ARS Nordic SMART QR – Technical Data
ARS Nordic SMART QR is not just a ventilation unit – it’s a solution designed to maintain a healthy indoor climate without extra effort.
It continuously refreshes indoor air, reduces excess humidity, preserves heat, and helps prevent window condensation and mold.
Product overview
In many modern homes, natural air exchange is not enough. As a result, humidity builds up, odors remain, windows start to fog, and in some cases mold appears.
ARS Nordic SMART QR solves this in a simple way – it ensures continuous air renewal while maintaining indoor comfort.
The unit operates in cycles, allowing stale air to be removed and fresh air to be supplied in a balanced way. This helps avoid sudden temperature changes and discomfort.
Most importantly, the system adapts to real conditions. When humidity is too high, it helps remove excess moisture. When the air becomes too dry, it helps maintain a more comfortable balance.
The result is a natural indoor feeling – not too humid, not too dry.
This is especially important in airtight apartments, renovated homes, or modern buildings where natural airflow is limited.
The unit is designed for continuous, quiet operation – so you simply forget it’s there.
We don’t sell airflow numbers.
We solve real problems people experience every day – humidity, mold, and poor indoor air quality.
That’s why the focus is not the device itself, but the result – a stable and comfortable indoor climate.
- ✔ Continuous fresh air indoors
- ✔ Reduced humidity and lower risk of mold
- ✔ Heat retention during colder seasons
- ✔ Less window condensation
- ✔ Balanced indoor humidity
- ✔ Quiet and automatic operation

Airflow performance characteristics
Airflow increases linearly across speed levels, allowing precise ventilation adjustment based on room size and ventilation requirements.
Recommended operating range for residential use: speed levels 3–7.
Acoustic performance
Low-speed operation provides near-silent performance suitable for bedrooms and living spaces. Higher speeds enable rapid air exchange for intensive ventilation scenarios.
Optimal operating zone
The optimal performance range provides the best balance between airflow capacity, acoustic comfort, and energy efficiency.
Recommended typical operating range:
• Speed level: 3–6
• Airflow: 35–100 m³/h
• Noise level: 16–28 dB(A)
