If you suffer from asthma or allergies, you’ll know that even the most microscopic particle of pollen can trigger an attack. To ensure you can always breathe hospital-grade pure air, we give you the option of adding an intensive 4-stage filtration system to your Gen III.

In stage 1, air passes through the Purtech Return Air Grille, removing 78% of general household dust. The second stage sends the air through a disposable, 50 mm thick prefilter. In stage 3, any dust, pollen or bacteria left in the air is then captured by an incredibly efficient 100 mm thick disposable filter that removes up to 95% of particles as tiny as 1 micron. The final 4th stage subjects air to an ultra violet radiation sterilizer.
