With modern house sealing techniques that keep the outdoor pollution outdoors, you may think that the air you’re breathing in your house is clean and uncontaminated. That is not necessarily so, according to a study conducted by the University of Surrey. That study notes that “people, particularly urban dwellers, typically spend over 90% of their daily time indoors, where levels of air pollution often surpass those of outdoor environments”.
The World Health Organization reports that there are many incidents of respiratory and cardiovascular disease attributable to indoor air pollution, and they strongly suggest the use of air filtration and purification.
There are numerous sources of indoor pollution, even in immaculately clean homes. There are biological pollutants such as pollen from plants, bacteria and viruses transmitted by people and animals, mold, pet dander, household dust, mites, and many others. Particulate matter can be generated from cooking (especially if the food is fried, grilled, toasted, or burned) and from stoves and other fuel-fired combustion equipment. Many of these contaminants are small enough to be inhaled.
The US Environmental Protection Agency recommends changing the filters on your HVAC system according to the manufacturer’s instructions and having a trained professional perform annual inspection, cleaning, and tune-up of your central system. The EPA and others also strongly recommend that fuel-fired combustion appliances be vented to the outdoors. While that is excellent advice, you may also want to consider an air purification system.
Some systems rely solely on filters. Filters trap airborne particles as the air passes through them. There are many different types of filters such as:
Basic filters are often made of spun fiberglass, pleated paper, or other materials. The filters will have a MERV (Minimum Efficiency Reporting Value) rating. The higher the rating, the better the filter will be.
HEPA filters have a fine mesh to trap particles. The HEPA (High-Efficiency Particulate Air) filters are generally considered to be more effective in removing airborne particulates. HEPA filters will also have a MERV rating.
Carbon filters contain a bed of activated carbon (sometimes called active charcoal) and are most commonly used to remove gases, including volatile organic compounds (VOCs).
Electrostatic filters contain multiple layers. The inner layers are generally made of polyurethane and polypropylene fibers and the outer layers are a polyester mesh. The blend of materials in electrostatic filters creates static electricity which gives each of the filter’s layers an electric charge, some positive and some negative. As particles pass through the positively charged layer, they pick up the positive charge. The positively-charged particles are then attracted to and will stick to the negatively charged layer.
These types of filters all have varying degrees of effectiveness in trapping particulates, including viruses, but they do not kill the viruses.
There are also air purification systems that do not simply filter the air.
UV light air purifiers use ultraviolet light to kill airborne pathogens and microorganisms such as bacteria, viruses, and mold. The UV light systems, sometimes called UVGI (ultraviolet germicidal irradiation), often require the use of HEPA filters.
Ionizers generate and discharge electrons into the air which form negatively-charged ions. These ions attach to positively-charged particles such as dust, bacteria, viruses, pollen, pet dander and other indoor pollutants.
A system we strongly recommend is the REME HALO®. REME is an acronym for Reflective Electro Magnetic Energy. The manufacturer, RGF Environmental Group Inc., conducted numerous tests of this award-winning system. These tests were conducted at independent accredited labs and universities and the test results show an astounding reduction of bacteria, viruses, VOCs, and other indoor pollutants.
We are not the only ones to endorse this highly effective system. The REME HALO®:
- U.S. Military approved for mold reduction in field hospitals
- U.S. and International Hospital approval for the fight against infectious diseases: 99% reduction of Staph (MRSA)
- Major U.S. city school reports 20% reduction in absenteeism
- Tested and approved by the Chinese Government for protection against the deadly SARS virus
- Approved by the USDA, FSIS, and FDA for use in food processing plants. Employed to reduce microbial contamination of food being processed
- Cruise lines use it as a safety measure again Norwalk Virus outbreaks
The REME HALO® is installed into the supply plenum of your existing HVAC system to provide air purification to every room in your home.
