New to China – or newly arrived in your city? You may have already noticed (or heard before coming) that tap water is generally not recommended for drinking. You might also find that using tap water for showering, laundry, and daily household use feels different from what you’re used to. That’s why water treatment and purification are often essential.

刚到国内或新城市？你可能已经感觉到、甚至来之前就听说过自来水不适合饮用。在洗澡和洗衣方面，你也有可能会感受到明显的差异。因此，进行有效的水质净化是很有必要的。

Online Search VS User Referral

网上搜索or用户推荐

You may have done research before choosing a filtering system – using AI tools (DeepSeek, ChatGPT), research engines, local forums, WeChat groups, or by asking friends for recommendations.

选择之前，你肯定也会做对应的调查，或是通过ai软件（DeepSeek, ChatGPT）、搜索引擎等来获得这个城市不同净水产品跟服务商的信息，或是询问微信群或者身边的朋友了解他们使用产品的推荐。

In practice, AI suggestions often lean towards domestic brands and may not reflect the most established service providers in your specific city. Search engine results can also be heavily influenced by advertising. Overall, referrals from real users around you tend to be far more useful and realistic.

目前，ai软件所推荐的结果大多是国内品牌，甚至不一定是这个城市的主要服务商；而搜索引擎展现的结果很多也偏广告导向。综合来看，身边用户的推荐会更具有实际意义。

One client in Beijing from an automotive company shared her story with us. The brands she found before knowing us are mainly those local brands which are not easy to understand or find for the services. Through a colleague’s recommendation, she finally used Greenwave services and is very happy with what we do.

我们一位在北京某汽车业的客户分享过她的类似经历，在认识我们之前她找到的都是存在操作和服务沟通问题的滤水品牌。直到通过一位同事的介绍找到我们，她才从Greenwave得到了满意和愉快的体验。

Communication in Your Language

VS Using Translation Tools

We know you are looking for a solution that truly fits your needs and your home. Would you rather rely on translation apps to communicate with suppliers, or work directly with an English-speaking water specialist? The difference can be significant. Communication matters not only during product selection, but also during installation, after-sales service, and day-to-day use. Having a professional consultant and service team who can communicate clearly in your language can help you understand the differences between brands and models, choose the right setup, and avoid many preventable issues later.

您肯定想选择适合您的需求以及住处的产品，您是通过翻译软件与供应商沟通还是直接与有净水专业的英文顾问交流？这个差别很大。此外，在安装产品、售后服务以及之后的产品使用中都会碰到沟通的问题，会您语言的专业顾问以及服务团队会很重要。那不仅会帮助您了解品牌跟产品的区别，还会真正帮助您选择适合的产品，避免产品使用中的很多问题！

Price Only VS Full-Service Scope

价格至上VS兼顾全套服务

Comparing price alone can be misleading – sometimes a “cheap” option becomes expensive over time. You may pay less upfront but then face limited-service support or additional charges every time you need help. Over a year, the total cost can end up much higher than expected.

Before you decide, make sure you understand what is included in the price, such as:

1. On-site inspection and installation support (including custom fittings if needed)

2. Regular filter replacement

3. Timely on-site service when issues arise

4. Relocation support if you move (equipment removal and reinstallation)

单纯看产品的价格往往有欺骗性，因为那可能是一个陷阱。你先是花了很少的钱去买，但是之后要么缺少真正的服务，要么每一次服务都会需要您支付额外的费用，因而一年下来支出的成本会远远多于开始的费用。你需要了解价格包含的服务有哪一些，是不是有必要的上门查看与安装配合（包括定制配件）、定期的滤芯更换、及时的上门服务以及移机支持等。

Note on filter replacement frequency:

Some companies claim filters only need to be replaced once per year, while Greenwave has observed that certain systems may require replacement as frequently as monthly depending on usage and water conditions. For most households, Greenwave generally recommends replacing filters every 3–6 months to maintain water quality without unnecessary cost increases.

备注：部分公司的产品要求一年换一次滤芯，但Greenwave了解到实际有些产品需要一个月换一次。品质来源的滤芯品质差异不大，但是多久更换用户需要评估，Greenwave建议用户3~6个月换一次滤芯。这样可以最大程度的保证水质、又不增加成本。

Self Employment Service Team

VS 3rd Party Team

Many suppliers sell products online (even those big names you might know) but rely on outsourced third-party contractors for installation and service. The risk is that some installers may not be professional – they could install a toilet in the morning, and then come to install the filter in the afternoon. This can lead to water leaking risks. As long as no issue shows out that day, they may consider the job “done” while you might bear the consequences if that happens later. In some cases, improper connections or non-standard installation practices can create safety or water-quality issues.

很多品牌是网上销售产品（虽然可能是你知道的品牌），通过第三方外包团队来服务。第三方的人员很多不专业，上一家可能还安装着马桶，后面就来安装净水器。他们不会注意安装之后的隐患，只要当天不漏水，跟他们就没有关系，但是后面的漏水情况用户自己承担。此外，是否安装正确也需要打一个问号，部分安装人员甚至可能会出现将废水接到直饮水上的情况。

Whether or not you choose Greenwave, we strongly recommend you to select a professional company with its own service team. They will be careful for the installation quality and long-term performance – because they remain responsible after the installation done. Through some online-only sellers, if something goes wrong later, it can be difficult to find support.

无论您是不是选择Greenwave，都希望您找专业的、有自己服务团队的公司。那样他们会为你的安装跟设备使用负责，不会轻易让风险存在，因为那样他们会承担责任。而网上的销售，如果出现问题，他们可能会消失，你很难找到他们。

Water filters are not something you should simply buy. Do care if the supplier is professional, experienced, real and endurable. In some cases, the “brand” you see may not even be a stable and long-term company. Over the past 15 years, we have seen repeated situations where sellers used a well-known name to market products, operated for 1–3 years, and then disappeared – leaving customers without any service or replacement support.

净水是一个专业度要求很高的领域，不光光只是买一个产品。您看到的一些产品不一定是真正深耕于业内的品牌，有可能只是套壳款并随时有可能消失。过去的15年里发生过多次这样的情况：有人用大品牌做自己的品牌，经营1~3年之后就消失，而他们当时的用户很难在需要时找到任何售后服务。
