In general, most air filters should be changed every 90 days or 3 months. This may vary depending on the location of your home, if you have pets, and the age of your system and equipment. The ideal is to replace your air filter every three months, however, there are certain factors to consider when determining when to switch out an old filter. An HVAC filter will only last one to three months on average.
This means you should keep track of the date you installed them. If you wait too long to change the filter, indoor air quality will be affected. When the air filter is clean, you don't need to inhale particles or other different contaminants. Replacing filters regularly can keep homeowners and their families healthy through efficient air circulation.
If someone in your household has a condition that affects their lungs and breathing, change the filters more often. More cycles mean more passes through the filter and opportunities to trap contaminants, so filters tend to fill up faster during periods of heavy use. If you're allergic, be sure to take note of how often you change your filters and always make sure you're using the correct type of filter. To get the best performance and optimal efficiency from your air conditioning system, replace filters every 30 to 45 days.
Some manufacturers recommend replacing air filters every 30 to 60 or 90 days, depending on the type of air filter. Investing in a relatively inexpensive air filter and replacing the filter at the right time can save you a lot of money on repairs. Over time, the air filter accumulates dirt, dust, fur, and other contaminants that can be found in the house. If someone in the family has severe allergies, it is recommended to change air filters very often, in some cases, every two weeks. There are many different factors that influence how often you need to change the filter, but you can't go wrong if you schedule systematic and routine filter changes.
As winter turns to summer, you'll notice that you'll have to use the filter every day (or almost), due to the increased amount of particles and allergens in the air. In situations where you can't find the MERV rating on the air filter packaging, you can look for a filter with many folds per foot. Studies have shown that the air in your home can be between two and five times more polluted than outdoor air. While these factors affect the frequency of air filter replacement, you should visually inspect the filter every month to check for excess particulate buildup. To ensure optimal indoor air quality and prevent costly repairs down the line, it's important to stay on top of your home's air filter maintenance schedule. Changing your air filters regularly is an easy way to keep your HVAC system running efficiently and maintain a healthy home environment.
