EvoAQ Ventilation System



Smarter Fresh Air Technology


Unlike conventional ventilation systems that only react to what’s happening inside your home, the EvoAQ system takes a smarter approach.


  • Outside-In Thinking – EvoAQ monitors the quality of the air coming into your home, not just what’s already inside.
  • Adaptive Technology – Using locally developed complex algorithms, the system learns and adapts to its environment.
  • Automatic Adjustments – EvoAQ automatically fine-tunes its operation so you don’t have to.
  • Better Comfort & Efficiency – You get healthier, fresher air while the system optimises itself for energy efficiency.


This makes EvoAQ the only system of its kind in New Zealand, designed to give you complete peace of mind and the best indoor air quality possible.
