In general, most air filter manufacturers and HVAC companies recommend changing the air filter every 90 days or 3 months. This can vary depending on the location of your home, if you have pets, and the age of your system and equipment. Fiberglass air filters are the more affordable option, but they are less efficient at capturing dust and particles from the air. They usually need to be changed every 30 days or as recommended by the manufacturer.
A pleated air filter should be replaced approximately once every three to six months. However, the frequency of air filter replacement depends on several important factors, such as your home, occupants, and location.Pleated filters are less common than fiberglass varieties, but they are much more efficient and durable. These are some of the best filters available and can last up to six months before needing a replacement (depending on the size of the oven and the quality of the filter). However, it's best to change pleated filters every 90 days to maintain impeccable indoor air quality and unit performance. Ideally, you should change your air filter every three months; however, there are certain factors to consider when determining when to replace an old filter.
Homes with multiple occupants will need to replace their air filter more often than those with a single occupant. If your 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. Replacing the air filter will restore airflow, improve heating and cooling efficiency, and increase air quality throughout the house. Air filters are designed to allow air to flow freely through them while trapping dust, dirt, bacteria, and other contaminants. After a period of smoky days or poor outdoor air quality, inspect your air filter to see if it needs to be changed.
Changing your air filter every 30 days is a great way to reduce allergy symptoms and improve your overall health. Over time, the filter can become clogged and restrict the flow of air that passes through it and into your home. However, people in colder climates whose ovens are not interrupted for months may prefer to change their filter every 30 or 60 days because more air passes through it and clogs up more quickly. I checked my filter and found that it was covered with dust, so I replaced it with a new one and now my indoor air is much cooler. Clogged filters not only have a negative impact on a home's air quality but also force the oven to work harder to get air into the system which can shorten its lifespan. Pleated air filters are more expensive at first but they're also more efficient at trapping particles and can last up to 90 days depending on use. In most cases, air filters with a MERV rating equal to or lower than 16 are designed for residential, commercial, and institutional air conditioning systems. Consider replacing a fiberglass air filter about once every 20 days and replacing a pleated air filter about once every 60 days if you have one or more pets.
During these months pollutants in your home may increase but the air filter doesn't catch them.
