If you are considering a drinking water purifier, already using one but not fully satisfied, or not sure which brand, model, or rental option is right for you, this article may help you understand a few key points before making a decision.
如果您正在考虑安装直饮水机，已经在使用但不太满意，或不确定应该选择哪个品牌、型号、购买还是租赁，这篇文章可以帮助您先了解几个重要问题。
There are many types of drinking water purifiers on the market, including activated carbon filters, ultrafiltration systems, RO systems, and RO hot-water systems. Some products do not require electricity or wastewater and may claim to keep minerals in the water. RO systems usually produce wastewater, but when properly installed and maintained, they can provide cleaner water compared with many other filtration technologies.
市面上有活性炭直饮水机、超滤直饮水机、RO直饮水机、RO净热一体机等不同类型。有些产品不需要用电，也没有废水，并强调保留矿物质。RO系统通常会产生废水，但在正确安装和定期维护的情况下，相比很多其他过滤技术，RO出水通常更干净，更适合日常饮用和做饭。
Most suppliers will say their purifiers can reduce heavy metals, bacteria, and other impurities. However, the actual performance of different products can vary. Before choosing, it is useful to ask whether the supplier has third-party testing results, real customer feedback, or references from existing users. These can help you understand the product more clearly than product descriptions alone.
大多数服务商都会说自己的直饮水机可以减少重金属、细菌和其他杂质，但不同设备的实际效果并不一样。在选择前，可以询问服务商是否有第三方检测结果、真实用户反馈，或现有客户案例。这些信息通常比单纯的产品介绍更有参考价值。
Choosing a drinking water purifier is not only about choosing a machine. Professional installation, water pressure, countertop drilling, power supply, product connection, and future moving support can all affect long-term use. If you buy online, make sure the supplier can provide reliable after-sales service and professional installers. Poor installation may affect water quality, product performance, and safety.
选择直饮水机，不只是选择一台设备。专业安装、水压情况、台面是否能打孔、电源位置、产品连接，以及未来搬家是否能移机，都会影响长期使用体验。如果在线上购买，也建议确认服务商是否能提供可靠售后和专业安装。安装不专业，可能会影响水质、设备表现和长期使用安全。
Drinking water purifiers need regular filter replacement and maintenance. Before choosing a brand or supplier, it is important to understand whether they can provide continuous service. If the supplier stops providing support later, filter replacement, maintenance, or repair may become difficult.
直饮水机需要定期更换滤芯和维护。在选择品牌或服务商前，建议了解对方是否能提供长期稳定的服务。如果后续服务无法持续，未来换芯、维护或故障处理都会变得麻烦
A good drinking water solution is not only about the machine. Fast response, regular filter replacement, professional support, and reliable after-sales service are also part of the value. Greenwave provides regular filter replacement service every 3–6 months and supports customers with timely communication and onsite service when needed.
一套好的直饮水方案，不只是设备本身。快速响应、定期换芯、专业支持和可靠售后，也都是服务价值的一部分。Greenwave每3–6个月为用户提供滤芯更换服务，并在客户有需要时及时沟通和安排上门支持。
If you plan to stay in China for a long time, buying a purifier can be a good choice. If you are staying for a shorter period, or not sure how long you would stay, rental may be more flexible. Greenwave also provides rent-to-own options, allowing users to enjoy more flexibility without worrying about handling purchased equipment when leaving.
如果您计划长期在中国居住，购买直饮水机是一个合适选择。如果只是短住，或暂时不确定会住多久，租赁会更加灵活。Greenwave也提供租转买选择，让用户在短期居住时不用担心设备处理问题，长期使用也更加划算。
No matter which brand or product you prefer, we recommend arranging an onsite consultation before making a decision. Greenwave provides free onsite consultation and can explain product differences in English, helping you understand which drinking water solution is suitable for your home.
无论您偏好哪个品牌或产品，我们都建议在决定前先安排一次上门查看和咨询。Greenwave提供免费上门咨询，并可以用英文说明不同品牌和产品之间的区别，帮助您更清楚地了解哪种直饮水方案更适合您家。
