If you’ve been using the same water (or shower) filter for a few years, it’s worth asking: is it still working the way it should? Filters age quietly—flow slows, taste changes, and performance can drop without obvious signs. That’s why Greenwave is launching an Old-to-New Exchange program: to help you reset daily water quality with a clearer, easier upgrade path.

如果您家的净水器/淋浴净水器已经用了好几年，其实很值得问一句：它现在的效果，还有刚安装时的几成？ 滤芯老化往往是悄悄发生的——出水变慢、口感变差、净化效率下降，但这通常不一定能立刻被看出来。因此，Greenwave推出”以旧换新”活动，希望把您的日常用水重新拉回更稳定、更安心的状态。

Many older systems still work, but performance can drift over time—especially if filters aren’t changed on schedule, parts are worn, or the model is harder to maintain. With some brands, the bigger issue is maintenance: replacement parts can be inconsistent, service can be slow, and once a model changes, it’s easy to get stuck with a device that’s difficult to keep in good condition.

很多旧设备表面上还能用，但净水效果很可能会慢慢变差——滤芯更换不规律、部件老化、或型号维护不方便时更明显。对一些品牌来说，更常见的问题其实是后续维护：耗材配件不稳定、服务响应慢、型号更新后更难延续保养，最后变成“想用好但用不好”的状态。

The exchange program is designed to remove that stress: more stable performance + easier ongoing maintenance + clearer service support, so you get the newest and strongest system on the market which stays reliable long after installation.

以旧换新的目的就是把这些后续压力提前解决：让净化效果更稳定、维护更简单、服务更可预期——设备才能长期保持在“该有的状态”。

1. Drinking Water Purifier → Elavo (recommended first). If your current drinking water system is old, hard to service, or you’re using another brand with unclear maintenance support, switching to Elavo is the most direct upgrade—built for long-term consistency and easier planning.

直饮水机 → 优先升级 Elavo（最推荐）。 如果您现在的直饮水设备年限较长、维护不方便，或者使用其他品牌但后续服务不够稳定，换成 Elavo是最直接的升级路径——更强调长期稳定与维护可控。

2. Shower Filters → ShowerKingX / ClearFallX (feel-it-fast upgrade). Shower water affects skin and hair every day. If you’ve been using an older shower filter (including other brands), the exchange lets you reset performance quickly and get back to a cleaner shower experience.

淋浴净水器 → ShowerKingX / ClearFallX（感受最直观）。 洗澡水对皮肤和头发的影响是每天都能感受到的。旧款或其他品牌换新后，往往能更快把体验拉回到更舒服、更安心的状态。

3. Laundry Filter & Softener. A practical option for long-term users who want steadier performance and less maintenance uncertainty.

洗衣净水/软化。适合使用年限较长的用户，升级后效果更稳定，维护也更省心。

To check your eligibility, message Greenwave with what you’re using now, how long it’s been used, and your city. We’ll recommend the best exchange option and help arrange everything smoothly.
