Bio Sand Filter (water filter)

Post by Geoffrey » October 15, 2016, 8:53 am

These are simple and effective water filters. There are some details here:

I'll be in Chiang Mai in January and will bring back a bio sand filter from the Rain Tree Foundation for myself. Would anyone like to order one? I can bring more back. The cost of the filter is 1300 baht. I'd like some to help with transportation; I think 600 baht for each filter will be good.
