When you have a central furnace and air conditioning system, air quality often becomes an issue. These types of systems use duct work to transport air throughout your home. As one vent delivers the heated or cooled air to the room, another vent is drawing air into the duct work to be sent back to the furnace or air conditioner. The air in your home will cycle through the system at least 45 times or as much as 140 times a day, depending on how much you run your HVAC systems. Dust, dander, pollen, mold spores, and many other microscopic particles are being cycled along with the hot or cold air. This constant recycling of polluted air is often what leads to poor indoor air quality.
Your furnace and air conditioner should have an air filter as your homes first line of defense against these nasty particles. But, finding the right air filter for your home can become very frustrating once you find out how many choices you have. The four main types of air filters that are on the market for residential HVAC systems include: Read more
New studies are providing more evidence that poor indoor air quality can be just as bad for asthma sufferers as polluted outdoor air.Â Substances such as cigarette smoke and pet dander, as well as the level of humidity can promote asthma or asthma-like symptoms in humansâ€”especially small children.Â It is important to try and keep your indoor environment as clean as possible and little things such as only smoking outside, dusting and vacuuming regularly, and choosing pets that are less prone to things like shedding can make a difference in comfort levels.
Unfortunately, scientists still do not know why some people develop asthma and some donâ€™t.Â Whether is a genetic disposition or an environmental problem, scientists do know that the number of asthma suffers is rising.Â More studies are necessary to find conclusive causes of asthma.Â However, from studies that have already been performed there is strong evidence that controlling indoor humidity below 50%, avoiding pets (or at least choosing them wisely), and minimizing chemical pollutants such as cigarette smoke can greatly reduce the amount of asthma symptoms in people.
