Is Universal Cleaner safe for people with asthma?

Yes. Koh Universal Cleaner is approved under the Sensitive Choice program, run independently by the National Asthma Council of Australia. Sensitive Choice products are assessed as better options for people with asthma. The fragrance-free, low-fume formula avoids the airborne triggers (perfumes, harsh solvents, chlorine, ammonia, VOCs) that commonly set off asthma attacks in conventional cleaning products. The formula is just two ingredients: potassium hydroxide and reverse osmosis water. There are no fragrance compounds and no volatile organic compounds added to mask the cleaning chemistry.

✓ Sensitive Choice approved

Independently assessed by the National Asthma Council of Australia. No fragrance (a top asthma trigger), no harsh fumes, no chlorine, no bleach, no ammonia. Two ingredients only: potassium hydroxide and reverse osmosis water.

Is Universal Cleaner safe for people with allergies and eczema?

Yes. Koh Universal Cleaner is approved by Allergy UK (the UK's leading allergy charity) as a better choice for allergy sufferers, and is certified by the Eczema Association of Australasia (since October 2025) as suitable for eczema-prone households. The two-ingredient formula avoids the most common cleaning-product allergens: synthetic fragrances, preservatives such as parabens and methylisothiazolinone, dyes, and harsh surfactants. Good for skin allergies, hayfever triggered by fragrance, eczema, contact dermatitis, and chemical sensitivities. Always patch-test on a small skin area if you have a known reactive condition before extensive use.

✓ Allergy UK + Eczema Association certified

The simple formula avoids common allergens in cleaning products: synthetic fragrances, parabens, methylisothiazolinone, dyes, and harsh surfactants. A good choice for anyone with skin allergies, eczema, hayfever, or chemical sensitivities. Allergy UK certified and Eczema Association of Australasia certified.

No synthetic fragrance No parabens No dyes No harsh surfactants

How can I reduce trigger exposure while cleaning?

Even with a Sensitive Choice, Allergy UK, and Eczema Association certified cleaner, simple routines help minimise exposure for asthma, allergy, and eczema sufferers. Ventilate the room by opening a window or door for airflow. Where practical, ask someone else to clean heavily affected spaces (such as bedrooms) before you return. Wipe rather than over-spraying generously in small or enclosed rooms; spraying onto the cloth instead of the surface reduces airborne mist. Pair Koh Universal Cleaner with microfibre cloths, which trap dust, pollen, and dander rather than flicking them into the air. Wear gloves if you have known contact dermatitis. Keep windows or fans on for 10 to 15 minutes after finishing.

✓ Three-step low-trigger clean

1

Ventilate. Open a window or door. Good airflow helps disperse any trace airborne particles during and after cleaning.

2

Wipe instead of over-spraying. In small or enclosed rooms, spray onto the cloth rather than misting the surface generously.

3

Use microfibre cloths. They trap dust, pollen, and dander rather than flicking them into the air. Pair Universal Cleaner with Universal Cloths for best results.
