Air Filtration, We Are All Guilty of Forgetting About Our Air Filters

Updated: Mar 12

It's safe to say that we go through the day without thinking about the air we breathe. Unfortunately, that air is likely filled with impurities that can cause damage if not properly filtered.


Fortunately, HVAC systems aren't just designed to keep you comfortable; they're also designed to keep the air clean. Every system has an air filter that cleans the air before it is pushed into your home. It's an excellent system that works well if everything is installed correctly.


The important thing is to make sure you do everything right. You can get cleaner air by avoiding these common air filter mistakes.


Clogged, Dirty Furnace Air Filter


Neglected HVAC Inspections

Air filters get clogged with dirt and dust over time, so it's essential to know when to replace them. Some heating and cooling systems have sensors that alert you when the air filter needs to be changed. Usually, the air filter should be replaced at a minimum every three months.

Though, during seasons when the HVAC system is in constant use or unusually dusty locations, it may be necessary to replace the air filter monthly.

It is crucial to carry out frequent HVAC inspections. In addition to identifying major maintenance issues, regular inspections also minimize the risks to respiratory health.


Forget to Change the Filters

Don't forget to change the air filter too. Waiting too long can cause other unwanted problems. Regular replacement will improve the air quality in your home. This way, you can maximize efficiency and save more money in the long run.


Incorrect Size

There are several types of HVAC systems on the market. Each system requires a different size air filter. So pay attention or seek professional help from experts to ensure you choose the right size. If the filter is too small, there will be a gap between the frame and the spot, reducing efficiency. A filter that is too wide will not filter the air properly.


Tip: Measure the size of the space where you will install the air filter and write it on the ductwork.


Incorrect Installation of Air Filters

A common mistake homeowners make is installing the air filter upside down or backward. Fortunately, once you learn the correct installation method, it's easy to remember for future reference.


In some cases, this is not the current homeowner's fault but may be due to receiving incorrect information from the previous owner or a third party. There should be an arrow next to the filter.


This arrow should point toward the indoor unit and away from the air-carrying ducts. If the arrow points in the wrong direction, the filter isn't working correctly and needs to be turned.


Overall, an air filter should protect the user from naturally occurring airborne pathogens in the indoor environment, such as dust.

Do not try DIY and ask a trained professional to install the filters correctly to avoid any costly mistakes.


Not Paying Attention to MERV Rating

One important thing to keep in mind when choosing an air filter is the MERV rating.

The higher the number, the more particles the filter will capture. So, essentially, you want an air filter with a high MERV rating to help filter out as many particles as possible. A MERV rating can help you find the filter you are looking for.
