Did you know?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

VOCsVOCs
Volatile Organic Compounds
VOCs are chemical compounds that are in a vapour state. In this state we can easily breathe them in.

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?

OzoneOzone 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.
![Page 12: How to Improve your Indoor Air Quality](https://reader034.fdocuments.net/reader034/viewer/2022051111/555beb66d8b42a38078b5376/html5/thumbnails/12.jpg)
Why some argue Ozone is a Why some argue Ozone is a good choice for Air Cleaninggood 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 RegulationsCanadian 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.

or flood, provided steps are taken immediately to resolve the problem
HOWEVER most home insurance does not cover mold which can develop later, or as a result of improper flood repairs
Check your policy to find out what is and is not covered

Reduce HumidityReduce 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 Improve Air MovementMovement
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 Clean Water Leaks Right AwayAway
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 TreatmentsAnti-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
