Each and every one of us requires fresh air to survive, with each person exhaling between 10 and 75 litres of carbon dioxide and 175 grammes of water vapour per hour. A family of four produces between 10 and 15 litres of water vapor each day through cooking, washing and breathing. Dust mites have proven links with over 80% of asthma cases and thrive when humidities are high. What’s more within a typical home there are traces of ammonia, acetic acid, methane, nitrogen monoxide and formaldehyde from cleaning products and building materials.
Unless ventilation is added these contaminants will linger within the home and will affect both the health of the occupants and can lead to damage to the fabric of the building itself. A well designed fresh air system can reduce these levels significantly, replacing contaminants with clean fresh air.
