With an inhaler, you remedy symptoms such as asthma or breathing problems from allergies. There are inhalers where you inhale the medication directly through your mouth. In addition, there are nebulizers that you place over both your nose and mouth. This makes inhaling easier, especially for children. You also waste less medication as the medication doesn't go past the mouthpiece into the air. Do you have a lot of respiratory problems and want to use an inhaler or nebulizer on the go? Choose a compact inhaler that you don't use on the power grid. The larger devices are less convenient to carry with you, but usually work faster.
