Homemade UV + UF (4 stage) water purifier for tap water- very effective & cheap



This is video tutorial to make very effective & cheap 4 stage water purification system to purify municipal water (tap water). You can also add pre- filter as 5th stage, this will increase life of other filters. Pre- filter can be easily clean.
You can find all the material at local spare part shop. Or you can purchase it online using links at the end.
I recommend to purchase the material from local store because prices are little high online.
Materials:-
1x Sediment filter (standard 12 inch filter)
1x Carbon filter (standard 12 inch filter)
1x UF Membrane
1x UV barrel / bowl 8”
1x UV lamp 11 watt (Philips make)
1x UV Choke / adapter 220v AC
1x Teflon tape
6x Elbow (1 side push fit & 1 side threaded)

10 feet RO filter Pipe
Double sided tape
2-3” piece of ½” water tube (pipe)
23 x 15 cm piece of plywood

Note : replace the filters ( sediment, carbon & UF) every 12-18 months based on water uses. Do not drink 1st 10 liters of water during 1st use as it may contain residual dirt etc.
