Review: This kit worked great for my Lancool 207! - I recently built a new PC for my son after his mini PC failed suddenly. I wanted to go with a full sized ATX build, as I usually make for myself, and picked a Lian Li Lancool 207 case. After building the system in the case, I realized that the air intake meshes were great for airflow but also great at letting dust in. I have previously made DIY magnetic filters for my Phanteks P500A case when the same situation faced me a few years back, so I looked at my options and selected this one largely on the basis of good price with a good review average. I am pleased to say it was a great choice. I had no trouble making intake filters for all of the meshes on this case. There's one particularly unprotected air intake which has very large hexagonal gaps the same size used for the rear air outflow, and I think covering that one is actually pretty important if you don't want a lot of dust coming in where SATA drives are, blowing right up into your video card through the horizontally mounted fans (you know what hates dust? horizontally mounted fans, really hard on their bearings over time as lubrication distribution is harder for them than vertically mounted fans). Please view the attached photos so you can see what I mean when I said there's plenty of materials to make all the filters you need for a case with modern airflow. Speaking of, they do reduce airflow somewhat compared to unimpeded bigger gaps, but if you're in a modern case you should still have very good airflow. I've used something exactly like this for years on my P500A case with a 12900K and it has never caused temperature issues, despite covering the entire front intake mesh so I reckon it's going to be a winner for keeping the interior clear of dust (which tends to help keep air moving nicely, you know?)
Review: perfect for PC filtering - This was exactly what i was looking for screen material is made of quality plastic, but easy to cut with scissor or box knife. Does not seem to hamper the airflow hardly at all (nothing noticeable). Cutting to fit is super easy and I could easily do 2-3 PC's with the amount of material you get. Mark with silver sharpie or colored pencil before cutting and clean edges with IPA to ensure proper adhesion of magnet strip.

## Features

## Questions & Answers

**Q: i know the mesh is .45mm but what is the magnetic stip thickness?**
A: 1/4"

**Q: can this mesh be doubled up in certain places / joints that will meet up since I need it to be a bit bigger? Any tips on how to do this effectively?**
A: Hot glue maybe.

**Q: Does this work in an aluminium case?**
A: The only problem with this is that Aluminum is a non magnetic type of metal. You would need some way to attach the screen material to the case. The screen material would work as a filter you just need a way to attach it. I could suggest maybe checking a hardware or art supply stores for some type of attachment with a channel made to slide
a flat  object into for display on a wall or glass.

**Q: Is there any way to attach these to an acrylic side panel? Could the strips be put inside to attach to those outside?**
A: if you can drill very small holes and find 4 screws and nuts to attach
could always glue to inside of acrylic

### ⭐⭐⭐⭐⭐ Absolutely perfect!!👍👍👍
*by J***Y on February 25, 2023*

This is the stuff here, excellent thickness, plenty of material to fully filter an entire larger size gaming tower. It comes packaged in a large plastic sandwiched between two pieces of cardboard that keep it from getting beat up, folded, or otherwise damaged. No mesh will ever fully dust proof your computer, this will only increase the amount of time between routine cleanings that are necessary to keep your system running at peak performance. The holes are on this are such that they should be able to keep out pet hair, your hair, and larger material. I don't notice any restriction in air volume and temps seem relatively stable in very close to pre mesh temps, I'm seeing a .5 to 1 degree c increase which is negligible. This stuff is easy to work with, cut, and attach the magnets. Magnetic hold is pretty decent as well. After reading reviews on several others like this I noticed a common thing in that generally it's shipped in a roll which gets damaged in shipping. This was one of the few that is shipped correctly and the price is lower than others that are shipped rolled. Save yourself a few bucks and the aggravation of receiving damaged mesh and go with this one.
