It’s taken a while, but the millions of patients using propelled inhalers have finally, and reluctantly made the switch from CFC- propelled inhalers to HFA-propelled inhalers.

The change in law legally occurred on the last day of December last year. Fundamentally, the intent for the change in the law was for environmental reasons. The old CFC inhalers used chlorofluorocarbon. Studies have shown that chlorofluorocarbon is one of the major culprits when it comes to depleting the atmosphere’s ozone layer. When a CFC inhaler is used, the person breathes in chlorofluorocargon along with whatever medicine he is taking. And then, when the person exhales, he exhales the CFC also. When the CFC meets with the ultraviolet light in the atmosphere, the CFC is broken down. This chemical reaction is what triggers a percentage of the ozone depletion.

This country is one of the last of the major industrialized nations to apply the change. Nations such as Canada, Europe, and Japan had all previously made the change.

Americans use medicinal drugs every year for symptoms as different as dog allergies, allergies to pollen, and allergy eye relief. Even though the law changed last year to prevent the old inhalers from being produced and sold, no doubt there are still many people who have yet to replace their old inhalers with the newer ones.

According to the FDA, HFA, or hydrofluoroalkane, is much a much friendlier substance to the environment than CFC.

Since the changeover, users of the new HFA are primarily experiencing two differences. The biggest change is that the newer model inhalers tend to get clogged more frequently whereas with the older inhalers, this was not much of a problem. The other change, from a patient standpoint, is that the taste is a bit different.

It might seem that the tiny amount of propellant in each inhaler wouldn’t make a big difference. But there are million of these inhalers in use around the world each year. Because of this, the change is expected to significantly decrease the amount of harm done to the environment.

When you heat a house during the winter, humidity in the air is sent outside along with the cold air. The optimal amount of humidity in your home is 40 to 55 percent, however, running a heater can drop the humidity in your home down to 5 percent. This lack of humidity can have an effect on your health, furniture and even your utility bills. The lack of humidity can cause or aggravate respiratory ailments and make winter time colds even worse. The dry air also sucks the moisture out of furniture as well, which can even cause it to eventually fall apart. Evaporating moisture on the skin will also cause coolness so you will continually need to adjust the thermostat to remain warm.

When you make the decision to purchase the best humidifier for comfort and health, you must consider the type of heating unit you have, the cubic footage of your home and the hardness of your water. Once you have the cubic yardage of your home you can compare the different types of humidifiers, choosing one which will provide relief to the entire floorplan.

Row-thru humidifiers work through evaporation and only put the amount of moisture into the air that it can handle which would vary depending on room temperature. By-pass humidifiers are the most common furnace humidifiers. The third type is a steam humidifier which works on the same principle as the vaporizers your mother used when you were a child with a cold. These are the most common type of humidifiers sold in retail stores.

Room size humidifiers can sit on a table top and work to return moisture to one room. For the entire house, you would need a free standing unit or a central humidifier that can be tied into the home’s forced air heating system. It is a good idea to oversize the unit you choose which means the moisture level is higher than required for your cubic yardage. This will help make sure that your home stays at a proper level of humidity year round.
