The Benefits and Risks of Using an Electrostatic or Non-Electrostatic Merv 8 Filter in Your HVAC System

Air filters are an essential part of any HVAC system, as they help to keep the air clean and free of pollutants. However, not all air filters are created equal, and some may even pose a health risk if not used properly. In this article, we'll explore the advantages and disadvantages of using an electrostatic or non-electrostatic Merv 8 filter in your HVAC system. The most common type of air filter is the fiber filter, which is composed of fibers that attract particles and collect them on the surface as air passes through.

This can cause blockages that will eventually make it difficult for the air conditioning system to blow and extract air. Particles also become a health hazard as they accumulate, as they can enter along with the air and produce bad odors. Exposure to indoor air pollutants has been linked to serious health effects, such as asthma, respiratory irritation, and cancer. Some devices advertised as air purifiers intentionally emit large amounts of ozone, the main component of smog.

The California Air Resources Board (CARB) recommends that ozone generators not be used, except for approved industrial purposes where harmful exposure to ozone is avoided. Not only are ozone generators ineffective at cleaning indoor air, but inhaling ozone poses serious health risks to humans and animals. Advantages of Electrostatic Filters An electrostatic filter is a type of air filter that uses an electrical charge to attract particles. As the filter is made of metal, it is reusable, so it is not necessary to change it every few months, as is the case with a normal filter.

This makes them an ideal choice when it comes to cost-effectiveness and longevity. The particle is trapped before releasing its charge as the air passes through subsequent layers of the filter. According to the Environmental Protection Agency (EPA), most mechanical air filters trap large particles such as dust, pollen, and animal dander well. Air filter quality is measured with minimum efficiency values (MERV) and is used to indicate the filter's ability to capture larger particles between 0.3 and 10 microns, meaning that the higher an air filter's MERV rating, the better it will filter the air.

Potential Health Risks Manufacturers of heating, ventilation and air conditioning systems have been testing the effectiveness of filters in protecting people from contracting the virus. It is recommended to replace them with a higher efficiency filter, since these filters are not effective in removing contaminants. If family members suffer from allergies, it is recommended to use an air purifier in addition to frequently cleaning the air conditioning filter. Don't wait until you have to deal with an air conditioning system malfunction to determine if it's time to replace an electrostatic filter.

The Bottom Line If you want a well-functioning coronavirus HVAC filter, you need to make sure it's properly installed and maintained. Your heating, ventilation, and air conditioning system is there to maintain a comfortable temperature in your home, and your filter is part of the process. Regular inspections of your electrostatic filter can help you have equipment up and running in your home.
