Making the Mask • Sand around the edge touching face with two hundred plus sandpaper. • Spray mask inside and out with two coats of clear sealer and let dry completely. • Fasten elastic cord to the attachments and adjust to desired tension. • Elastic chord, string, straps, or any variation can be used as ties. Placing Filter / Filters and design benefits • Existing clinical masks (material) can be used as a filter by cutting them into two point five in squares, can get six filters from one mask. • Replacement filters can also be ordered from High Tech Filters Shane Rekdal 800-785-6985 or email shane@flowmarkhightech.com • Place filter material on the inside of the mask and fasten by pushing holding ring and filter together into space. • Cotton T-shirt material can be used as filtering material. • Between filter box and mask Louvers a “Pre-Filter” of a coarser material such as polyester non-woven material can be inserted. Zero point five mm X forty-six mm x forty-six mm space exists between filter box and outer Louvers. • An outer “hair net style” of filtering material could be draped over and around the EXTERIOR FILTER NOSE retained by elastic wrap to provide additional “Pre-filtering” action and protection of the mask if desired. • By air flow re-direction and blocking of misting contaminates is also a desired action. • The Flat EXTERIOR FILTER NOSE provides a convenient means to lay the mask down and still protect the inner filters. • Any of the above “Pre-filtering” methods should extend the life of the INNER PRIMARY FILTER material. • IMPORTANT: To remove the pressed in filter, INSERT any blunt object (thickness < 2.0mm / 0.100”) between either the filter nose body and either the UPPER or LOWER louver to press out the filter box. Aseptic Technique • These masks are reusable, but each person should have their own. • Masks can be cleaned and disinfected by soap and water as well as disinfectant agents. • Practice good hygiene by washing hands before and after changing filters and removing mask. • Clean mask often, change filter often.
