I made water wall from a fogger for agriculture/gardening.
It lowers air temperature, cleanses air from dust.
Great for hot weather when there is no air conditioning.
Only outside use!
Step 1: What You Need
connection to the tap (pic.1,2)- compatible with your water pipe (my is 4 mm, internal dimension, pic. 5)
tee (pic. 3)
water fogger (pic.4) important with low water consumption - nice mist, low water use
zip (pic. 6)
scisors, knife, optional some tape
Step 2: Bulit
Hang the water pipe about 2 m above the ground- under the balcony, pergola, sun umbrella etc.
My option is a link/tape with zip.
Using tees install a fogger at intervals of about 1 meter
Connect to a tap with water and do not forget to plug/cork one end of water pipe.
*Water fog is so delicate that you can not see it in the pictures, but it is.
