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.
The only way to ensure how often you need to change your air filter is to perform a visual inspection of the filter every month. After a few months, you'll get an idea of how quickly it gets dirty. You will need to re-evaluate if you have a new pet or if the outdoor air quality has been poor. 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. When you buy a new air filter, you'll find the manufacturer's recommendations for the replacement program. In smaller homes, the HVAC system has to move less air, which can mean less frequent air filter replacements. Households with a pet should generally replace filters after two months; those with more than one pet may need to replace the filter once a month. Outdoor air quality can have a big impact on how often the air filter becomes dirty and needs to be replaced. However, it will put unwanted pressure on your HVAC system, resulting in poor air quality and air circulation.
If you have any questions, call a professional or the manufacturer of the air cleaner to determine its service life. Consider replacing air filters after a major home renovation to keep the air clean and reduce the chances of costly maintenance repairs later on. Furnaces and air conditioners in smaller homes need to pump less air for the same amount of temperature change, which can mean less frequent filter changes. An air filter manufacturer will generally explain how often you should replace the air filter in their installation instructions. A good rule of thumb is that if debris needs to be vacuumed more frequently from the floor, it can be safely said that this debris also goes to the air filters. If you live alone, without pets, and with good surrounding outdoor air quality, the manufacturer's filter change recommendations will probably work well for you.
