You come back from a nice relaxing vacation, and open up your fridge for a snack… and you’re greeted with the smell of something way past its expiration date. That smell can linger, and quickly get rid of your post-vacation glow. 

Expired food, mold, and other mysterious smells in your fridge can be both unappetizing and unhealthy. Luckily, it’s easy to prevent odors and even bacterial growth.

All it takes is the proper maintenance of your fridge air filter! By replacing your air filter periodically, you can ensure the freshest, healthiest food for you and your family. Even if you forget about the milk while you’re out of town.

In this article, we’ll discuss everything you need to know to maintain your filter. Read on to learn fridge air filter tips that can keep your family’s food safe!

What Do Fridge Air Filters Do?

Fridge filters are small, flat, filters made up of several layers of fabric. Between the layers, they often have activated charcoal, an effective deodorizer. 

Fridge filters fit in the air passageway of your fridge compartment and clean all the air that enters the fridge. They also clean the air that circulates throughout the fridge. 


A fridge is basically a closed box for your food. If something spoils, or if bacteria enter the fridge, it doesn’t take long to spread in this confined space. If bacteria or foul odors spread in your fridge, they could settle on your food! 

Many people use baking soda to deodorize their fridges. However, a box of baking soda is only effective in a small area of the fridge. With an air filter, the entire air pathway is filtered.

Air filters neutralize odors and ensure that only fresh, sanitized air is passed around your fridge and over your food. This ensures your fruits and vegetables can stay crisp and clean for longer.

Health Benefits

The NSF performed a study that found that the fridge is one of the dirtiest appliances in the kitchen! In the vegetable compartment alone, they found a variety of germs like Salmonella, Listeria, mold, and yeast!

You can’t completely prevent germs in the kitchen. However, with proper maintenance of your fridge air filter, you can take action to prevent the formation of most bacterial colonies within the fridge.

By preventing bacteria and other microbes from entering your fridge, you prevent your family from consuming them. Healthy food means healthy family members! 

Additionally, if someone in your family has allergies or asthma, polluted air can impact their health. Using an air filter in your fridge, you can keep these contaminants out of their food.

Pet owners should also be sure to maintain their air filter, as pet dander and hair can enter the fridge via the air passage. 

Energy Efficiency

If you neglect your fridge air filter, it can get clogged up with particulates. Not only is this unhealthy, but it can also cause your electric bills to go up.

When the air filter is impacted, the machine has to work harder to pull in and circulate air. The harder the machine has to work, the more energy it consumes and the more heat it can give off. Keep your energy bills down by keeping your fridge functioning smoothly. 

Replacing Your Air Filter

Proper care and maintenance improve the effectiveness of both your air filter and your fridge. Replacing your fridge air filter is very easy. The process can be completed in just a minute or two! 

Finding Your Air Filter
