From PIV to MIV® - Positive Input Ventilation has Evolved
In the last 25 years, the number of new asthma cases in the UK has increased six fold among children and three to four fold in adults. Asthma now affects more than five million people in the UK and kills 1,500 a year. Poor ventilation causes high levels of humidity which in turn increases the levels of dust mites - a known trigger for asthma. As we build tighter homes and continue to ‘seal up’ existing ones the requirement for good ventilation is becoming paramount.
