GVS Elipse Filters P3 | Dust Mask Filters | Screwfix.com
Dec 16, 2020·Rated 5 out of 5 by LeAtelier from Does the job. These filters are easy to change. Fiddly first time I tried but now super easy, pop the old ones out and pop the new ones in. Job done! As for the efficacy of the filtration,I would say that providing the half mask is fitted to the face properly they work brilliantly for hours.
