The numbers are shocking. Here in New Zealand, asthma affects one in eight adults and one in seven children.

700,000 people right now are living with asthma or respiratory illness1.

At HRV we believe a healthy home is key to living a healthy life. Damp, cold, poorly ventilated homes are everywhere, and they’re ground zero for respiratory diseases. As a relatively wealthy nation we should be doing better than that!

HRV AirSense™, like the three generations of HRV home ventilation before it, was designed to create a healthier home.

HRV AirSense™ is designed to help in two ways.

Firstly, it filters the air your family breathes when they’re at home. Our exclusive, patented WoolCare™ filter features five layers of filtration with a recycled New Zealand wool core and nanofibre filtration. WoolCare™ filtration is only available with HRV AirSense™ and filters dust, pollen, mould spores and other common allergens and asthma triggers from the air you breathe.

Secondly, HRV AirSense™ reduces the moisture in your home. That means it’s easier to maintain a healthy level of humidity and mould is less likely to appear on your walls and ceiling. HRV AirSense™ does this by bringing drier, filtered air from your roof space then delivering it to your living areas via ceiling vents. Stale, damp air is forced out, replacing it with fresh, filtered air all year round.

The result? HRV AirSense™ is scientifically proven to reduce moisture2, and helps prevent mould.

We haven’t stopped there. New Zealand’s asthma epidemic is a huge challenge and not one that any company or organisation can tackle on its own. So we’ve partnered with the Asthma and Respiratory Foundation to support its important work. We’re proud to be an official Friend of the Foundation.
