Best Swimming Pool Water Sanitation Systems

Achieve clean, healthy pool water with less chlorine using pool water sanitation systems from Hayward, Nature2, PoolRx, Zodiac, Balboa Water Group, Clear Comfort, and International Leisure Products. PST Pool Supplies stocks salt chlorine generators, UV sanitizers, advanced oxidation process (AOP) systems, and mineral purifiers for inground and above-ground pools, starting from $25.

The sanitation systems in this collection represent four categories of alternative and supplemental pool treatment technology: Salt/Ozone integration — the SALT3 Integrated Salt/Ozone System combines saltwater chlorination and ozone generation in a single unit, providing dual-oxidizer sanitation with a dramatically reduced chemical demand. UV sanitation — the Paramount Ultra UV 120V 2-Lamp Sanitizer and Balboa Water Group Wavetec254 UV System use germicidal ultraviolet light (254nm) to destroy bacteria, viruses, and chlorine-resistant pathogens (Cryptosporidium, Giardia) that chlorine alone cannot reliably kill; the Nuvo UV Above-Ground System (15K gallons) brings UV sanitation to above-ground pools. Mineral purification — the Nature2 Inground and Above-Ground Express Systems (Zodiac) release controlled amounts of silver and copper ions that kill bacteria and algae, allowing pools to run at chlorine levels as low as 0.5 ppm; the PoolRx Blue Unit (mineral purifier) and PoolRx+ Black Unit (20K–30K gallon) use chelated copper and zinc minerals for algae prevention and chlorine reduction. Advanced Oxidation Process (AOP) — the Clear Comfort CCW100 AOP System combines UV and hydrogen peroxide to create hydroxyl radicals, the most powerful oxidizers available in pool treatment, capable of destroying contaminants that UV or ozone alone cannot. For ozone-specific systems, see our pool ozonators collection.

Modern pool sanitation philosophy has moved decisively toward supplemental systems that reduce chlorine dependency rather than eliminating it entirely. UV systems destroy pathogens in the return line with no residual chemical in the pool; mineral systems provide a persistent low-level algaecide that dramatically reduces the chlorine needed to prevent algae; AOP systems handle the heaviest oxidation loads. The practical result in all cases is a pool that maintains water quality at 0.5–1.0 ppm free chlorine rather than the 1–3 ppm typically needed without supplemental sanitation — meaning less chemical smell, less skin and eye irritation, lower ongoing chemical costs, and cleaner-feeling water. When selecting a system, match the rated pool volume to your actual water volume, and verify that the system's installation requirements (flow rate, plumbing bypass, UV chamber orientation) are compatible with your equipment pad layout.

Shop pool sanitation systems and upgrade your pool to a cleaner, lower-chlorine water treatment approach.
