Read this article to find out more.

What Is an Air Filter?

An air filter is a device that removes solid particulates. It prevents these dangerous particles from circulating the air that people breathe in their homes. It should trap dust and some can even trap things such as smog and odors.

Most air filters are made with either fiberglass or pleated filter media. The materials and amount of media used will determine the filtering capability of the filter. Let’s dive into some of the different types of filters and what they do.

Types and Functions of Air Filters

When buying an air filter, you must consider several things. You must know what size air filter to buy. You must also know what level of filtration is right for you and your home. 

Once you know the size, you should determine what type of air filter you need. A fiberglass filter is a common, affordable air filter found on the market. It consists of layered fiberglass fibers.

These filters are great for saving money, but they do very little in the way of filtering particles or maintaining your indoor air quality.

There are also pleated air filters. These pleated filters are the best mix of affordability with varying levels of filtration that can remove everything from pollen to virus carriers, depending on the MERV rating you opt for.

Did you know there are washable air filters too? This type of air filter is newer to the market but can help you save money in the long run.

The MERV Scale Rating

You might be asking, “How do I know which air filter is more efficient?” You can use the Minimum Efficiency Reporting Values (MERV) scale to find out.

The MERV scale runs from 1 through 20. Filters with higher numbers are better at removing particles from your air. 

To find out what number you should buy, you need to determine the job you want the filter to do. Are you looking for simple dust reduction? A Dust Filter is likely right for you. Have someone with allergies? An Allergy Filter is right up your alley. If someone suffers from respiratory illnesses like asthma, COPD, or emphysema, a Health Filter is right for you.

How Are Air Filters Made?

Air filters are made using different materials. The process starts by gathering the raw materials. 

Depending on the type of filter, the raw materials can include CRCA sheets and PU foams. 

Materials also include enclosures and filter paper. The filter paper can come in different grades. The grades depend on the filter’s applications.

The machines required to make air filters also vary. A rotary pleating machine and a marking machine help to piece the air filters together, while the pleat cutting machine and the tube rolling machine also do the job.

Why Should You Replace Your Air Filter 

There are several reasons why you must replace your air filter. It’s a good idea to have a clean air filter at all times. 

A dirty air filter can increase your energy bill. If you have a dirty air filter, it’ll cause the HVAC system to work harder. You can save money by making sure you change the filter every 2-3 months. 

A clean air filter will improve airflow. It’ll also improve the HVAC system’s efficiency. In turn, this helps to allow the air quality in your home to remain at your desired level.  

What homeowner doesn’t want to have their HVAC system work well for years? Dirty air filters can lead to your system failing.

Don’t end up having to pay for repairs that can cost an arm and a leg. You might end up having to pay for a new HVAC system.
