Filtration – Serving Greater Omaha & Westrn Iowa

Air filtration is one of the most important factors when it comes to indoor air quality. That’s why McCarthy’s One Hour Heating and Air Conditioning has invested time and money into Air Advice Monitoring systems. These instruments can be placed in your home for a week and record the quality of air in your home. The majority categories recorded are:

 

 

  • Particles: Particles are generally a cause for concern when daily average levels are above 10ug/m3 (micrograms per cubic meter of air). Particles are known to trigger asthma and allergy symptoms. At levels above 35 ug/m3, they can harm normally healthy adults by causing emphysema and diminished lung capacity. Children, the elderly and pregnant women are more susceptible.

 

 

 

  • Chemicals: Chemical pollutants are generally a cause for concern when average levels are above 500 ug/m3 (micrograms per cubic meter of air). Chemical pollutants are known to trigger asthma and allergy symptoms. At moderate levels, eyes and nasal passages can be irritated. Some people can experience nausea and headaches. At very high levels, they can even affect normally healthy adults by overworking their liver and kidneys. Children, the elderly and pregnant women are more susceptible.

 

 

 

  • Carbon Dioxide: Carbon dioxide (CO2) levels above 750ppm (parts per million) are a cause for concern. At higher levels, CO2 inside a home can contribute to what the EPA terms “sick building syndrome”, which leads to fatigue, headaches, breathing difficulties, nausea, strained eyes, and itchy skin. at even higher levels, CO2 can cause asphyxiation as it replaces oxygen in the blood. CO2 poisoning, however, is very rare. The U.S. EPA recommends a maximum concentration of CO2 of 1000ppm for continuous exposure.

 

 

 

  • Temperature: Comfortable temperatures fall within the range of 68 and 75 degrees Fahrenheit. In addition, temperatures are most comfortable when steady, with fluctuations less than 1-1/2 degrees. Ideally, the temperature should be constant between all areas of the home. People experience a chilling or ‘goose bump’ sensations when temperatures are uneven and when air blows quickly across the surface of the skin.

 

 

 

  • Relative Humidity: According to the ALA the relative humidity should be 50%, with levels in the 40-50% range offering the most comfort possible. The amount of moisture in the air influences both health and comfort. When the air is too dry in the winter, people typically feel colder. Also, respiratory passages can become irritated and prone to infection.

 

 

 

  • Carbon Monoxide: Carbon monoxide is a cause for concern when average levels are 6ppm or higher. When levels are above 25ppm, immediate action should be taken. Carbon monoxide is a colorless, odorless, poisonous gas produced by combustion. When people are exposed to relatively low levels, it can cause headaches and nausea. At relatively high levels, it can cause memory problems and ultimately death.
