[Expired]Bluevua Countertop Reverse Osmosis Water Filter System

: I've been using this little one for over half a year. It looks great and doesn't take up much space, but it's only enough for me to drink alone since I work from home and can drink 小的我用了大半年了，颜值高不占地方，但是只够我一个人喝，我wfh且能喝

: 1.7L seems a bit small. Are there any larger options available? 1.7L感觉容量有点小啊，有没有大一点的啊？

: Currently, there's just one issue: when I pour the water it produces into a purified water jug bought from the supermarket, after about a month, the bottom of the supermarket's purified water jug turns yellow. I don't know why, and is there after-sales service? Theoretically, this shouldn't happen; supermarket water doesn't change color at the bottom even after being stored for a month. Can after-sales service explain the reason? What kind of container should I use to store the extra purified water I purify? Thank you. 目前就一个问题，把它出来的水倒进超市买来的纯净水桶里，时间一个月左右，超市的纯净水桶底上就会发黄，我不知道什么原因、有售后吗？理论上不应该啊，超市水存放一个月也不会底部变色。有售后能说下原因吗？我多净化出来存起来的一桶水该放什么容器？谢谢
