An excellent and effective air filter is an essential fixture for your home, especially if you’re living in Florida. Your primary choice is a regular replaceable air filter or a washable electrostatic filter. In this post, you’ll about how regular and electrostatic air filters work and why installing electrostatic air filters is a great way to enhance indoor air quality.
What Is an Electrostatic Air Filter
Like other air filters, an electrostatic air filter aims to clean the air flowing via your home, lessening the number of allergens and pollutants circulating within your home while protecting your HVAC system from dangerous debris. However, unlike other air filters, electrostatic air filters utilize electromagnetism to drag particulates from the air.
Think of electrostatic air filters like magnets. There are two distinct poles at each end of a magnet. If you’ve ever tried to keep two like poles together, you will observe that they repel each other. Similarly, when two opposing poles come close, they attract one another.
Electrostatic air filters work likewise to dust magnets, using static electricity to draw dirty air and ensure it sticks to the filter. Coarse fibers of the filter are electrostatically charged and gather particles over time.
The filter’s effectiveness dwindles as more particles build-up, but a thorough cleaning can relieve that issue. When washed and maintained regularly, these filters can last for a long time.
Air Filter Effectiveness
Filter effectiveness is evaluated on the minimum efficiency reporting value (MERV) rating specified by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).
This rating is defined by the size of particulates a filter can entrap. MERV ratings can vary from 1 to 20, with lower ratings less efficient than higher ratings. Furthermore, it’s important to note that the more complex an HVAC system has to push air through the filter as the rating increases.
Most residential air filters are rated between 1 and 12, with filters rated 13 or higher considered hospital-grade as they might require a specific HVAC system.
Regular vs. Electrostatic Air Filters
The most common air filters are considered mechanical because they physically block pollutants from penetrating your house, unlike electrostatic air filters, which depend primarily on static electricity to entrap particles.
These filters generally have MERV ratings between 1 and 4, meaning they can handle large debris easily but struggle to filter smaller allergens and pollutants. Sadly, these air filters must be replaced every 30 to 60 days, and the cost of replacement filters can accumulate quickly.
By comparison, electrostatic filters usually have MERV ratings of between 8 and 10 and are more effective at clearing air particles than regular disposable air filters. These filters do a remarkable job of protecting your HVAC system from enormous debris and can improve indoor air quality. Unlike disposable air filters, electrostatic air filters are reusable after washing and save you money in the long run.
HEPA Filters vs. Electrostatic Air Filters
High-Efficiency Particulate Air (HEPA) filters usually have a MERV rating of 17 to 20 and can eliminate up to 99.97% of airborne contaminants. HEPA filters are very efficient at improving indoor air quality and even lessening harmful pathogens. Often deployed in hospitals, HEPA filters are less likely to be installed in residential neighborhoods because of their cost. Nevertheless, they can dramatically improve your quality of life if you suffer from allergies or have respiratory issues.
While they’re not as effective as HEPA filters, electrostatic filters still do an excellent job filtering the air and guarding you against harmful contaminants. Because they’re reusable, the cost savings gained from installing permanent electrostatic air filters can be tempting, especially if you’re not sensitive to the airborne particles that HEPA filters stop.
Pros & Cons of Electrostatic Air Filters
1. Good Filtration: Electrostatic air filters are more effective at filtering airborne particles than standard disposable air filters.
2. Highly Efficient: Electrostatic filters efficiently filter most harmful pollutants from the air without making your HVAC system work hard to push air through a wide filter.
3. Cost-Effective: Washable air filters have a higher initial price than regular disposable air filters. However, they recoup the cost soon as you never have to replace them.
1. Regular Maintenance: These filters must be thoroughly cleaned monthly to maintain their effectiveness.
2. Less Effective for Asthma and Allergies: Though they can filter out most airborne contaminants, electrostatic air filters are unsuitable for people with severe allergies or respiratory problems.
3. Lower MERV rating: While electrostatic filters are effective, disposable air filters can be more effective—HEPA filters have a MERV rating of 16.
The metal filter can be detached from the blower component and cleaned with a hose. The filter will take around 15 to 30 minutes to dry. Do not reinsert a damp filter into the blower component after cleaning. The airflow will pull the moisture from the filter into the ductwork.
Mold needs two things to grow; moisture and organic material, such as dust. Avoid putting moisture in your ducts. Running your HVAC system without a filter while drying your electrostatic filter is also inadvisable. Keep this in mind and turn the system off during washing and drying; be careful not to wash during extreme weather conditions.
We can’t overstate the importance of having good air quality. And, when it comes to selecting the proper type of air filter for your home, it makes sense to use the most energy-efficient model. Electrostatic filters provide you with precisely what you need.
Electrostatic air filters have a minimal effect on airflow while remaining successful at removing contaminants from your environment. They’re one of the best types of air filters on the market to remove debris, dust, and other allergen and contaminants. You deserve to have the cleanest air possible! When your indoor air quality is high, you and your loved ones will reap the benefits for years to come.
Also, keep your house clean at all times. A clean house can significantly cut down on dust & pollen. If someone in your house suffers from asthma or allergies, vacuum carpets, and area rugs once a week.
