4 Signs You Might Need To Change Your In Home Air Filters

A clogged home air filter can make a big difference in the quality of your indoor air. In most urban settings, the air is not only full of germs but other pollutants as well. Air pollution is common, and even people who don’t live near an industrial area or a major city often complain of breathing in polluted air. If you have a clogged home air filter, you’re not alone; many people suffer from this problem.


Air filters do not only keep the air moving inside your house; they also clean it out. They take out any harmful substances and contaminants that might be stuck inside your system. This is the reason why you should regularly check if your air filters are clean, so they work at optimum levels.

How Do Air Filters Work? 


An air filter is one of the most important tools that you should invest in if you want to maintain your health. Air pollution is one of the major causes of asthma, allergies, and other respiratory issues. Even if you’re not prone to these problems, you need to keep the air you breathe clean and healthy. 


High quality air filters from filterking.com work by catching particles and dust and keeping them out of the circulating air in your home. They remove the impurities that might otherwise cause you to experience health problems because they’re bad for the system itself. 


Air filters also help keep dirt, dust, tiny particles, and other foreign objects from entering your cooling system and prevent it from running properly. Some filters come with a single part, while others come in multiple parts that have to be assembled to keep the machine running smoothly.

Signs You Need To Change Air Filters 


The simplest type of air filter is the disposable type. These are just a bag filled with foam, paper, or carbon. A simple filter consists of a bag filled with the material, an air trap, and an air outlet. An outlet is often attached to a fan, which is used to blow the air through the filter bag. The main disadvantage of disposable filters is that they can be hard to clean and remove excess air. 


This is twhy you should always change the air filters of your home. If you’re unsure if your air filters need changing, here are four signs you should look for:  



  • You Frequently Get Allergies 



First off, if you have small particles in your air, you may have asthma or allergies. The small particles may not bother you if you don’t breathe them in. However, if they are inhaled, they can cause irritation and inflammation of the airways. For instance, if you have a person with asthma, their lungs will feel like they’re on fire because of tiny dust particles. This irritation can lead to asthma. 


Allergy symptoms can range from something as simple as dry skin or hives to more serious health conditions like asthma. If you have never experienced an allergy before, it could be a sign that your air filters are no longer filtering the dust properly inside your home. 



  • Bad Smells Always Linger In Some Parts Of The House 



If you’re noticing undesirable odors that weren’t present before, there could be a build-up of bacteria in the air filter of your home. Another concern of those who have allergies and asthma is that the bacteria build-up in their home air filter may lead to respiratory problems. 


When air goes through the filter, the bacteria also gets pushed through the air ducts and right inside your home. As soon as you smell something that isn’t right, you need to check if your HVAC system filters. If the issue persists, there may be other places in your home filled with bacteria or even mold, which causes the bad smell.  



  • You Observe Your Electric Bill Going Up 



If you’re monitoring your electric bill and seeing that your consumption went up, your air filters might be the culprit. When the air filters are clogged up, your HVAC system tends to overwork so it can filter as much air as possible. This is because when the air filter is clogged, your HVAC system uses more power to force the air through the vents. 



  • Your HVAC System Is Not Working Properly 



Several things make your ducts dirty. These include dirt, oil, dust, hair, and debris. These items can also clog your air filters and can go inside your HVAC equipment. When the air ducts and air filters are left unchecked, these will affect your HVAC system performance. If you feel your air conditioning is not getting your room cool, chances are clogged air filters are the culprit.  




Keeping the air quality in your home clean is critical to keep everyone healthy and free from illnesses like asthma and other respiratory diseases. Changing your air filter regularly will also help keep your HVAC system running at optimum and your electric bill in check. Keep a lookout for the signs above to help you determine when you should change your air filters.
