Bad Air in, Clean Air out: On Furnace Filters

Furnaces are appliances designed to warm the air inside a building, and they do this by taking in air and running it through a series of heaters. Once the air gets warmed enough, it’s then pumped back into the building through a series of ducts. Crucial to this system is the air filter, which prevents particulates from entering the ducts and assembly.

The importance of air filters within furnaces can’t be stressed enough. The dirt and contaminants that filters catch can potentially harm the respiratory systems of people who inhale them. Worse, if dirt is allowed to circulate around the assembly, it could clog some parts and lower the performance of the system. Dirt doesn’t even have to pass through a filter to hamper furnace performance; if the filter has collected enough dirt, the latter can block out a portion of the air current.

Homeowners should remember to occasionally clean their furnace filters to prevent such problems. Filters also need to be changed if they’re showing signs of damage and can’t properly catch dirt. Replacements are quite affordable, and come in numerous sizes. It will be a tedious job to do either of the tasks mentioned, yet homeowners can simply hire contractors to perform these tasks for them.
