Which way does the air filter go?
To properly insert a new filter, look for the arrow! 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.
How long is a filter supposed to last?
Fiberglass filters are a lower cost option, but they need to be disposed of and replaced roughly every 30 days. Pleated air filters are usually made of higher quality materials and can last anywhere from three to six months depending on the material, manufacturer and the frequency of use.
Do filters last forever?
Reusable Filters Don’t Last Forever In some cases, this is true. A good, sturdy reusable filter that is well maintained should last you a couple of years. In reality, however, wear and tear along with caked-on dust will cause a reusable filter to lose some of its efficiency in a matter months.
Can you put a furnace filter in the wrong way?
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.
Which is way does my air filter go?
If there’s no arrow on the filters, make sure the metal mesh is facing the HVAC blower. If the air passes under and through your filter, the mesh side will face upwards. Reply
What happens if you don’t change your air filter?
You can experience even worse problems if you don’t change your air filter at all. Your air filter can collect a lot of dust, so it’s a good idea to always turn off the power to your furnace since you don’t want to suck up the dislodged dust into your unprotected HVAC system. In most instances, your filter is located near your furnace.
What happens when you put a filter before a fan?
Now we’re not 100% sure on this, but based on research on guide vanes, putting a filter before the fan will make the air going into the fan turbulent. Making the fan operate in turbulent air flow (as opposed to laminar flow) has two consequences: A. The efficiency of the fan is reduced. B. The fan will be noisier.
Why are some air filters more porous than others?
That’s because air filters are designed with one side that is more porous than the other. This allows the filter to effectively trap airborne particles while also minimizing the chances of slowing down your system’s airflow.

Why are filters used in an air conditioner?
Air conditioning filters trap dirt, dust and pollen to help keep air cleaner. Furnace and air conditioner filters are important devices for helping to remove dust and pollutants from the air in your home, and are often designed to have air flow through them in a particular direction.
