- Yaocom 4 Pack Copper Woven Mesh, 11.81 x 8.27 in Air Vent Filter Screen | 99.9% Pure Copper Wire Mesh Sheet, for Air Vent Window Hole Blocking, Grounding Dense Filter, Durable Metal for Home Workshop

Nice product. Screens consistent/regular and nice quality, and not too flexible (good stiffness).

We bought these to keep squirrels and mice out of our ac/ heat pump box. Last winter a rodent chewed through the wires at the connection resulting in a $2800 repair! We were told this screen would prevent a repeat by keeping the rodents out of our unit. Let’s hope it works when winter arrives.

I cut two by two inches pieces to put in my pool skimmer. It actually works great because it's copper.It keeps algae out of my pool.

Exactly as advertised, worked great as a microphone faraday shield!!

Haven’t been able to use it yet

Beatiful perfect clean mesh sheets, just as described, cuts easily with a scissors.

These are excellent quality 100% copper mesh sheets. they are perfectly cut, arrived flat and without damage. While the product description states they can be used to keep small animals out of vents, I use them for artistic purposes. The mesh is easy to cut with scissors, and it can be folded or shaped easily with your fingers. It’s perfect for my uses in metal work, enameling, and fused glass. Very pleased, and would purchase from this seller again without a thought.

These are as advertised, and the screen is about that you would get with insect screening, so good for paper making or screening a downspout. Came wrapped in bubble wrap in a paper box. Undamaged except for the corners. The edges are somewhat sharp so be careful when handling.
