What Korean customers say
13 excerpts about installation, fit, travel and refills, translated from Korean.
★★★★★
Most filters like this have only one filter, but this one filters in both the head and the body. Installation is just twist-on, so it's really easy. The design is simple and clean, too.
★★★★★
10 days in Spain and Portugal, a different place every night, and it fitted every shower. From day 6 I could see the filter changing colour as it worked. … Wishing this Korean company every success.
★★★★★
Used it on a trip to Southeast Asia, in 3 different hotels. Easy to install and it fitted every time. … I bought both versions: the premium one for travel and the basic one at home.
★★★★★
I used it while travelling in Europe, where the water is very hard. Seeing the filter change colour put my mind at ease. The head is small and light, so it's easy to pack.
★★★★★
I already use the Water Healer travel filter and bought refills to keep in stock. … If you're heading somewhere with poor water quality, I'd recommend packing a spare.
★★★★★
I ran out of refill filters again, so I reordered. Changing the filter is simple … I'll keep buying refills.
★★★★★
Used it for a week in Thailand, moving between places to stay. One filter lasted the whole trip, so there was less to pack, and it was simple.
★★★★★
It looks clean and the water flows well. … Assembly was very easy and it fitted our faucet.
★★★★★
The head and the handle come packed separately, and there's hardly any installation: take off the old head and twist this one on. Really easy. It would make a good housewarming gift, too.
★★★★★
The filter fitted European showers well, and attaching it was not difficult. If you are planning a trip to Europe, I recommend it.
★★★★★
2 weeks into a trip in Europe and I'm very happy with it. It fits European showers really well.
★★★★★
I like that I can check the condition of the filter with my own eyes.
★★★★★
Easier to carry than taking a whole shower head, and easy to fit in the hotel.
