LUNOS Ventilation: The Key to a Healthy Home
Fresh Air, Healthy Living—Without Energy Loss
Building or Living in an Airtight Home? Stay Comfortable & Breathe Easy.
Airtight homes are the future of energy-efficient living. They reduce heating and cooling costs, improve thermal comfort, and eliminate drafts. But without proper ventilation, indoor air quality can suffer—leading to CO₂ buildup, VOC gases, excess humidity, and condensation.
That’s why Healthy Homes need smart, decentralised ventilation.

Frequently Asked Questions (FAQ) – LUNOS Ventilation & Heat Recovery
1. Why do airtight homes need mechanical ventilation?
Airtight homes are excellent for energy efficiency and thermal comfort, but without proper ventilation, they can trap CO₂, VOC gases, excess humidity, and other pollutants. LUNOS systems ensure continuous fresh air circulation, preventing stale air, moisture buildup, and mould growth while maintaining your home’s energy efficiency.
2. What is heat recovery ventilation (HRV), and how does it work?
LUNOS heat recovery ventilation (HRV) uses a ceramic heat accumulator inside the ventilation unit. As stale air is exhausted, the accumulator stores heat. When fresh air is drawn in, the heat is transferred back, recovering up to 90% of the home’s warmth in winter and keeping it cooler in summer. This means fresh air without energy loss.
3. How does LUNOS differ from other ventilation systems?
Unlike traditional ducted HRV systems, LUNOS is decentralised, meaning:
✅ No large ductwork required – perfect for retrofits & new builds
✅ Whisper-quiet operation – Ideal for bedrooms & living spaces
✅ High-efficiency ceramic heat exchangers – Up to 90% heat recovery
✅ Low energy consumption – Runs on as little as 1.4W
4. Will LUNOS help reduce CO₂ and VOC gases in my home?
Yes! Without ventilation, CO₂ levels can rise, leading to drowsiness, headaches, and poor indoor air quality. VOC gasesfrom household materials, paints, and furniture can also accumulate. LUNOS systems continuously replace stale indoor air with fresh, filtered outdoor air, ensuring a healthier living environment.
5. Can I install LUNOS in an existing home, or is it just for new builds?
LUNOS is designed for both new homes and retrofits. Unlike bulky ducted systems, LUNOS units install directly into external walls, making them ideal for airtight homes, renovations, and Passive House upgrades.
6. How much maintenance do LUNOS units require?
LUNOS ventilation systems are low maintenance. The filters are easy to clean and only need to be checked twice a year. The ceramic heat exchanger is self-cleaning and requires minimal upkeep.
7. Will LUNOS improve humidity control in my home?
Yes. By continuously exchanging stale indoor air with fresh air, LUNOS helps prevent condensation, mould growth, and excessive humidity, creating a healthier home environment.
8. Is LUNOS suitable for Passive House projects?
Absolutely. LUNOS ventilation systems meet the strict energy efficiency and air quality standards required for Passive House-certified buildings. Their high heat recovery efficiency makes them a perfect choice for ultra-low-energy homes.
9. How do I get a LUNOS ventilation system installed?
SunStak provides expert advice and installation for LUNOS ventilation in Canberra. Whether you’re a homeowner or builder, we’ll help you choose the right system for your project.
