Sources of Indoor Air Pollution“But my house is really clean,” you might cry. A clean house doesn’t mean it’s free from pollutants. You have control of some polluting substances, but not all. So, what are the causes of indoor air pollution, per the EPA?
- Combustion sources. These can release harmful byproducts like carbon monoxide and particulate matter. The sources include:
- Wood and coal heating and cooking appliances
- Commonly used home products. These can release many different chemicals, including volatile organic compounds. Sources of this type of pollution include:
- Cleaning supplies
- Paints, varnishes, caulk, etc.
- Air fresheners
- Building materials. Pollutants are released via degrading materials (e.g., asbestos fibers released from building insulation) or by new materials (e.g., chemical off-gassing from pressed wood products).
- Natural substances. These include things like radon, mold, and pet dander.
Air ScrubbersYou might not be familiar with air scrubbers, because they usually are used for industrial applications But, they’re available for your home and they can be portable, or an HVAC contractor can install a whole-home air scrubber that works with your current air conditioning and heating system.
Whole House Air ScrubberAn air scrubber attaches directly to the ductwork of your HVAC system. It removes air pollution, VOCs, surface contaminants, pet dander, odors and dust to provide a cleaner, healthier and more efficient home. Air scrubbers use proprietary light waves along with a specialized catalytic process to keep your home cleaner. And it doesn’t produce ozone, which is considered a pollutant. What is ozone? The EPA says that breathing ozone can cause a variety of health problems that include chest pain, coughing, throat irritation, and airway inflammation. Ozone also can reduce lung function and harm lung tissue, worsen bronchitis, emphysema, and asthma. The disadvantage? A whole house system only works if the heater or air conditioner is actually running. If no air is running through the system, the scrubber is not working. This being said, many have found relief from allergies and other problems even though it’s not continuously running.
Portable Air ScrubberPortable scrubbers are mostly used for industrial applications and extremely large areas, like a warehouse or commercial buildings, but you can buy smaller units made for household use. A portable air scrubber can be placed in any room where you know or suspect you have poor air quality. Air scrubbers use filters to help remove contaminants as the air is circulated through the unit. Several times every hour, the scrubber draws in the air contained and expels the same air, now free from some impurities. These portable scrubbers feature high-RPM motors, high-efficiency blowers, and an upright cabinet design. While each air scrubber unit is different, all units follow a similar process with multiple filters that remove 99.97% of airborne particles. If a HEPA filter is used in the unit, it is able to filter a considerable amount more than a regular filter. The HEPA filter will capture small particles such as mold, bacteria, asbestos, lead, dust and many other airborne contaminants. These portable scrubbers do a great job, but can be a bit noisy, and if you want to clean the air in your entire house, you’ll need one for each room
Air PurifiersLike air scrubbers, a contractor can install a whole-house system, but portable units are plentiful. Most portable air purifiers on the market will do the job, but here are some things you should consider:
- Where will you put the air purifier? You’ll need to choose the right size for the space.
- If you have specific health or home needs – like removing pet dander or cigarette smoke – look for an air purifier that's good at filtering out those specific pollutants.
- Compare Clean Air Delivery Rate (CADR) ratings, which show how well an air purifier filters specific pollutants.
- Choose one with a HEPA filter, which is the gold standard for indoor air purifiers.
- Pay attention to noise levels in product specs. Depending on where you're using it, you might want a quieter unit.
How to Choose the Right Air Purifier for Your Room SizeBefore you buy an air purifier, you need to figure out how much space you want the device to clean. Small desktop units aren't effective in large living spaces, and larger, heavy-duty air purifiers may be more than you need in your bedroom. You can find the best fit two ways:
- Look at "air changes per hour." This figure may be included in your air purifier's specs, and if it’s not, contact the manufacturer. This metric can help you understand how filtration works in real life, because a smaller air purifier could turn over the air in a 350-square-foot room eight times in an hour but manage just four air changes per hour in a 700-square-foot room.
- Compare CADR. According to the Association of Home Appliance Manufacturers, take the CADR rating and multiply this by 1.55 to get the room size that fits the unit. This is based on a ceiling height of 8 ft.
When to Call in ExpertsAir scrubbers and air purifiers are great ways to clean the indoor air pollution in your home, but if you have a fire, flood or other event that causes the release of pollutants or encourages mold growth, it’s time to call in the professionals.
