Gonna build DIY flowhood.
Looking for a filter.
I guess ebay and china/Hong kong seller with free international shipment might be my best option.
I ended up with ton of vacumecleaner filters that might fit some basic hepa but not h16.
using ulpa in search gives 0 result.
alibaba offers some but they seem to be for business/ retail - I did not find seller that would ship only few units with free international shipment.
Has someone found nice one and could share a link? Thank you for reading and hopefully link too :)
