Never has indoor air quality been more important. Reducing the spread of covid-19 in the home is vital. Virus transmission occurs more readily inside than out. Inadequate ventilation and insufficient fresh air allow pathogens to build up, increasing the likelihood of infection. Government advice is for enclosed areas to be regularly ventilated (mechanically or by letting in fresh air). This can reduce infections by over 70%. Control condensation and extract pollution (and pathogens) continuously, economically, at really low noise levels ensuring heat loss is minimal with one product – the Vectaire Midi, Maxi and Maxi Plus MVHRs “BY-AT” models with integral acoustic attenuation and a choice of speeds do all that. Installation is simple – nothing extra required other than the unit itself. They incorporate summer bypass and frost protection, with commissioning via touch screen.
