Poor indoor air quality can trigger asthma and allergies, and i t can also be the cause of common ailments such as a stuffy nose, headaches, and fatigue. The irritants floating in your home's air may range from relatively minor ones, such as dust mites and animal hair, to the more serious problems of mould and gasses from building materials, furnishings, cleaning products, and heating systems.

A healthy home is one that helps you breathe easier.  It's well ventilated and furbished with materials chosen to reduce off-gassing. For example, in Home 2000 a heat recovery ventilation system supplies fresh air to all living spaces, and exhausts moist, stale air from the bathrooms and kitchen – especially benefiting people with asthma or other respiratory conditions. Low-emission ply wood and finishes, hardwood and ceramic flooring, solid wood cabinets, mouldings and baseboards also help to keep the air clean.
