For most customers, when they choose a water filter, they are not simply buying a machine. They are choosing a long-term service partner who will support their home, office, or institution for years. In our eyes, what users truly care about is specialization, genuine one-stop capabilities (water + air), professional in-house installation, reliable ongoing service, and the ability to save time and reduce complexity. English communication, reputation, and long-term stability matter even more for international families and organizations.

对大部分用户来说，在选择净水设备时，他们并不仅仅是在“买一个机器”，而是在选择一个未来多年会持续服务的服务商。在我们看来，用户在选择之前真正关注的是服务商的专业度（是不是真正做净水，还是只要销售）、便利性（是否能覆盖多种需求，省事省心）、安全性（是否有安装团队且经验丰富）、持续性（能否持续提供售后）等等。对于外籍家庭和国际机构来说，英文沟通、品牌口碑与长期稳定更是重要的指标。

This article compares Greenwave, 3M, Aquasana and Aquars, helping users understand which brand best matches their real-life needs. We have tried to be as factual as possible, but we will check and do sth per the notice if some info looks opinionated

本文将对比 Greenwave、3M、Aquasana与阿酷尔，帮助不同类型的用户找到最契合实际需求的选择。我们尽可能分享了公正的信息，如有反馈的不足之处，我们会深入研究并做相关工作。

Product Line & Technical Positioning

产品线与技术定位

Greenwave focuses specifically on drinking water and air-quality solutions, offering RO systems, integrated drinking stations, pipeline dispensers, compact devices, air purifiers and filters. The technology evolves quickly and aligns closely with modern expectations such as instant dispensing, integrated systems and bundled packages.

Greenwave 专注于饮水与空气质量管理，产品覆盖 RO、净饮一体机、管线机、小型设备、空气净化器与滤芯等。技术更新节奏快，更符合现代家庭对即时饮用、整体解决方案和组合套餐的需求。

3M is a large global brand whose business spans industrial, commercial and household categories. Water filtration is only a small part of its vast portfolio. Products are stable but updated conservatively, and users often perceive it as buying a “big brand device” rather than a service-driven solution.

3M 是跨越工业、商用与家用的大型国际品牌，净水仅占其庞大业务中的一小部分。产品稳定但更新缓慢，对用户而言更像是“买了个大品牌的设备”，而非服务导向的完整方案。

Aquasana is known for strong filtration technology, especially cartridge-based filters, but its product range is narrow. It does not offer RO, pipeline hot/cold systems or air products, making it suitable mainly for single-point filtration needs.

Aquasana以过滤技术见长，尤其是芯体过滤，但产品线较窄，没有 RO、没有管线冷热系统，也不做空气，较适合只解决单点过滤问题的用户。

Aquars provides Japanese-style service for mainly Japan- and Taiwan-related communities in Shanghai. Its product range is very limited and does not include hot, cold or sparkling-water systems, nor air solutions. It is relatively expensive and highly localized.

阿酷尔偏向为上海的日本／台湾社群提供日式服务，产品线有限，没有冷热水、冰水或气泡水，也不做空气类产品。价格较高且区域性强，更像是为特定圈层设计的方案。

Service Model & Convenience

服务模式与便利性

Greenwave uses its own installation and after-sales teams, ensuring consistent quality and a unified process. It offers proactive filter reminders, relocation support, cross-city services across Shanghai, Beijing, Shenzhen and Guangzhou, and full English communication — providing a highly stable, long-term experience.

Greenwave 采用自营安装与售后团队，质量和流程可控。提供滤芯提醒、搬家衔接、跨城服务（北上广深）与完整英文支持，让用户在长期使用中更省心、更稳妥。

3M relies heavily on dealer networks for installation and support. Service quality varies by region and dealers, and proactive reminders or customized support are not its focus.

3M 大量依赖经销商体系完成安装与售后，服务因地区而异，缺乏主动提醒和个性化支持。

Aquasana works through distributors. The service according to the feedback from users turning to us is not consistent, reply is slow and it’s hard for users to get cross-city support. Also filter replacement costs are also comparatively higher.

Aquasana主要通过国内的分销商来销售跟服务。就部分用户的反馈，分销商中做的比较多的一个响应速度比较慢与服务持续性不是很好，且跨城支持较弱，滤芯更换成本也偏高。

Aquars provides attentive, Japanese-style customer service but is limited to the Shanghai area. Filter replacement frequency is high and maintenance costs are significant, making it suitable only for users who remain long-term in the same region.

阿酷尔的服务细致但只覆盖上海，滤芯更换频繁且维护成本高，只适合长期居住同一城市的特定用户。

Target Users & Cultural Fit

目标客群与文化适配

Greenwave serves international schools, foreign families, embassies, serviced apartments and global companies, offering full English support and clear communication for multicultural environments. Its one-stop water + air model is ideal for users who care about convenience, safety and premium living quality.

Greenwave 的典型用户是国际学校、外籍家庭、使领馆、服务式公寓与跨国企业，具备完整的英文沟通能力，更擅长处理跨文化需求。一站式水＋空气方案特别适合重视便利、安全与生活品质的用户。

3M tends to serve mainstream domestic users who purchase through renovation channels, special stores or online platforms, particularly those who prefer large, globally recognizable brands.

3M 更多面对国内主流用户，常通过装修、专卖店或电商渠道购买，适合偏好国际大牌的国内消费者。

Aquasana appeals to users who trust American filtration technology (with NSF certification) and prefer a technical approach rather than a service-driven one.

Aquasana吸引对美系过滤技术有偏好的用户（有NSF认证），属于更技术导向、对服务要求不高的人群。

Aquars is aligned with users living within Japanese/Taiwanese communities in Shanghai and operates mainly in Japanese + Chinese. It is not always English-friendly.

阿酷尔的用户主要来自上海的日本/台湾社群，以日语＋中文沟通为主，对英语用户不一定友好。

How Users Can Decide

用户应如何选择

Each brand has its strengths: 3M provides global brand recognition, Aquasana delivers solid filtration technology, and Aquars offers Japanese-style attentive service for a very specific community.

每个品牌都有自己的优势：3M 具有全球品牌背书，Aquasana的过滤技术成熟，阿酷尔在日式社群中有稳定口碑。

However, most families and institutions today need solutions that go beyond a single device — they want convenience, stability, proactive service, full English communication, and continuity even when moving cities or upgrading their environment.

然而，现代家庭与国际化机构的需求往往不止于“一台设备”——他们需要省心、稳定、主动服务、多语言沟通，以及跨城市与未来可持续的长期体验。

In these areas, Greenwave provides a more complete and balanced solution across specialization, service depth, product completeness, multilingual support and cross-city consistency.

在这些关键要素上，Greenwave 在专业度、服务深度、产品完整性、多语言支持与跨城连续性方面更加均衡，也更贴近现代国际化用户的真实需求。

Choosing a filtration brand is ultimately choosing a lifestyle. For those who want less complexity and long-term peace of mind, Greenwave is the more comprehensive and dependable one-stop answer.

选择净水品牌，本质上也是选择一种生活方式。对于希望减少麻烦、长期无忧的家庭与机构来说，Greenwave是更全面、更稳妥的一站式选择。
