Air Purifiers vs Air Filters

While both air filters and air purifiers clean the air, they are different products that serve various purposes. Every central heating and cooling system has an air filter, while air purifiers have an option for a filter. Here’s what you need to know about these products.

Air Filters

Air filters are installed in the return air ductwork in your home. They remove dust, dirt, pet dander, and other large particles to keep them away from your furnace and air conditioner. Their primary purpose is to protect your heating and cooling equipment, but they also keep dust and dirt from reentering your house.

There are different types of air filters for your central system. The least expensive and effective ones are made of fiberglass. There are also pleated ones that pick up more particles than fiberglass air filters can. There’s a limit to how thick filters can be, though, as there needs to be sufficient airflow through them so as to not damage the furnace and air conditioner.

Air Purifier

Air purifiers capture smaller particles than air filters can. They, too, are installed in the ductwork and can capture fungus, mold, and bacteria. These devices use filters as well, but their designs do not restrict the flow of air. Some use UV germicidal lamps as well.

Air purifiers can also capture smoke and smells. These negatively impact the quality of the air in your home. Air purifiers are installed because an air filter alone does not provide adequate filtration of the air.

These devices require little energy to operate. They also need less maintenance than air filters, which need to be replaced at least every few months during heating and cooling seasons.
