A furnace air handler, also called furnace filter box, is designed to keep the furnace filters clean and avoid them clogging up. The furnace filter is one of the most important parts of the furnace because it holds the coolant that provides heat. Over time, the dirt build-up in the filters can lead to a condition called carbon monoxide poisoning. Carbon monoxide is highly toxic and can cause serious health problems in extreme cases. Since the filters are made of aluminum, it is easily corroded. It can also gather dust particles, hair and other debris that make its way into the cooler or the thermostat, causing malfunctioning or fire.
Furnace air handlers are designed to help prevent this buildup of dirt and debris. A high quality filter is the best solution to this problem. If you have a standard furnace, you only need a regular filter. But if you have a more efficient furnace, you will need a HEPA filter that will remove most harmful particles from the air. There are various brands of furnaces that come with different sized filter boxes and the ones made by different manufacturers differ in their specifications and features.
An air purifier is a very effective solution to this problem because it helps remove many contaminants and particles that can cause health problems, such as mold and mildew, lead and other heavy metals, as well as dust and other impurities. If you have a very large furnace or one that is very old, you may need a charcoal air filter for removing these particles. You can buy this type of filter online. If you do not have a fireplace, you can use an outdoor air cleaner that has a hose attached to it. This unit will remove dust particles that are settled on the outside of your house or chimney.
