## Customer Reviews

### ⭐⭐⭐⭐⭐ しっかりとした加湿力
*by A***ー on February 6, 2026*

大容量なので頻繁に給水しなくて済み、夜も連続で使えて便利です。 上から給水できるデザインも使いやすく、お手入れも簡単でした。 この価格でこの性能ならコスパはかなり高いと思います。

### ⭐⭐⭐⭐ ぴちゃぴちゃ音
*by ま***。 on January 9, 2026*

加湿はされます！！給水口も広くお手入れしやすそうです。加湿器を稼働している際、ぴちゃぴちゃお水の音がします！ 寝ている時、気にして寝れない人もいそうです（ ; ; ）

### ⭐⭐⭐⭐⭐ 静か
*by 村***斗 on January 30, 2026*

超音波式の加湿器を使ってみたけど、まず音がめちゃ静かで寝るとき全然気にならんのが最高。デザインもシンプルで部屋になじむし、水入れるのも楽。加湿力もしっかりあって、朝起きたとき喉の乾燥が明らかに減った。コスパ的にもかなり満足してる。 水タンクが少し小さめで、乾燥が強い日は1日に何回か水を足す必要があるのが地味に手間。
