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. Figuring out what type of air filter is right for you will help improve your sense of comfort at home. For example, environmentally inclined homeowners may opt for an electrostatic air filter. Standard filters can’t be recycled and are generally replaced every couple of months. Instead, an electrostatic filter can be rinsed off and reused.

What Is an Electrostatic Air Filter?

An electrostatic air filter is different 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 effective, ultimately the filter is clogged with contaminants. Instead, an electrostatic filter uses the magnetic force of static electricity. Animal dander, mold spores and other contaminants are drawn into the filter and trapped. But because of the absence of fibers, electrostatic filters can be washed.

Washable air filters are recommended for people who want to cut down on waste. When kept in good shape, an electrostatic filter can last you a very long time. Meanwhile, your typical furnace air filter should be exchanged every few months. When furnaces can last for up to 20 years, that’s a lot of filters to throw away.

Do Electrostatic Air Filters Have a MERV Rating?

The MERV rating system is an easy way to recognize how efficient an air filter is at trapping contaminants. The higher the filter’s MERV rating, the more effectively it works. Ratings are as high as 20, but these are reserved for specialized 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 typically more than sufficient for your home’s needs, but there are exceptions.

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

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 evaluating your indoor air quality needs and making the most suitable choice. Let’s compare the main benefits of an electrostatic filter:

Reusable and simple 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 added back in your HVAC system.

Long-lasting with regular upkeep: To work at their peak effectiveness, electrostatic filters should be washed every month. This is a short process that offers long-term benefits. Washable air filters are highly durable and can last the lifetime of your HVAC system when well 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 inferior. For your standard home, an electrostatic filter is a superb solution for removing airborne particles.
