What are air filters?
Clean air filters can improve the efficiency of your HVAC system and the air you breathe. Air filters are barriers that collect dust, allergens, and other materials that would otherwise enter the air you breathe.
When do I need to change my air filter?
Since there may not be obvious signs that your air filter needs replacement, improve your maintenance routine by setting a reminder. Air filters should be changed every 90 days, give or take. Recommendations can vary based on location, pets, age of equipment, and other factors. Changing an air filter is a simple task that most can do on their own. To determine the size of your air filter, you can remove the existing filter and locate the dimensions. You can also refer to the system’s owner’s manual.
Reasons why you should change your air filter regularly:
- Improve air quality: Dirty air filters can trap air and moisture which can contribute to the growth of mold and bacteria. Eventually, these microbes can spread into the HVAC system, and the air you intake. By ensuring your air filter is changed regularly, you can improve air quality and reduce the risk of mold and bacteria.
- Promote a longer lifespan of your HVAC system: A dirty air filter can cause your HVAC system to work harder. In addition, a dirty air filter can prevent air from moving through. By maintaining a clean air filter, you can promote greater efficiency and a longer lifespan for your HVAC system.
- Save on energy costs: Continuing on the previous benefit, a clean air filter can help your machine operate more efficiently. As a result, you keep your utility bill as low as possible.
- Maintain consistent air temperature: Dirty air filters can interfere with temperature signals. This can cause your HVAC system to start or stop when it’s not supposed to, making it hard to maintain a consistent air temperature.
- Prevent dirty air ducts: Dirty air filters can increase the chance of pollutants building up. The cost and level of effort of changing your air filter compared to cleaning polluted ducts is much more manageable.
