"I'm just now getting into resin work and dice-making, and the one thing you absolutely must have is a mask and filter set like this. The goggles included here are important for eye protection from the fumes and from flying debris (sometimes there's little pieces that need to be trimmed off and they can go flying), and these goggles are really comfortable and don't fog up. But the really essential thing here is the respirator mask. You have to have a respirator mask to protect yourself from toxic resin fumes. The mask fits flush to the skin (and is surprisingly comfortable!) and the air you breathe in is fed through the filters on the sides. This pack comes with 8 filters, and it's a good idea to write down when you last changed them so you can cycle them with regularity.
One word of caution with this set: you see those 3 prongs on the "snap-in design" in the product pictures? The plastic on those is very soft and I would not recommend "snapping" the filter box into place. Just visually line the 3 prongs with the corresponding 3 holes, gently lay the filter box flush against the valve (instead of "snapping" it on), and turn to secure it in place. No snap needed, and you don't have to risk breaking one of the prongs.
Overall, this respiratory mask and goggles are great. I'm planning to buy another set for my spouse so that he can work with the resin with me. The mask is comfortable (shockingly to me! I did not expect it to be!), the bit that slips over the head to hold it steady is also comfortable, and the part that secures behind my neck is easy to operate. Please value your safety above all and don't work with resin without protecting your eyes and lungs!"
