Traditional fireplaces are cozy and wonderful; however it is no secret that they are not so great for the environment. Their smoke can pollute the air both inside and out, and lead to respiratory problems. According to the EPA, the smoke that fireplaces generate carries harmful particles, including volatile organic compounds and even benzo(a)pyrene, a carcinogen. So, should you close up your fireplace once and for all? Not necessarily, as there is a greener option available – the bio ethanol fireplace.
