Most people think of dirty air and they think of outdoor pollution caused by vehicles, machinery, buildings, etc. The truth is that your indoor air quality might actually be more harmful to your health than the outdoor air. Indoor air quality can negatively contribute to many aspects of your health including allergies and asthma. Let’s take a closer look at different ways that dirty indoor air can actually affect you on a day-to-day basis.

What are the Culprits?

There are a number of small particulates that can be in your indoor air at any given moment. Dander from your pets can accumulate all over your home and be passed through your HVAC system. Dust is a common irritant in almost every home. Mold spores can grow because of too much humidity in the air of your living space. Outdoor pollutants can make their way indoors. If you have recently had a pest infestation of some sort in your home then you could actually be breathing in their waste products. There are a number of products in your home that contain chemicals that can be hazardous to your health if you breathe them in. Take the appropriate steps to make sure that your indoor air is clean and safe for everyone that currently lives under your roof.


If you suffer from allergies then your indoor air quality is something very important to think about. If you breathe in these irritants it will cause inflammation in your airways and sinuses. This leads to an increase in allergic symptoms like a runny nose, sore throat, cough, itchy eyes, and an Itchy throat.

Keep in mind that you don’t have to be allergic to something in order for it to irritate you. Many people are not allergic to cats but if they touch a cat, the dander will irritate their skin and cause a reaction because it is a foreign irritant. Some people find that their seasonal allergies are worse when their indoor air is filled with other irritants that only make the problem worse. The less particulates that you have in your indoor air the better your allergies will be throughout the year.


Bacteria and viruses can easily be passed around the indoor air of your home. If someone in your family is sick then you could potentially become ill just from the regular circulation of indoor air. Nobody wants to be sick so take the necessary steps to increase the quality of your indoor air. You should change your furnace filter every thirty days or so (depending on the filter). You can also have an air purification unit installed onto your furnace in order to further clean the air that you breathe. Many of these units remove bacteria and viruses from the air inside of your home.


Asthma is a condition that should be taken very seriously. It can be extremely scary to suffer from an asthma attack. Because of this, people who have asthma take special precautions to avoid the irritants that trigger an attack for them. Poor indoor air quality can cause the airways to be inflamed more than they should be. This can put a person at a higher risk of developing an asthma attack if they come into contact with something else that typically bothers them. Having healthy indoor air can greatly reduce the amount of asthma attacks that you will experience each month.

Sure that layer of smog that perpetually sits over your city is unhealthy. So is breathing in the smoke from a nearby fire or smelling the exhaust from a vehicle that is driving in front of you. Don’t underestimate the quality of the air inside of your home. This is where you spend a good deal of your time each day. While you sleep and your body heals itself, your indoor air quality needs to be good in order for your body to function optimally. If you have questions about your indoor air quality or would like to have your air tested, you can contact a reputable HVAC professional or indoor air specialist in your area in order to find out more information.
