Review on GVS SPR551 Elipse Integra Nuisance by Marc Gallner

Size S/M fits my face well and size M/L fits my husband. To determine the fit, I pulled the mask over my face, slightly tightening the straps, and resting my palms on the filter mesh. When I couldn't breathe and covered the filter with my hands, I realized it was the right fit. These respirators MUST be worn tightly enough; If this is not the case, polluted air will enter through the sides or the chin area. I couldn't wear my goggles with goggles so if you wear goggles you can get a GVS respirator without goggles. I did a little research and found that GVS is based in Italy. It's reassuring that their respirators are made in Italy, not China. I know there are many fake masks and respirators out there. Fortunately, the CDC has a list of FDA-approved respirators, broken down by brand. GVS is *IS* on the list, so this mask is the real deal. I wasn't sure how long the filter was safe to use, so I emailed the company. Their helpful customer service rep quickly emailed this response, which included the answer to my question and information on how to properly clean and reuse the filters: =================== == =========================================== Filter should change once a month or more often if you experience resistance to breathing. Records of these filter changes should be kept. Filter installation instructions are included with replacement filters." MASKS AND FILTERS TOGETHER: Use the autoclave machine. Autoclave the mask according to your autoclave manufacturer's instructions. An example autoclave cycle would be: 70 minutes at 250 degrees Fahrenheit.
