Airtight Windows and Suffocating Indoor Air
In older apartment blocks or recently renovated homes, airtightness becomes a major issue. Once old windows are replaced with new plastic ones, natural air circulation stops completely. Moisture begins to accumulate in the rooms, windows are covered in condensation every morning, and eventually, dangerous black mold can appear in the corners.
Ventilating by opening windows is not always a viable solution. An open window in winter releases precious heat in minutes and drastically cools the room. If you live near a busy street, it also lets in noise and exhaust fumes. The apartment gets too stuffy to sleep in, but there is simply no space to install a centralized duct system.
A Personal Fresh Air Port in Your Bedroom
A mini heat recovery unit solves this problem in just a few hours. Installed directly through your room's wall, this compact device continuously supplies fresh, warmed air from outside. Your bedroom constantly maintains the perfect oxygen level, so you wake up refreshed in the morning without feeling groggy.
You no longer have to compromise between warmth and freshness. The heat exchanger inside the mini HRV captures the room's heat before expelling stale air outside, and transfers it to the fresh incoming stream. This completely eliminates moisture problems, protects your home from mold, and keeps heating bills to a bare minimum.
Up to 85% heat recovery - a wall-mounted mini HRV lets you enjoy the freshness of an open window without losing expensive indoor heat, even in the coldest winter.
