When it comes to maintaining a healthy central air system in their home, most homeowners know that they need to change their air filters regularly. But how long does a furnace air filter last? It depends on the type of filter and the quality of the air. Generally, most filters need to be changed every 3 to 6 months. Thicker filters can last longer than thinner ones.
For example, a one-inch oven filter should be changed every one to three months. A three- to four-inch filter can last six to nine months. If you have a five- to six-inch coarse-grained filter, it can last nine to twelve months. Vacation homes or vacant homes that don't have much use can expect to change filters every 9-12 months.
In general, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days or 3 months. This may change depending on the location of your home (e.g. dry and dusty climates), if you have pets, and the age of your system and equipment. If you have pets in your home, 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.The primary function of an oven filter is to trap airborne contaminants, not for air quality reasons, but to keep them out of the heating and cooling system.

Without a filter, the oven would stop working quite quickly because the equipment would be too dirty to work properly.When it comes to replacing your furnace air filter, always follow the manufacturer's recommendations for how often to replace them. As a general rule, most filters need to be changed every 3 to 6 months.

As air moves through a building's HVAC system, air filters trap and pick up large and small particles, such as dust, allergens and microorganisms. When oven filters are forgotten or omitted to change, several problems arise in Cincinnati homes.In conclusion, when it comes to how long a furnace air filter lasts, it depends on the type of filter it is and the good quality of the air.
