Healthy air at home is not a luxury. In this living room, the homeowners chose to add extra ventilation with Wilms wall ventilation featuring Airria® technology. This decentralised type D ventilation system provides mechanical supply and extract, with a constant intake of fresh outdoor air and removal of stale indoor air, without unnecessary heat loss. This keeps the indoor climate pleasant, without having to open the windows.

Because the system works room by room, you can ventilate exactly where it’s needed, without complex air ducts or major demolition work. Thanks to integrated heat recovery, part of the heat from the extracted air is reused. This helps keep the home at the desired temperature while ventilating. In summer, there is also night cooling, ideal for bringing in fresh air at night without air conditioning.

Maintenance is simple too. The filters are easy to replace yourself, and there are variants that help trap dust, pollen and fine particles.
