Ventilating your home correctly not only makes your home feel more comfortable but considerably improves air quality. This can have a massive positive effect on your health, especially if you suffer with asthma or other respiratory disorders. This also helps fight the propagation of mold if not eliminating it entirely. Ventilation measures can vary from a simple dMEV install (decentralized mechanical extract ventilation) to a full house MVHR (Mechanical Ventilation and Heat Recovery) system.
