AqFresh™ & Oderase™

Advanced Pollutant Capture

What is it?

AqFresh™ is a revolutionary new pollutant capture technology for liquids, that helps safely remove indoor air pollutants including BTEX (benzene, toluene, ethylbenzene and xylenes), chlorinated compounds (in common cleaning agents) and formaldehyde. Cucurbit[n]urils can bind sulphur oxides (SOx) and nitrogen oxides (NOx) too.

It is also an odour capture technology for liquids, plastics and films. It is so effective that it works without the need for artificial fragrances to mask malodours.

Why is it needed?

Despite air scrubbing and carbon capture, many industries are still polluting the air. But indoor air pollution is just as important since many VOCs are considered hazardous to human health. Globally, 9 out of 10 people breathe air containing high levels of pollutants.(1) Nearly half of UK homes have high indoor air pollution as a result of dangerous levels of formaldehyde and other pollutants.(2)

75% of Brits are concerned about indoor air quality & want a spray that removes toxic pollutants. 65% are aware of carbon monoxide but only 34% have heard of formaldehyde.(3)

Why is it unique?

This patented technology consists of cucurbiturils – barrel-shaped molecules that powerfully capture pollutants to remove them.

AqFresh™ contains a mixture of cucurbit[n]urils (n =6, 7, 8) and each homologue has affinity for a variety of molecules. Thus, AqFresh™ has exceptional capability to bind a wide spectrum of molecules with different sizes and functional groups.

Cucurbiturils have a hydrophobic cavity and a polar portal that enables high affinity binding by releasing high-energy water contained inside the cavity.


What are its other benefits?

Fast-acting, long-lasting, fragrance-free odour removal developed with Cambridge University

Effective on a wide range of different malodours (eg. sweat odours, urine odours, damp dog odours, chemical odours, and other unpleasant smells ….)

Helps safely remove allergens including dust mite, cat and dog, on contact, when sprayed on surfaces

Highly versatile – works in powder, liquid form, paper products, as a coating or in films and is effective in highly diluted aqueous formulations

Environmentally friendly, degradable under environmentally relevant conditions, Cradle-to-Cradle Platinum accredited, and delivering pure, clean air

Human and pet friendly, our UK pilot consumer product Oderase® with AqFresh™ is endorsed by Allergy UK

How effective is it?

AqFresh™ reduces formaldehyde from 40% above WHO limits to 57% below.*

Eurofins validated that in just 6 hours AqFresh™ cleared 69% of the formaldehyde in a room.

*WHO Guidelines accepted formaldehyde levels (
