‘No wonder my electric bill went up’: Homeowner issues warning against the ‘premium’ A/C filters at Home Depot

This is one of the few situations where something being cleaner is not necessarily better.

If you live in a house or apartment with central air (aka, the heating and cooling system integrated into your home), you're likely familiar with air filters.

Air filters help improve indoor air quality by trapping particles like dust, pollen, mold, pet dander, and bacteria. While these filters can benefit anybody, they're particularly important for people with allergies, asthma, or other respiratory conditions.
