EHT² EFT² — Filtering air inlet for VMC
Incoming air filtered.No filter to replace.Fits every VMC.
Co-developed with the ALDES Group, the EHT² EFT² filtering air inlet combines the air renewal of the VMC with high-performance filtration of outside air, with no consumables and no added running cost.
- Up to 90% of particles
- 2 Pa pressure drop
- 1.5 Watt
- Up to −43 dB
- Made in France

Why choose the EHT² EFT² filtering air inlet?
Compliant with French building ventilation regulations and compatible with every VMC on the market, the EHT² EFT² air inlet replaces a standard air inlet without altering the installation, in new builds as well as in renovation.
It carries TEQOYA's patented e-filtration technology, which combines ozone-free air ionisation with electrostatic filtration: ions produced in a very localised area, under one millimetre, bind to the pollutants of the outside air, which the collector then retains.
High-performance
Tested under the conditions of the NF EN ISO 16890 standard: 90% of particles larger than 10 µm, 80% above 2.5 µm and 77% above 1 µm — particles and aerosols, bacteria, pollen, spores, mould, dust, ash and smoke.
Energy-efficient
1.5 Watt in continuous operation, that is less than €4 a year, with no motor at all. The filter is cleaned rather than replaced: no consumables, no recurring expense.
Durable
No programmed obsolescence, and a large available plate surface: no risk of the inlet clogging in the event of heavy fouling or of missed maintenance.
Discreet
Inaudible in use, it cuts noise coming from outside by up to 43 dB, that is 6 to 8 dB better than a standard air inlet. Understated design, durable materials, local manufacturing.
Winner of the Label Intairieur. The e-filtration technology adapts to many applications: TeqLAB, the TEQOYA engineering office, supports industrial partnerships and co-innovation projects.
Built into the wall, out of sight
The assembly fits the opening of a traditional air inlet: indoor cover, insulated sleeve, filtering module and outdoor grille.

Filtration principle
① Ozone-free ionisation of the incoming air, ② electrostatic collection of the particles, then an acoustic absorber before the air reaches the room.

The filtering module
The plate collector is pulled out and cleaned: there is no disposable filter to buy again, and no stock to manage.

Exploded view
Indoor cover, insulated sleeve, filtering module and outdoor grille: four parts for a single wall opening.
