Why good ventilation matters
The hidden problem indoors
We spend about 90% of our time inside, and the air indoors can be up to five times more polluted than the air outside. Everyday life produces pollutants, from cooking and cleaning to heating, pets, and even breathing. Without proper ventilation, dust, pollen, allergens and excess humidity build up quickly, reducing comfort and potentially affecting health.
Fresh air makes the difference
Mechanical ventilation with heat recovery (MVHR) keeps indoor air fresh, healthy and comfortable all year round. By removing stale air and bringing in filtered, tempered fresh air, systems like DUCO cut down humidity, reduce allergens, and stop pollutants from hanging around. The result is healthier living spaces and happier customers.
