How Poor IAQ Is Making You Sick

Originally published January 2017, updated March 2020.

We spend a lot of time thinking about how Houston, Texas, outdoor allergens make us sick. But not everything causing your allergies is found outdoors. In fact, many of your allergies may stem from poor indoor air quality (IAQ.) The culprits of bad IAQ are invisible, so it takes research and preventative measures to be sure your home’s air is as clean as it can be.

VOCs in Your IAQ

Volatile Organic Compounds, known as VOCs, are chemical compounds found in many home products. They contain toxic molecules that easily become gaseous, like formaldehyde, which is why they’re so bad for IAQ. You can find VOCs in cleaning products, paint, and even shower curtains. VOCs can worsen asthma symptoms and cause flu-like symptoms in otherwise healthy individuals.


Did you know many people are allergic to cockroaches? When pests die in our homes in places we don’t know about, their carapaces disintegrate into particles small enough to infiltrate the air. Some of your indoor allergies may not have to do with pollen from outside getting in, but from pests inside.

Biologic Particulates, Viruses, and Bacteria

There are many types of allergens, viruses and bacteria that that can get into our homes, some of which are more toxic or problematic than others. Biologic particulates and viruses can cause the most health problems. Biologic particulates love areas of high humidity, especially if there’s a leak or a wet spot somewhere. The spores then release into the air and cause an array of respiratory problems.

Indoor Air Quality Solutions

How can you rectify these problems? Some solutions you can do yourself involve using organic cleaners and doing a thorough deep clean of your home frequently. Other solutions we’re happy to help you with. As a Factory Authorized Carrier Dealer, Davis AC has access to the best IAQ products, including dehumidifiers and air purifiers.

The Infinity® Air Purifier works quietly in-line with your HVAC system to make the air you breathe healthier. It uses a technology called, Captures and Kills™, that traps up to 95% of pathogens and then uses an electrical charge to kill or inactivate them. As your home’s air is circulated through this system, pollen, bacteria, viruses and other pollutants are trapped in the filter and then rendered inert. Independent testing has proven the Infinity’s air purification system effective against 13 pathogens.

Even performing simple HVAC maintenance, like duct cleaning, will help with your IAQ. Don’t hesitate to call for more information about our indoor air quality products.
