Different filter manufacturers offer different filter replacement guidelines, but is following them as simple as checking a box?

How Often Should You Replace Your Air Filters?

In general, it is recommended that you replace your air filter every three months. However, there are other factors that can affect how often should you replace your air filters.

If you have pets, you may need to replace your filters more frequently. Pets, especially cats and dogs, shed regularly. This could accumulate in your air filters which could cause them to be dirty faster.

Your air filters would also be subject to quicker replacement if you live in a dusty area. If your home is situated near a busy street or if you are in a city center, dust would also accumulate faster in your air filters.

You will also change your air filters quicker if you have allergies or other respiratory problems. You wouldn’t risk your health just because you want to save money right?

The Benefits of Replacing Your Air Filter

Regularly replacing your air filter has many benefits. One benefit is improved air quality in your home.

Dust, pollen, and other airborne contaminants can build up in your filter over time, reducing the quality of the air in your home. Replacing your filter can help to reduce these contaminants and improve the air quality in your home.

Another benefit of replacing your air filter is increased energy efficiency. A dirty air filter can restrict air flow, causing your furnace or air conditioner to work harder to maintain the desired temperature in your home. This can lead to higher energy bills.

Replacing your air filter can help to keep your heating and cooling systems running efficiently, saving you money on your energy bills.

The Different Types of Air Filters

How often should you replace your air filters also depends on the type of air filter that you are using.

The pleated air filter is the most common type of air filter. They are made of pleated paper or synthetic media. These filters are designed to trap smaller particles, such as dust, pollen, mold spores and pet dander. Pleated air filters typically need to be replaced every three to six months.

Another type of air filter is the HEPA filter, which is made of tightly woven fibers that capture very small particles. These filters are typically used in homes with allergies or asthma, and they need to be replaced every six to 12 months.
