Air Filter Best Practices

Changing air filters on a regular basis is a best practice for keeping the HVAC system up and running. However, there are a lot of questions that come up when talking about air filters. 

Like, what are the signs that the air filter needs to be replaced? How often should they be changed? Through this article, homeowners can get answers to these questions and more.

Signs That Say It’s Time To Change the Air Filter

Most air filters have a recommended frequency for how often they should be changed. However, it can be hard to remember when that time hits. In this case, there are a few common signs that tell homeowners when it’s time to change the HVAC filter.

  1. Unusually dusty: Air filters trap dust and other particles to prevent them from moving throughout the home. If the air filter is too dirty, it won’t be able to do its job effectively. Homeowners may begin to see dust collect around vents or more dust floating through the air than usual.
  2. High utility bills: If the air filter is full of dirt, the HVAC system has a harder time pushing air through the filter. This can cause utility bills to spike, so always pay attention to the month over month trends.
  3. Frequent illness: Dirty air filters reduce the quality of the air in the home. It can cause an increase in allergic reactions, sneezing, or coughing. It can also make people feel more tired than usual.

Benefits of Changing Air Filters

There are many benefits of switching out a dirty air filter for a clean air filter. First, it extends the life of the HVAC system. If the air filter is full, dust and dirt will start to accumulate. This can cause the HVAC system to overheat and malfunction. Changing out the air filter also helps to keep energy costs down because the HVAC system won’t have to work as hard to push air through the house when there are clean air filters in place.

In addition to the HVAC system benefits, changing air filters can also have benefits for people’s health and well-being. It helps improve the air quality in the home, which prevents allergy attacks, promotes health, and provides better sleep.

Frequency of Changing Air Filters

As mentioned, air filters should be changed out regularly. However, with so many other day-to-day tasks that homeowners have on their plates, it can be hard to remember. So here’s a good rule of thumb when it comes to changing air filters: the lifespan of a filter often depends on its thickness. 

A 1-inch or 2-inch filter needs to be switched out about every 3 months, a 4-inch filter should be changed every 6 months, and a 5-inch filter should be changed once a year. Also, homeowners can always look on the back of their air filter to see the recommended lifespan. 

Once there’s a timeframe in mind, homeowners can write it down on a calendar or make a note on the phone as a reminder.
