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 type of air filter is right for you will help improve your sense of comfort at home. For example, environmentally inclined homeowners could opt for an electrostatic air filter. Regular filters can’t be recycled and are normally replaced every couple of months. Instead, an electrostatic filter can be washed off and used again.

What Is an Electrostatic Air Filter?

An electrostatic air filter is different from media filters, which are nonreusable. Media filters are pleated and employ an extremely dense network of small fibers to capture airborne particles. While this design is effective, sooner or later 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 absence of fibers, electrostatic filters can be cleaned.

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 standard 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 away.

Do Electrostatic Air Filters Have a MERV Rating?

The MERV rating system is a great way to determine how effective an air filter is at catching 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 usually 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 eliminate up to 97% of airborne particles, keeping indoor air quality very high. These filters are regularly found in dedicated air filtration systems. Added 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 benefits to using electrostatic air filters in your home. It just depends on evaluating your indoor air quality needs and making the ideal choice. Let’s review the key advantages of an electrostatic filter:

Reusable and simple to clean: Compared to pleated media filters, washable air filters are recyclable and reusable. All you have to do is properly rinse them off. Give 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 maximum effectiveness, electrostatic filters should be washed each month. This is a brief 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 quality 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 standard home, an electrostatic filter is a great choice for removing airborne particles.
