# Spray the top of the filter with the water spray bottle. It doesn't need to be soaking, just damp is fine. The idea is to wet the dust so it stays put as you handle the filter.
# Lift the top filter frame out of the filter box and get the garbage bag ready.
# Starting at a short end of the frame, pull the filter material out of the edges of the frame and roll the filter up as you go
# Put the dirtied filter in the garbage bag and tie it up. Put that garbage bag into the big trash can in the main lab.
# Selecting the correct filter size, lay the filter material down in the frame '''with the blue ink lettering downward'''. When it's in the correct orientation there will be no wording visible to you.
# Carefully snug the edges of the filter all around the filter frame to make a tight seal. There shouldn't be a way for air to pass through the frame without going through filter material. Any air gaps here will cause a problem.
