Creating Healthy Indoor Environments

Did you know? Canadians spend 90% of their time indoors 15-20% of children have asthma 50% of Canadians have some type of allergy It takes a new home approximately 15 years to fully off-gas pollutants in common building materials

What to look for in an Air Filtration Unit Carbon filter for adsorption of VOCs/odors Particulate filter: medical grade HEPA filter Housing material: does it off-gas? Is it painted? If so what kind of paint is used? DOES IT PRODUCE OZONE?

DOES IT PRODUCE OZONE?

Ozone The natural ozone layer up in the stratosphere is good for the environment and for us. It filters out harmful sun rays. At ground level, ozone is dangerous. Ozone is an irritant gas that can cause respiratory problems.

Ozone is an irritant gas that can cause respiratory problems.

Why some argue Ozone is a good choice for Air Cleaning Ozone is very volatile and can react with some chemicals and VOCs. This reaction will neutralize some substances, reducing odors. HOWEVER the same chemical reactions that neutralize odours and chemicals can produce other harmful chemical by-products.

Canadian Regulations Health Canada has issued warnings against using ozone generators Ozone generating devices for home use are NOT approved by the CSA (Canadian Standards Association). Most ozone generating devices for home use are sold door to door or online where they can avoid meeting regulatory standards.

Causes of Large-scale Mold Problems Improperly ventilated dryer, stove and bathroom fans. Leaky roof Piping that is poorly maintained or not maintained at all Lack of natural building ventilation

Solutions & Prevention

Find the Root of the Problem If you discover a mold problem in your home, bring in an expert to find the root cause and repair it at the source.

Reduce Humidity Get a dehumidifier Remember to use bathroom fans when showering and for 30 minutes afterwards Remember to use stove fans when cooking, especially when boiling food

Improve Air Movement If you don’t have a bathroom or stove fan, install one. If for some reason you can’t install one, open a window when showering or cooking When possible, keep doors inside the house open to allow air movement throughout. This is especially important for rooms that lack windows or ventilation. Consider air movement when organizing furniture, and try to avoid placing items where they could block air flow

Clean Water Leaks Right Away If you have a water spill or leak, address it immediately A larger water leak requires expert help, industrial drying equipment, and may require pulling out wet building materials (carpets, and very wet drywall) to ensure that other building materials can be saved After a water leak, mold will grow within 24-48 hours Never delay water clean up!

Anti-Microbial Treatments A mold expert will usually recommend treatment with an anti-microbial spray for a large problem Cleaned areas can then be treated with an anti-microbial sealer to prevent future growth Anti-microbial sealer can also be used as a preventative measure in areas where mold could eventually be a problem such as basements and crawlspaces
