How to reduce indoor air pollution
It is a good idea to take steps to keep your indoor air clean to avoid the health problems associated with poor air quality.
First step is to measure your IAQ. It includes gases, VOCs and dust. Get yourself IAQ monitor, so, you know what is going on in your home and how your actions change your IAQ.
When you know what you are dealing with, you need to take actions. An easy way to keep your indoor air healthy is to ventilate your home on a regular basis. However, it is relevant only when you leave in clean area and your outdoor air is clean.
If you live in an area of the world where there are air quality alerts, you will want to restrict ventilation to the night or other times when you know there is not an excessive amount of pollution outside. During pollen season or extreme air quality events like nearby wildfire smoke, it is best to keep windows closed. In such case, the usual advice is to invest in good air purifier. There are many on the market and the price range is wide, so, you can find something that suit you.
Another method is to control the sources of pollution in your home. If you have the space, allow new products to off-gas outside your walls or avoid entering a room containing an off-gassing item for a few days. Be sure that dust and moisture are not gathering in the corners and cracks of your home, because dust and moisture are food and water for mold, dust mites and other contaminants.
