Our verdict
TOP PURE suits US households ready to fit an under sink reverse osmosis unit themselves and to judge it on running cost, since filter changes work out at $87.60 a year. Cartridge life is the strongest number in its favour, and the short warranty is the detail to read before ordering.

Pros and cons
Pros
- Cartridge life of 4,000 litres is a strong showing, so refills come round less often than with shorter rated cartridges.
- Filter changes cost $87.60 a year, which keeps the running bill modest once the system is fitted.
- The refrigerator cartridge carries an 42 and 53 NSF listing, and the under sink reverse osmosis system is certified by IAPMO R&T for low lead.
- PFAS and lead reduction is stated for the reverse osmosis line.
- The tankless under sink reverse osmosis system is priced from $49.99, which puts under sink reverse osmosis within reach of an ordinary kitchen budget.
Cons
- Support runs on email and help centre, so there is no phone line listed for installation day.
- Installation is required, so the system has to be plumbed in under the counter before it works.
- The catalogue is listed for US only, so buyers in other markets face different terms and no local stock.
- Cover runs 1 year on a unit that has to be fitted under a sink rather than unboxed onto a worktop.
Who it suits
- US households that want their own reverse osmosis water at the kitchen tap and can arrange a fitting, since installation is required.
- People replacing a GE XWF refrigerator cartridge who want a part carrying an 42 and 53 NSF listing.
- Families planning a modest yearly filter bill, with filter changes at $87.60 over a year.
Who should look elsewhere
- Buyers who want a countertop unit and no under sink work: IBBL is a countertop system (countertop).
- Shoppers who want more under sink tankless formats under one brand: Waterdrop lists the X Series alongside further tankless and undersink reverse osmosis systems.
- People who want a wider drinking water catalogue from a single name: Culligan Consumer Products lists Aquasential Smart, Aquasential and Aquasential Tankless reverse osmosis systems.
Pricing
Buying the tankless under sink reverse osmosis system is a single purchase at $49.99. Nothing in the outlay needs renewing, and the money you pay afterwards is for filters rather than for a plan. Replacement cartridges across the range run $49.99 each, and a full year of filter changes comes to $87.60. So the price at entry and the price afterwards are separate decisions. The first sets the budget for the unit and its fitting, the second sets what leaves your account every year for as long as you keep drinking the water. Readers who compare systems on sticker price alone end up comparing the smaller number. The cartridge line is the one that repeats. $49.99 is what you meet again on every refill, so a household running a lot of filtered water will feel it more than an occasional drinker, and $87.60 is the figure to put into a household budget rather than the entry price.
Where it sits among rivals
TOP PURE sits in the middle of the field on the numbers that drive running cost, and above the middle on the one that drives convenience. On price from it ranks 15 of 52 brands tracked here, and on filter cost a year it comes out at 15 of 46. Cartridge life is the strongest line, at 9 of 26, which is where the range pulls ahead of brands with shorter rated filters. Cartridge price is the weaker one, at 22 of 50, so replacement cost is the part to allow for in your own sums. The practical reading is that TOP PURE is a steady buy on money and a better one on longevity. You are not chasing the cheapest kit, and replacement cartridges are not the heaviest line either, but the litres each cartridge covers leave a longer gap between refills than the price table alone would suggest.
What it does well
The figure that separates TOP PURE from most systems beside it is cartridge life of 4,000 litres, because a longer rated life means fewer replacement cycles and less time spent under the sink with a spanner. On what it treats, the reverse osmosis line is stated to reduce PFAS and lead, which is the claim that matters most when you are filtering tap water you did not choose. Practical notes sit alongside that. Installation is required, so the under sink unit is plumbed in under the counter rather than set on the worktop, and anyone without a compression fitting or a wrench ends up paying a plumber for the privilege. Warranty cover runs 1 year, short enough that the returns terms are worth reading before you commit to a fitted kitchen rather than a tap-mounted jug.
Who runs it
TOP PURE trades as TOP PURE and is headquartered in the US, so its prices, warranty terms and product range are all built for that market (US). Products carry the ICEPURE name on the model label while the company itself registers as TOP PURE, which matters if you are matching a replacement cartridge against the part number in your fridge. Support is the part worth planning around. Contact runs on email and help centre, so you have email and a help centre to work with rather than a number to call. For an under sink system that is workable, since most questions come down to fitting and to ordering the right cartridge, but anyone who wants a voice on the phone during installation will have to work through written help.

Frequently asked questions
How much does the system cost to buy?+
The tankless under sink reverse osmosis system is priced from $49.99, and that figure covers the hardware itself. It is a single purchase rather than a subscription, so nothing falls due at renewal. The smaller recurring outlay is cartridges, and that is the number to keep in mind when you line the system up against rivals.
What do replacement filters cost?+
Replacement cartridges for the range are $49.99 each, and a full year of filter changes comes to $87.60. Put those side by side when you compare brands, because a modest system price can still work out expensive across a year of use. Cartridge cost is the line that repeats on every refill, so it deserves more attention than the entry figure.
How long does a cartridge last?+
The rated cartridge life is 4,000 litres of filtered water before a change is due, and that figure decides how often you order. On cartridge life, TOP PURE ranks 9 of 26 on the site, so it sits above the middle of the brands tracked. A longer rated life means fewer refills and less stored under the sink.
Is the water certified, and what does the certification cover?+
The refrigerator cartridge carries an NSF listing under the TOP PURE name to 42 and 53, covering chlorine, taste, odour, fine particulate, lead, mercury and cyst reduction. The under sink reverse osmosis system is separately certified by IAPMO R&T for low lead. That listing sits with the manufacturer name, which is worth matching against the model number in your fridge.
Does it reduce PFAS and lead?+
PFAS and lead reduction is stated for the reverse osmosis line, which matters if you are treating tap water you did not choose. Lead also appears in the certification picture: the under sink reverse osmosis system is certified by IAPMO R&T for low lead, and the refrigerator cartridge is NSF listed to 42 and 53 with lead and mercury among its claims.
Do I need to install it myself?+
Installation is required for the under sink system, so it has to be plumbed in rather than simply placed on a worktop. If a compression fitting is beyond you, a plumber is the straightforward route. Support runs on email and help centre, so the help centre and email are where fitting guidance and matching cartridge part numbers live.
Can I buy it outside the US?+
TOP PURE is headquartered in the US (US) and its products are listed for US only, so pricing, warranty terms and shipping are framed around that market. Anyone ordering from another country should check the terms before committing, because a 1 year warranty running in the US may not travel with an international order.
What support and warranty do I get?+
Support runs on email and help centre, which is email and a help centre, and warranty cover is 1 year. On a product that has to be plumbed under a sink that combination is worth planning around: most questions will be about fitting, and written help is the route available.
