01RO in every core purifier
More than carbon alone
Velta’s core purifiers use RO to reduce dissolved matter beyond what carbon filtration handles.

Velta’s core purifier range uses RO for finer filtration than carbon alone. Built-in TDS readings let you check performance, while filter-life reminders tell you when upkeep is due.

The Velta difference
Better water. Visible performance. Simple upkeep.
RO goes beyond carbon filtration, TDS lets you check performance, and filter reminders tell you when replacement is due.

Know when to change the filter
Each core purifier keeps filter life visible and tells you when its cartridges are due for replacement.
Three ways to choose Velta
Start with the water you want.
The right model depends on the water you want—sparkling, temperature-controlled or ambient—and whether it belongs on the counter or under the sink.
Countertop · sparkling and temperature-controlled
HydroSpark+
RO-filtered sparkling, cold, ambient and hot water.
Sediment · pre-carbon · RO · post-carbonView HydroSpark+ →Countertop · temperature-controlled
HydroForm+
Connected hot, cold and ambient RO water.
PAC composite · RO + ACF · outlet UVCView HydroForm+ →Under-sink · clear worktop
HydroView+
Ambient RO drinking water with a separate filtered rinse path.
Composite pre-filter · RO · post-carbonView HydroView+ →Malaysia range note: HydroFirst+ is an additional plug-and-fill RO purifier with inlet/outlet TDS, separate PCB and RO replacement indicators, and a replacement interval of up to 3,600 L / 12 months.
How the stages work together
Every filter has a job.
Sediment filters catch particles, carbon improves taste and smell, RO reduces dissolved matter, and the final stage finishes the water.
Catch the particles
Sediment and composite pre-filters catch suspended particles and help protect the RO membrane.
Improve taste and smell
Activated carbon reduces chlorine-related tastes and smells before or after the RO stage.
Reduce dissolved matter
Pressure moves water across the RO membrane, separating filtered water from a reject stream.
Give the water a final polish
Depending on the purifier, post-carbon, ACF or outlet UVC completes the treatment path.
Meet the filters & membranes
The filters inside each purifier.
All three Velta core purifiers use reverse osmosis, with cartridges and replacement schedules designed for each model.
4-in-1 composite cartridge
HydroSpark+
Sediment · carbon · RO membrane · post-carbonOne integrated cartridge prepares the water, performs RO separation and refines taste before dispensing.
- Replacement schedule
- 4,000 L / 24 months
PAC + RO / ACF cartridges
HydroForm+
PAC composite · RO membrane + ACF · outlet UVCThe PAC cartridge prepares the water; the RO and activated-carbon fibre cartridge separates and finishes it before the outlet stage.
- Replacement schedule
- PAC 2,100 L / ~6 months · RO + ACF 3,000 L / 1 year
CF + RO cartridges
HydroView+
Composite pre-filter · RO membrane · post-carbonThe composite filter pre-treats the water before it reaches the RO cartridge.
- Replacement schedule
- CF 4,000 L / 12 months · RO 8,000 L / 24 months
Each cartridge is due at the appliance reminder, stated capacity or time interval, whichever comes first.
How to check purifier performance →Why reverse osmosis
What RO changes in your glass.
RO reduces dissolved matter that carbon alone does not address. The surrounding stages catch particles, improve taste and finish the water.
01Physical particles
Tiny particles, filtered out
Membrane filtration creates a fine physical barrier for suspended particles and microscopic matter, including microplastics.
02Dissolved matter
Less dissolved matter
RO reaches beyond sediment filtration to reduce dissolved salts, TDS and selected metals.
03Persistent chemicals
Helps reduce PFAS
PFAS are persistent synthetic chemicals often called “forever chemicals”. The US EPA lists point-of-use RO among technologies that reduce certain PFAS compounds.
04Taste profile
Better taste and smell
Activated carbon reduces chlorine-related taste and odour for cleaner-tasting water.

Frequently asked questions
Choosing a Velta RO water purifier.
01Why does Velta use reverse osmosis in every core purifier?
+
RO can reduce a broader range of dissolved substances than sediment and carbon filtration alone. Velta pairs it with pre-filters that protect the membrane and a final stage that refines the water.
02How can I see my purifier working?
+
The TDS reading on the appliance gives an immediate view of RO performance. HydroSpark+ shows one value in settings, HydroForm+ provides a live TDS reading, and HydroView+ compares inlet and outlet readings at the faucet.
03Which Velta water purifier should I choose?
+
HydroSpark+ provides sparkling, cold, ambient and hot water; HydroForm+ provides connected hot, cold and ambient water; HydroView+ supplies ambient drinking water from an under-sink system with a clearer worktop. HydroFirst+ is the compact Malaysia-only option; confirm its current details on the product page.
04Do all three core purifiers use the same filters?
+
No. All three use reverse osmosis, but their cartridges and final stages differ. Each model has its own filters, replacement schedule and water output.
05What does the 0.0001 µm figure mean?
+
It is the nominal scale of the reverse-osmosis membrane used across the core range. It describes how finely the membrane is engineered to separate water from dissolved and microscopic matter.
06Does reverse osmosis remove everything from water?
+
No single filter removes everything. RO reduces a broad range of dissolved substances, while sediment, carbon and model-specific finishing stages do the rest of the work.
07How do I maintain a Velta water purifier?
+
Follow the appliance reminder and replace cartridges at the stated capacity or time interval, whichever comes first. Timely replacement keeps every stage working as intended.
