Abstract

The objectives of this study were to develop and determine the effect of anti-microbial mask filter. First, we studied herbs with antimicrobial properties. We found that 6 kinds of herbs showed effectiveness against bacteria, fungi, and virus, and extracted them. The herbs included: Khamin Chan (Curcuma longa L.), Fha Thalai Chon (Andrographis paniculata), Ya Nang (Tiliacora triandra), Mara Khi Nok (Momordica charantia), Phlu Cow (Houttuynia cordata) and Salet Pangphon Tuamia (Clinacanthus nutans). We also observed that 95% ethanolic extract at 5 mg/mL was productive for killing or inhibiting microorganisms. Simultaneously, our investigation of absorbent cloth properties revealed that flannel fabric produced from the polyester fiber possessed the properties of flexibility, smooth surface, softness. The flannel fabric also did not irritate skin. We found that sunlight degraded resistance, and either killed or inhibited microorganisms in the flannel. The flannel also effectively absorbed the herbal extracts. We soaked the flannel with the herbal extracts at 30% relative humidity to reduce face-contamination and skin irritation. The results from the performance test showed that the anti-microbial mask filter effectively provided significant prevention and inhibition against the transmission of microbial aerosols. The flannel could be developed as a mask filter against other harmful microbes.
