John: Hey Derek, thanks for inviting us to your home.
Derek: No worries, please come in, it is so cold outside!
John: Oh, it smells good, very refreshing and creates a cozy atmosphere.
Derek: Yes, that’s my wife’s favorite, lemongrass! You know, in winter we seldom open the windows to avoid losing the heat. Those essential oils bring a nice feeling inside.
John: Yes, but mold on the wooden furniture can give off some bad smell. Covering the smell will just let the mold grow and at the end make you sick!
Derek: Oops, I didn’t know it. Let’s do it now!!!!
John: And the burning could release harmful gasses (called Volatile Organic Compounds). It’s better to ventilate after burning anything at home.
Derek: Interesting! I will take the habit of ventilating a bit after burning those oils.
