In general, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days or 3 months. That may change depending on the location of your home (e.g. 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 20-45 days. Usually, vacation homes or vacant homes that don't have much use can expect 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. The general recommendation for how often air filters should be changed can range from every 30 days to every year.

Two of the determining factors for the life of a filter are the type and quality of the filter being used. A general rule of thumb for pleated air filters (such as those manufactured by FilterBuy) is to replace the filter every 90 days. As the filter traps more dirt, dust and allergens from the air, the efficiency of the filter decreases. Find out below if you should replace the filter more often.

Air filters need to be changed every 90 days on average. An HVAC filter will only last one to three months on average. Which means you need to keep track of the date you installed them. If you wait too long to change the filter, indoor air quality will suffer.

You can hear it: Your HVAC technician is giving you lessons on how to make sure you change your air filter. However, many homeowners are unaware of how often air filters need to be replaced, making their system vulnerable to damage. Estimating how often an air filter should be changed can be difficult because of the many different variables at play. Filters with higher MERV ratings trap small particles more effectively than filters with lower MERV ratings.

However, if replacing the air filter simply isn't possible for an extended period, going beyond 90 days won't cause irreparable damage to your air conditioning system. The Minimum Efficiency Report Value (MERV) scale provides professionals with a consistent standard to use when evaluating the quality of their air filters. However, the smaller the appliance used for cooling, the small space usually comes with smaller filters, so you may need to change the filter as often as a filter in a larger home. The lifespan of an air filter is also affected by the occupants of the home and the characteristics of the home itself.

If you don't like the idea of throwing out the air filter every two weeks, invest in a washable air filter. For your comfort and well-being, and possibly to help you save money in the long run, regular filter inspections and replacement should be part of routine air conditioner maintenance. However, if you need to run your system without an air cleaner, you shouldn't run it longer than six hours. Changing the filter more frequently ensures that the filter has the available surface area needed to filter contaminants that trigger symptoms among your loved ones.

By removing the air filter from the air handler, if you hold it close to a light source, you can see if the filter is dirty or clogged; if you can't see the light through the filter, it's definitely time to change it. It's important to note that there are high-efficiency filters that are designed to filter out small particles of bacteria, mold and mildew, but your standard MERV 8-11 filters will simply block out larger particles of dust, dirt %26 hair. That's why most companies refer to a particular scale when measuring the efficiency of their filters. But how often do you need to change the air filter? How often do you need to change the oven filter? Well, it depends.
