• Asthma is a chronic condition affecting the airways of your lungs. Inhalers are used to control the disease and relieve any sudden symptoms. In 2009, chlorofluorocarbon (CFC) inhalers were replaced with more environmentally friendly, or "green", inhalers.


    When you have asthma, your airways become irritated or inflamed. As a result, your airways become narrow, making it hard to breathe.


    When asthma symptoms---like coughing, wheezing or trouble breathing---worsen, you're unable to breathe. This is called an asthma attack. To relieve these symptoms you'll need to use a rescue inhaler.


    Traditionally, rescue inhalers contained environmentally harmful chemicals to propel the drug into your lungs.


    However, the new hydrofluoroalkane (HFA) inhalers offer you the same benefit without harming the atmosphere.


    With green inhalers, you'll notice a different taste and feel, according to CBS News. Also, you'll need to prime and clean it differently than the CFC inhalers to prevent clogging.
