EVOAQ Ventilation System

Q: How does a whole house ventilation system work?

A whole house ventilation system continuously replaces stale indoor air with filtered fresh air from outside. It helps control moisture, remove pollutants, and maintain healthy indoor air quality. EVOAQ systems use smart sensors to adjust airflow based on real-time conditions.

Q: Do I need a ventilation system if I have an HRV/heat pump?

Yes. While HRV systems recover heat, they don't always provide adequate fresh air exchange. A dedicated ventilation system like EVOAQ ensures proper air changes, removes excess moisture and VOCs, and meets Healthy Homes standards.

Q: Can EVOAQ systems be installed in existing homes?

Absolutely. EVOAQ offers retrofittable solutions for existing homes, including through-wall bathroom fans and whole house systems that can be installed with minimal disruption. Our nationwide installer network can assess your home and provide a tailored quote.

Designed to deliver fresh air, remove moisture, and maintain healthy indoor air quality in New Zealand homes.

The problem with most ventilation systems

Why many homes still suffer from condensation and poor air quality

Rely on roof cavity air – often warm, stale or contaminated
Operate intermittently – turning off when air quality is poor
Do not remove moisture consistently – moisture builds up, leading to mould

This often leads to condensation, mould, and poor indoor air quality.

A different approach to ventilation

The EVOAQ system is designed around continuous airflow and moisture control.

Fresh filtered air

Supplied directly from outside, not from the roof cavity.

Moisture extracted at source

Bathrooms, kitchens, and laundries are actively dried.

Continuous airflow

Fresh air circulates through living areas, pushing stale air out.

Smart sensor control

Automatically adjusts to humidity, temperature, and air quality.

How it works

A balanced flow of air throughout your home

Supply & extract together

Air is supplied into living areas and bedrooms, while extraction removes moisture from bathrooms and wet areas. This creates a controlled airflow path through the home, improving indoor air quality and preventing condensation.

Continuous operation

Unlike systems that switch off when conditions are poor, EVOAQ runs continuously, adjusting speed to maintain air quality while using minimal energy.
