The air filter might be on top below or on the side of the air handler depending on what kind of air handler you have.
Attic ac filter location.
This allows the filter to clean the air coming from your house before it enters the hvac unit.

The air filter is usually located in the return air duct or blower compartment before the return air reaches the air handler.
The air handler is the large metal box containing the fan and fan motor.
An outdoor unit which houses the fan condenser and compressor and an indoor unit which holds the evaporator and fan.
It s generally located in your attic basement closet or crawlspace.
So why put an hvac system up in the attic at all.
Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts.
Attic hvac systems save space.
And those bedrooms are a cool 72 degrees at bedtime even on the hottest day of summer.
That same ac system that could never cool your bedrooms now with a sealed and insulated attic is providing supply airflow temperatures on par with the same unit located under a house.
This air handler has a filter base under the unit.
All central heating and cooling systems should have an air filter but the filter can be harder to locate on some hvac units than others.
The condenser in your air conditioner works hard to get rid of heat and pressurize refrigerant for the return trip through your house.
Changing the filters in the hvac unit in this case your air filter is most likely located right next to your furnace or air conditioning system air handler.
