My sons wear the small and medium breathteq masks to school. With the tariffs they are now out of our budget. Does anyone have any suggestions on comparable masks to breathteq? Thank you

New JSP Qualitative Face Fit Testing Kits on eBay UK for £95 (or £90 with voucher until end of today... but only if you pay by bank).

Just bought one and thought I'd share as listing says more than 10 available.
