Though an easy fix, it may never occur to you to change out the filter for your heating or air conditioning system. “Preventative measures like this can take just minutes to do but can help ensure your system is working efficiently and help save thousands of dollars in the long run from costly repairs,” said Brian and Mika Kleinschmit of American Standard Heating & Air Conditioning partners, who are the stars of HGTV’s 100 Day Dream Home. “Clogged filters are an added cost and ensuring your home has a clean one can save up to $30 a month. To maximize airflow and efficiency, and help your system operate correctly, replace dirty air conditioner filters monthly leading up to and throughout the summer months. This easy swap will decrease energy use and improve air quality.”

These pleated air filters are a cinch to install, trap tiny particles such as lint, household dust, and dust mite debris, and, to top it all off, cost less than $50 for a pack of six so you can expect efficient energy use and clean air flowing right into your lungs.
