Ecosoft SPARK Replacement Filter for Countertop Reverse Osmosis Systems
Restore the filtration performance of your Ecosoft SPARK countertop RO system with the genuine replacement filter cartridge, designed to help maintain cleaner taste, reduced odour and consistent day to day water quality.
Designed for the Ecosoft SPARK Countertop RO System
This replacement cartridge is made specifically for the Ecosoft SPARK smart countertop reverse osmosis system. It is not a generic filter, so it should only be used with the correct compatible SPARK model.
Replacing the cartridge on time helps protect water quality and keeps the system working as intended, rather than relying on an old filter that has reached the end of its service life.

Genuine Replacement
Original Ecosoft replacement filter for the SPARK system.
4 Stage RO Filtration
The SPARK replacement cartridge uses 4 stage reverse osmosis filtration to help reduce sediment, chlorine, organic compounds, TDS and unwanted taste or odour.
Up to 24 Months Use
The cartridge is designed to provide up to 24 months of use or around 4,000 litres of purified water, depending on water quality and household usage.
Twist Lock Replacement
The filter is designed for quick, tool free replacement, with no plumbing work and no complicated installation steps.

Why Filter Replacement Matters
Your SPARK system depends on the internal cartridge to do the hard work. Once the filter reaches the end of its service life, water quality, taste and system performance can start to drop.
Changing the filter at the correct interval is the simplest way to keep your countertop RO system producing cleaner, fresher tasting water without replacing the whole unit.
Cleaner Taste, Lower Odour and Reduced TDS
The SPARK replacement filter is built to reduce up to 99.8 percent of impurities, including sediment, chlorine, organic compounds, dissolved salts and unpleasant taste or odour.
That makes it a sensible maintenance part for households using the Ecosoft SPARK every day for drinking water, hot drinks, cooking or bottle refills.

Ecosoft SPARK Replacement Filter FAQs
Is this the correct filter for the Ecosoft SPARK?
Yes. This cartridge is designed for the Ecosoft SPARK countertop reverse osmosis system. It should not be used as a universal replacement filter for unrelated RO systems.
How long does the SPARK replacement filter last?
The filter is designed to last up to 24 months or around 4,000 litres, depending on your water quality and how much purified water your household uses.
Can I replace the filter myself?
Yes. The twist lock design allows the cartridge to be changed without tools, plumbing changes or professional installation.
What happens if I do not replace the filter on time?
Leaving an expired cartridge in place can reduce water taste, filtration performance and overall system consistency. Replacing it on schedule is basic maintenance, not an optional extra.
