How it works
A patented process combining two components: ultra-porous activated carbon, which captures VOCs, and acetoacetamide, which binds formaldehyde.

1. Activated carbon captures VOCs
Activated carbon is an ultra-porous carbon, made from bark or non-resinous wood heated with steam and oxidising gases. The result is a very large contact surface: around 1,000 m² per gram for our carbon.
Volatile organic compounds (VOCs) in the air bind to this surface. That is why activated carbon has long been used to purify water and air.
Absorption or adsorption?
- Absorption: one substance fills another, like a sponge soaking up water.
- Adsorption: molecules attach to the surface of a solid. This is how activated carbon works.
2. Acetoacetamide binds formaldehyde
Formaldehyde is one of the most worrying VOCs in indoor air, classified as carcinogenic. Acetoacetamide reacts chemically with it: formaldehyde is bound by an irreversible bond, not merely retained.
Together, the two components act on various VOCs, on formaldehyde and on some odours linked to these compounds, notably cigarette smoke.

3. Air circulates, without electricity
The constant movement of air in the room is enough. The textile casing lets air through and brings pollutants into contact with the active ingredient. No motor, no filter, up to 2 years of action depending on conditions of use.

Where does formaldehyde come from?
Building and furniture
- Engineered wood panels (plywood, MDF, chipboard, OSB)
- New furniture made from glued panels
- Laminate flooring, PVC floors, glued carpets
- Adhesives, sealants, varnishes, paints
- Some older insulation materials (urea-formaldehyde foams)
Household activities
- Tobacco smoke
- Scented candles and incense
- Fireplaces, stoves, boilers
- High-temperature cooking
Everyday products
- Household cleaners and disinfectants
- Air fresheners, sprays, diffusers
- Nail varnish, hairsprays, cosmetic glues
- Treated textiles, wallpapers and their pastes
Other sources
- Hobby glues, solvents and paints
- Electronic devices that heat up
- Chemicals stored in an adjoining garage
Measured results
Tests by the FCBA institute according to ISO 16000-23, in a test chamber*:
- −44% formaldehyde, within 24 hours
- around −30% for toluene and n-dodecane
* “Test de performance en chambre d’essai d’émission pour l’évaluation de la réduction de la concentration en substances volatiles pour un produit sorptif – module dépolluant” (performance test in an emission test chamber to assess the reduction in concentration of volatile substances by a sorptive product), FCBA, report no. 402/15/1247C/1 of 27 July 2016. Test of 3 modules on formaldehyde, toluene and n-dodecane, and re-emission test. Report available on request.
