Electronic furnace filters are different from most other air filters because they use electricity to remove dust from the air. One of the biggest benefits of an electronic furnace filters design is that they create very little restriction to airflow.
One of the potential problems of very efficient air filters is that they can sometimes cause air conditioning and heating equipment to operate erratically or even lock out on safety controls. This is because they tend to have a greater impact on airflow than filters that are less efficient.
If you suffer from allergies and want to remove as many allergens from the air in your home as possible, you may want to consider electronic furnace filters. These filters are usually rated over 95% efficient and cause very little restriction to airflow.
The smaller particles pass through the pre-filter and are electrically charged as they pass through the second section of the electronic furnace filter. Collector plates, located in the third section of the furnace filter, attract these smaller particles.
As air passes through electronic furnace filters, the first section it comes in contact with is the pre-filter. The pre-filter is designed to capture larger particles and is not very efficient. It will not stop smaller dust particles.
The electronic furnace filters collector plates have to be removed and cleaned every three to six months. Although these filters require regular maintenance, they are a good alternative to inefficient disposable furnace filters. They are also a good option to improve indoor air quality without having a negative effect on airflow.
