Is Universal Cleaner safe for asthma and allergy sufferers?Updated 8 hours ago

TL;DR: Yes. Universal Cleaner is approved by the National Asthma Council of Australia's Sensitive Choice program and Allergy UK. The two-ingredient formula (potassium hydroxide and reverse osmosis water) is fragrance-free, phosphate-free, and paraben-free — none of the additives that commonly trigger asthma and allergic reactions.

Is Universal Cleaner safe for people with asthma?

Yes. Universal Cleaner is approved under the Sensitive Choice program, independently run 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, VOCs) that set off asthma attacks in conventional cleaning products.

Is Universal Cleaner safe for people with allergies?

Yes. Universal Cleaner is approved by Allergy UK (the UK's leading allergy charity) as a better choice for allergy sufferers. The two-ingredient formula avoids the most common cleaning-product allergens: synthetic fragrances, preservatives (parabens, methylisothiazolinone), dyes, and surfactants. Good for skin allergies, hayfever, eczema, and chemical sensitivities.

✓ Allergy UK approved

The simple formula avoids common allergens in cleaning products: synthetic fragrances, parabens, dyes, and harsh surfactants. Good choice for anyone with skin allergies, eczema, hayfever, or chemical sensitivities.

No synthetic fragrance No parabens No dyes No harsh surfactants

How can I reduce trigger exposure while cleaning?

Even with a Sensitive Choice and Allergy UK approved cleaner, there are simple routines that help minimise exposure for asthma and allergy sufferers. Ventilate the room (open a window). Where practical, ask someone else to clean heavily affected spaces like bedrooms before you return. Wipe rather than spray generously in small or enclosed rooms. And pair Universal Cleaner with microfibre cloths, which trap dust and allergens rather than kicking them into the air.

✓ 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 Koh microfibre cloths for best results.
