What is a home ventilation system and how do they work?
As homeowners, we often focus on making our homes more comfortable by keeping the temperature just right. However, an essential aspect of home comfort that is often overlooked is indoor air quality. Poor indoor air quality can lead to a number of issues for both your home and your family. One way to improve the indoor air quality of your home is by installing a home ventilation system.
What is a home ventilation system?
A home ventilation system is designed to circulate fresh air throughout your home and remove stale air. This not only ensures that the air that you breathe is fresh, but it can also help to manage moisture issues in your home.
A ventilation system works by exchanging indoor air with outdoor air, providing a constant flow of fresh air into your home.
There are several types of home ventilation systems available and ensuring that the system you install is right for your home is important.
How does a ventilation system work?
A home ventilation system typically consists of a fan, ductwork and vents. The fan pulls in the outdoor air and circulates in through the ductwork into the various rooms of your home.
As the fresh air enters, it pushes the stale air out. Some systems also provide filtering and condition the incoming air to remove pollutants, regulate humidity and control temperature.

The Lossnay Ventilation System
The Lossnay Ventilation system from Mitsubishi Electric is a patented heat recovery ventilation solution that uses fresh air from outside (not dusty attic air) to ventilate your home. The system was designed specifically for New Zealand conditions and works by extracting stale air from inside your home and replacing it with allergen-reduced fresh air from outside.
Lossnay’s unique Heat Recovery Technology collects up to 86% of the heat energy in outgoing air which is then used to pre-warm or cool the fresh air vented in. In doing so, moisture build up in your home is minimised while healthy humidity levels are maintained and managed in the most energy efficient way possible.
The benefits of having a home ventilation system.
There are many benefits that a ventilation system will bring to your home, most specifically:
1. Improved air quality
A home ventilation system helps to improve the indoor air quality of your home by removing pollutants, allergens and stale air

Home Ventilation FAQs
Why do I need a home ventilation system if I already have heating or cooling?
Heating and cooling systems control temperature, but they don’t always address air quality or moisture. A home ventilation system continuously brings in fresh air and removes stale, damp air, helping to improve indoor air quality and create a healthier living environment for your family.
How does a home ventilation system improve indoor air quality?
A ventilation system works by replacing stale indoor air with fresh outdoor air, reducing pollutants, allergens, and excess moisture. Many systems also include filtration to help remove airborne particles, ensuring the air you breathe inside your home is cleaner and healthier.
Can a ventilation system help with condensation and mould problems?
Yes. One of the key benefits of a home ventilation system is moisture management. By reducing humidity and removing damp air, ventilation systems help minimise condensation on windows and lower the risk of mould growth throughout the home.
