According to the EPA, the air in your home can be more than 5-times more polluted than the air you breathe when you are walking outside. There is a variety of reasons why that is: The most reasons are listed below:

Poor ventilation

Lack of proper ventilation makes air circulation impossible. Dirty air gets trapped inside your home while no fresh, clean air can come in. The result is a stale and stagnant environment full of harmful contaminants.

Indoor moisture and humidity levels

These issues are commonly caused by poor ventilation and not only affect your comfort but the air you breathe as well. High humidity levels create an ideal environment for contaminants (mold, mildew, bacteria and germs) to grow. Because of poor ventilation those contaminants are then released into your home instead of outside and can directly affect your well-being. On the other hand, low levels of moisture in the air can irritate your skin, give you a sore throat and cause other issues to your respiratory system.

A variety of air contaminants

Dust and pollen particles, pet dander, mold, bacteria and viruses, a variety of odors and possibly harmful chemicals (cleaning supplies, paints, cooking fumes, etc). Most of these contaminants are too small to see and can enter your home though open windows and doors, chimneys and fireplaces or can be carried in by you and your family.


Temperature imbalances in your home can affect your comfort on a daily basis. Uneven temperatures from room to room are usually a sign of an inefficient HVAC system. Regular checks by the homeowner (changing filter) and pre-season full-system tune-ups by an experienced HVAC technician can eliminate the majority of your temperature issues.


One of the most effective ways to improve the quality of your home’s air is to reduce the number of contaminants in it. You can do that in a number of ways. Regular HVAC system maintenance – by servicing your furnace and your air-conditioner unit on a yearly basis you can ensure that your HVAC system will be running at peak efficiency year-round. Proper operation results in cleaner air by removing the majority of all contaminants from your home and not allowing the growth of other new ones.

Use of additional air cleaning and treating equipment – There is a variety of equipment on the market today specifically designed to effectively address indoor air quality and comfort issues and in combination with a “healthy” HVAC system can give you the peace of mind you want.

That equipment includes:


Humidifiers are designed to add the appropriate amount of moisture to dry air and make your living conditions more comfortable. By increasing your air’s humidity, you can make your space feel warmer, you can reduce dry skin problems and unwanted static shocks, you can also save money on your energy bills, by not having to use your home’s heat as frequently.


Dehumidifiers are designed to remove moisture from indoor air that might feel sticky and uncomfortable. Dehumidifiers can help balance your home’s humidity levels and reduce the potential of mold and bacteria growth.

Air Cleaners/Purifiers

Air cleaners & purifiers are designed to attach to your furnace or air conditioner or function as stand-alone units. They can successfully capture and destroy contaminants, thus preventing them from getting re-circulated through your home over and over again.

Air Filters

Air filters are already a very important part of your furnace and air conditioner. They are designed to capture dirt, mold and other air pollutants and prevent them from getting distributed throughout your home. As a homeowner, changing those filters on a regular basis can make all the difference in the world.
