Having said that, the obvious exception is when cigarette, pipe or cigar smoking occurs on a regular basis. Now the pollution can’t be missed, you can see it and you can smell it. The health concerns regarding smoking are well known and possibly beaten to death, so we won’t get in to that. Not so obvious is the health impact of dirty interior air when we don’t notice it. Medical experts have concluded that symptoms ranging from headaches, asthma, bronchitis, allergies and cancer among others, may likely be attributed to polluted interior air.

The next reason to use a furnace filter or air conditioning filter is to keep your heating and cooling system operating as it was designed and to prolong its life. For an air conditioning unit to operate at its peak efficiency it needs to be kept clean. The evaporator is the component in your system in which the air passes directly over and is cooled and returned to your living space. The surfaces of the evaporator are normally very cold and therefore wet with condensation. The moisture in the air condensates on the evaporator and subsequently drains to the exterior of the building. Imagine blowing dirty air across the cold wet surfaces of the evaporator. How long do you think it takes for the dirt to completely cover this wet surface? Once dirty, the evaporator loses efficiency and may begin to support mold and bacteria growth, after all it is a dark moist environment.

The last reason for using an air conditioning filter and furnace filter is to help keep your house clean. Look at it this way, every time your air conditioner or furnace runs it is like someone is vacuuming the air of dust, dirt or worse. All of this for only a couple bucks per month, seems like an obvious choice, your air must be filtered. What may not be obvious is which furnace filter and air conditioning filters should be used, we will try to help with that decision.

There are many different types of furnace air filters available today.  The two main types are throw away and the other are washable. Washable furnace air filters won’t last forever but most people could get several years of use from them with regular cleaning. Then again cleaning these filters is a pain and if it is cold outside it can be quite inconvenient. We feel most people will find using a disposal filter is both easier and quicker and in the long run a better option.

Selecting the correct filter will include looking at the MERV rating.
