Air conditioners and air coolers

Since people spend approximately 90 percent of their time indoors, it’s important to make sure the inside air you breathe is safe and circulating, say experts with the U.S. Environmental Protection Agency (EPA) and the U.S. Consumer Product Safety Commission, which offer ways to identify air quality problems.

Hazardous indoor air quality can be caused by smoke and scents of cigarettes, cooking or household cleaning products that linger without proper ventilation.

High temperature and humidity levels can also increase concentrations of some pollutants, says the EPA.

The young, elderly and chronically ill, especially those suffering from respiratory or cardiovascular disease, are most susceptible to the effects of indoor air pollution, according to the agency.

Outdoor contaminants such as pollen, dander and bacteria can be brought into a home by family members or pets. And everyone’s aware of seasonal allergies.

Experts say if pollutants are in the air, close any openings you can — windows, outside doors, chimney flues — and cover cracks that let air leak in. Turn off anything that draws in outside air, like a fresh air system, dryer or portable air conditioner with a hose vented out a window.

You can run your A/C if it is not pulling air from outside. Set the fan to “on,” rather than “auto” to ensure the fan is constantly circulating and filtering air.

Avoid activities that increase indoor pollution such as smoking, burning candles or firewood in the fireplace, boiling a pot of water on the stove with essential oils, or using a vacuum that doesn’t have a high efficiency particulate arrestance (HEPA) filter, say EPA experts

Check your filters and change or clean them when dirty. Once a filter is full, it no longer traps particulates.

Health experts and others recommend using only HEPA filters, which force air through a fine mesh and trap particles in central heating, ventilation, cooling and air (HVAC) systems.
