How a Pool UV Light system Works, the Cost, Pros and Cons

May 13, 2021

One of the most vital facets of pool maintenance is keeping it clean. Turn a blind eye on proper care—and you can ruin your inground pool.

But let’s be honest, although chlorine is a safe sanitizer that keeps your pool water clean, overusing it can adversely impact your pool surfaces.

So, how can you keep the water clear of bacteria and reduce the overuse of chlorine? One reliable solution is using a pool UV light system.

How Does a Pool UV Light System Work?

This system is installed in-line just after your swimming pool’s existing filtration system. The UV light bombards the water as it flows through graphite housing, destroying waterborne pathogens, including bacteria, cysts, algae, and viruses.

That’s right; no pathogen can withstand a potent UV light dose since the highly concentrated electromagnetic energy eliminates the formation of chloramines. These are chlorine by-products that generally lead to skin irritations, allergies, and red, stinging eyes.

Pool owners with this system also use chlorine or bromine, but even then, at a much less concentration than those only relying on chemicals. Remember, proper cleaning of your pool weekly helps reduce chemical consumption.

But is using UV light safe? Well, this light doesn’t leave the graphite chamber, making it a secure way to clean your pool water.

This smart approach means users can successfully avoid adverse exposure to the light. Almost the whole process occurs within the UV system itself, and to make it even better, the setup doesn’t require much maintenance.

How Much Do UV Light Systems Cost?

The cost of UV pool systems varies. You can get them for as much as $3000 and as little as $1200. On average, if you’re looking for a pool UV light system that will get the job done right and last for decades, expect to pay nothing less than $2000.

Since each brand is different, always look into each system’s features before you purchase one. That way, you’ll have an idea of how different options differ and what makes them tick. Some of the common factors that affect the cost are:

Size of the bulb
Amount of water the system will be handling per minute.

Keep in mind that these prices strictly apply to residential pools. For systems designed specifically for industrial pools, you’re looking at costs of anywhere between $50,000 to $100,000.

Pros & Cons of Using Pool UV Light Systems

Like any other maintenance method, a pool UV light system isn’t without its share of drawbacks. You can tell whether this option is the best for you by looking at its pros and cons.

Pros

Requires fewer chemicals.
Low maintenance
Affordable, depending on the brand.
Much safer than using chemicals alone.

Cons

Needs regular replacement as it becomes less effective over time.
Sanitation only occurs when the pool water is under UV light. This means that if the light fails to hit some pathogens, they can get back into your swimming pool.
You’ll have to sanitize the pipes through which the water flows back into the pool. This involves using chemical cleaners.
