Which Way Do Air Filters Go. Luckily most filters are made so they wont fit right unless theyre inserted in the correct direction. Air filters may have an arrow on the frame that shows you in what direction the filter should be inserted into the furnace.
THE ARROWS ON ANY AIR FILTER NEED TO POINT IN THE SAME DIRECTION THE AIR IS FLOWING. The Arrow and Air Flow Direction To properly insert a new filter look for the arrow. Some filters have a cardboard or mesh face on one side that indicate a sturdier design so the filter would be installed with the less sturdier side facing towards the air flow so it filters through that side first.
Are you too laz.
HVAC systems push the cool or warm air out and pull spent air in recirculating the air throughout your home. This means the side with the wire-frame will be on the outside or the side closest to you and the side without it will be inside closer to the unit. Not sure how to change a filter in your home. So be sure to look for the arrows that are printed on the sides of the filters because they show you which way the filters are supposed to be installed.
