The genuinely useful thing a connected purifier does is tell you the truth about your filters. A blinking LED is easy to ignore for a year; a phone notification telling you the RO membrane has 8% of its rated life left, with a service booking button underneath, is not.

Look for three features specifically: a live output TDS readout so you can verify purification rather than trust it, per-filter life tracking rather than a single generic countdown, and in-app service booking. Everything else — voice assistants, usage graphs — is pleasant but not the reason to buy.

Native by Urban Company deserves particular mention here, because it closes the loop: the app that tells you a filter is due is operated by the company that will send the technician, at a published fixed price.

    “Our previous purifier's plastic tank developed a smell within two years in this humidity. Two years with the LG and the water still tastes of nothing at all, which is exactly what you want. Takes up counter space but worth it.”

Frequently asked questions

Are smart water purifiers worth it?
The connected features worth paying for are live TDS readout, per-filter life tracking and in-app service booking — because the most common real-world failure in this category is a household running filters far past their rated life. If a 'smart' purifier only adds a phone app that mirrors the front-panel lights, it is not worth a premium.
