Where Do Air Quality Problems Come From?

Sick woman blowing her nosePoor indoor air quality is not a unique problem, though it is a relatively new one. In recent decades, home construction has become tighter. This allows your HVAC systems to function as efficiently as possible, without air loss or unnecessary energy waste. This is great news for your wallet, but not so much for your indoor air quality. If air cannot get out of your home, that means neither can airborne contaminants or humidity.

When most homeowners hear the term “bad indoor air quality,” they think it’s just an inconvenience, maybe even mildly uncomfortable. However, poor indoor air quality can actually have a considerable negative impact on your health and comfort throughout the years. If you’re unsure of what to do about your indoor air quality, keep reading!

What to Know about Airborne Contaminants

Airborne contaminants are easily the most common cause of poor indoor air quality. This may include particles like dust, pollen, dander, viruses, bacteria, mold sports, and more. These aren’t all immediately dangerous to a relatively healthy person, however breathing them in over a long period of time can cause a number of ailments. Additionally, someone who already suffers from indoor allergies or asthma can suffer.

“But, doesn’t my HVAC system’s air filter protect against this?”

Well, no. We understand why you might assume something called an “air filter” would do this, however that is not its job. The standard air filter that comes with your HVAC installation is there to protect the inside components of that HVAC system from dust and other debris that can impact the system’s ability to operate. It is not there to protect your indoor air quality.

The best way to defend against airborne contaminants is with the installation of a high efficiency air filtration system or air purifier in your home. These systems are developed to effectively remove contaminants from your air supply, with the methods used determined by exactly which system you choose. That being said, we highly recommend that you consult with a trained and experienced indoor air quality specialist to determine what’s best for you and your home.

What to Know about Humidity

With your airborne contaminants managed, it’s time to look at the level of relative humidity in your home. The ideal level is between 30-50%. Anything lower than that is considered too dry and can cause a number of health issues as well as property damage. Anything higher than 50% means you have excessive moisture in the home that needs to be dealt with. This is a common issue this time of year, so it’s the one we’ll talk about here.

Excessive humidity can cause a number of problems. For one, it encourages the growth of mold and mildew both in your ductwork and your home. For even the healthiest person, exposure to these contaminants can cause issues. Plus, mold growth actually damages your property, which can lead to costly repairs and renovations.
