How To Select The Best Electrostatic Air Filter For Your HVAC System

Choosing the right Electrostatic Washable Air Filter depends on a number of features. Such as:

1. MERV Rating

Unless clearly written, most electrostatic washable filters are not really rated. However, that doesn’t mean they don’t have one. Anything from 4/11 is usually the overall Merv you will find. The thickness of the frame could vary up to 1/ 8 and still filtrete clean air.

MERV ratings commonly run on a scale of 1-20.

The higher the number, the more effective the air filter is, and the more types of particles it can remove from the air. However, if the MERV rating gets too high, it can block airflow, which can reduce your ventilation system’s overall performance.

For this reason, we recommend sticking with a MERV rating of 13 or lower. Air filters within these MERV levels remove the majority of the dust from your home without compromising your system’s performance.

2. Design

Electrostatic Air Filters are designed to use the naturally occurring phenomenon of static electricity to capture air particles. While a standard air filter performs sufficiently to filter larger air particles from the air, they fail to grab some of the smaller particles.

3. Size

An important thing to note before purchasing an electrostatic air filter is the size of your furnace. You’ll need to measure your furnace dimension before buying an air filter. All of this preparation will help you save time and look for the exact filter or nearest in meter size.

Filter sizes come in two types. But nearly all filters go by the nominal size. Pay attention to the actual versus the nominal air filter sizes. Nearly all filters go by the nominal size, which is the actual size rounded up to the nearest inch measurement. Both sizes are usually written on the side of your air filter. But if you can find it, grab your tape and measure it before pressing that buy button.

4. Energy Efficiency

The wrong air filter in your HVAC System can add excessive pressure to the components. When a filter becomes extremely clogged, airflow through the filter begins to slow, which can force an HVAC system to work harder to compensate.

Electrostatic air filters are engineered to reduce airflow resistance, extending the life of your HVAC system and delaying replacement for a long time. High airflow helps reduce HVAC system strain and requires less energy, which can translate to savings for you!

5. Cost

In general, know your budget before buying an electrostatic air filter. A clear budget will get you the right filter. The average electrostatic filter cost between $30 – $60 dollars on Amazon. However, you may incur more costs when you ship to your location.

Make sure you purchase air filters within your price range that can guarantee the best performance and value.

Best Electrostatic Air Filter FAQs

Buying an electrostatic air filter can be stressful, but we hope this guide has provided you some assistance. If you still need additional information, our frequently asked questions below would be of help 

  • How does Electrostatic Air filters Work?

Electrostatic air filters drag allergens out of the air using static electricity. These charged particles are magnetically pulled to the metals in the air filter, rather than staying in the air that you breathe.

Unlike fiberglass or cotton pleated filters, electrostatic air filters are effective at capturing over 80 to 90 percent of dust, pollen, pet Sanders, smokes, and mold spores in your home.

Electrostatic air filter function under two categories such as:

1. Electrostatic pleated air filters

They combine components of paper made pleated air filter mixed with elements of washable electrostatic air filter for effective filtration. While they are very efficient in catching larger dirt particles, they don’t last long as washable air filters.

2. Electrostatic washable air filters

As stated earlier, they use static electricity to capture allergens. They are reusable and cost-friendly. 

  • How Do I Install the Electrostatic Air Filters

Installing the electrostatic air filter is quite easy. Most filters are flexible and can be fitted to your HVAC system from either side of the frame, while others are fitted the same way you would install a traditional filter.

To install, check the air filter to find an arrow at the top. The arrow should point towards the direction of your furnace, as this is where the air flows from. Then, determine which position your filter needs to face and insert it into the opening. For filters with metal construction and tight ends, you may need a little pushing or tapping when inserting in the slot.

  • How Do I Clean My Electrostatic Washable Filter?

For the best results, we advise you to clean your electrostatic reusable filters once a month. If properly cleaned, the lifespan and effectiveness of the filter will be maintained, providing you with a clean breath that will last you for years.

To clean, rinse with a hose to remove the clogged particles. But for heavy dirt, soak the filter with mild detergent, then rinse thoroughly with clean water. Make sure the fluid dries up completely before reinstalling into your system.
