How Do I Know My Water Purifier Is Working?
Use TDS readings, filter-life reminders and everyday performance to keep track of your RO water purifier.
A water purifier does most of its work out of sight. The filters sit inside the appliance, water moves through sealed tubing, and the reverse-osmosis membrane is hidden inside its cartridge.
That does not mean you have to rely on guesswork. A modern RO purifier can make its performance visible through its TDS reading, filter-life status and everyday operation.
Start With the TDS Reading
TDS stands for total dissolved solids. An RO membrane reduces dissolved material as water passes through it, and the appliance's TDS reading gives you a convenient way to see that performance.
The most useful approach is to become familiar with your purifier's normal reading. Source water, temperature and recent use can all move the number, so a single universal target is less useful than a clear, consistent pattern from your own appliance.
If the reading changes sharply or remains unusually high, check the filter status and follow the purifier's rinse instructions. Contact Velta Singapore if the change continues.
Keep Filter Life in View
Every filter has a working life. Velta purifiers track cartridge use and provide a replacement prompt on the appliance.
Follow the prompt together with the published capacity or time interval, whichever comes first:
| Purifier | TDS display | Filter guidance |
|---|---|---|
| HydroSpark+ | One TDS value in the settings interface | 4-in-1 cartridge: 4,000 L / 24 months |
| HydroForm+ | Live TDS reading | PAC: 2,100 L / approximately 6 months; RO + ACF: 3,000 L / 1 year |
| HydroView+ | Inlet and outlet TDS at the faucet | CF: 4,000 L / 12 months; RO: 8,000 L / 24 months |
The appliance calculates filter status from use and time. It turns a maintenance date that is easy to forget into something you can check whenever you use the purifier.
Notice Everyday Changes
The display is only one part of the experience. Pay attention when:
- water flow becomes noticeably slower;
- taste or odour changes unexpectedly;
- the appliance displays a filter or fault alert;
- the purifier has been unused for an extended period;
- a refill tank, drip tray or outlet needs cleaning.
Use the model's rinse or restart instructions after a long break. HydroSpark+ users should also refresh the refill tank where applicable, while connected models should be allowed to complete their prescribed rinse cycle.
What Each Velta Purifier Shows
HydroSpark+
HydroSpark+ provides one TDS reading through its settings interface. Its filter-life status keeps the 4-in-1 cartridge replacement point visible alongside the rest of the appliance controls.
HydroForm+
HydroForm+ includes a live TDS display, filter-life percentage and an auto-rinse control. Its PAC and RO/ACF cartridges have separate working lives, so the display helps you keep track of each one.
HydroView+
HydroView+ shows inlet and outlet TDS together at the faucet. It also keeps the CF and RO cartridge status separate and automatically flushes after an extended period without use.
A Simple Ownership Routine
- Check the TDS reading occasionally and learn what is normal for your purifier.
- Follow the filter-life indicator instead of relying on memory.
- Replace each cartridge at its prompt, capacity or time interval.
- Use the prescribed rinse cycle after a filter change or long break.
- Contact Velta Singapore when an unusual reading, flow change or alert continues.
The result is straightforward: RO performs the filtration, the display lets you see its day-to-day performance, and the filter reminder tells you when the purifier needs attention.

Frequently Asked Questions
Does every Velta purifier show TDS?
Yes. HydroSpark+ shows one value in settings, HydroForm+ provides a live TDS reading, and HydroView+ displays inlet and outlet readings together.
Should the TDS number always stay exactly the same?
No. Source water, temperature and recent use can move the reading. Look for a consistent normal range and investigate a sharp or lasting change.
When should I replace the filter?
Follow the appliance prompt and the published capacity or time interval for the cartridge, whichever comes first.
What should I do after a holiday?
Follow the model's rinse or restart instructions before returning to normal use. Refresh removable source water where applicable and let the appliance complete its prescribed rinse cycle.
