Ventilation: The Foundation of Healthy Indoor Climate

Proper ventilation is the foundation of healthy indoor climate for every home and office. A good indoor climate is not just about comfortable temperature — it means clean air, the right humidity level and low CO₂ concentration. In this article we explain why ventilation matters for health and which solutions deliver the best results.

Why is ventilation important for health?

Modern people spend up to 90% of their time indoors. Poor indoor climate causes headaches, fatigue, allergies and respiratory problems. A proper mechanical ventilation system removes used air along with CO₂, moisture, odours and pollutants, and constantly brings in fresh filtered outdoor air.

What does a good ventilation system provide?

• Fresh air — continuous air exchange keeps CO₂ below 1000 ppm.
• Right humidity — 30–60% humidity prevents mould and dry mucous membranes.
• Clean air — F7/ePM1 filters capture dust, pollen and fine particles.
• Energy savings — heat recovery preserves up to 90% of the exhaust air's heat.
• Silent operation — modern units work below 30 dB.
