Stop and think: how clean is the air you breathe inside your home?

A recent report by the Environmental Protection Agency revealed that the air quality inside the average home is five times worse (full of dander, pollen, dust mites, and other irritants) than the air outside! Keep your home and family healthy with air purification solutions customized and installed by your trusted WM Henderson team.

Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially related to building occupants’ health and comfort. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns.


Indoor dust and pet dander allergens

Dust mites are microscopic bugs that live in carpet, bedding, upholstery, stuffed toys, and bedding. These bugs are invisible to the human eye but can majorly impact health. This is especially true for those already at risk, like the young, elderly, or those with allergies or asthma/ Relatively minor effects include coughing, wheezing, and discomfort. At the same time, more severe implications can require medication or even hospitalization.

Dander (dead skin cells sloughed off an animal’s coat) is the most common source of pet allergies. Pet dander clings to surfaces and makes its way into household cracks and crevices. Unfortunately, dander can linger for months in carpets, furniture, and even bedding! The result includes a variety of health issues for allergy sufferers.

Frequent cleaning at home – including vacuuming, frequent bedding changes, and wiping down surfaces – helps keep these pollutants at bay. Use a vacuum cleaner with a HEPA filter to reduce dust and pet dander concentrations in your home. A HEPA filter can also eliminate other toxins, including lead.

Volatile Organic Compounds (VOCs)

Volatile Organic Compounds (VOCs) are toxic airborne chemicals emitted as gases from certain solids or liquids. Top sources of VOCs in the home include paints, aerosol sprays, and air fresheners, pesticides, dry-cleaned clothing, and cleansers. Once airborne, these particles pose short and long-term health effects. According to the EPA, VOCs often cause eye, nose, throat irritation, nausea, and damage to the liver, kidney, and central nervous system.

Bacteria, Germs, and Viruses

Poor indoor air quality can increase the risk of spreading highly contagious viruses like the cold and flu. More severe viruses, such as Coronavirus (COVID-19), are also a threat. Viruses are microscopic pathogens that need hosts to thrive. Once a virus enters the body, it begins to hijack healthy cells and reproduce at a significant pace.

Bacteria or germs thrive in enclosed spaces and spread quickly through the air. Most bacteria are harmless. However, some strains of bacteria produce toxins that can kill cells and damage the immune system.

Indoor air pollutants may cause serious health concerns, such as:

  • Nausea
  • Dizziness
  • Fatigue
  • Sneezing
  • Coughing
  • Eye and skin irritations
  • Congestion
  • Headaches
  • Allergic reactions
  • Respiratory tract infections
  • Asthma

The EPA states that indoor air is one of the top five environmental health risks of our time. In fact, indoor air has been found to contain up to 60 times more pollutants than outdoor air. A recent study by the American College of Allergists & Asthma states that polluted indoor air is the root cause of 40% – 50% of all illnesses.


Eliminating individual sources of pollution in the home can reduce indoor air pollutant concentrations and reduce emissions.

Harmful pollutants may come from faulty appliance emissions, such as stoves or furnaces. Two out of three indoor air quality issues involve the poor performance and improper functioning of your HVAC (Heating Ventilation Air Conditioning) system. That’s why it’s crucial for a thoroughly trained technician to evaluate your home equipment annually.

Improving your indoor air quality can begin with tests for key pollutants known to impact health.


Homes built before 1978 can benefit from a lead test, as most indoor and outdoor paints were lead-based before that time. Lead dust brought in from outside sources may also affect air quality in newer homes. Lead dust can be especially detrimental to children’s health in the home and may damage the brain, central nervous system, and kidneys.

Use a vacuum cleaner with a HEPA filter to reduce concentrations of lead in your home. A HEPA filter can also eliminate toxins. The Environmental Protection Agency offers practical suggestions on how to make your home lead-safe.


Homeowners are encouraged to test for radon. Radon is a colorless, odorless, radioactive gas that typically moves up through the ground and into living spaces through cracks, gaps, or holes in the foundation. However, even airtight homes can potentially have it, and granite countertops have also been linked to radon.


Radon gas is prevalent in Eastern and Central Pennsylvania due to uranium deposits in the rock strata. Uranium off-gases radon as a by-product of mining activities. The good news is that in-home radon testing is easy, reasonably inexpensive, and takes only a few minutes to complete. A radon test is highly recommended, as radon is the second leading cause of cancer in the United States according to the American Lung Association.

In some cases, radon testing is required by certain lending institutions before the transfer of a property. Rest assured that with proper remediation equipment, even high radon levels can be reduced to acceptable levels.

Carbon monoxide (CO)  is known as “The Silent Killer” in your home. Like radon, carbon monoxide is a toxic odorless, tasteless and colorless gas. A buildup of CO in the home can lead to carbon monoxide poisoning or, in extreme cases, death. CO can come from any device that burns fuel such as your furnace, water heater, stove, and dryer if they are not in good working condition or have not been installed with proper ventilation.


Symptoms of someone experiencing CO poisoning can range from shortness of breath, mild nausea and mild headaches to dizziness, mental confusion, severe headaches and even death.

Since carbon monoxide does not have characteristics such as odor to alert you, the best way to keep your family aware of unsafe levels is to install carbon monoxide detectors throughout the house. A carbon monoxide alarm constantly samples the air, monitors for the presence of CO and sounds an alarm when CO is detected at dangerous levels.


Testing for mold spores in the air can be as simple as purchasing a mold test kit. Dust mites and mold love moisture. Keeping a healthy level of humidity at around 30%-50% will help keep them and other allergens under control.


Using a dehumidifier and air conditioner during summer months will help reduce moisture in indoor air and effectively control allergens.  An efficient air conditioner will also lower indoor pollen count. As a side note, modern high-efficiency central air conditioning systems have intelligent thermostats that tell fans to ramp up or down, depending on particular needs, thus controlling humidity levels better than ever.

Make sure your leaky plumbing gets repaired to prevent mold. From small portable table-top air cleaners to whole-house systems, there are many tools to help make your IAQ healthier.

A WM Henderson technician can service your furnace annually to prevent problems, such as carbon monoxide poisoning.


Although ventilation improvements and regularly changing your air filters can improve your home air quality, there’s still a wide array of risk factors to consider. Our certified and licensed HVAC technicians are extensively trained to assess poor air quality and offer customized options to restore the health of your home and the quality of your air. Adding air purification technologies, Lennox PureAir™ and Phenomenal Aire Cold Plasma Generator (CPG) to your HVAC system is the first step in evaluating and controlling your indoor air quality.


Lennox PureAir™ pairs the germ-killing power of UV light with MERV16 filtration to eliminate odors, mold spores, and more from the air you breathe at home.
