Frequently Asked Questions

Q. Hello! I wanted to enquire about your Multi-functional HEPA-grade filter media Do you sell these by roll? or by kg? What is your MOQ? We're a HK based company that specializes in bespoke shirts. Our factory is in HK. Due to current situation, we are trying to make some facemasks with a replaceable filter. First priority is to make for our staff and their families, and also for donations to the needy and elderly in HK. Of course, I've been following FB of Dr KKwong, which is how I found you guys. I'd be more than happy to give him credit for facemask design. However his press conference is tomorrow, but I thought I'd contact you first to see if we can source the filters from you. Thank you and All the best! Justin Chang Ascot Chang www.ascotchang.com
