Air Filters for Allergies
Which Portable Air Filters for Allergies are Right for Me?
Are you suffering from allergies? Did you recently remodel your home and are bothered by noxious odors? Wondering which Air Filters for Allergies are right for your home or office? Or maybe you want to take preventative action against any possible indoor airborne pollutants in the form of particulates like mold spores or pollen and/or in the form of gaseous pollutants like combustion byproducts, cleaning products, and offgassing building materials. A number of portable air filters are sold by hardware and department stores, and over the internet. These air cleaners can help to remove these pollutants. Below is as list of different types of portable air filters:
HEPA Air Filters for Allergies
We commonly recommend use of portable HEPA (high efficiency particulate air) filters removes at least 99.97% of air particles as small as 0.3 micrometers. These filters are built under strict Department of Energy standards. HEPA filters can be used with most cleaners and purifiers, and with certain vacuum cleaners. Pre-filters can also be used to block large particles from coming in contact with the HEPA filter, to prevent it from becoming damaged or clogging. They can be washed repeatedly and would help your filter to last longer.
Activated carbon filters consist of small pieces of carbon that have been treated to be more porous, which allows the carbon to adsorb contaminants. These filters are often used with HEPA or other filters. Because of their ability to pull odors and gases, activated carbon filters can be very effective in conjunction with other filters that would remove particulates from air. Some filters, however, need to be changed often in order to be effective, which could be costly.
Ozone Producing Air Filters for Allergies
We do not recommend using ozone-producing filters! Nor does the EPA, the California Air Resources Board, or any other government agency. According to the EPA, relatively low amounts of ozone inhalation can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections. Some air filters to avoid include Electrostatic Precipitators, Charged Media Filters, and Ion and Ozone Generators. The following link leads to a list from the California Air Resources Board of potentially hazardous ozone generators sold as air purifiers:
Antibacterial and Germicidal Filters
Antibacterial and Germicidal Filters can be helpful in removing organic particulates, which include mold and bacteria. These sometimes use UV light, and they can be used alone or in conjunction with a HEPA filter. While not always necessary, the addition of these filters can provide added protection and peace of mind.
Photoelectrochemical Oxidation (PECO) Air Filters
PECO reactions break down chemicals at the molecular level. The process can be used to purify both air and water. These types of air filters claim to be able to remove virtually any allergen or volatile organic compound from the air through destruction of the chemical compounds, instead of other filters’ methods of adsorbing or trapping contaminants.
