The Fresh Air option is a stand-alone or fully integrated product that works with your ducted air-conditioning system to give you both the comfort of air-conditioning and the freshness of outside air. Fresh Air works in two ways:
bringing the outside in or recycling the air existing in the house. In the three source system, this will add in an evaluation of the roof space heat and consider using this as well.On automatic, Fresh Air is so efficient its been independently tested to have energy savings of up to 22% compared to similar systems without Fresh Air.
All sources of the system, from outside, roof space or inside the house are filtered by a 2 or 3 layer electrostatic filter that leaves the air clean and free of dust and particles. These filters do require cleaning from time to time.

The Pure Air system is an option that should be considered by families with members who have allergies or asthma. It is an air filtration systems far better than those usually provided with reverse cycle systems available for home air-conditioning. Advantage Air’s ‘Pure Air’ features an intensive 4-stage filtration system. In Stage 1, air passes through the ‘Purtech Return Air Grill’, removing most of the particles of general household dust. The second stage sends the air through a disposable, 50mm thick prefilter. In stage 3, any dust, pollen or bacteria left in the air is then captured by an incredibly efficient, 100mm thick, disposable filter that removes the remainder of particles, as tiny as 1 micron. The final 4th stage subjects air to an ultra violet radiation sterilizer. All 4 stages work together to produce a quality of air in the rhelm of cleanliness hospitals demand. The Pure Air filtration system will clean and sterilize the air in about 30 minutes in a typical house (150m2). It can also be installed to filter the entire air supply to an individual room. The Pure Air option is designed to work in conjunction with the Gen III control system.
