"Needed to buy spare filters for JSP 1/2 mask, these do exactly as I needed and fit a treat, price is good and customer service at my local store is second to none, they were more than helpful. have been very satisfied with the way they work. in any dusty environment these are an essential work aid."
"Needed some dust and formaldehyde protection as I was starting work making MDF plaques for a craft club. After the usual search for what worked best, ordered these from Screwfix via Click & Collect so I could get started. Good firm fit to the JSP 1/2 mask and have been very satisfied with the way they work. Scroll sawing and sanding MDF produces a lot of fine dust so these are an essential work aid. Also saves me from having to think about actual hours worn rather than checking their continued effectiveness."
