Setting up the Covidisor

Connecting the Filters

1. The front two filters use a three prong “bayonet” mount. One of the prongs is smaller than the other two. Match the smaller prong in the mount with the smaller opening in the back of the filter.
2. Press the filter in slightly and rotate it clockwise until you hear a click (about 45 degrees).

Connecting the fan

1. The white round filter in the back of the Covidisor is the exhaust filter.
2. To connect the fan to it, first orient the Covidisor so the back filter is facing up then connect the fan to it by rotating it twice. No need to tighten it.

Putting on the Covidisor

1. Place the battery in a pocket or purse.
2. Connect the long cable to the speed controller.
3. Turn on the fan.
4. Pick up the Covidisor, let the shroud hang loose, bring down the Covidisor over your head with the shroud remaining outside. Once your head is in the unit, rotate it forward so the inner hat fits comfortably. The front speaking diaphragm should be lower than your chin. If not, rotate the unit forward.
5. With the fan running you should feel the air coming up your neck.
6. Run the elastic band around your neck (and inside the fan cable) and tie it in a snug bowtie. At this point you should feel the air switch to coming in from the front filters and no longer up your neck. It’s important that the shroud be snug around your neck so the air enters the sphere via the front filters and not up along your neck.
7. You can adjust the speed of the fan via the speed controller connected to the batter.

Taking off the Covidisor

1. Loosen the elastic band around the shroud.
2. With both hands, rotate the Covidisor sphere slightly back and then pick up the sphere straight up.
