Why Are Electrostatic Filters Better Than Regular Filters?

June 23, 2022

The air filter is a major component of your HVAC system. It keeps airborne particles like dust and pollen from circulating through your home. Finding out what type of air filter is right for you will help improve your sense of comfort at home. For example, environmentally minded homeowners could prefer an electrostatic air filter. Typical filters can’t be recycled and are normally replaced every couple of months. Instead, an electrostatic filter can be washed off and reused.

What Is an Electrostatic Air Filter?

An electrostatic air filter is distinct from media filters, which are nonreusable. Media filters are pleated and use an extremely thick network of small fibers to capture airborne particles. While this design is successful, eventually the filter is clogged with contaminants. Instead, an electrostatic filter uses the attractive force of static electricity. Animal dander, mold spores and other contaminants are sucked into the filter and trapped. But because of the lack of fibers, electrostatic filters can be washed.

Washable air filters are recommended for people who like to minimize waste. When kept in good shape, an electrostatic filter can last you a very long time. Meanwhile, your traditional furnace air filter should be replaced every few months. When furnaces can last for up to 20 years, that’s a lot of filters to throw out.

Do Electrostatic Air Filters Have a MERV Rating?

The MERV rating system is a great way to tell how efficient an air filter is at eliminating contaminants. The higher the filter’s MERV rating, the more effectively it works. Ratings are as high as 20, but these are reserved for special filters for medical and industrial use. Instead, a good standard for residential air filters is between a 3 and a 6 MERV rating. These are usually more than adequate for your home’s needs, but there are exceptions.

People with breathing complications or acute allergies can benefit from a more powerful residential filter like HEPA filters. A HEPA filter can remove up to 97% of airborne particles, keeping indoor air quality very high. These filters are often found in dedicated air filtration systems. Additional filtration could also be worthwhile for the elderly and people with respiratory ailments.

Are Electrostatic Air Filters Better Than Disposable? A Comparison.

As you can see, there are advantages to using electrostatic air filters in your home. It just depends on analyzing your indoor air quality needs and making the ideal choice. Let’s compare the main benefits of an electrostatic filter:

Reusable and easy to clean: Unlike pleated media filters, washable air filters are recyclable and reusable. All you need to do is properly rinse them off. Leave enough time for them to dry completely and they can be inserted back in your HVAC system.

Long-lasting with consistent upkeep: To work at their peak effectiveness, electrostatic filters should be cleaned every month. This is a quick process that offers long-term benefits. Washable air filters are highly durable and can survive the lifetime of your HVAC system when properly cared for.

Offers excellent layer of protection: While HEPA filters or dedicated air filtration systems might offer strong results, that doesn’t mean other filters are substandard. For your average home, an electrostatic filter is a superb option for getting rid of airborne particles.
