Harvest Right Pressure Release Valve Filter

This filter connects to an optional pressure release valve that attaches to the side of the freeze dryer where the vacuum hose is connected.  The Pressure Release Value is available from suppliers of the Harvest Right Freeze dryer.  

I cut ¾ inch squre from a cpap filter sheet and use the Vacuum Release Valve Filter cap 1.1 to hold it in place.
