Fresh air is just as important for comfort as stylish finishes or furniture. Many homeowners forget about ventilation during renovation, leading to stuffy rooms, odors, mold, and health issues. Proper ventilation ensures comfort, health, and durability of interiors. The key question is: when is a supply and exhaust system needed?
Why ventilation matters
Modern airtight windows block natural airflow. Without ventilation, humidity, mold, and odors quickly appear, along with headaches and fatigue for residents.
Natural ventilation
Works through vertical shafts and window leaks, but is insufficient in airtight apartments.
When supply and exhaust systems are needed
- plastic windows block natural air exchange;
- dense urban areas with noise and pollution prevent window airing;
- large families increase CO₂ faster;
- rooms without windows (bathrooms, kitchens);
- homes with children, pets, or allergy sufferers.
Advantages of supply and exhaust systems
- fresh air without open windows;
- filtration from dust and allergens;
- moisture removal and mold prevention;
- even airflow across rooms;
- air heating or cooling as needed;
- better energy efficiency.
System types
Local units: compact, room-based solutions.
Central systems: ducted systems covering entire apartments or houses.
Common mistakes
– relying only on natural shafts;
– installing strong kitchen hoods without supply air;
– poor intake placement near pollution;
– skipping filters;
– wrong system capacity.
Tips
- plan ventilation before renovation;
- use supply valves in key rooms if full system isn’t possible;
- regularly test shaft draft;
- change filters on time;
- select system power based on area and residents.
Examples
– In an airtight apartment, a strong kitchen hood disrupted balance; adding supply solved the issue.
– A child’s room suffered from condensation and mold; a local unit fixed the problem.
– Near a busy road, supply with filters provided clean, quiet air.
