Is Chlorine-Free Treatment Better Than Chlorine?

The answer depends on what you want to achieve.
Below is an objective comparison:

 Advantages Compared to Chlorine

✔ No chlorine smell

No classic “pool chlorine” odour.

✔ Much gentler on skin and eyes

Excellent for people with sensitive skin, dermatitis or allergies to chloramines.

✔ No volatile gases

Chlorine becomes aggressive in hot water, while oxygen-based sanitizers remain mild.

✔ Does not bleach swimwear or dry skin

A less aggressive oxidizer.

✔ No chloramines

Avoids the irritation and smell caused by chloramine formation.

Best suited for private spas with lower bather loads.

 Disadvantages Compared to Chlorine

❌ No long-lasting residual protection

Chlorine (and bromine) stays active in the water.
Chlorine-free sanitizers work only at the moment of dosing.

➡ Often requires an additional sanitizer (e.g., bromine tablets).

❌ Less effective against strong contaminants

Oxygen-based systems may be insufficient for:

• biofilm

• heavy bather loads

• strong bacterial contamination

❌ Not ideal for many users at once

If 4–6 people use the spa the same evening, chlorine or bromine works better.

❌ Requires more frequent water testing

pH, oxidant level and additional sanitizing agents must be monitored.

Summary: Is It Better?

✔ Better if you want:

• softer water feel

• no smell

• minimal skin/eye irritation

• a more natural water experience

• light to moderate spa usage (1–2 people)

❌ Worse if you need:

• strong disinfection

• high bather load

• very stable sanitizing protection

• maximum hygiene performance

Technically:

• Chlorine-free systems win in comfort, mildness and water feel.

• Chlorine/bromine win in strength, stability and protection.

Usage Instructions

Add the recommended dose according to your spa’s water volume.
Ensure proper circulation after dosing and test water regularly to maintain balanced sanitation levels.
