Does the air filter have to go a certain way?

The Arrow and Air Flow Direction



The arrow on your filter should always face the unit and away from the return air duct that carries the air that will be heated or cooled. HVAC systems push the cool or warm air out and pull spent air in, recirculating the air throughout your home.

Where should HVAC filters be placed?





Avoid storing spare air filters in a location where you would never think about them. Instead, store them in the laundry room or utility closet next to the cleaning supplies so you see them on a regular basis. Buy a whole stack at a time and label them with their intended installation month.

Does HVAC filter direction matter?

HVAC filter direction matters because air flows through it in one direction. While its two sides look the same, one is more porous to allow air to get inside. Otherwise, air can’t pass, and the unit itself must work harder and longer, leading to higher energy consumption and efficiency loss.

What happens if you put home air filter in backwards?

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.

How do you know the direction of airflow in HVAC?

Stand in front of the furnace and look for the ducts. Pull the old filter out and discard it. On the new filter, find the arrow indicating the proper airflow direction. The arrow must face toward the furnace and away from the return duct that pulls the air in need of heating or cooling.

What direction does air flow in a furnace?





If you are looking at a furnace filter, find the arrow that indicates the proper air flow direction. That arrow must always face toward the furnace and away from the return duct that carries the air in need of heating or cooling.

Why does my HVAC have 2 filters?

A lot of central air units have at least two filters, though you can find systems that have only one. The reason why there are a couple of filters is because not only the air that is traveling into the air handler needs to be filtered, but also the air passing through the return vents.

Can I use 2 filters in my furnace?

Bottom Line: Putting two air filters on a central air system will only have the net effect of producing a higher utility bill and reducing the lifespan of your central air unit. In short, the use of two air filters is just a BAD idea!

How do I change the air filter in my high ceiling?

Quote from the video:
Quote from Youtube video: Start by sliding the clips off to the side and slowly lowering the cover down next remove the old filter. You might notice a little bit of fine dust this is normal take the new air filter.

How do I know if my furnace filter is backwards?



Quote from the video:
Quote from Youtube video: You know there's an air flows indicator on here and what you want to do is just remember this is the furnaces filter. And that arrow always points towards the furnace.

Does it matter if furnace filter is backwards?

When a furnace filter is placed backwards, the fibers can’t do their job properly. This means your furnace has to work harder to generate the same air flow, resulting in increased energy costs. Particles are also allowed to build up irregularly, making the furnace working even harder to draw air.

Can a furnace filter be 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.

Does the arrow point up or down on an air filter?



Position the airflow arrow so that it points in the direction the air is flowing. In addition to clean air, filters also protect your HVAC system from debris and dirt buildup. The airflow arrow should point towards the furnace/blower motor to collect harmful particles before it reaches the furnace’s equipment.

Which side of furnace filter goes up?

Quote from the video:
Quote from Youtube video: The air is pointing this way the air will come down go through the filter. Pick up most of the dust.

Why are furnace filters directional?

The right furnace filter direction is necessary to effectively trap airborne particles. After removing the old filter, set it aside and grab your new filter. Check along the cardboard edges of the filter for an arrow. The arrow will indicate the air flow direction through your heating and cooling system.

Which way does Filtrete air filter go?

Quote from the video:
Quote from Youtube video: So you can see it says airflow there with an arrow. So if i put this in it's going to be backwards the airflow is going into this unit.
