Your HVAC system’s overall efficiency is directly impacted by the type of air filter you select because it is responsible for capturing airborne particles that can harm both your health and expensive system components.

If you’re one of the many homeowners who uses disposable HVAC filters, you might be unsure whether a washable filter is appropriate for your home. Let’s find out!  

Key Takeaways: 

• Disposable air filters should be changed every 30-60 days. 
• Washable filters are more expensive but last much longer than disposable options.  
• Washable air filters have a MERV rating of 1-4, which means they can capture particles that are larger than 10 microns including pollen, dust mites, and lint.  

Different Types of Air Filters  

To decide if a washable air filter is best for your home, we first have to discuss what types of air filters are available.  

Disposable Fiberglass Air Filters  

The fiberglass mesh used in these traditional flat-panel filters is stretched over a cardboard support structure. As air moves through the fiberglass mesh, debris is collected.

Disposable fiberglass filters are the most common and affordable type of air filter, but they must be replaced at least every 30-60 days to maintain HVAC efficiency. 

Washable Mechanical HVAC Air Filters  

Particle buildup can be removed from washable or reusable filters by rinsing or vacuuming them clean. For maximum particle capture, they are typically composed of woven polypropylene media and are electrostatically charged.

Because they can be reused, washable air filters are more environmentally friendly than other filters, but they are more expensive.  

Disposable Pleated Air Filters  

Like their fiberglass counterparts, disposable pleated HVAC filters are single-use, but they are constructed differently. Since there are multiple layers, there is greater surface area to trap particles in pleated filters composed of pleated cotton or plastic fibers.

Remember, disposal pleated air filters cannot be washed or reused.  

HEPA Air Filters  

HEPA stands for “High-Efficiency Particulate Air.” These filters are highly effective at removing particles that are 0.3 microns or larger from the air. (That’s tiny!) 

In medical settings like clinics, hospitals, and labs where clean air is crucial, HEPA filters are most commonly utilized. It’s crucial to remember that high-density HEPA filters can be very expensive and that not all HVAC systems can handle them.

You can buy HEPA filters in washable or disposable options.  

UV HVAC Filters  

UV HVAC air filters are not made of fiberglass, cotton, or plastic. Instead, UV filters utilize ultraviolet light to get eliminate airborne debris, including germs, viruses, and microorganisms like mold.

These kinds of filters are often used to supplement other types of air filtration systems.  

Why Choose a Washable Air Filter?  

Now that we have a basic understanding of the different types of HVAC air filters, we can now discuss the benefits of washable air filters.  

Washable air filters are becoming increasingly popular as people look for ways to save money and reduce their impact on the environment. There are several benefits to using these kinds of air filters including: 

#1. Energy Efficiency  

Washable air filters have a MERV rating of 1-4, which means that the filter can capture particles that are larger than 10 microns. Pollen, dust mites, and lint are all 10 or more microns in size, so a washable filter will prevent these particles from circulating through your HVAC system.  

When your system is free of debris, it has greater  

efficiency and better performance.   

#2. Environmental Impact  

Since you are washing your air filter once every month or two to be reused again and again, you are lessening your impact on the environment. Some air filters can take a long time to break down in a landfill depending on what they are made out of.  

#4. Savings  

A well-maintained washable HVAC filter can last 5-10 years before needing to be replaced. Think about how many disposable filters you might use in this timeframe! That is A LOT of savings!   

Though washable air filters are more expensive to purchase than disposable options, their benefits far outweigh their cons.
