Living in southern Nevada, we are often exposed to frequent wind storms that blow dust into our homes. For those with large households, or those with pets, combined with the dust storms, it’s no wonder that many homeowners have to change their air filters often. However, what is too often? While it is to be expected that we need to change air filters more frequently here in Nevada, for those who need to change their air filters every two to four weeks, this could be a sign of another major problem. Air Supply Heating & Air Conditioning will share what can cause filters to get dirty too fast.

Having to Change Air Filter Every 2 Weeks?

Depending on the quality of air filters you may use in your home, it isn’t abnormal to need to change air filters about once a month. Many air filters can last up to three months. However, if you find you need to change your air filter more often than once a month, or when you do change your air filter at the end of the month and find they have collapsed inward due the amount of dirt in the filter, then this may be a sign that there is an additional problem.

Why Do My Air Filters Get Black So Fast?

There are some natural reasons why an air filter may get dirty much more frequently. One is large family households and those with pets. The more people you have walking in and out of the home, the more it allows contaminants to flow through your home. Pets, such as dogs and cats that go in and out of the home, also track in much of the dirt along with dander and hair which often gets sucked up into the air filters. When it comes to this scenario, there is not much you can do to prevent less dirt and contaminants from entering your home. You can however, brush out your pets often to keep down the amount of dander and pet hair. For those who have a large sized family and/or pets, expect to change out your filter about once a month. Perhaps you can go a bit longer if you use a higher quality filter.

Air Conditioner Fan On Continuously

Another common problem for air filters getting too dirty is when the thermostat’s fan setting is left in the “ON” position. When the fan setting is in the “ON” position, the fan is constantly running which means it is also constantly pulling air through the air filters. This causes more dirt to build up inside the air filters. For those who leave the fan set to on to help clean the air for those with asthma or other breathing problems, should consider using an air purifier while the fan is set to on. An air purifier can help clean the air as well and reduce the amount of dirt in the filters. If you don’t need the fan running constantly then make sure you have the thermostat set to “Auto” to help prolong your air filters and even improve your HVAC system’s efficiency.

Poor Insulation or a Leaky Air Duct System

If you have a really dusty home and your air filter gets dirty really fast, another major problem is poor insulation or a leaky air duct system. If you have a leak in the air duct system, it can draw in dust that is then circulated throughout your home. By allowing more dirt into your home the filters will have more dirt and contaminates to deal with. If you have a lot of dirt coming into your home, which causes the need for you to change you air filters every few weeks, have your air ducts inspected and even cleaned to remove all of the dirt inside the air duct.
