All the air that circulates through your HVAC system, whether for heating or cooling your home, will eventually pass through the air filter. That's why it's very important to keep your air filters clean and change them regularly. In general, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days or 3 months. That 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 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 20-45 days. Usually, vacation homes or vacant homes that don't have much use can expect 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.
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. The ideal is to change your air filter every three months, however, there are certain factors to consider when determining when to change an old filter.
Experts recommend changing it once every 30 days if your air filter is made of fiberglass filters, which are of relatively poor quality. On the other hand, expensive pleated filters can work well with a replacement once every three months or six months. Naturally, air filters need to be changed in the event of damage. However, to maintain the maximum possible performance of your car, it is recommended that you replace your air filters at least every 12,000 to 15,000 miles (19,000 to 24,000 km).
This interval should be reduced if you often drive in dusty conditions. It's best to review the maintenance schedule provided by your car manufacturer to get the proper replacement program. Maintenance schedules for different vehicle brands differ in how often the air filter needs to be changed. The purpose of the engine air filter is to prevent dust, dirt and other environmental contaminants from entering the engine.
The owner's manual should give you a more accurate estimate of exactly when your vehicle requires a new air filter. The cabin air filter should also be changed periodically, but at a different time than the engine air cleaner. After discussing in detail how often your air filter needs to be changed, it's important to know which type of air filter is ideal for your needs. 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.
While these factors affect the frequency of air filter replacement, you should visually inspect the filter every month for excessive particulate buildup. According to the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), this filtration helps provide healthier indoor air quality. As mentioned above, the presence of pets, young children, and people with allergies will require you to change the air filter more often. 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.
On the other hand, smaller rooms will not require much air pumping, which implies a lower frequency of filter replacement. As you can probably tell from the name, air filters help keep your car's air clean by trapping dirt, debris, and other harmful contaminants before they enter your cabin. You will no longer be able to filter the air properly, allowing dust and contaminants to enter the HVAC system. Compared to other DIY home improvement projects, changing air filters is a quick and painless process that can be done in less than an hour.
However, it will put unwanted pressure on your HVAC system, resulting in poor air quality and air circulation.
