When we think of “air pollution” we usually think of smog, factory smoke and auto emissions, not something inside our own homes. However, environmental research shows that the quality of air inside our homes and offices is up to five times more polluted than outdoor air! This is even if your furnace or air conditioner has not been repaired. The EPA reports that Indoor Air Quality is among the top five health risks.

Because most of us spend up to 90% of our time indoors, we need to look at what we can do to improve the air we breathe. Fortunately, treatment and prevention of indoor air pollutants are easy and economical.

Businesses in Platte City and St. Joseph that run their air conditioner or

furnace all summer long need to do more for their employees to improve the air they breathe. The indoor air in Missouri is no better or worse than the air in New .

If possible, control what comes inside that might contaminate the air. The type of insulation and paint you choose, your pets, and smoking are some of the things you can easily control. After that, Indoor Air Quality (IAQ) is primary affected by filtration, the level of humidity in the home, and the duct work the furnace and air conditioner use.

Air Filtration

Many people choose to add high efficiency filtration for their air conditioner/furnace. Good filters will get pollen, mold spores, and dust. It allows many people to breathe more freely in winter and summer. Additionally, you will be dusting less with a good filter controlling the air that runs through  your heating and cooling equipment.

A MERV rating is an industry standard that measures the overall effectiveness of the filter. A filter with a MERV rating between 9 and 12 are a very good choice for home owners that want to control dust. Dirty filters will have a negative effect on performance, so do change them when recommended. People in Weston, MO with hay fever should definitely have a high MERV filter on their air conditioner in August.


Two types of humidity issues may affect the comfort in your home: insufficient or excess moisture. Low moisture can cause dry nasal passages, increased respiratory problems and excessive static electricity in clothing and carpets.
Typical corrections for this situation are humidifiers and vaporizers, which add moisture to the air when it’s too dry. They can be free standing or be attached to your furnace and air conditioning equipment.

Excessive air moisture is a more complex issue, but still solvable. It can cause a number of undesirable conditions, some of which are obvious and others that are more hidden. If you have any of the following, you may have high humidity in your home:
• Damp spots on ceilings or inner surfaces of exterior walls.
• Mold or mildew growth on walls and ceilings.
• Peeling or blistering of exterior paint.

A de-humidifier is the solution, and can be free standing or integrated into your HVAC equipment.


Airborne contaminants like dust, dirt and allergens are drawn into air ducts and through the air return every time the heating and cooling system kicks on. Over time, this causes a build up or contaminants inside the air ducts, creating a fertile breeding ground for mold, bacteria, fungi and other microbes.

Air filtration is not enough to eliminate this build up. Two common solutions are cleaning the ducts and an ultra violet light to kill mold spores or anything growing in ductwork. All operating rooms and hospitals have some version of an ultra violet light. It will kill anything that passes through it.
