SONAKI フィルターカートリッジ5本（SONAKI シャワーヘッド専用フィルターカートリッジ） …

While this was a refill order, I originally purchased the "starter kit" with shower head almost one year ago. Prior to purchasing this product, I started noticing my skin itching after showers. As the itching become worse and more prolonged, I tried different moisturizers, soaps, and even supplements desperate to find relief. While I was at a natural food store, looking for something to try, I mentioned the itching to the homeopathic practitioner, and she told me about a vitamin C filter that would filter out the chemicals in the water that may have been causing a reaction. I found the Sonaki website and ordered the shower head and filter. Within one week the itching just stopped. I didn't replace the filters once they ran, and just went without them for about three months. Over the last few weeks, I started noticing the extreme skin itching and irritation after every shower. I ordered the refills, and after my third shower, the itching has completely stopped. In addition, my hair is less frizzy and my skin is softer. I'll never run out again. This product has been a lifesaver!

As expected

Been using this product for a few years now......there is no smell of chlorine in my water now......and after doing research I think this product is good....I drink this water also.....because where I live they use heavy treatments in our water....and the smell of chlorine is horrible when you turn on the tap.....I recommend this product for people who are unable to put in their own water filter system.....

refills! what's to say?

Great product but most people quickly discover that these cartridges go fairly quickly and it gets annoying, getting them at $5 or more each.I have seen all sorts of methods to reuse these but manufacturer is not as bad as many portray them to be, these are reusable, you just need to know how to get them open.Top portion is glued in by small amount of glue and depending on the batch you get glue maybe stronger or weaker. If you apply force properly you will be able to pop the top open and then they become very easy to refill and reuse.Tightly grab the filter and press upwards on the top part only above the black O-ring, you may need to apply decent amount of pressure and rotate it trying different spots but eventually glue will give and top section will pop off. If its not giving, put it in some very hot water for a while and try it that way.Once the top comes off you will need to tap it upside down to get seal and cap out, make sure you keep all parts. Then wash it and dry all parts and grab some food grate powered vitamin C. this stuff is very fine, so after you fill it tap it to pack it better and once full add bit of water to the top, to prevent power from moving and pack it in(important to pack it in or it will dissolve much faster) below the line where cap will sit. Then put the cap and top back, don't forget cloth looking filter, installed O-ring will seal it and keep everything secure, no need to add glue, filter gets pushed from the top and bottom when in use and will stay together.Photos below and you are welcome.
