Newer systems typically use pleated filters, also rectangular ones with a depth of about one inch. You should replace them approximately every 90 days, if you don't have allergies, but AC professionals generally recommend every 45 days for maximum efficiency. Be sure to replace them with the correct size and type of air filter. In general, most air filter manufacturers and HVAC companies recommend changing the air filter every 90 days or 3 months.
That may change depending on the location of your home (e.g. EJ. 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. Fiberglass air filters are the more affordable of the two, but less efficient at capturing dust and particles in the air. They usually need to be changed every 30 days or less.
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. While these factors affect the frequency of air filter replacement, you should visually inspect the filter every month for excessive particulate buildup.
If there is a visible layer of dirt that covers most of the filter surface and that is thick enough to hide the filter material itself, it is a sign that the filter has been in the HVAC system for too long. If you have questions about replacing your air filter, or if you need any air conditioning or heating services, Energy Air can help. After a period of smoky days with poor outdoor air quality, inspect the air filter to see if it needs to be replaced. As a general rule, it's a good idea to replace the air filter in your HVAC system every month.
It's important to note that there are high-efficiency filters that are designed to filter out small bacterial, mold, and fungal particles, but your standard MERV 8-11 filters will simply block out larger particles of dust, dirt & hair. If you have allergies, you can reduce your symptoms by using a high-quality air filter and adopting a more frequent replacement program. There is no strict guideline, but if the filter shows only a subtle layer of dirt under which the filter material is still visible, the filter is in good working order. Air filters typically have a MERV (Minimum Efficiency Report Value) that determines the type and size of contaminants against which the filter will act.
Cats and dogs typically lose the most when winter turns to spring and summer to fall, which are key times to replace the filter. One of the most common questions Florida homeowners have about their home's air conditioning system is how often they should replace the air filter in their air conditioner. The only type of filters that trap allergens and spores are HEPA, or high-energy particulate air filters. Typical recommendations range from every 30 days for cheaper fiberglass filters (which often don't do a good job of filtering), to 6 months for high-end pleated filters.
If the dirty air filter is completely covered with dust and dirt, it is a good idea to change the filter even if it has not reached the end of its recommended life. When it comes to replacing your AC's air filters, there are several factors that come into play. The environment in which your home is located plays an important role in determining how often you should replace your AC's filters. Additionally, if you have pets or suffer from allergies or respiratory conditions, then you may need to replace your AC's filters more frequently than normal. In general, most experts recommend replacing your AC's filters every 90 days or 3 months.
However, this may vary depending on where you live (e.g., dry and dusty climates), whether or not you have pets in your home, and how old your system is. If you have pets in your house, then it's best to replace your AC's filters every 60 days or 2 months; for households with multiple pets or people with allergies or respiratory conditions, we recommend changing them every 20-45 days. Vacation homes or homes that don't get much use can usually wait until 9-12 months before needing a new AC filter. It's important to note that there are high-efficiency filters available that are designed to capture small bacterial particles like mold and fungi; however, standard MERV 8-11 filters will only block out larger particles like dust and dirt. If you're looking for ways to reduce allergy symptoms in your home then consider investing in a high-quality air filter and adopting a more frequent replacement program. Additionally, it's always a good idea to visually inspect your AC's filters each month for excessive buildup; if there's a visible layer of dirt covering most of its surface then it may be time for a new one.
