Karihana Seisakusho sells a disaster water purifier "mizu-Q500" that can change water from baths and ponds into drinking water that meets the water quality standards of the Waterworks Law. It is characterized by the fact that it does not require electricity, is easy to handle, and has high processing capacity.

"Mizu-Q500" uses a manual pump for water purification treatment. Since it does not use electricity, drinking water can be obtained even when there is a power outage due to a disaster or the like.


Silver-impregnated activity and 0.04μ hollow fiber are used for the filter medium, and no chemicals are used for the filtration work. All you have to do to make drinking water is to put the suction hose into the water source and turn the handle, so even children in the lower grades of elementary school can handle it.


The hollow fiber filter can remove Escherichia coli and bacteria. It has a processing capacity of about 3 liters in 1 minute, so a 500cc PET bottle can be filled in about 10 seconds.

It measures 380 mm wide x 270 mm deep x 700 mm high and weighs 3.5 kg. The price is 94,800 yen. One exchange filter that can purify about 3,000 liters of water costs 9,800 yen (all prices do not include consumption tax).
