### ⭐⭐⭐⭐⭐ Review
*by 花***暮 on February 27, 2026*

自宅で1年ほど使い、とても良いので実家にも購入しました。 最初の投資が少し高いですが、コスパを考えるととても良いと思います。 最初にこちらを購入する前に、浄水ってそもそも、何をどうやって濾過したいのか？、PFAS？ペットボトルでお水買う？ペットボトルのマイクロプラスチックは？浄水器もプラスチック？ 濾過材の不織布は？等等、考え始めるとキリがなく堂々巡りになりましたが、ペットボトル買うよりエコだし、簡単だし、ゴミでないし。 安全性が見えにくいウォーターサーバーより、基準をクリアしてる水道水を、更にろ過したほうが確実なのでは？ ＆、これならアルカリイオン水作れるし、大量に使えるから、炊飯や全てに使える！ という訳で、こちらに決定。やはり大量に使えるので、口に入れるもの、ペットも含め、惜しみなく全てに使えるのがいいです。 自宅はステンレス管ですが、それでもこちらを通す前と後では、はっきり味の違いがわかりました、そんなに味覚鋭くないんですが、普通に違うなぁと。 そして、2台目を設置した実家は、古い＆多分銅管なのもあり、煮炊きするときなど、いやいや水道水を使ってましたが（置き型浄水器も使ってはやめての繰り返し）、こちらにしたら、かなり美味しくなりました。 炭酸水も買うことなく、こちらの水を使って心置きなく作れますし（ソーダストリームで）、アルカリイオン水も美味しいです。アルカリイオンにしてから、食欲が減る一方だった母の食欲も少し戻ってきました。
