Forum:Vault 22 help please! HEPA air filters location?

Ive been stuck in vault 22 for like 2 hours roaming around.

I have the card key that you get from the living quarters. Now where do i go? My quest marker tells me to go to a door, then when i go to the door it tells me to go directly back into the door i came from. I unlocked that door that the people living here before locked and I unlocked everything in the over seerers office.

There is a tunnel that is blocked of thats in the caves, is this where i needed to go?

-Someone please answer? I am stuck here as well. On one of the levels is a keycard on a desk next to a working terminal. Use that keycard on the sealed door into the cave via the terminal to the left. Follow the tunnel until you reach a door saying like Oxygen Purification level or whatever. Enter there and you should get it.

-I Got into the Oxygen Recycling level, but both of the lockers are empty. What do i do now?

= Answer = Get to the elevator on any level, and use it. Go to Food Production. Once you arrive on the floor, walk east. There will be a terminal to unlock a door into the caves. Once you enter the caves head south until you find a door. It will lead back to the Oxygen Recyling Level on the other side of the blockage. Open the lockers in this room and you will find 6 "HEPA 20 Cartridge Filters"

- I just wanted to add that the lockers said "empty" however if you search them anyway you will find the HEPA cartridges.
