Alternatives to LEDI.
An Australian manufacturer of small portable 12 V systems built around off-the-shelf filters and a standard 2521 membrane, aimed at small cruisers and off-grid use. If you are looking past it, the brand that overlaps most of its output range on the least energy is Schenker, from 3.7 Wh per litre.
If you were looking at…
Each LEDI system paired with the closest system another brand makes, by output — the thing that actually makes two units substitutable. Energy and price differences run in whichever direction the figures put them.
| LEDI | Closest alternative | Energy | Price |
|---|---|---|---|
| Scout SW20 20 L/hr · 10.0 Wh/L | Spectra Ventura 150 Deluxe 24 L/hr · 4.5 Wh/L | −5.5 Wh/L | — |
Energy column: negative means the alternative uses less per litre. Price column: positive means it costs more.

Common questions
- What is a good alternative to LEDI?
- On the published figures, Schenker: it covers a similar output range and reaches 3.7 watt-hours per litre at its best, against 10.0 for LEDI. Which is right still depends on your power source and whether the system can be installed on your boat — the table above pairs each LEDI model with its closest match by output.
- Is LEDI worth the money?
- On energy, 0 of its 1 systems use less per litre than the nearest system another brand makes at similar output — none. On price, 0 of 1 undercut that same alternative. Those are different questions and a range can win one while losing the other. We do not rate build quality, reliability or support, because we have not tested these machines; what we can compare is what the manufacturers publish, and that is what the table above does.
- Who sells LEDI in Australia?
- 1 verified business, including LEDI Watermakers. Availability matters as much as specification — a system nobody services near you is a worse buy than one that is a little thirstier.
Alternatives to the other brands
How “closest” is decided. Nearest by rated litres per hour from a different brand, with efficiency breaking ties. That is a deliberately mechanical rule: it stops the page becoming a list of whatever we would rather sell you, and it matches how people actually shop — first for enough water, then for what it costs to make. Prices are indicative and exclude freight and installation. Methodology.
