Why Are Electrostatic Filters Better Than Regular Filters?

June 23, 2022

The air filter is a vital component of your HVAC system. It stops airborne particles like dust and pollen from circulating through your home. Figuring out what kind of air filter is right for you will help enhance your sense of comfort at home. For example, environmentally inclined homeowners could prefer an electrostatic air filter. Standard filters can’t be recycled and are usually replaced every couple of months. Instead, an electrostatic filter can be rinsed off and used again.

What Is an Electrostatic Air Filter?

An electrostatic air filter is distinct from media filters, which are nonreusable. Media filters are pleated and employ an extremely dense network of small fibers to trap 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 sucked into the filter and trapped. But because of the lack of fibers, electrostatic filters can be cleaned.

Washable air filters are suitable for people who hope to reduce waste. When kept in good shape, an electrostatic filter can last you a very long time. Meanwhile, your standard furnace air filter should be exchanged every few months. When furnaces can live 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 determine 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 average for residential air filters is between a 3 and a 6 MERV rating. These are generally more than sufficient for your home’s needs, but there are exceptions.

People with breathing problems or acute allergies may benefit from a stronger 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 specialized air filtration systems. Added filtration can 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 perks to using electrostatic air filters in your home. It just depends on reviewing your indoor air quality needs and making the most suitable choice. Let’s compare the principal benefits of an electrostatic filter:

Reusable and easy to clean: Compared to pleated media filters, washable air filters are recyclable and reusable. All you have to do is thoroughly rinse them off. Wait 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 provides long-term benefits. Washable air filters are highly resilient and can survive the lifetime of your HVAC system when well cared for.

Offers quality layer of protection: While HEPA filters or dedicated air filtration systems can offer solid results, that doesn’t mean other filters are substandard. For your typical home, an electrostatic filter is a great choice for getting rid of airborne particles.
