You can get ones that you plug in your car.  You want to eat as much organically grown food as possible.  You want to drink filtered water.  You want to get as many chemicals out of your diet as possible and reduce this pressure on your immune system. If you have food allergies you want to have a 5 day rotation diet.  And you want to take the wonderful digestive aid which has the pepsin and the betaine hydrochloride which will help a person digest the proteins down into single amino acid.  And it’s the proteins and the allergens such danders and foods and pollens and dust that cause or initiate an attack of asthma.
