How Often Should Commercial Air Filters Be Changed? An Expert Explains

In controlled indoor environments, such as offices, it is recommended that air filters be replaced at least three to four times a year. This is the standard for HVAC units used in relatively dry and clean environments. Workplaces that are mostly clean and chemical-free can be maintained in good condition with quarterly replacements. Best practice is to put this on your calendar at the beginning of each quarter to make sure it's being done.

In more difficult and unpredictable environments, such as medical or military buildings, more frequent air cleaner replacement may be necessary. In general, most air filter manufacturers and HVAC companies recommend changing the air filter every 90 days or 3 months. This may change depending on the location of your home (e.g. dry and dusty climates), if you have pets, and the age of your system and equipment.

If you have pets in the house, you should consider changing the filter every 60 days or 2 months, and for households with multiple pets or people with allergies or respiratory conditions, we recommend changing the filter every 20 to 45 days. Vacation homes or vacant homes that don't have much use can usually wait to change filters every 9-12 months. The general consensus is that the more you use your home, the more you need to change the air filter. Using an air filter with a MERV rating higher than recommended by the manufacturer of your oven or air conditioner may impair its performance. Meanwhile, air filters in spaces such as medical facilities and military buildings may require more frequent replacement.

Commercial HVAC air filters are designed to keep allergens and dust out of the air, and provide your employees with cleaner air to breathe, while ensuring your air conditioner stays in good operating condition. If you're not quite sure when or how to change the air filters in your HVAC system, don't hesitate to contact a professional. Two simple things you can do to minimize the risk associated with clogged filters are to change them regularly and ensure that you always have an adequate supply of replacement filters on hand. According to a heating service specialist, a dirty air filter is all it takes to reduce airflow inside a building and cause an HVAC system to work too hard, leading to higher energy bills. Air filters are usually made of spun fiberglass (the same as attic insulation) or & pleated paper framed with cardboard for added stability and rigidity. The quality of the filter used by your HVAC system is another factor in how often commercial HVAC filters need to be changed. While there are many factors that contribute to overall air quality, most HVAC repair and maintenance companies will tell you that changing air filters is often one of the most effective ways to improve it.
