Which way does air filter go in furnace?
Slide the new filter in with the arrow pointing toward the furnace. Replacing your air filter is not difficult. Remember that air flows from your ducts, through the filter, and into the furnace. The arrow on the filter should always point toward the furnace.
What happens if you put a furnace filter in backwards?
If the furnace filter is installed backwards, the fibers won’t properly filter the air which can eventually cause damage to the unit. It also will diminish airflow through the furnace causing it to work harder and use more energy.
What side is the air flow direction for a filter?
Air filters have arrows printed on the sides of them that show you which way they are supposed to be installed. These arrows should be pointing in the direction that air flows through your system, which is away from the supply ducts and (typically) toward the blower.
What happens if air filter is upside down?
By installing your filter backwards, air will have a harder time flowing through the filter and your air handler will have to work harder to make up for the loss of airflow. This could lead to higher utility bills and possibly damage your furnace or air conditioner.
What is the direction of air flow?
Air always flows from a high-pressure area to a low-pressure area, much like water running downhill. Therefore, without an effective barrier, air outside a home at a higher pressure will always attempt to enter the home.
Which side of furnace filter should be dirty?
The dirt should not be accumulating on the metal mesh side of the media; if that is happening, you put it in wrong. Switch it. The mesh side is the back side ; the air should flow through the front side first.
Which way does the air flow through my furnace?
Air flows through a furnace one of three ways: up, down or horizontally. A downflow furnace takes in cool air from the top, warms it, then releases the warm air at the bottom and pushes it through the ductwork below. Upflow furnaces, as you may have guessed, work the opposite way.
Which direction does the filter for a furnace go?
Most filters have arrows on the frame of the filter that indicate which direction the filter should go. The arrow points in the direction the air is flowing through the duct system. Most furnace filters are bi-directional (does not matter which way the air travels).
What is the best type of filter for a furnace?
High efficiency pleated filters are the best air filters you can use in your furnace. Their design uses electrostatically charged fibers to attract and hold dust, allergens and even tiny smoke particles.
How do I find a filter for my furnace?
To locate your filter, start at the air handler and trace the ductwork back towards the furnace until you find the filter. In particularly new furnace systems, the return air grill itself may be home to the filter, sealed at the edges completely to keep airflow contained.
