Environmental toxins are not what come to mind for most of us when we are making decisions on building or purchasing a home. So choosing an attached garage is probably not a deal breaker or unthinkable design for the typical home owner. Convenience is what we think of, not shoveling snow or running outside in a rainstorm to get in your car, so it seems like an advantage.
The reality is that our attached garages are potentially poisoning us. The EPA states that the largest source of poor indoor air quality is an attached garage. Think about the amount of toxins that come out of that tail pipe! Then think about how we are pulling our cars right into our homes. We all smell that toxic smell when we step out, but then we open the door to our home and let it come on in with us. Like it’s a party just “come on in!” Those fumes follow right in the door and settle in your home. What’s in those fumes? Carbon monoxide, a deadly lethal gas is one component.
My suggestion is when building or buying, avoid attached garages. If you currently own a home with an attached garage, park outside! Not willing to give up that convenience? Then at least let your garage door to remain open for a few minutes when parking and never allow your engine to idle in the garage. Another alternative is installing a garage ventilation system that can remove these toxins.
Remember what your convenience may be costing you and your family. The best way to keep these poisonous toxins out, is by not letting them in.
