When you buy a filter, you should look for a higher efficiency such as pleated rather than a higher arrestance such as fiberglass.  Here is the difference between the two:

• The efficiency of an air filter removes microscopic particles such as dust, dust mites, pollen, mold, bacteria, and smoke.
• The arrestance of an air filter removes larger particles such as dirt, lint, hair, and dust.
• All filters come in custom made sizes.

Why filter the air?

To protect your health

The air we breathe is a sea of particles too small to be seen with the naked eye.  These particles are known as dust, pollen, bacteria, mold spores, mineral dust, animal hair, and dander.  They are harmful pollutants because they act as carriers for viruses and work their way into our clothes, furniture, computers, and lungs.  Breathing these particles can lead to minor allergies or more complicated respiratory problems.

To $ave Money

Your heating and air conditioning system is most efficient when the air flow is working at its peak performance. For example, if your A/C coil or ductwork is clogged, the airflow is diminished, which means the system must run longer to heat or cool the same amount of space.  If you filter the air before it enters your A/C system, your equipment will be able to perform at its peak capacity.  If you neglect the filter, the A/C coil will get so clogged with dirt that the A/C evaporator coil will freeze into a solid block of ice.

To repair this problem, a service technician will have to take apart and clean your entire A/C system, which will be very costly and labor intensive.  Finding the right filter is just as important, so start protecting your health and your money by calling the experts at Air Conditioning Excellence at
