[4 Pack] 400x300mm DIY PC Case Dust Filter, 1.2mm Hole, PVC Dustproof Mesh Filter Cover with Magnetic Strip for Computer PC Case

Works great. I suggest buying extra sheets just in case you do it wrong.

Bought this mesh for my legion go, it gets the job done and prevents dust from getting through the vents of my 3d printed stand.

This most certainly will filter out big particles from the air but unsure of fine dust particles, the jury is out on that as I have just received it.

I never thought I’d say that my new favorite PC mod would be dust filters. I raved about these all day - no joke. If care is used to cut in a straight line, these filters look like professionally-made custom pieces. The appearance is worthy of being fitted even to the outside of the PC case, being made of a stiff-yet-thin matte-black PVC material. The optional magnetic strips that are included are easily cut to fit any shape filter, and the adhesive is good and strong. The adhesive side of the magnetic strip is designed to be applied to the filter itself, so that the magnetic side may attach to a metallic surface. One way I installed these filters is fitting them between the case and the intake fans, leaving off the magnets and punching holes to accommodate the fan screws. The clean and professional look is very pleasing to the eye. The air flow is not severely restricted, but my filters are already performing great - catching dust and small particles of junk that would otherwise be circulated through my PC case. For perspective, one sheet is about as tall as a normal PC case, and twice as wide. And you get FOUR whole sheets, and SIXTEEN magnetic strips. It’s more than enough material for one PC, and if one gets creative, filters can be made for box fans or A/C vent registers in the floor or wall to keep dust from flying around one’s home. An aerator can be made for sink faucets or shower heads. A barrier can be made for a hamster or reptile cage. I imagine it can also be used for pattern sewing and needlework. The creative uses for this product beyond the intended ways are numerous. I can certainly attest to the awesome value and potential of this bundle, and I can’t recommend it enough. There’s a good chance some custom-made and visually-pleasing dust filters will be your new favorite PC modification too!

Best PC protector of dust

Exactly what I needed to make sure cat hair doesn't get into the computer. Works well, easy to cut and install

Perfect! Easy to use, works great!! I have plenty to share with friends.

I expected a soft like cloth almost but is more stiff and hard. Can crease and break. Seeing multiple pieces I was thinking it was multiple small pieces to make the one listed big piece but no, all of them are as described. Like the described size. It will scratch each other if another of the pieces edge hits another. About the static reviews the material has yet to produce a charge to shock me. I feel it sticking to my hair tho when putting above my head. For the users saying it broke they pc or whatever thats user error bro come on. Just walking in socks you could shock your pc. You gotta use the right precautions.. Grounding techniques by touching a metal item or something. Dont let it scare you. Maybe those other ones that shocked was a different material but this one havnt had a problem with that by far. Who put this near a motherboard anyways.. supposed to be for case protection particularly the fans’ part when the fans go. It does stop dust but pretty fast it can build up on the netting that may be normal tho. Id rather have it on there than in my item. I dont get some reviews saying it doesnt block dust. It does. If the holes get any smaller youd suffocate the thing lol. I wasnt expecting it to catch all the dust anyways, just most. Performs fantastic for that. Storing the excess thats not needed is a but tidieous imo tho, huge sheets I gotta just like toss in a drawer tho but with the cardboard so they dont get messed up. Is not a pokemon card bro is a netting for case protection. Yugi nope.
