There is a broad spectrum of health effects from poor indoor air quality. There may be no effect or significant effects for some individuals, as well as multiple variations in between. The effect on any one individual will be determined by the type of contaminant in the air, the quantity of contaminant, the duration of the exposure, and the individual's unique physiological response to the contaminant. Poor indoor air quality can be implicated in a variety of health related symptoms.

Indoor Air Quality (IAQ) refers to the effect, good or bad, of the contents of the air inside a structure, on its occupants. Usually, temperature (too hot or too cold), humidity (too dry or too damp), and air velocity (draftiness or motionlessness) are considered "comfort" rather than indoor air quality issues. Unless they are extreme, they may make someone unhappy, but they won't make a person ill.

Household cleansers, laundry detergents, air fresheners, aerosols, insecticides, insects, pet hair, dander, contents from litter boxes, cigarette smoke, food, dust (dust mites), people (dead skin, hair, perfume, etc.), carpet, construction materials, just to name a few. The best air purifier we have found, hands down, that reduces the most symptoms people experience with asthma is the IQair HealthPro or the IQair HealthProPlus.

No building is perfectly sealed and so the air inside ultimately originates outside. Air pollution present in the outdoor environment will therefore enter into the building as well. Generally, pollutants present in the outdoor environment are present at a somewhat lower concentration than outside (probably 10 to 90% in most cases). There are several reasons for this. Some pollutants are absorbed by materials in the building. Others deteriorate or react chemically and so disappear.

The usual clue is that people feel ill while inside the building, and the symptoms go away shortly after leaving the building, or sometimes, when away for the building for a period of time (as on weekends away from work, or a vacation). This doesn't necessarily work in cases of BRI (sections 2.3, 2.4), where it may take medical testing and investigation of the building to determine whether the building is the source of the problem.

Look over this FAQ. Find the material most related to what seems to be going on. In most cases there are suggestions as to things that can checked in to. Some of these can be checked by anyone; others require an expert (medical doctor, HVAC service company, IAQ investigator, etc.).

The air quality categories based on PSI and the general health effects associated with the different categories are summarized as follows: Mild aggravation of symptoms among susceptible persons i.e. those with underlying conditions such as chronic heart or lung ailments; transient symptoms of irritation e.g. eye irritation, sneezing or coughing in some of the healthy population.

Poor IAQ can be caused by many things such as: poorly designed HVAC systems, HVAC systems not being properly operated or maintained, not enough outside air being brought into the system, poor air circulation. It is important that IAQ complaints be documented and that appropriate professionals are used to determine the extent, if any, of the problem. Ignoring an IAQ problem will only make it worse.

Household cleansers, laundry detergents, air fresheners, aerosols, insecticides, insects, pet hair, dander, and litter boxes, cigarette smoke, food, dust (dust mites), people (dead skin, hair, perfume, etc.), carpet, construction materials, and anything moist can grow more. Additionally, items such as bedding/linens and furniture, even HVAC systems, can trap and collect contaminants.

Allergies; asthma; dry, itchy skin; irritated eyes, nose and throat; headaches; dizziness; fatigue. Poor indoor air quality has been linked to all of these medical conditions and symptoms. In fact, your indoor air can be five times more polluted than the air outside. The EPA ranks indoor air pollution as one of the top five environmental risks to public health.

The Environmental Protection Agency (EPA) has declared Indoor Air Quality (IAQ) the nation's worst environmental health problem, even worse than outdoor air pollution. A significant increase in asthma and hay fever corresponds to an increased level of allergens and irritants in our homes and offices as a result of poor Indoor Air Quality (IAQ).

The first step toward better indoor air is to identify the types of pollutants present in the home. The best way to do this is to schedule an in-home air-quality test. Routine cleaning and housekeeping helps reduce indoor air pollutants, but these simple fixes are not cure-alls. Some contaminants are so small that they may escape through the vacuum or never land on a surface.

Today’s homes are sealed tight to shelter us efficiently from the heat or cold and this results in low circulation of air and infrequent changes. Our indoor air contains minute particles such as dust mites, pet dander, pollen and mold spores that can cause health isues such as asthma, allergies and other respiratory difficulties. To add to this, many of today's cleaning products, furniture, carpets and building materials release chemicals, which are hazardous to health.

Keeping all students indoors does not happen very often. For example, during the winter of 2006-07, there were only 4 days at Hawthorne Elementary in Salt Lake City in which PM2.5 levels were above 90 ug/m3. In Ogden there were only 2 days in which PM2.5 levels were above 90 ug/m3.

Unfortunately, quite severe. The EPA has ranked indoor air pollution as the nation's worst environmental health problem, calling it 2 to 10 times worse than outdoor air pollution.

Yes. An all-electric heat pump system produces no products of combustion and therefore no indoor air pollutants are possible. Conventional gas and propane systems require chimneys to vent away harmful carbon monoxide and other dangerous gases.
