measuring PM 1.0 particles (particulate matter with a diameter of less than 1.0 µm). Equipment even has IAQ displays as a matter of course measuring a number of parameters and in a number of different ways – IAQ can vary from good to moderate, unhealthy to poor. It can be monitored and displayed on the unit itself or monitored via an app. It should be remembered that pollutant


In areas with a higher concentration of pollution, research has found that this lower air quality can exacerbate a number of health conditions


removal technology varies according to the equipment measured. t starts with prefiltration of big particles – a multi-layered structure can remove particles up to 2.5 microns and trap big dust particles at the air inlet – this is the basic approach. The addition of an allergy filter will remoe allergy- causing substances, such as house dust mites, oating in the air  helping people who react badly to foreign substances. Dust electrification can be used to


increase the electrostatic charge of particles and improe the efficiency of the fine filters in remoing dust particles. The filtering of ultra-fine particles is the next step, removing 99.9% of PM 0.1 size ultra-fine dust. The P . allergy filter removes allergy-causing substances. It’s possible to purchase equipment that generates over three million ions to remove up to 99% of airborne bacteria, like staphylococcus aureus, Escherichia


coli and Pseudomonas aeruginosa. It also eliminates bad odours that circulate in the air.


Finally solutions are available to


introduce UV-C radiation – an effective disinfection process in this situation. The high-energy radiation destroys the DNA and RNA of the microbes so that they can no longer proliferate, removing bacteria and viruses. You can also specify a new and highly


effectie fie filtration step ir Purification Kit for a Multi Split indoor one-way and single split Dual Vane cassette products. The kit is specifically deeloped for the indoor units of the air conditioning system and is capable of purifying the indoor air, removing particles and VOCs, while conditioning the air. The multi- process air purification kit, fitted into the air inlet of the indoor unit, consists of fie technologies in the order from outside to inside. The first leel is the pre-filter, followed by dust electrification, a P . filter, a deodorisation filter and an ioniser. Clearly this is an area of activity that will continue to grow in importance and see increasing levels of activity from all companies operating in the sector.
