Choosing a filter

Filtration is especially important in HVAC system because your indoor air is up to 5 times more polluted than outside air! Why? Any pollution and contaminants that are in the home stay in the home. Newer homes that are very tightly constructed are even more susceptible to this. Fortunately, there is a solution. The heating and cooling system’s duct work pulls all of the air in the home through the return a certain amount of times per hour depending upon your system design. As long as the fan is operating, it is cycling air through the filter. We will go over the different types of filters, how often you should replace them, and their advantages and disadvantages.
