You Deserve Better Indoor Air Quality | Air Cleaners
Today’s tightly built homes trap air particles inside, which is why the EPA estimates indoor air is often 2-5 times more polluted than outdoor air. | Air Cleaners |
Air pollutants are among the top five environmental health risks. Typically the best method of addressing this risk is to control or eliminate the sources of pollutants and to ventilate a home with clean outdoor air. Should ventilating a home be ineffective or insufficient an electronic air cleaner may be useful.
The first electrostatic or Electronic Air Cleaner was developed by G.W. Penney of the Westinghouse Co. in 1935. The “Precipitron”, came out of “a successful failure” in research, and a hopeful house-cleaning experiment in Pittsburgh. By the 1940’s, the Precipitron was used in hospitals, factories, offices and homes electrocuting dust and dirt out of the atmosphere. Westinghouse eventually left this industry but Electronic Air Cleaners have continued to evolve over the years.
What does an air cleaner do?
At a basic level, an air cleaner should filter out the particles that cause irritation such as pollen, spores, dust and other contaminates that circulate in our homes every day. In order for any air cleaner to work correctly, the particles must pass through it. Therefore, if the particles are not in the airstream (i.e., dust on furniture), it is unreasonable to assume that these particles will be removed. However, a good air cleaner will:
- Handle a large volume of air efficiently.
- Remove allergy-causing particles that pass through it.
- Perform well consistently.
- Be economical to maintain.
There are two basic ways of cleaning the air- Mechanical cleaners, which draw air through a filter to capture particles, and Electronic Air Cleaners. Electronic air cleaners include electrostatic precipitators (which charge the airborne particles so they stick to a metal plate) and ionizers (which cause particles to be deposited on nearby surfaces). Some air cleaners are hybrids of the two technologies, and some additionally have UV features or special filters to remove some gaseous pollutants. A variety of electronic air cleaning devices are available. Some are portable and can be used to clean the air in a single room or space, while others are designed to be installed in the ductwork of a home’s heating and cooling system. Each type of electronic air cleaner is designed to remove certain types of pollutants.
