Electrostatic furnace filters are becoming very popular with home owners who want to achieve adequate air filtration and avoid using disposable filters. These air filters are designed to replace any type of panel filter or frame type air filter you currently use in your heating and air conditioning equipment.
Electrostatic furnace filters are a combination of mechanical air filtration and electrostatic filtration. Like the technology used in many of the air cleaners commonly sold today which remove dust particles from the air by using static electricity or electronic means.
Some of the Pros and Cons of Electrostatic Filters
|No need to buy new filters because they are reusable.||Must be removed and cleaned monthly.|
|They do an adequate job of air filtration.||Not as efficient as most pleated filters.|
|Save money.||Not ideal for those who suffer from allergies.|
|About as efficient as a pleated filter with a MERV 5 or 6 rating.||Cheaper brands can have a negative impact of equipment performance.|
|BoAir are among the best electrostatic filters available and can be purchased on Amazon|
Why Use Electrostatic Filters
When selecting a filter for your heating or cooling system it only makes sense to use the most efficient filter possible. An air conditioning or heating system operates best with no restriction to air flow. Adding a filter to to any HVAC system restricts this air flow and therefore can reduce the operating efficiency of the equipment.
The best furnace filter is the one that has the least effect on air flow but removes the most dust from the air. This is where the electrostatic furnace filter shines. They remove a high percentage of contaminants from the air but at the same time have little effect on air flow.
This allows the equipment to operate at maximum efficiency while at the same time removing a high percentage of contaminants from the air. So the best you can hope for is to strike a balance where you get the best air filtration but also don’t restrict airflow to the point where it begins to have a negative impact on the operating efficiency of the system.
The Best Air Filter For Home Use
Electrostatic furnace filters are not the most efficient filter you can get for your central air conditioner or furnace. But remember, you want to strike a balance between filter efficiency and equipment performance.
There are many furnace filters that are more efficient than electrostatic filters. The most common is the pleated air filter.
The BoAir 5 Stage electrostatic filter is one of the best electrostatic filter available. They have a lifetime warranty and never need to be replaced. They don’t contain polyester, which becomes difficult to clean over time. BoAir electrostatic filters are the only ones embedded with VIBAX MI-50, an anti-microbial which, limits and controls bacteria, mold, mildew, and helps control odor.
How Does An Electrostatic Air Filter Work
As air passes through electrostatic filters, a static charge is created within the filter, as a result of this static charge dust particles are attracted to the filter and remain trapped there until the filter is washed.
The air you breathe contains many allergens and irritants such as dust, bacteria, mold spores, pet dander, pollen and smoke. Most of these particles are smaller than one micron in size and will pass through cheaper furnace filter. When you install an electrostatic furnace filter the number of particles passing through your heating or cooling system and returning to your living space will be reduced.
An electrostatic air filter will save you hundreds of dollars by eliminating the monthly cost of purchasing disposable filters. Typical disposable fibreglass filters are only 5 – 10 percent efficient. The best electrostatic air filters may be as much as 90 percent efficient.
