60923 Filterpatronen voor adembeschermingsmasker, stofdicht, organische stoom en chemische cartridges, compatibel met 6200, 6800, 7502, FF402 adembeschermingsmasker (2 stuks)

These filters fit the generic brand mask I have at home, and they definitely kept me from smelling the finish I was spraying, as the smell became VERY obvious when I removed the mask later. I assume that also translates into them filtering out the nasty stuff.

These fit easily on my mask. They come individually sealed. Be ready to take a marker and write your own exp date. Basically they need replaced 6 months after opening. Even if you're not using them, if you've opened the foil bag then they are filtering contaminants in the air. I use these for resin pouring crafts. There is a different color for each kind of respirator type. So be sure you are getting the correct kind for the purpose you'd like to use them.

These are generic copies of genuine NIOSH approved filters, and without any required NIOSH testing or quality control. These are filtering particles well for me according to my mask fit testing machine, but not quite at the P100 level.I have no way to test the multi-gas filtering. There is no such thing as a home testing standard for it. So you just have to trust that they work, and there is no good reason to trust a generic filter that isn't NIOSH approved. Use real NIOSH approved filters and respirators when your life is on the line.These are probably fine for nuisance levels of hazards, within the safe occupational exposure limit.

So these fit and work perfectly in my masks I have for in my 3d printer room so the resin smell doesn't kill me. These seem to be airy enough to let you breath normally all while keeping all the nasties out. Longetivity will be helped by keeping in an airtight bag or container between uses so these should last a good while.

These filters fit my name-brand mask just fine and seem to seal well. They'll work fine for particulate and dust and such when sanding in my workshop. I don't know that I'd trust them with my life 100%. Not like I have a way to test their filtering claims. They do seem to filter most smells out. I stuck my face into the outlet of my BBQ smoker and inhaled no smoke but could still get a whiff of that brisket goodness. Use that info as you will.
