Truth Revealed: Should You Really Invest In Electrostatic AC Filters?

Many people have trouble with dust throughout their homes, even when using the proper measures in cleaning their air filters and purchasing the best quality equipment or HVAC. There are a few truths to know about the positive, as well as the negative, attributes of electrostatic AC filters.

Most conventional AC filters are simply engineered cotton and wire frame pass-through filters used in older HVAC systems. These are usually throw-away filters and filters that need to be cleaned every other month or more depending on the air quality of the environment.

These filters usually produce a CADR of 50 cfm, which means that they are 50% efficient in producing clean air quality after inflow is pushed through the air conditioning unit.

The Positive Attributes of Electrostatic AC Filters

Electrostatic filters provide a higher efficiency percentage than conventional filters – this is a known fact amongst industry professionals. The technology and engineering behind the filter is that it actually attracts dust particles in the air and force the particles towards metal, hence the electrostatic nature of the material. Like any static connection, the dust particles are electrified and magnetized towards the machine used to filter the air through the intake. This provides a higher quality and efficiency than conventional filters because the intake flow using conventional filters does not magnetize the protons in the dust particles and therefore the filter only filters what is given through the sucking of dust in the air intake system. This leaves dust in hard to reach places intact and ultimately causes build up throughout the house.

Electrostatic filters, particularly throw away filters, are much more efficient in grabbing dust particles throughout the home and transferring them through the intake and into the system.

It’s Not All Good and Cozy With Electrostatic

One of the most prevalent issues with electrostatic filters is the chemical discharge they produce from usage. Some of the machines that use electrostatic filters also produce ozone, a chemical that oxidizes the surface of your home and is harmful to breathe. Not all of the machines and systems create this, so it’s important just to research prior to installation.

Another negative attribute to charging dust particles is the effectiveness of the charging. By charging dust particles, attraction occurs throughout the house and all surfaces become a target for deposition markings. If you start seeing black markings on various surfaces throughout your home, you may want to change your filter.

Check the Performance Standards

On every air filter packaging you will find performance standards and efficiency percentages. As a consumer, you want to look at the percent efficiency of filtration and the amount of air filtered per minute, as I stated above. The cfm is the important number to study, as a higher cfm number means higher cubic feet per minute of air filtering through product. The efficiency of filtration simply refers to how many particles are being filtered when the air is cleaned through the device. The higher this number, the better off you will be.

Electrostatic filters will have a higher efficiency and cfm rating, but use with caution and notify the company if you see black markings on walls and ceilings
