A good filter for your furnace is a must. Because that device heats and blows air throughout your Chelmsford home, you want to be sure that it doesn’t recycle contaminants and bacteria that could easily be captured at the air handler. That’s why it’s vital to choose the right furnace filter on the first try. Here are some furnace filters to consider and their various benefits to your home and family:
- Electrostatic – Most electrostatic filters are permanent and must be washed on a regular basis. They are electronically charged to capture particles as they pass through, much like a magnet. These filters are effective because they are both physical and electronic. However, keep in mind that they are only as efficient as the cleaning they receive.
- HEPA – HEPA is the highest rating available for a filtration system, removing up to 99.9% of all particles as small as 0.3 microns. However, they are also inefficient when used in furnaces as they severely reduce air flow. They are not often recommended for this reason.
- Pleated – Pleated filters come in both reusable and permanent forms and can be either purely mechanical or electrostatic. There is a very wide range of efficiency ratings for pleated filters so make sure you analyze your home’s specific needs before selecting any one pleated filter.
- Activated Carbon – Activated carbon is unique from the other three filter types because it effectively removes fumes, odors and chemicals from indoor air along with other larger particles. It is recommended that if you choose an activated carbon filter, you supplement it with a pleated or electrostatic filter (or choose a combination filter) to remove all unwanted components from your home.
There are a lot of options when it comes to furnace filters. To make sure you get only the best air quality, talk to a Chelmsford heating professional who can help you determine which pollutants are the biggest problem in your home.
