Air Filtration vs. Air Cleaning: What’s the Right Choice for You?

Air Filtration vs. Air Cleaning: What’s the Right Choice for You?Many homeowners mistakenly believe that the air filter in their furnace or air conditioner, as long as it’s changed regularly, is all that’s necessary to keep indoor air clean and healthy. However, unless the air filter is a high-efficiency model, it’s not going to capture the smallest airborne particulates. Unfortunately, those are the ones most likely to exacerbate allergies and respiratory ailments in susceptible family members. For a comprehensive air-cleaning strategy in your southwest Oklahoma home, consider a high-quality air cleaning or purifying system.

The Limits of Air Filtration

You’re likely familiar with a standard HVAC air filter. Also called a furnace filter, this is usually a cardboard-framed, flat-panel filter that slides into a slot in the furnace plenum or A/C air handler. Before air enters the furnace or air conditioner, the filter removes a range of particulates. The main utility of basic air filtration is to protect the HVAC equipment from dust and debris. Higher-efficiency filters are available that can remove the great majority of airborne particulates, but they can be costly.

The dense filtration media required for a high-efficiency filter will likely restrict system airflow. This forces the furnace, A/C or heat pump to work harder to heat or cool your home. It wastes energy and stresses parts, hastening early repairs and replacement. Though the heating and cooling equipment can be customized to handle a denser filter, it can be expensive.

Try an Air Cleaner

Many households opt for a dedicated air cleaner or purifier, working as part of the forced-air heating and cooling system to complement air filtration. The best models employ multiple air-cleaning strategies in tandem to remove nearly all of the airborne contaminants, including bacteria, mold spores, dust mites and bacteria. Stand-alone air cleaners are available for limited areas, though for whole-house air cleaning, you’ll want a system that treats all of the air that circulates through your HVAC system.
