After construction is complete, there are a few simple things you can do to ensure the space you move into, is as healthy and non-toxic as possible.
Extra Cost: <$1,000
What: Do a thorough cleaning of every surface before you move in. Also, don't fill your non-toxic home with toxic furniture, as you will defeat all of the effort you just put in.
Why: Construction dust and chemicals get stuck to everything, from floors to walls to ceilings, even though you can't always see it. Most furniture can also have toxic finishes, or toxic foam.
How: Perform a deep clean before you move into your newly constructed space. When buying furniture, try to stick to organic, non-toxic types. Most importantly, buy an organic, latex mattress. You spend 1/3 of your life in your bed, with your head right next to your mattress, so this is an important piece of furniture to buy organic.
