When it comes to deciding on the type of air filter to use in your home, one factor tends to play the largest role in decision making: cost. Every homeowner wants to save money wherever possible. Those looking for ways to save are excited to hear about Electrostatic or washable air filters. Although the concept is great and cost is relatively low, Electrostatic filters are not necessarily the best option for you home.
One positive washable filters have over pleated filters is they don't have to be replaced as often. You simply vacuum and rinse. They cost between 50 and 60 dollars--what you could easily spend on traditional filters in just a few months. This alone is enough to convince many homeowners that electrostatic filters are the way to go. Although the super low price is very appealing, they can lose their electrostatic charge over time and there are other important factors that can outweigh the cost benefits.
Electrostatic filters are composed of multiple layers of vented metal. As air molecules pass through the first layer, they become positively charged by the friction of the air on the metal. Dust and other pollutants then attach to the other layers as they pass through the filter toward your system.
Improper filtration can lead to high repair costs or system failure! Pleated air filters can filter more from your air, while putting less strain on your system. You may be paying more in the long run, but you'll rest easy knowing that your air is actually clean and that you aren't slowly harming your HVAC system.
