4-8 m² pyramid air purifier: office and wardrobe
The AIRPURLABS 60 g Pyramid air purifier cleans a 4 to 8 m² space — office, walk-in wardrobe, shelf — without electricity, without a filter to change and without releasing any by-products. Its pyramid shape stands directly on a desk or shelf. It binds formaldehyde permanently, a common carcinogenic pollutant, captures volatile organic compounds (VOCs) and neutralises stubborn odours (cigarette smoke, mould, drains). Its efficacy was measured by the independent FCBA institute according to ISO 16000-23: −44% formaldehyde within 24 hours and around −30% for the other VOCs tested (toluene, n-dodecane), in a test chamber.
A technology born of research: two capture mechanisms
The AIRPURLABS® active ingredient traps pollutants in two ways:
-
By chemisorption, for formaldehyde. This very small, highly volatile molecule is poorly retained by conventional absorbers, which release it again. Here, a specific reagent binds it permanently within the active ingredient, where it is converted into a stable compound that remains trapped there. No pollutant is released into the air: once captured, the formaldehyde does not come back out.
-
By adsorption, for the other VOCs (benzene, toluene, n-dodecane…). These molecules bind to a high-performance activated carbon: 1,000 m² of exchange surface per gram, giving 6 hectares of contact surface in this 60 g purifier.
This formulation is the result of a year of research with the CNRS and the Université de Haute-Alsace, and is covered by a patent.
The wool pad, housed in a compact, discreet pyramid casing, lets air circulate continuously. No batteries, no plug, no noise.
What it neutralises
- Volatile organic compounds (VOCs) emitted by new furniture, paints and coverings, household products and combustion (road traffic, fireplace, candles, incense…)
- Formaldehyde, a carcinogenic pollutant common in indoor air
- Cigarette and stale tobacco odours
- Mould odours
- Sewer and drain odours
- Litter tray odours...

Frequently asked questions
What is the difference from the 4-8 m² pad model?
Same active ingredient and same efficacy: only the format changes. The pyramid stands on a desk or shelf, while the pad slips into or hangs in a small space.
How long does this air purifier last?
Up to 2 years in a 4 m² room, up to 1 year in an 8 m² room. The actual lifespan depends on the level of pollution in the room: candles, incense and cigarettes speed up the saturation of the active ingredient.
Does it really work without electricity?
Yes. The AIRPURLABS® active ingredient works through simple contact with the ambient air — no power supply, fan or battery is needed.
Where is it made?
In France, in Strasbourg, in an ESAT (a sheltered workshop providing employment for people with disabilities) run by the Fédération des Aveugles du Grand Est — a manufacturing choice rooted in the social and solidarity economy.
The colour I received is slightly different from the photo. Is that normal?
Yes. The active ingredient contains charcoal, which can slightly alter the shade, especially on light colours. This does not affect its efficacy.
