Hello ..
I am drinking purified water by purification filter . i take one can for month it is 25 liter ( only i use night time ). That can cap is very tight ,it is keep in room not in sunlight . I have a doubt that water is good to use whole month .
Please clarify .......
Thank you
Venu
Very difficult to say for sure. Depends on the starting quality of the water and the efficiency of the filter. Also the ambient temperature will have some effect even if the screw cap is tight. In summary I would tend to err on the side of caution and replace it every 2 weeks.
