The filter pocket mask is made from two ply 100% cotton. Each mask has a built in flexible nose piece to create a more custom fitted mask and minimize eyeglass fog. The mask is a pleated style to expand to your face size and a filter pocket at the top of the mask.
Each mask includes a 3.5" X 7" FILTI filter. FILTI is constructed using a patent-pending Nanofiber technology. It is an 80gsm, three layer design consisting of a polyester spun lace outer, tight network of FDA certified polyurethane nanofiber, and polypropylene spunbound scrim to support the nanofibre.
Manufacturing specs are targeted at 95% efficient at 0.3 microns. Please review the specifications at HTTPS://FILTI.com.
Note: the outside of the filter has a loftier texture and should face away from your face.
Choice of adjustable elastic ear loops or elastic cord with cord lock.
Elastic Ear Loops: The elastic is adjustable by making a personal fit and then putting the knot in the channel of the side of the mask.This is a handy closure system for elders, people with dexterity challenges and going to the hair salon.
Elastic Cord and Cord lock: the system offers the best fit as the circular elastic cinches up the mask to your face creating a custom fit.

Care for the exterior of the mask: wash and dry flat or line dry. Iron but note, the nose piece is made of plastic and may melt. No bleach. Do not microwave as nose piece has metal.
Care for FILTI Filter: The filter should be replaced after each use. If the filter will be reused then CDC sanitization guidelines should be followed if the filter is not disposed of. NIOSH found that as of April 2020, ultraviolet germicidal irradiation, vaporous hydrogen peroxide, and moist heat have shown the most promise as potential methods to decontaminate FFRs. quote CDC.gov.
