Indoor Air Quality Products

Home is the one place you should always be able to feel safe, but there could easily be danger lurking in your Illinois or Indiana house. It’s called bad air as in unhealthy indoor air quality. In fact, health experts say indoor air is often much unhealthier than outside air.

How is that possible?

Despite great strides in the clean air movement, Merts Heating & Air Conditioning reminds you Illinois & Indiana are densely populated urban areas. Cars, trucks, buses, trains, and factories can all contribute to outdoor air pollution. Eventually anything that’s polluting the outdoor air makes it indoors. Once inside those pollutants combine with a host of indoor contaminants like:

  • Pet dander
  • Dust mites
  • Mold
  • Volatile organic compounds (paints, stains, paint strippers, aerosol sprays)

The combination of outdoor and indoor pollutants means the year round level of allergens can be 10 to 100 times greater indoors than outdoors, leading to poor indoor air quality. It should come as no surprise this can create a whole series of problems.

Indoor Air Quality Far reaching health effects

Health experts paint a scary picture of what constant exposure to indoor air pollution can do. 

  • Coughing
  • Breathing difficulties
  • Sore throats
  • Watery or itchy eyes
  • Asthma attacks
  • Headaches

These effects are made all the worse because of constant exposure. Between work and home most people spend 90% of their time indoors.

Best ways to fight back

Whether your home is in Matteson, Park Forest, Chicago Heights, Glenwood, or Lynwood, IL, there are ways to improve your indoor air quality.


When the weather allows, open some windows. This will exchange the air that’s in the home and lower the concentration of indoor air pollutants. NOTE: Do not do this if there are outdoor air quality warnings in effect.


Make sure HVAC filters are changed regularly. Depending on the type of filter this is usually every 30 to 90 days. If you live in a dusty location or have multiple pets the filters should be changed more often. Good quality filters will remove more pollutants from the air. Check with Merts if you have any questions about which filter is best for your heating & cooling systems.


Filters are designed ONLY to trap particles, while air purifiers are able to kill some bacteria and viruses. They can do this using electrostatic technology, activated charcoal, or ultraviolet lights. Unlike filters, air purification systems are also capable of removing odors from the air.
