The major chlorine shortage in 2021 forced many pool owners to consider alternative means of purifying their pools and keeping bacteria at bay. A popular option today is UV purification, one of the relatively newer technologies in pool cleaning. 

Clark County Pool & Lawn’s staff was asked by our clients about chlorine alternatives last year. The chlorine shortage has since eased, and we continue providing residential pool services in Las Vegas this summer. However, interest in other options, including UV purification, hasn’t wanted.

How it Works

By understanding how UV purification works, you may determine whether or not it’s suitable for your pool. Note that it’s not a completely chemical-free system. UV sanitation systems will still require some chemicals, but not the same amount as a standard pool treatment.

When an ultraviolet light system is installed in a pool, the water that flows through its filtration system passes through UV light. This targets and destroys bacteria, germs, algae, and other microorganisms.


Safe for swimmers

With substantially less or no chlorine in the UV pool system, it’s a safer environment for swimmers who are sensitive to chlorine. There is also less chance of red eyes and skin irritation as there aren’t as many chemicals used. 

Advanced system

The UV purification system is considered one of the most advanced pieces of pool equipment in the market today. It’s a high-tech solution to a fundamental problem, and you can be sure that you’re getting safe, effective equipment that does the job.

Low maintenance

Because fewer chemicals are involved, and the water passes through UV light, you won’t need to do as much maintenance to keep a pool clean and the water clear. You also won’t need to stock up on pool shock chemicals.

The technology is still new, so expect a UV system to be expensive. Prices range from $350 to $2,000 for residential pool systems. However, you will still get the convenience and benefits if you choose to go with a midrange system.

Another cost to factor in is electricity. Powering a UV system-filtered pool will cost more because it will have to run for hours to purify the whole pool. How long will depend on the size of the pool and its water capacity. 

Installation can also be expensive. You’ll need a professional to install this type of system for you, and that will be an added fee.

Only as effective as its reach

The only areas that the UV light can clean are areas it reaches. So if all of the water doesn’t pass through the light, some bacteria may remain in the pool. 

Less effective over time

As with any piece of tech, it gets worn out with time. You’ll have to keep replacing the light in the system to keep it effective, and this will be an added cost.

Consult a pool maintenance specialist

If you’re still unsure whether the UV system is suitable for your pool or your needs, consult a pool care specialist who can provide you with an analysis. They will provide you with information on the suitability of the system for your pool or if you’re better off sticking to the tried-and-tested pool shock method of purification.
