1 layer mesh why no good leh? mind explain?

Filteration effectiveness of mesh wire filters are the worst of the lots. They allow the most air to go in thus increase in performance BUT they also allow LOTS of micro particles to pass thru as well. I've use a double layer mesh micro compressor on my ex-wira. When opened up the compressor, can find black powder (dirt) INSIDE the compressor bypass the mesh wire. The mesh wire do filter large number of the powder but a significant portion still makes it thru.
So if you DO value cleanliness of your engine, I would suggest forgoing mesh filters. Its one of the first filters used ages ago before development of paper filters that totally replace them due to much superior filteration effectiveness.

anyone have tried 3m tinted? how much for full persona?
Effectiveness of 3M high end tint is similar to VKool Elite. However 3M has a major weakness as its IRR is even higher than Elite (high IRR does NOT mean better heat rejection although its does counts towards total solar rejection). This means SMART TAG users, GPS and remote has high difficult to get thru them. VKool Elite used to have same issue but seems to have significantly improve of the signal getting thru. Now VKool does get thru Smart Tag lane easily but HAVE to drive thru slowly as detection rate is slower than other tint or non-tint. 3M has lots of issue detecting signal thus some have to cut a hole for signal to get thru just like what VKool did a while ago b4 the improvement.
Other than that 3M is up there with VKool in TSER effectiveness. Price also up there almost same with VKool. I'm currently using VKool Elite for all my rides tho now a bit itchy to put in security tint as instead. But figures TSER still more useful as I spend lots of time in car under hot sun.
