This large (50mm diameter) HEPA air filter has a glass micro fiber filter element, and is rated at 120 hours of use before clogging. Rated to be 99.97% efficient at blocking particles .2 micron in size or larger. What this means is the air going through it will be essentially sterile when it comes out.

The glass micro fiber element will last for several hundred uses with proper care. Designed by us to perfectly fit standard aquarium air pump tubing. Autoclavable.

This filter will also fit any of our bored rubber stoppers (the stem is stepped to fit anything from fish tank tubing to 3/8" interior diameter tubing) to be used in place of an airlock. Other uses include filtering incoming air when hand pumping beer. See also our Foam Stoppers (link below) for a good airlock alternative.

Is it important which direction gases pass through this filter? In other words, if I am installing it in a gas line, should I orient it in a particular direction?
No, this filter does not have a preferred direction.
