What does the HA500 do?

The Healthy Air Purifier range covers the inside of your vehicle to a host of different indoor environments. The HA500 is perfect for the home keeping it clean and safe for family and friends. The unit is ideal for those with children or who live on a busy road but protects everyone from dangerous chemicals commonly found in home appliances.

The Background…

We recognise that what makes home, home is about a feeling of comfort, and a large part of that is knowing you’re safe. It’s becoming commonplace knowledge that indoor air quality impacts our health, making illnesses like the flu or covid worse and contributing to long term illnesses. We designed the HA500 to help reduce airborne particles and selected gaseous pollutants in the home. Combining our state of the art DNO-Catalyst with four layers of Hepa-Filtration, and an advanced air flow system you breath easy knowing your house is full of fresh air.

Sustainable:

The HA500 can lower your homes carbon footprint and save you money on your energy bill. Highly energy efficient it costs less than a lightbulb to run, and can reduce the amount of outside air used by heating or cooling systems, in turn making them more energy efficient while keeping your home a healthy space.

Left on “Auto”, it will adjust its speed to the air quality of the room, keeping energy costs minimal (less than a lightbulb) and showing you the quality with a colour coded system.
