ERV Systems

Fresh Air In. Stale Air Out.

Urban homes constantly face a trade-off. Open the windows and pollution enters. Close them and air becomes stale and heavy. An ERV system removes that compromise.

What We Provide

We supply and install compact, high-efficiency window-integrated ERV systems designed specifically for urban apartments and retrofit homes.

Why Window-Based ERVs

There are two main ERV formats — centralized ducted systems and compact wall or window-mounted systems.

• Ducted systems require structural planning during construction
• Window units are easier to install in existing apartments
• Less invasive and faster to deploy
• Ideal for high-rise retrofits

For most urban residences, window-integrated ERVs are the most practical and scalable solution.

How It Works

• Fresh outdoor air is drawn into the unit
• The air passes through filtration before entering the home
• Stale indoor air is simultaneously exhausted out
• A heat-exchange core moderates temperature transfer

The air coming in contains fresh oxygen from outside. The air leaving carries excess carbon dioxide and accumulated indoor pollutants out.

Continuous exchange. Controlled airflow.

Why This Matters in Cities

• Construction dust infiltrates through open windows
• Traffic exhaust increases particulate exposure
• Sealed interiors trap carbon dioxide
• Natural cross-ventilation is limited in high-rise buildings

An ERV allows windows to remain closed — while filtered fresh air continues to circulate.

• Lower indoor CO₂ levels
• Reduced dust entry
• Improved air movement
• Support for low-VOC interior environments

Built as Infrastructure

Materials reduce internal emissions. Ventilation manages air turnover.

ERV systems act as the mechanical backbone of a controlled urban indoor environment.
