UV Pool Sanitizer System: Pros, Cons & How Does Work?

We all know that one of the most important parts of owning an inground pool is keeping it clean. Slacking on maintenance can damage your pool and let’s face it, no one wants to see their sparkling oasis turn into a swamp. Luckily, you have a few options when it comes to keeping your pool clean.

So how do you keep the pool water clear of bacteria and parasites?

One effective solution is to use an UV pool sanitizer system, which uses ultraviolet light for pool sanitation. These systems don’t involve pumping lots of chemicals into your pool, and some say they are superior to the “old fashioned” sanitation method of using chlorine.

We’re giving you the lowdown on UV pool systems to introduce you to new ways of sanitizing your swimming pool. Let’s start with the basics…

UV Pool Sanitizer Review

What is an Ultraviolet (UV) Pool Sanitizer?

Ultraviolet (UV) pool sanitizers utilize a cutting-edge, non-chemical process that uses germicidal UV light rays to sanitize water, air and surfaces that may be contaminated. Ultraviolet pool sanitizers emit a high intensity germicidal light ray that alters or disrupts the DNA or RNA of targeted organisms such as algae, bacteria, viruses, cysts and protozoa. The highly concentrated electromagnetic energy also destroys organic matter, eliminating the formation of dangerous chlorine by-products.

How Does UV Pool Sanitizer Work?

UV pool system is installed in-line just after your pools existing filtration system. UV pool bombards the passing water flow with a high intensity germicidal ultraviolet ray that destroys more than 60 waterborne pathogens, including algae, bacteria, cysts, and viruses. The UV sanitizing lamp is housed in an industrial graphite housing optimized for high flow rates. A highly specialized quartz glass sleeve protects the lamp from passing water while transmitting 99.9% of the UV light. The highly concentrated electromagnetic energy destroys organic matter and eliminates the formation of dangerous chlorine by-products called chloramines that commonly lead to red, stinging eyes, skin irritations, asthma and allergies. This energy penetrates the cell walls of bacteria, viruses, algae, cysts and all pathogens. That’s right: no pathogen can escape a powerful dose of UV from a UV sterilizer system.

Are UV Sanitizers Safe?

Ultraviolet sanitizers are very safe. The ultraviolet lamps are housed in a rugged high-impact polymer housing. UV cannot leave or escape the sterilization chamber, so UV never enters the swimming pool. UV is a physical process rather than a chemical process, making UV the most environmentally friendly choice in pool sanitation. There is no residual effect that is harmful to humans, animals, aquatic life, plant life or the environment. UV also minimizes the need to generate, handle, transport, or store dangerous chemicals.

How Much Do UV Pool Systems Cost?

A UV system could cost as little as $200 to well over $1,000 to install, where saltwater systems are $1,000-$2,500 and chlorine systems are under $100.

This option will reduce the need for chemicals and algaecides, will not cause dry skin or itchy eyes and can save homeowners up to $600 on chemical expenses annually. It will not deteriorate pool equipment. And the only maintenance required will be an annual cleaning and lamp replacement.

Pros

  • Ensures the pool is clear of harmful parasites
  • Requires fewer chemicals
  • Can be affordable, depending on the brand
  • May be safer than chemicals alone
  • Considered by some as the best form of cleaning technology
  • Low maintenance

With all of these benefits, UV pool systems still aren’t foolproof. Here are some of the not so great things about them that you need to know about.

Cons

  • Sanitation only happens while the water is under the UV light. If the light misses some of the bacteria, it can get back into the pool.
  • You need to sanitize the piping where the water goes back into the pool, which involves using chemical cleaners.
  • The UV light becomes less effective over time, so you’ll need to replace it regularly to keep the pool clean.

Keep in mind that It’s also important to monitor and balance the pH levels in your pool, since these can affect your pool’s filtration system. That said, most of the issues you might have with UV pool sanitizer can be prevented with proper routine maintenance.
