are available?

  1. Copper and Silver Ionizers: These devices deliver copper and silver ions into the hot tub's water in small measurements in order to kill off algae and bacteria. Chlorine still must be used in conjunction with this ionization method. In addition to that, non-chlorine or chlorine shock treatments must occur periodically in order to prevent organic contaminants from building up in the hot tub.

  2. Zinc Ionizer: If the hot tub's water already contains a high level of mineral content, zinc ionizers are highly recommended. This type of ionization is recommended for all hot tubs, in general, as well, because it allows for better filtration. In addition, zinc ionizer systems prevent the growth of algae, and helps extend the efficiency and the life of the hot tub.

    Space technology has found its way into spas and backyard technology. For around $330 you can purchase a Complete Spa Ionizer, designed to sterilize water for long-duration trips in space. When applied in hot tubs the system uses two silver-copper zinc alloy electrodes that generate ions when an electric current passes through killing bacteria and germs without chemicals. Using mineral purification for water is a process a millennia old that has been used for drinking, and for recreational use. This process is a healthy alternative to using chemicals to kill viruses and algae.

    The process of mineral ion purification is easy, and in most cases softer and gentler than a chemical treatment. You’ll be extending the life expectancy of your hot tub shell, bathing suits and towels, pumps and other equipment. Consider an ionizer a way to cut down the operating costs of you hot tub.

  3. Ozone: There are two different types of units available. One is called a CD, or corona discharge, ozone system and the other is a UV, or ultra-violet, ozone system. In the UV system, normal air is put through a UV light filter. This light takes the air molecules and splits them into separate particles. Oxygen molecules bond with other oxygen molecules because of this and when that happens. it creates ozone. This ozone takes out impurities in the water. The CD system works the same way except that instead of the UV light breaking air down into oxygen molecules, it is done with a gas.

    The Aqua Sun XL-80 Universal Ultra Long Life CD Ozone System with Injector 120/240V is one example which will cost around $135. There is no need to buy a separate Venturi injector or ozone mixer. The Aqua Sun XL-80 has a direct hook-up with an ozone injector attached to a 3/4" water line. Integral cavity mixing maximizes mass transfer (dissolving of ozone) for fewer ozone bubbles introduced into the spa water. Another product that will enhance your tub, and save you money while owning a hot tub.

    The consumer marketplace sees more sales with CD systems because they are more reliable. Consumers should be aware, though, that a chip must be replaced from time to time and the unit will lose output efficiency over time. There are a number of CD ozone systems available and each has their own design, so it's important for consumers to shop around to research which is best for their needs. UV systems are safer and usually will only require a lamp bulb replacement. These bulbs are pricey and need twice a year replacement at minimum. However, corona discharge systems need routine maintenance of its components. From a price standpoint, UV is less expensive than corona discharge.

Why should consumers shop around for purification systems?

The purchase of a hot tub is a long-term investment, and a costly addition to someone's home or business. In addition to regular maintenance and upkeep, the need for filtration and purification systems further add to costs experienced directly to the consumer. Therefore, it's best to weigh out all options carefully and don't buy from the first retail location visited. Explain to the service technician exactly what type of hot tub you have, what your budget is, and what your concerns are. If you are unhappy with the answers you receive, move on to the next retail location. Don't be afraid to visit a location more than once before making your investment.
