In general, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days or 3 months. This may vary depending on the location of your home, if you have pets, and the age of your system and equipment. A good rule of thumb is to keep track of how long the air filter has been in place. The average length of service for an air filter is usually between 10,000 to 15,000 miles, which for most people is approximately once a year.
However, this is just a recommendation and doesn't take into account individual driving situations. The frequency of changing your car's air filter depends on how often you drive. Generally, it should be changed every 30,000 miles. Fiberglass air filters are more affordable but less efficient at capturing dust and particles in the air.
They usually need to be changed every 30 days or less. It's a good idea to check all your filters at the same time, especially if you have children in the house as they are more sensitive to indoor air pollutants such as mold, dust mite debris, dander and pollen. It's important to regularly check your engine's air filter to make sure it's clean. A clean air filter ensures that the engine receives the correct amount of air needed to operate at its maximum level.
Maintenance schedules for different vehicle brands differ in how often the air filter needs to be changed. A dirty filter doesn't necessarily mean it will burn more gas. If you have allergies, you can reduce your symptoms by using a high-quality air filter and replacing it more frequently. Replacing your engine air filter is an often overlooked maintenance item, but a dirty air filter can have a negative effect on your car's performance.
When you buy a new air filter, you'll find the manufacturer's recommendations for the replacement program.Others suggest visually checking the air filter and changing it when it looks dirty. Most engine air filters are easy to access and you can check the location in your owner's manual if you need help. The frequency of changing your air filter also depends on how often you use your home - a vacation home where you only live part-time will need far fewer filter changes than a large family home with numerous occupants.
