Why Are Electrostatic Filters Better Than Regular Filters?

June 23, 2022

The air filter is a key component of your HVAC system. It prevents airborne particles like dust and pollen from circulating through your home. Finding out what sort of air filter is right for you will help enhance your sense of comfort at home. For example, environmentally minded homeowners might prefer an electrostatic air filter. Typical filters can’t be recycled and are normally replaced every few 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 thick network of small fibers to capture airborne particles. While this design is effective, eventually 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 suitable for people who want to reduce waste. When kept in good shape, an electrostatic filter can last you a very long time. Meanwhile, your traditional 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 tell how effective an air filter is at collecting 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 problems or severe allergies can 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 commonly found in specialized air filtration systems. Added filtration could also be beneficial for the elderly and people with respiratory ailments.

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 review the main features 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. Give 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 provides long-term benefits. Washable air filters are highly durable and can last the lifetime of your HVAC system when properly cared for.

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