A randomised controlled pilot study to compare filtration factor of a novel non-fit-tested high-efficiency particulate air (HEPA) filtering facemask with a fit-tested N95 mask	2010-03-31		.txt	text/plain	2435	133	58	authors: Au, S.S.W.; Gomersall, C.D.; Leung, P.; Li, P.T.Y. title: A randomised controlled pilot study to compare filtration factor of a novel non-fit-tested high-efficiency particulate air (HEPA) filtering facemask with a fit-tested N95 mask We carried out a randomised controlled cross-over study to compare the efficacy of such a mask (Totobobo, Dream Lab One Pte Ltd, Singapore) with fit-tested N95 masks (1860 or 1860s or 1862; 3M, St Paul, MN, USA) in 22 healthy volunteers. In view of the potential benefits of this new mask, we carried out a controlled cross-over pilot study to compare the in-vivo filtration capacity of trimmed but non-fittested Totobobo masks with a fit-tested N95 mask (1860 or 1860s or 1862; 3 M, St Paul, MN, USA). This was a prospective unblinded study of healthy Chinese volunteers using two different protective devices: a Totobobo mask (Dream Lab One Pte. Ltd, Singapore) and a fitted N95 filtering facepiece respirator (1860 or 1860s or 1862, 3M, St Paul, MN, USA).	./cache/cord-279436-kftdqzg0.txt	./txt/cord-279436-kftdqzg0.txt
