How Often Should You Change Your Air Filter?

The ideal is to change your air filter every three months, however, there are certain factors to consider when determining when to replace an old filter. On average, air filters should be changed every 90 days. An HVAC filter will typically last one to three months, so it's important to keep track of the date you installed it. If you wait too long to change the filter, the indoor air quality will suffer.

Estimating how often an air filter should be changed can be complicated due to the many variables involved. Allowing dandruff, dust, and other contaminants to build up in the air filter and reach your home can be hazardous. The type of air filter you buy may also affect how often you need to replace it. So how do you know when your air filter has trapped too much dirt and needs to be changed? If you're unsure, it's best to contact a professional for expert advice and indoor air quality services for your Michigan home.

When the air filter is clean, you don't have to worry about inhaling particles or other contaminants. Unfortunately, many homeowners are unaware of how often air filters need to be replaced, leaving their system vulnerable to damage. Air filters trap pet hair, dust, and other irritating particles so that the air conditioning system returns fresh, clean air to your home. The difficult part of changing the air filter is determining what type of replacement it should receive.

Connecting the filter change to the energy bill makes sense because clean filters improve the efficiency of the air conditioning system and reduce electricity costs. The more pleats an air filter has, the better its chances of removing contaminants from indoor air. Changing the filter more frequently ensures that the filter has enough surface area to capture contaminants that can cause symptoms among loved ones. To get the best performance and optimal efficiency from your air conditioning system, replace filters every 30 to 45 days. Studies have shown that the air in your home can be two to five times more polluted than outdoor air.

It's not a good idea to use the air conditioning system without an air filter, as it won't be able to remove particles and pollutants from the indoor space. Using a washable air filter is also beneficial because you can change it as needed and save money on replacements.
