Feeling down in the damp? Ventilate!

Crisp, clear, cool winter days are great when you’re out walking in your favourite coat and beanie.

What’s not so great is waking up to a home that feels damp. Opening the curtains to condensation on the windows and puddles on the windowsill. Or reaching for that favourite coat from the back of the wardrobe to find it’s got mould on it!

Dampness doesn’t just affect how your home feels; it can be bad for your health too. Dampness and mould growth can exacerbate asthma and increase the risk of asthma onsetting. Indoor dampness and mould is also associated with an increased risk of respiratory tract infections and bronchitis¹.

If dampness and mould are what you’ve come to expect every winter, you might think that it’s par for the course.

It doesn’t have to be!

Winter moisture, damp clothes and furnishing, condensation and – yuck! – mould can all be reduced by making sure your home is well ventilated all year round.

It’s pretty simple in principle. In winter especially, we tend to close all our doors and windows to keep the heat in. The problem? That also means the moisture we create all the time by showring, laundry, cooking and even breathing has nowhere to go. So it hangs around, the air gets damper and before you know it, it feels like you’re living in a giant wet sponge.

HRV AirSense™ was designed to tackle this problem. It works by bringing drier air from your roof space, filtering it, then delivering it to your living areas. The incoming drier, filtered air forces the damp, stale air out through gaps in your doors and windows, filling your home with fresh air.

In fact, HRV AirSense™ is a New Zealand home ventilation system that is scientifically proven to reduce moisture², and helps prevent mould.

We worked closely with researchers at Auckland’s Unitec to test HRV AirSense™ home ventilation in real-world conditions. The results speak for themselves.

It’s surprising what we can put up with if we live with it for long enough. Dampness and mould don’t have to be a part of your winter though. Show it the door with effective home ventilation, lower the health risks associated with dampness and mould… then get outside and enjoy those crisp winter days!
