Needlepoint Bi-Polar Ionization technology works by producing a high concentration of positive and negative ions, delivering them to the desired space via the given ventilation system or device.  It emits both positive (H+) and negative (O2-) ions. Ions surround harmful pathogens and react as Hydroxyl (OH) radicals. This process removes hydrogen from the cell walls of microbes, inactivating harmful pathogens at a cellular level making them no longer harmful. In turn eliminating over 99.9% of bacteria, mould and viruses present in crowded but also domestic environments. The NPBI technology can be used in all sectors and settings, creating the ideal conditions for the wellbeing of people.

Ion Concentration 

Ions are positively or negatively charged molecules or atoms that occur naturally everywhere in the outdoors. Ions are created with energy from rushing water, crashing waves and even sunlight – they are constantly working to clean the air. GPS NPBI ™ technology (Needle Point Bi-polar Ionization) generates ions without producing ozone or other harmful by products, so you can bring outdoor freshness indoors.

Unfortunately there are lower concentrations of ions indoors

A typical outdoor environment has 450 to 2,000 ions per cc. Ions are naturally occurring and are higher near areas with rushing water or at higher elevations. Ions near waterfalls have been measured at upwards of 19,000 ions per cc. Indoor ion concentrations in buildings without ionisers generally range from dozens to several hundred ions per cc.

Ionisation is the process of using voltage to electrically charge air molecules
