Every day you hear about another awful contaminant that can get into your home’s air supply. Radon gas. Carbon Monoxide. Nitrogen Dioxide. Smoke. Mold. The list gets longer with each passing year and many homeowners are understandably worried. However, before you run out and by the newest lineup of filters, purifiers, and UV lights, stop and think about just how bad your indoor air actually is.
When Was Your Home Built?
Homes built in the last 10-15 years tend to be well ventilated and may even have air quality systems already in place. It’s those built in the late 1970s and early 1980s that tend to have the worst ventilation (assuming they have not been updated since then).
This kind of poor ventilation can be dangerous, but usually only in that you have less fresh air and more indoor allergens and contaminants. Specifically, you’re most likely to suffer from things like pet dander, dust, pollen, and dirt in the air. On their own, these are not dangerous, but without fresh air to circulate them outside and ensure you get a steady, clean supply of air to breathe, they can make you ill.
How Bad Can It Get?
While it’s rare, some homes suffer from more advanced contaminations. The most common is mold. Mold grows primarily in dark, damp spaces. If your humidity levels get too high in the summer, the ductwork in your house is perfect for mold and it will blow the spores directly into your air, putting everyone at risk.
You should also be wary of exhaust fumes from your appliances that may not get properly removed from the house. Both of these problems can be fixed with regular duct and exhaust cleaning.
Outdoor contaminants can also make it into your indoor air. Things like exhaust and smoke, gas, radon, or other outdoor pollutants should be tested for when you setup a new indoor air quality system. There are filters and purifiers that will remove almost all of these contaminants, but they are not always required, so you should check before making a decision.
Ultimately, the odds are that your home suffers only from some stale, dusty air. But, it is very important to keep everything clean and test it regularly to make sure nothing worse develops. Poor air quality is about more than just comfort – it’s an honest health issue.
