Where indoor air problems come from
Sources inside the building
EPA lists fuel-burning combustion appliances, tobacco products, building materials and furnishings, cleaning and hobby products, heating and cooling systems, humidifiers and excess moisture among the common sources of indoor air pollutants (EPA).
Appliances and products
EPA says unvented or malfunctioning appliances, and improperly used products, can release higher and sometimes dangerous levels of pollutants indoors (EPA).
Outside and ventilation
Outdoor sources such as radon, pesticides and outdoor air pollution can also affect indoor air, and EPA notes that inadequate ventilation can let pollutant levels rise (EPA).
What EPA says improves indoor air
This is EPA’s general guidance. It is not a description of what H&H’s services involve.
Source control
EPA says that usually the most effective way to improve indoor air quality is to eliminate individual sources of pollution, and that for most indoor air quality problems in the home, source control is the most effective solution (EPA).
Ventilation
Bringing in more outdoor air dilutes indoor pollutants. EPA lists opening windows and doors and running exhaust fans or mechanical systems, and advises caution where nearby outdoor sources, such as smoke or refuse, may add pollutants (EPA).
Air cleaners
EPA says how well an air cleaner works depends on how well it captures pollutants and how much air it moves. Some units remove particles well, but most table-top models do not, and air cleaners are generally not designed to remove gaseous pollutants (EPA).
If someone in the household has symptoms
What EPA lists
EPA lists eye, nose and throat irritation, headaches, dizziness and fatigue among the immediate effects of indoor air pollutants, and says the effects can include worsened asthma symptoms (EPA).
Notice the pattern
EPA suggests noting when and where symptoms occur, and says that if symptoms fade when a person leaves an area, indoor sources should be investigated (EPA).
Talk to a healthcare professional
Talk with a healthcare professional about symptoms. H&H’s indoor air quality services are not medical services.
This page is general information. It is not medical advice, and no air quality service can promise a health outcome.
Air and moisture after water damage
Humidity
EPA suggests keeping indoor humidity below 60 percent, ideally between 30 and 50 percent (EPA).
Generators
If the power is out, never run a fuel-powered generator inside a home or garage. EPA says to keep generators outside and at least 20 feet from buildings (EPA).
Ducts that were underwater
Do not run the furnace blower or central air if the ducts were underwater. Have a professional inspect heating and ventilation systems first (NYS Department of Health).
H&H’s water damage restoration deals with the water, and mold services covers mold assessment and mold remediation.
