Bros, i got quite a few extra HEPA, don't think i need that much. You wanna buy over? It's about 95% efficient @ 0.3 microns when i put it into my Sharp A28.
6pcs for the lot, 300mm x 300mm x 25. But without the cardboard edge, so easier to DIY if cutting.
Sell just $50 for the 6pcs as a lot. I eat the 4PX SZ->SIN shipping, by itself its a 3kg package liao.
This one can be cut and used in Sharp A28, Novita NAP501 (the HEPA portion is only 17mm), even can use in the Samsung AX40 (310 x 280mm) if desperate, etc.
If you need some pre-filter 100 microns foam, let me know...i can throw in
FOC.
Let me know if anyone is interested.
Edit...ok...i can throw in 2pcs of velcro to attach to the fan if you want.
