UV vs. Saltwater Pool Filtration

I am sure in the past you

31 Jul 2019

I am sure in the past you have heard the debate between chlorine vs. saltwater pools – some of you may have had to choose for yourself. However, there is a new and, in our view, superior method for keeping your pool clean: UV also called Ozone. We have recently begun using BioShield, a UV sterilizer, in our newest builds, and we wanted to use this post to flush out the pros and cons of both UV and saltwater pools. In the end, it should be clear why we favor UV, and the massive benefits it can offer to both you and your pool.

First, what is a UV pool?

UV pools, and BioShield specifically, utilize an ultraviolet lamp to sterilize a pool’s water. The water filters through a tube with low temperature, energy conservative UV lamps that kill harmful bacteria and pathogens. BioShield is 99.9% effective at neutralizing bacteria and provides cleaner and safer water than most alternatives.

With this said, UV pools still contain some chlorine because a reliance on water circulation means chlorine provides a quicker bacterial remedy when needed. While this may sound off-putting, the chlorine levels are reduced by 50% or more, and even saltwater pools still contain chlorine. Even with low levels of chlorine, we believe UV offers the best solution for cleaning your pool, and we contrast the pros and cons to saltwater specifically below.

What are the pros and cons of saltwater and UV?

Saltwater Pools

Pros
Lower maintenance than chlorine pools, as salt levels remain relatively stable
Less irritation than chlorine pools
Cons
Still contains some chlorine
Greater up-front cost
Leaves white buildup on tiles
Corrosive to surfaces and equipment

Calcium build is up is 5 times worse on a saltwater pool vs a UV pool.

UV Pools

Pros
Very low maintenance
Instantly neutralizes bacteria
Less irritation than chlorine pools
Cons
Still contains some chlorine
Additional energy usage

 

We hope this comparison between UV and saltwater pools illustrated our reasoning for choosing UV, BioShield specifically, as our preferred method of cleaning pool water. The UV system is newer but gaining popularity quickly due to these obvious benefits, and we would not be surprised if everyone makes the switch to UV at some point in the future.
