Controlling Indoor Air Pollution

The three most common approaches to reducing indoor air pollution, in order of effectiveness, are:

  1. 源控制: Eliminate or control the sources of pollution;
  2. 通风: Dilute and exhaust pollutants through 室外空气通风, and
  3. 空气净化: Remove pollutants through proven 空气净化 methods.

Of the three, the first approach -- 源控制 -- is the most effective. This involves minimizing the use of products and materials that cause indoor pollution, employing good hygiene practices to minimize biological contaminants (including the control of humidity and moisture, and occasional cleaning and disinfection of wet or moist surfaces), and using good housekeeping practices to control particles.

第二种方法—— 室外空气通风 -- is also effective and commonly employed. 通风 methods include installing an exhaust fan close to the source of contaminants, increasing outdoor air flows in mechanical ventilation systems, 和打开窗户, especially when pollutant sources are in use.

第三种方法—— 空气净化 -- is not generally regarded as sufficient in itself, but is sometimes used to supplement 源控制 and ventilation. 空气过滤器, electronic particle air cleaners, and ionizers are often used to remove airborne particles, and gas adsorbing material is sometimes used to remove gaseous contaminants when 源控制 and ventilation are inadequate.

三个基本策略

源控制

通常, the most effective way to improve indoor air quality is to eliminate inpidual sources of pollution or to reduce their emissions. 有消息, like those that contain asbestos, can be sealed or enclosed; others, 像燃气灶具, can be adjusted to decrease the amount of emissions. 在许多情况下, 源控制 is also a more cost-efficient approach to protecting indoor air quality than increasing ventilation because increasing ventilation can increase energy costs. Specific sources of indoor air pollution in your home are listed later in this section.

通风 Improvements

Another approach to lowering the concentrations of indoor air pollutants in your home is to increase the amount of outdoor air coming indoors. Most home heating and cooling systems, including forced air heating systems, do not mechanically bring fresh air into the house. Opening windows and doors, operating window or attic fans, when the weather permits, or running a window air conditioner with the vent control open increases the outdoor ventilation rate. Local bathroom or kitchen fans that exhaust outdoors remove contaminants directly from the room where the fan is located and also increase the 室外空气通风 rate.

It is particularly important to take as many of these steps as possible while you are involved in short-term activities that can generate high levels of pollutants--for example, 绘画, 油漆剥离, heating with kerosene heaters, 烹饪, or engaging in maintenance and hobby activities such as welding, 焊接, 或砂光. You might also choose to do some of these activities outdoors if you can and if weather permits.

Advanced designs of new homes are starting to feature mechanical systems that bring outdoor air into the home. Some of these designs include energy-efficient heat recovery ventilators (also known as air-to-air heat exchangers).

空气清洁剂

There are many types and sizes of air cleaners on the market, ranging from relatively inexpensive table-top models to sophisticated and expensive whole-house systems. Some air cleaners are highly effective at particle removal, 而其他的, including most table-top models, 就不那么重要了. Air cleaners are generally not designed to remove gaseous pollutants.

The effectiveness of an air cleaner depends on how well it collects pollutants from indoor air (expressed as a percentage efficiency rate) and how much air it draws through the cleaning or filtering element (expressed in cubic feet per minute). A very efficient collector with a low air-circulation rate will not be effective, nor will a cleaner with a high air-circulation rate but a less efficient collector. The long-term performance of any air cleaner depends on maintaining it according to the manufacturer's directions.

Another important factor in determining the effectiveness of an air cleaner is the strength of the pollutant source. 桌面空气清洁剂, 特别是, may not remove satisfactory amounts of pollutants from strong nearby sources. People with a sensitivity to particular sources may find that air cleaners are helpful only in conjunction with concerted efforts to remove the source.

在过去的几年里, there has been some publicity suggesting that houseplants have been shown to reduce levels of some chemicals in laboratory experiments. There is currently no evidence, 然而, that a reasonable number of houseplants remove significant quantities of pollutants in homes and offices. Indoor houseplants should not be over-watered because overly damp soil may promote the growth of microorganisms which can affect allergic individuals.

目前, EPA does not recommend using air cleaners to reduce levels of radon and its decay products. The effectiveness of these devices is uncertain because they only partially remove the radon decay products and do not diminish the amount of radon entering the home. EPA plans to do additional research on whether air cleaners are, 或可能成为, a reliable means of reducing the health risk from radon.

For most indoor air quality problems in the home, 源控制 is the most effective solution. This section takes a source-by-source look at the most common indoor air pollutants, their potential health effects, and ways to reduce levels in the home.
