Indoor Air Quality

There are several indoor air quality sensors on the market right now that can detect (and document over time) the quality of air within your house. PM2.5 levels (small dust particles and other allergens in the air that you breathe), VOCs (Volatile Organic Compounds - like chemical pollutants), temperature and humidity are commonly measured by these instruments (for mold). These gadgets generally cost between $150 and $250.

Poor indoor air quality can cause an array of health issues that range from aggravating to life-threatening. Itchy eyes, a runny nose, sneezing, coughing, dizziness and weariness are common symptoms. If any of your family members have asthma, poor indoor air quality can also increase their odds of having asthma symptoms including wheezing, trouble breathing, coughing and chest tightness. 

First, replace your AC filters on a regular basis, or get an air conditioning service plan that includes a filter change – especially if you have allergies or live in a polluted metropolitan area. Examine your air ducts as well. Dust, dander and even mold can collect in your ducts over time, lowering overall air quality. Hire an expert to ensure that your ducts are flowing clean, fresh air. Also, control the humidity in the home. Mold and mildew thrive in humid and damp environments, causing respiratory disorders such as allergies and asthma. With a few strategically positioned dehumidifiers, you can reduce the moisture in the air and prevent the formation of bothersome molds.

For individuals with asthma, an effective air purifier should include a HEPA filter to capture fine allergens, an activated carbon filter for odors and chemicals, and be appropriately sized for the room. Opt for models with certifications like those from the Asthma and Allergy Foundation of America, ensuring they are efficient in allergen removal. It’s essential to choose an "ozone-free" purifier to avoid lung irritation. Features such as smart sensors for air quality monitoring can be beneficial. Brands like Honeywell, Dyson, and Levoit are frequently recommended for their efficiency in filtering out pollutants and maintaining a healthy indoor environment. Always verify that the air purifier’s features align with the needs of an asthma sufferer.

The frequency of cleaning or replacing HVAC filters depends on various factors, including the type of filter, the presence of pets, and household conditions. Generally, disposable filters should be replaced every 1-3 months. Homes with pets, smokers, or allergy sufferers may require more frequent changes, possibly monthly. Washable filters should be cleaned every 1-2 months. Regular maintenance ensures optimal airflow, improves indoor air quality, and enhances system efficiency. Always refer to the manufacturer's recommendations for your specific HVAC system.

Yes, scented candles and air fresheners can negatively affect indoor air quality. They often release volatile organic compounds (VOCs) and other harmful chemicals into the air, which can cause respiratory issues, allergies, and other health problems. Burning candles also produces soot and particulate matter, further degrading air quality. To maintain a healthier indoor environment, consider using natural alternatives such as essential oils or houseplants for fragrance. Always ensure proper ventilation when using any scented products.

Humidity plays a significant role in indoor air quality. When humidity levels are too high, it can promote the growth of mold and dust mites, which negatively impact air quality and cause health issues such as allergies and respiratory problems. On the other hand, if the humidity is too low, it can lead to dry skin, irritation of the respiratory tract, and increased levels of airborne dust. Maintaining an optimal humidity level between 30% and 50% can help improve indoor air quality and comfort.
