Will an American handheld shower filter work in Japan?

Cornelius Thornborrow: the water in japan is clean, so you won´t need a shower filter.

Eliseo Luma: No, not at all. different size of diameter. American one can't engaged with Japanese one due to meric and uncial (cm / inch)

Hilton Paiva: The US filters are too big for Japanese shower heads. If you have a free filter that you can cut to size maybe, but there is no place for a filter in the Japanese heads. So you will be compromising water pressure. Why don't you bring a hand held head from the states with an international faucet adapter. Then you will be able to use the US filters with the US head. One thing though, the US heads are much bigger so again, water pressure will be compromised.Good luck....Show more

Jesse Pirieda: No. They are different in size and shape. Hardly anyone uses his/her own shower filter. For the normal faucet, they sell many kinds of water purifier and some of them are very good. You do not have to bring yours anyway.
