Pairs well with
Replacement 3M pre-filters, two per pack, for a full-face respirator used while vaporizing oxalic acid.
The pre-filter is the layer you are meant to use up. It catches particulate before it reaches the cartridge underneath, so the cartridge lasts longer and costs you less over a season. Swap the pre-filter when it looks loaded or when breathing through the mask starts to take noticeably more effort — whichever comes first.
Two per pack, so there is a spare on the shelf when the first one is done. Ships from our shop in Baltimore.
Oxalic acid vapor is an irritant. Always follow the respirator manufacturer's fit and replacement instructions, and treat with the hive downwind of where you are standing.
