Introduction: COVID 19 is a global pandemic which has led to crisis in supply of essential goods and services, personal protective equipments including face masks.  Aim: To Compare Adi’s five layered cotton face mask with N 95 mask with regards to cost and efficacy. Material and Methods: After IEC, sample size of 10 was randomly selected. In a closed chamber made up of glass, three plates of blood agar (BA), chocolate agar (ChocA) and MacConkey agar (MCA) were kept and at four different times, first without mask (Group D), second with N95 mask (Group N), third with surgical mask (Group S) and lastly with Adi’s face mask (group A). Participant at first coughed 3 times then sang for 3 minutes and lastly spoke for 2 minutes for each group. Plates were observed for growth after 24 hours. Inclusion criteria: Age 18-40 yrs of either sex, with no co-morbidities. Exclusion criteria: Anyone having cough, cold or fever. Results: In Group A, one pink pin point colony was seen on MCA, in Group N, one pink pin point colony was seen. Conclusion: Adi’s mask is almost equivalent to wearing N-95 mask. It is easy to use, innovative, simple, scientific and cost effective.
