A general rule for pleated air filters (such as those manufactured by FilterBuy) is to change them every 90 days. As the filter traps more dirt, dust and allergens from the air, its efficiency decreases. But how often do you actually need to change the air filter in your HVAC system? Learn the four factors that influence how often you should replace your air conditioner air filter. On the other hand, expensive pleated filters can work well if replaced once every three to six months.
Different types of oven or air conditioner filters have different specifications for when they should be replaced. Fibreglass filters have a lower price; however, they will need to be replaced more frequently (usually every 30 days). Pleated air filters are more expensive than fiberglass filters with higher quality materials. These filters can last between 3 and 6 months, depending on other factors. As a general rule, it's a good idea to replace your HVAC system's air filter every month.
However, several factors can affect this time. For example, in Florida, during the warmer months of the year, you probably use your cooling system a lot. While during mild winters, you may not use your HVAC system much. During the times you use your system frequently, you can even benefit from replacing your filters every few weeks instead of every month. In addition, if the air filter is not replaced accordingly, it can increase a homeowner's energy bill, as clogged filters make the system work harder by circulating air.
Although it's a good rule of thumb, you'll need to check your air filter more often to see if it needs to be replaced. Numerous contaminants and debris, including excess dust, can cause air filters to become clogged and reduce air circulation throughout the home. After a renovation, such as a drywall project, pieces of drywall, dirt and dust may build up in the air ducts, restricting air flow through the air filters. However, many homeowners are unaware of how often air filters need to be replaced, making their system vulnerable to damage. There is no strict guide, but if the filter only shows a subtle layer of dirt under which the filter material is still visible, the filter works properly. At this time, it is recommended to replace air filters with quality filters that can filter out common allergens, including pollen.
Consider replacing air filters after a thorough home renovation to keep the air clean and reduce the chances of costly maintenance repairs later on. If you want a dog or cat that is hypoallergenic or doesn't lose hair or hair, you may not need to replace your air filter as much. Therefore, there is no clear answer as to how long the air filter can operate efficiently before needing a replacement. After analyzing in detail how often the air filter should be changed, it is important to know the ideal type of air filter for your needs. A single person without pets will have to change their air filters much less frequently than a family with children and several pets. In Florida, you may need to change air filters more frequently due to the presence of moisture, mold, dust, and other allergens. Clogged filters not only adversely affect the air quality of a home, but they also force the oven to work harder to attract air to the system and thus shorten the life of the oven.
If the dirty air filter is completely covered with dust and dirt, it's a good idea to replace it even if it hasn't reached the end of its recommended lifespan.
