Which Way Does Air Filter Go In

Which direction does the arrow on an air filter go?
Which way does air filter go in. Thank you for using manage my life. What way does a furnace filter go in?. But if your filter is installed in the wrong direction (a mistake that can be made quite easily), the performance and efficiency of your system will suffer.
If caked on dirt and dust are falling off the surface, it’s probably restricting air flow and you’ll want to take action. Most filters have arrows on the frame of the filter that indicate which direction the filter should go. Well, the most direct answer is:
For any air filter, whether it be for an air conditioner or a furnace, the arrows always point in the direction of air flow. I can understand wanting to know which direction to install the filter. Sometimes when you pull out the filter, it’s painfully obvious whether it’s time to clean or replace:
Remove the air filter from its housing. The air filter box or simply air box is not that difficult to find. This makes sense as the air is drawn in from the base of the windshield, through the filter and to the fan.
The next question is always.well, how can i tell which way the air is flowing? In either case one side has a metal screen of one sort another this is the side that goes towards the unit. If the air is not flowing, briefly turn the fan on to verify the direction.”
With 99% of installations, the filter is on the cold air return side, generally on one side of the furnace, or even inside the furnace compartment. In fact, energy.gov reports that replacing a dirty, clogged air filter with a clean one can lower your central air conditioner or furnace energy consumption between 5 and 15 percent! The mesh fits inside a plastic housing on the inlet side of the unit to prevent dirt from collecting on the cooling coils.
