No I don't think so I'd use any fine mesh I could find 250 micron is still very fine, the fly screen from a tent, a midge net, a pair of tights.Does it need to be exactly 175 micron or nah?
If I were using tights I'd strip the aluminium foil from some ducting to act as a support and keep them open to maintain a high flow.
