What kind of air filters are out there? There are two main groups of air filtration systems out there; mechanical filters and electronic filters. However there are also many categories of each group and it can be rather helpful finding out what the difference really is between all of them.
Mechanical filters operate on the premise of trapping particles and creating a physical barrier between your furnace and the rest of your home. Of the mechanical filters you have the following types.
- Flat Filters – tend to catch only larger particles however have limited impact on air flow
- Pleated Filters – excellent at catching small particles but at the cost of air flow
Electron filters differ from mechanical filters as there is no restriction of air flow. These filters operate by giving a static charge to particles so they cling to mesh or duct work instead of blowing into your home. Not all electronic filters are created equally however. Some are known to generate ozone which the EPA recognizes as potentially harmful to your lungs.
Often times we find a hybrid approach to air filtration is the best method to providing you and your family with save air. However we recommend a free home estimate to help you find what solution is right for you.
