more cleaning water capacity with one cleaning kit
two cleaning kits we are getting for free.
I have tried purifying rain water which I have collected by keeping a dish outside while raining. Completely filled with mud and particles. To my surprise , the output is clear water with good taste.
Purification is a little bit slower but I think it is good enough for the money.
