How Often Should You Change the Filter for Your Air Conditioner?

When it comes to air conditioning systems, it's important to know how often you should change the filter. Newer air conditioning systems typically use pleated or rectangular filters with a depth of about one inch. Generally, it is recommended to replace them every 90 days if you don't have allergies, but air conditioning professionals usually suggest changing them every 45 days for maximum efficiency. The only way to be sure how often your air filter should be changed 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'll need to re-evaluate if you have a new pet or if the outdoor air quality has been poor. Ideally, you should change your air filter every three months; however, there are certain factors to consider when determining when to change an old filter. Although many professionals recommend a new filter every 90 days as a general guideline, there are a number of factors that will affect the filtering schedule. After a period of smoke-filled days and poor outdoor air quality, inspect the air filter to see if it needs to be changed. If your house is in a city or on a busy street, you should change the filter more often to prevent pollution from entering the air in your home.

If the house is full, you'll want to change the filter every three to six weeks to keep the air quality clean. Air filters help maintain good air quality in your home and can reduce allergies and respiratory problems. Accordion filters are usually of higher quality, because their shape and design allow more air to pass through the filter. If you live alone, don't have pets, and the outdoor air around you is of good quality, the manufacturer's recommendations on changing the filter are likely to work well for you. With the new filter in hand, simply change the air filters by removing the old ones and replacing the new ones in the same position as before.

Your home air filters should be changed regularly to keep the system running smoothly and to maintain optimal air quality. When determining how often to change an old filter, there are several factors that should be taken into account. If you live in a family home that depends heavily on the air conditioning system for heating and cooling most weeks of the year, then you'll want to change the filter every 90 days at most. Air filters trap pet hair, dust, and other irritating particles so that the air conditioning system returns fresh, clean air to your home. In smaller homes, the air conditioning system has to move less air, which may mean replacing air filters less frequently.

On top of that, air conditioning filters offer even more advantages, but you won't be able to enjoy any of them if you work with a dirty filter. How often do you use the system? The more often you use an air conditioning system, the faster the air filter will fill with dust and dirt.
