The best solution is the Heat Recovery Controlled Ventilation (VMC). After two years of experimentation, the PosaClima Team has developed PureAir, a specific machine that reciprocates the air continuously, without disruption and without energy waste, allowing to solve the problems of mold and condensation without having to open the windows, which also means having a better soundproofing and to prevent someone from getting into the house easily. Airing with PureAir means saving money, having more comfort, more safety and an improvement in internal sanitary conditions. The machine has received the prestigious seal "VMC Qualità CasaClima", the first among the non-ducted wall machines, reflecting its performance qualities
