What happens if you install air filter backwards?

Why do air filters have arrows?

The directional arrow points in the direction of the airflow which is into the return duct. The filter is installed with the arrow facing into the air return.
How does a blower fan work?
The blower fan turns on and begins blowing air towards the supply ducts. As the blower is running the fan draws air from the return duct. Thus air flows from inside the house across the evaporator coil located inside the air handler. The air is heated or cooled before it flows into the supply ducts and then back into the house.
