Mineral Systems
Mineral pool systems use minerals like silver and copper to sanitize your pool. The minerals are slowly released into the water, where they kill bacteria and other microorganisms.
Pros
- Like saltwater pools, mineral pools are often reported to be gentler on the skin and eyes than chlorinated pools.
- Mineral systems can reduce the amount of chlorine needed to keep your pool clean.
Cons
- While mineral systems can kill many types of bacteria, they may not be as effective against all types of algae and bacteria. You may still need to use a small amount of chlorine or another type of sanitizer.
- The metals used in mineral systems can cause staining on the pool surfaces if the levels are not properly managed.
As you can see, there’s no one-size-fits-all solution for chlorine alternatives for pools. Each system has its unique benefits and potential drawbacks. Your choice will depend on your specific needs, budget, and personal preferences.
Whether you opt for a saltwater system, a UV system, an ozone system, or a mineral system, you’re taking a step towards a healthier and more enjoyable swimming experience.

Other Alternatives to Chlorine You Can Also Consider
Lowering Water Temperature:
By decreasing your pool’s water temperature below its usual level, you can inhibit bacteria and algae growth. These microorganisms typically flourish in warm to hot conditions. Cooler temperatures also slow chemical reactions, including those involving human skin.
While this isn’t a standalone solution, it can certainly lessen the amount of chlorine needed. However, swimming in colder water might be uncomfortable for some. The method you choose to cool your water largely depends on the weather.
For warm climates, a pool chiller might be suitable. In colder weather, aeration or oxygenation via fountains could work. If you have a water heater, lower the thermostat. Keep in mind, heaters and chillers can be costly compared to other pool equipment. Despite the reduced chlorine usage, the expense might not be justifiable.
PHMB:
Certain brands, like Baquacil and Softswim, have introduced Polyhexamethylenebiguanide (PHMB) as an effective alternative to chlorine. PHMB is more stable than chlorine and isn’t affected by sunlight, eliminating the need for a stabilizer.
It’s also gentler on the eyes and skin and doesn’t corrode pool surfaces. However, PHMB is pricier than chlorine, and maintaining a PHMB pool can be costly. You might also need hydrogen peroxide as an oxidizer and monthly pool filter cleanings.
If you’re switching to PHMB, it’s advisable to drain any water containing traces of chlorine. Also, ensure that your skin or swimsuit is free of chlorine before swimming to avoid reactions with PHMB.
Bromine:
Bromine is an alternative to chlorine (often used in hot tubs), although it shares similar properties due to being a halogenic compound. Despite fulfilling the same roles as chlorine, bromine is not a widely preferred option due to its higher cost.
Like chlorine, bromine must be used alongside other chemicals and additives. Stabilizing bromine can be challenging and doesn’t perform well in outdoor pools. Therefore, while bromine is an alternative, it may not be the most practical or cost-effective choice for all pool owners.
Ultrafiltration:
Ultrafiltration involves using a fine sieve to remove tiny microbes, skin particles, hair, and more after basic filtering. Apart from the minimal amount of chlorine needed, this filter removes all other suspended particles, organic matter, and bacteria.
The system includes filter tubes with thin membranes circulating water at low pressure. These membranes have semi-permeable pores that allow essential disinfectants and certain salts to permeate back into the pool, purifying the water without chemicals.
However, this technology is currently too expensive for most applications. Over time, advancements and increased production should reduce the cost of these systems.
Pristine Blue:
Pristine Blue is a unique technology created by Earth Science Laboratories. The primary ingredient is copper sulfate pentahydrate, making up to 19.8% of its active components.
This technology leverages the power of positively charged copper ions to annihilate negatively charged bacteria and other pool contaminants. While highly effective, it’s important to note that Pristine Blue is among the more expensive options for maintaining a swimming pool.
Copper Ionization:
Regarded as one of the best alternatives to date, copper ionization offers an effective solution for a chlorine-free pool. This method doesn’t leave residual chemicals that can irritate the eyes and skin. It’s a cost-effective choice that results in healthy pool water.
A copper ionization system includes an electronic control unit, test kits, and a copper electrode. The ionization process releases metallic ions into the water using a low voltage current. These positively-charged copper ions are attracted to negatively-charged bacteria and algae, penetrating their cell membranes.
As the water recirculates, more ions are produced. Copper ions are unaffected by sunlight, eliminating the need for a stabilizer. Unlike chlorine and salt systems, ionizers are pH neutral, simplifying pH maintenance. These systems are easy to install, maintain, and can be retrofitted to your existing chlorinated pool.
