YES, Chiki Diki manufactures high-quality face masks & clothing, with a purpose. All face masks & clothing is made with antimicrobial fabric to help prevent bacteria and other microorganisms from attaching to the fabric surface. For complete antimicrobial protection, it uses silver ions to help control odor, create long lasting freshness & inhibit bacterial growth while being breathable for use all day.

The historical use of silver as an antimicrobial agent is well documented and has been shown to have a very broad spectrum of activity. Silver ions are extremely effective at controlling the growth of both Gram + and Gram – bacteria. With the controlled release of silver ions found only in the SILVADUR™ antimicrobial polymer system, all bacteria and fungi are extremely susceptible to this technology.

Independent, third party microbiological laboratories have confirmed that samples properly treated with the SILVADUR™ antimicrobial technology will easily demonstrate greater than 90% bacterial reduction after 50 home launderings.

Dow recommends using the ASTM E3160-18 and the ASTM E3162-18 test standards for measuring the durable antimicrobial activity of treated textiles. Dow requires that these tests are performed by laboratories certified by the International Antimicrobial Council (IAC) to be trained and proficient at performing these standard methods to industry criteria. Laboratories must provide valid IAC Verification Numbers with each test report that indicate the laboratory and technicians have performed the methods appropriately. ASTM E3160-18 is based off other standard tests such as the AATCC100, ISO20743 and the JIS L1902 and follows the OECD Task Force on Biocides guidelines for measuring the antimicrobial activity of treated articles. Treated samples must demonstrate >99% bacterial reduction following these guidelines.

No, the antimicrobial test method recommended by Dow comes at the recommendation of the International Antimicrobial Council. This method reflects the latest standard specifically designed to measure the antimicrobial activity of ALL antimicrobial treated articles. This recommended method follows the guidelines of the OECD Task Force on Biocides and is intended to more closely reflect conditions that might be experienced by ANY antimicrobial treated textile in use.

IAC Certified laboratories are specifically trained on the details of performing standard industry antimicrobial methods. The exact proficiency of each laboratory is updated and tested on a yearly basis with on-site technical training and blind sample evaluations. Improvements and updates on the latest changes in antimicrobial testing are provided to each IAC Certified laboratory, which ensures that you are getting the proper testing performed on your treated article.

No interference with other typical textile auxiliaries has been seen with the SILVADUR™ non-ionic polymer system.

The ASTM E3160-18 test is the most reliable and effective test method that can be used to measure antimicrobial effectiveness of all current antimicrobial agents on the market.. Other methods that have been used to measure the antimicrobial effectiveness include but are not limited to: AATCC100, JIS L1902, ISO20743, and ASTM E2149. These test methods must be run at IAC Certified test laboratories and must contain an IAC Verified test report to be valid.

Unlike particle based silver technologies that release both ionic silver AND silver laced particles into the surrounding area, SILVADUR™ only releases silver ions at the surface of treated fabric. This means that NO “Zone of Inhibition” (ZOI) will be seen with SILVADUR™ treated samples. Since no ZOI is created, test methods that determine the performance of an antimicrobial based on the size of the ZOI are not appropriate for the SILVADUR™ technology. These methods include AATCC147, ISO20743 (Qualitative Method), and other agar based protocols.

Dow recommends following the latest test practices developed to measure the durability of antimicrobial treated textiles. Using the ASTM E3162-18 test standard, the SILVADUR™ antimicrobial technology has been shown to be effective over the “life of the goods.”
Laboratory testing demonstrated excellent antimicrobial activity after 50 launderings, which exceeds most expectations for the “life” of textile products.

The application instructions for SILVADUR™ technology are very clear for both exhaustion and pad applications. Simply follow these application instructions with the recommended addition levels (based on the weight of the goods) and you should have no problem meeting microbiological performance parameters.

Yes, Dow scientists have developed a method that will allow both the mill and the brand owner to detect the presence of the SILVADUR™ technology directly on the treated goods.

No, SILVADUR™ does not alter the "hand" or moisture management properties of the fabric. Because SILVADUR™ treatment is invisible with respect to touch and sight, DuPont has developed methods that allow mills and brand owners to detect the presence of SILVADUR™ technology on treated goods.

No. The SILVADUR™ antimicrobial system is an all-in-one polymer. The polymer system interacts with itself and with the textile surface to provide its own polymer network on the surface. This polymer system binds the silver directly and only releases the silver ions when needed. This unique polymer system requires NO extra binders and NO excessive heat curing to apply.

Silver particle antimicrobial agents act by providing a large supply of silver doses inside a particle structure. The SILVADUR™ polymer system is NOT released from the surface and due to its “smart polymer system” will only release silver ions AT THE SURFACE OF THE TEXTILE. This means that no silver laden particles are released into the environment. Due to the very low level of silver ions released, discoloration of the treated surface is NOT a factor.

Exchanges only at this time, please contact seller with any issues at:

NOTE : Masks should be washed before use to remove any machine and handling residues.
HAND WASH : Using very hot water and ordinary dish washing soap (not lotion/moisturizing soaps). Heat the water, pour into a bucket with soap and immerse the face mask(s). If heavily soiled, add an oxygen cleaner (for example, xyclean) according to the package instructions. Agitate, soak. Rinse very well in plenty of water. Squeeze well. Let air dry.
MACHINE WASH : Hot water, using laundry soap that DOES NOT contain fabric softeners; a powdered detergent is preferred. If in any doubt, choose a powder detergent. Add an extra rinse cycle as needed. Air dry or machine dry on a warm cycle.
If machine drying, consider using a mesh bag to prevent damage to elastics or ties.
Other sanitizers could be used with soap/detergent, when washing by either hand or machine. These are household bleach, liquid laundry sanitizers (for example, Pine Sol), quaternary ammonium salts, such as found in many over-the-counter cleaners (check the label). Follow the label directions.
