The best water distillers in Australia: VEVOR 4 L glass for most homes, and when RO is the better buy

A water distiller boils a few litres of tap water, condenses the steam and drips it into a jug, leaving the minerals, salts and fluoride behind in the chamber. The one to buy, if you’ve decided you want one, is the VEVOR 4 L with the glass container: 750 W, a 304 stainless tank, about a litre an hour by VEVOR’s figure, $144.67 at Bunnings Marketplace on 1 November 2026 and also on Amazon Australia. Before you buy it, read the next section, because for most Australian kitchens a distiller is the wrong tool and a benchtop reverse osmosis unit is the right one. We can’t show Amazon prices; the Amazon buttons show today’s.

Questions to ask before buying a water distiller in Australia

• Is my water worth distilling? The national guidelines rate dissolved solids up to 600 mg/L as good for taste, and the fluoride limit is 1.5 mg/L. If your tap water is inside those and you only want better taste, a filter is far cheaper.
• Distiller or reverse osmosis? A distiller makes a few litres at a time and takes hours. For daily drinking water, a benchtop reverse osmosis unit is quicker and cheaper to run.
• Is it approved for sale as an electrical appliance? Energy Safe Victoria says in-scope appliances must display the Regulatory Compliance Mark (RCM). Look for it on the unit or the packaging.
• Who stands behind it? Several of these are sold by third-party marketplace sellers, so check who the seller is. The ACCC says the consumer guarantee usually still applies after a warranty expires.
• How will I clean it? Scale stays in the boiling chamber, and how much depends on your water. The national guidelines say hardness above 200 mg/L brings increasing scaling.

Should you buy a water distiller or a reverse osmosis unit?

For drinking water every day, buy reverse osmosis. A distiller makes about a litre an hour and uses roughly 3 kWh for a 4 L batch; a benchtop RO unit makes a litre in a few minutes on a small pump and drops fluoride and dissolved solids too. The Waterdrop C1S and Philips’ countertop station need no plumbing, which is the same advantage a distiller has.

A distiller wins in three cases. You need genuinely mineral-free water in small amounts: for a CPAP humidifier, a steam iron, a car battery, a humidifier or a sterilising routine, where even RO’s small remaining mineral content leaves scale over time. You don’t want cartridges at all: a distiller’s only consumable is a carbon sachet and some citric acid. Or your water is so high in dissolved solids (some bores) that an RO membrane would foul quickly; RO makers quote feed-water limits, and VEVOR’s distillers list none.

The honest cost comparison, from the makers’ own numbers: VEVOR’s 750 W units are rated at about a litre an hour, so 4 L is roughly four hours and 3 kWh. At 30 to 35 cents a kWh, that’s about $1 a batch, or 25 cents a litre, before you count the time. The 1,750 W VEVOR does the same batch in under three hours but uses the same energy per litre, because the heat needed to boil a litre doesn’t change with the element.

Which water distiller should you buy?

Buy on the container, the batch size and whether you’ll ever use the timer. The VEVOR 4 L glass model (YMK40202 on Amazon) is the pick because the condensate collects in borosilicate glass rather than plastic, the tank and exhaust cover are 304 stainless, it’s the cheapest here, and Bunnings sells it, albeit as a marketplace listing from a third-party seller. VEVOR rates it at over a litre an hour and 24 L a day.

The 1,750 W VEVOR (YMK40230) is the fastest: 1.5 L an hour and about 36 L a day by VEVOR’s listing, a 0 to 99 hour timer, a set-and-actual temperature display, and cut-outs at 115°C and 150°C on the Bunnings listing. It was $182.90 at Bunnings Marketplace on 1 November 2026. The catch is 1,750 W: about a kettle’s draw, but for hours rather than minutes, so put it on a circuit that isn’t already running the toaster. It had one Amazon review when we checked, and a poor one, so we’d buy it from Bunnings for the returns desk.

The VEVOR 6 L (900 W, 1.3 L an hour, 31.2 L a day) is for households that get through distilled water: a CPAP, an iron and a kettle on it, say. Its container is PBT plastic rather than glass and it’s 50 cm tall, so check the gap under your overheads.

The Megahome 943TWS is the brand dental and medical suppliers stock, and it’s the only unit here with a stated Australian warranty (12 months) and a stated batch time (4 L in 5 to 6 hours). It was $408.40 at Adam Dental on 1 November 2026, nearly three times the VEVOR glass model, with a polypropylene jug. Buy it if the warranty and the brand’s record matter more than the price.

The VEVOR with timer and dual display (YMK40207) adds the control panel to the 750 W base; the VEVOR YMK40 is the one-button version with a plastic jug and a 115°C cut-out. Both are fine; neither does anything the glass model doesn’t for the water.

What a distiller does and doesn’t take out

Distillation leaves behind anything that doesn’t boil with the water: dissolved minerals and salts, fluoride, most metals, sediment, and microorganisms, which don’t survive the boil. That’s why it’s one of the two methods we name in our fluoride guide alongside reverse osmosis. What can carry over is anything with a boiling point at or below water’s, which is the reason every unit here ships with activated carbon sachets for the outlet. The makers’ listings say the units remove “dissolved solids, VOCs and almost all other impurities”; we have not tested any of them and can’t put a number on it.

Two things people expect that a distiller doesn’t do. It doesn’t make water “alkaline” or add anything; the result is close to pure H2O, which tastes flat and reads near zero on a TDS meter. And it isn’t a household treatment: 4 L every four hours is drinking and appliance water for a few people, not showers and laundry. Tank and bore households wanting whole-house treatment should read the rainwater tank and bore water guides.

Cleaning, scale and the carbon sachet

Every batch leaves the dissolved solids on the floor of the boiling chamber as scale, and in Adelaide, Perth or on bore water that’s a visible crust within a week. VEVOR supplies citric acid powder and tells you to dissolve the scale regularly; Megahome includes 250 g of cleaning crystals it describes as six months’ worth. Budget ten minutes a week with a kettle of hot water and the powder. The carbon sachets (VEVOR includes three) sit in the outlet and should be changed on the maker’s schedule; 12-packs and 24-packs for “Megahome and other countertop distillers” are sold on Amazon Australia.

Site the unit where the hot, humid exhaust from the fan can escape, and expect it to warm the kitchen; it’s boiling four litres of water, slowly, on the bench.

The one trap

Buying a distiller to “purify” town water. Australian mains water is managed to the NHMRC’s Australian Drinking Water Guidelines, and the things people usually want gone from it, chlorine taste and smell, come out with a $40 jug in seconds. A distiller is the slowest, most power-hungry way to treat water on this site. It earns its bench space when you need mineral-free water for an appliance or you’ve chosen to drink fluoride-free water and don’t want an RO unit’s cartridges; otherwise, the benchtop reverse osmosis guide is the page you want.

What we left out and why

• Luocute 4 L distiller (Amazon Australia). 750 W, 58 to 108°C setting, but a no-name brand with four left in stock and no reviews when we checked.
• VEVOR 4 L distillers at $104.13 to $137.72 (Bunnings Marketplace). The same 750 W family in other finishes; we priced the glass-container model, which was in stock and matched an Amazon listing we could read.
• VEVOR 50 L stills (Amazon Australia, Bunnings Marketplace). Sold for spirits and essential oils; not a kitchen water distiller.
• Fayelong 3 to 20 L electric distiller (Amazon Australia). A laboratory or clinic unit with no household listing details.
• Megahome stainless-and-glass models. Sold in Australia through dental and medical suppliers; we priced the 943TWS, the one Adam Dental listed with a price on the day.
