A tank, a media bed, and a valve with six or seven positions · review
The smallest and cheapest system here, with a transparent lid so the bed can be watched, a set of filter balls in the box, and a TÜV Rheinland certificate quoted with its ID number.
The bottom line The small one, and unusually honest about being small. Two flow figures, a visible bed, the medium in the box and a certificate with a number are four things the rest of this shelf mostly skips. What it will not tell you is how many valve positions it has, what the pump draws or what hose it takes — and on a sand system the valve is the thing you operate every week.
A 16-litre sand filter system with a pump, supplied with a filter ball set in 100 % recyclable polyethylene. Throughput is stated at up to 2 700 l/h with a maximum delivery of 4 500 l/h. The lid is transparent so the filtering can be watched and the level of soiling seen.
The system is stated TÜV Rheinland certified, with the ID number 1111297578, and is described as suitable for pool, spa, hot tub or aquarium.
2 700 l/h throughput and 4 500 l/h maximum delivery. Two numbers rather than one, which is a rarer thing on this shelf than it should be.
What they are not is a turnover. Turning a pool over means passing its whole volume through the medium, and that depends on the pool. The page prints the maker’s figures and the arithmetic stays visible.
A filter bed is opaque in every sense: nothing about it is visible until the pressure gauge moves, and a channelled bed does not move the gauge at all.
A transparent lid is the only direct look at the medium anybody on this shelf offers, and it costs nothing.
Valve positions — the function list that a sand system is operated through, and which seven other systems here publish. Pump power in watts. Hose size. Tank diameter.
Four absences on a listing that does publish two flows, a medium, a certification and an ID number. It is a particular shape, and the page records it rather than filling the rows in.

The American, British, French, Italian and Spanish Amazon stores gave back nothing, so the buy button there lands on a search instead of a blank page.

Because a filter bed gives no other sign of its state until the pressure rises. Seeing the medium and the water above it turns a guess into a look. It is the only system in this family to offer it.
They are lighter, the charge is smaller, and makers claim they do not cement into channels the way old sand can. What nobody on this shelf publishes is a measured fineness for either. This listing states polyethylene and recyclability and no micron figure.
That a certificate exists and can be looked up — the ID is quoted in the listing. It is a traceable claim rather than a badge, which is unusual here. What the certificate covers is a matter for TÜV Rheinland rather than for this page.
A small pool or a spa where the bed being visible matters more than the flow

10 200 l/h, 400 W, 20 l tank, 60–65 dB(A)/m
The only filter system on this shelf that publishes a noise level with a distance — 60 to 65 dB(A) at one metre — alongside 10 200 l/h from a 400 W pump and 800 g of filter balls.
Best for: A system sited near a terrace, where the decibel figure is the deciding one
6 056 l/h pump, 4 920 l/h through-flow, 38.5 cm tank, 36 kg sand
The listing that states its media requirement in full — 36 kg of #20 quartz sand or 1 000 g of filter balls, neither included — alongside two flow figures, a 38.5 cm tank and both hoses in the box.
Best for: A first sand system, where knowing exactly what else to order is worth more than a headline flow
9 000 l/h, 7.5 m head, 250 W, 7-way, 32/38 adapter
A 250 W system publishing both ends of its curve — 9 000 l/h and a maximum head of 7.5 m — with a seven-position valve, a pressure gauge, IPX5 and adapters for both hose sizes.
Best for: A mid-sized pool where knowing the head before ordering matters
