The American Society of Heating, Refrigerating, and Air-Conditioning Engineers recommends a ventilation rate of 0.35 ach for new homes, and some new homes are built to even tighter specifications. Particular care should be given in such homes to preventing the build-up of indoor air pollutants to high levels. Express your concerns about indoor air quality to your architect or builder and enlist his or her cooperation in taking measures to provide good indoor air quality. Talk both about purchasing building materials and furnishings that are low-emitting and about providing an adequate amount of ventilation. Both the active and inert ingredients in pesticides can be organic compounds; therefore, both could add to the levels of airborne organics inside homes. Perchloroethylene is the chemical most widely used in dry cleaning.
If using cool mist or ultrasonic humidifiers, clean appliances according to manufacturer's instructions and refill with fresh water daily. EPA has recently published,"Should You Have the Air Ducts in Your Home Cleaned?"EPA-402-K , October 1997. This document is intended to help consumers answer this often confusing question. The relative importance of any single source depends on how much of a given pollutant it emits and how hazardous those emissions are.
ways to improve indoor air quality and reduce air pollution in your home.
For this reason, it is important to pay attention to the time and place the symptoms occur. If the symptoms fade or go away when a person is away from the home and return when the person returns, an effort should be made to identify indoor air sources that may be possible causes. Some effects may be made worse by an inadequate supply of outdoor air or from the heating, cooling, or humidity conditions prevalent in the home.
As a result, people who have noticed only mild allergic reactions, or no reactions at all, may suddenly find themselves very sensitive to particular allergens. Environmental tobacco smoke is the mixture of smoke that comes from the burning end of a cigarette, pipe, or cigar, and smoke exhaled by the smoker. It is a complex mixture of over 4,000 compounds, more than 40 of which are known to cause cancer in humans or animals and many of which are strong irritants. ETS is often referred to as "secondhand smoke" and exposure to ETS is often called "passive smoking." Because this job requires some complex cleaning equipment, it's best to leave this job to a professional. In the meantime, be sure to clean and dust all your registers and grilles.
ENVIRONMENTAL TOBACCO SMOKE (ETS)
The results can dramatically improve indoor air quality and help alleviate allergy and asthma triggers. This is an ideal add-on product for pet owners and those who suffer from seasonal allergies. According to a recent survey, 75 percent of U.S. households used at least onepesticideproduct indoors during the past year. Another study suggests that 80 percent of most people's exposure to pesticides occurs indoors and that measurable levels of up to a dozen pesticides have been found in the air inside homes.
The data summarized in this website come from the EPA's Air Quality System Data Mart. The AQS Data Mart contains outdoor air pollution data collected by EPA, state, local, and tribal air pollution control agencies from thousands of monitors. AirCompare maps provide information for counties that monitored outdoor air quality in the last five years and tailor that information for groups more likely to be affected by different levels of pollution. If you’re having constant problems with allergies, you’re likely allergic to your indoor air and you should consider investing in an air purifier!

Mechanical ventilation systems in large buildings are designed and operated not only to heat and cool the air, but also to draw in and circulate outdoor air. If they are poorly designed, operated, or maintained, however, ventilation systems can contribute to indoor air problems in several ways. Choose building materials and furnishings that will keep indoor air pollution to a minimum.
First, change your air filters out every 3 months to keep pollutants from building up in the air. There are UV filters, HEPA filters, and ionic purifiers, all of which will improve the air quality in your home. You can also use a carbon-activated filter if your main issue is with lingering odors in your home. If you are buying or selling a home, often testing the air for pollutants is a contingency of the loan you will be applying for. This is especially true in regions that have high levels of air pollution due to industry or even natural causes .

One hedge against poor air quality’s health risks is to live in an area with relatively clean air. Check out our guide to cities with the best air qualityif you’re considering moving to improve the quality of the air you breathe. And growing awareness that high CO2 levels can impair brain function has also been driving interest in the use of CO2 monitors recently, to help ensure that crowded spaces like classrooms and offices have enough ventilation. It makes sense that CO2 would build up in places where many people congregate.
Some of these designs include energy-efficient heat recovery ventilators (also known as air-to-air heat exchangers). If you work in construction, demolition, painting, with batteries, in a radiator repair shop or lead factory, or your hobby involves lead, you may unknowingly bring lead into your home on your hands or clothes. Soil very close to homes may be contaminated from lead paint on the outside of the building. Soil by roads and highways may be contaminated from years of exhaust fumes from cars and trucks that used leaded gas. If you work with lead in your job or a hobby, change your clothes before you go home and wash these clothes separately. Encourage your children to play in sand and grassy areas instead of dirt which sticks to fingers and toys.
Find out if your local government or any organization in your community sponsors special days for the collection of toxic household wastes. If such days are available, use them to dispose of the unwanted containers safely. If no such collection days are available, think about organizing one. Some biological contaminants trigger allergic reactions, including hypersensitivity pneumonitis, allergic rhinitis, and some types of asthma.
Some building materials, such as paints and paint strippers, can release VOCs . These chemical fumes can cause unpleasant symptoms, like irritation in your eyes, nose, and throat, as well as more serious health problems, such as liver or kidney damage. Radon is a radioactive gas that occurs naturally as uranium breaks down.
If you're experiencing symptoms you suspect are related to indoor air quality, getting an air quality monitor is an inexpensive way to pinpoint the problem. By monitoring levels of indoor air pollution, you can take steps to get fresh air back into your home, and hopefully, a little peace of mind with it. AirCompare provides information based on the five outdoor air pollutants that are part of the Air Quality Index - carbon monoxide, nitrogen dioxide, ozone, particulate matter, and sulfur dioxide. AirCompare does not account for pollen, mold, air toxics or indoor air quality conditions. Contact state or local air quality agencies for additional information. In the last several years, a growing body of scientific evidence has indicated that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities.
