Why change your air filters?
Since filters are often not seen, they are easily overlooked. The small to the very large facility can have thousands of dollars invested in HVAC equipment. All HVAC equipment has some type of filter or filters to capture harmful airborne particles. These filters require regular changes.
The old saying "pay now or pay later" applies to air filters. It costs a fraction to change air filters regularly versus the expense of not changing. Not changing air filters results in increased electricity consumption, negative health effects, expensive mechanical damage, and shortening the operating life of the HVAC equipment.
If air filters are not changed routinely, the before mentioned problems will certainly occur and possible many others (mold, mildew, water damage, product damage, productivity loss, fire hazard, etc.)
Routine filter changes are a wise choice.
