VEVOR 4L 750W Countertop Water Distiller: features, specs and who it suits

The VEVOR 4L Water Distiller is a countertop appliance that makes distilled water from tap water. It heats the water to steam, cools the steam back to liquid and collects it in a glass pot. People use distilled water for drinks, coffee and tea, and for appliances and equipment that call for it.

How distillation works

Distillation boils water and condenses the steam, leaving most dissolved solids behind in the boiling chamber. VEVOR says the machine can remove most impurities from tap water. In general, that is why distillers leave a mineral residue, or scale, in the tank that needs periodic cleaning. A distiller is a slow, batch process rather than a tap-style filter.

Capacity and speed

The 750W heating element runs at a rate that VEVOR gives as over 0.3 gallons (1 litre) per hour. The tank holds 4 litres (1.1 gallons), and VEVOR says the machine can distil up to 7.2 gallons (24 litres) in a day. That daily figure assumes repeated cycles, so most households will simply fill and run it when they need water. The machine is 10.6 x 9.4 x 16.1 inches (about 27 x 24 x 41 cm) and weighs 12.1 lb (about 5.5 kg), so it fits on a counter.

Materials in contact with the water

VEVOR lists a 304 stainless steel interior tank and a collection container made from high borosilicate glass. It says all parts in contact with water are food-grade. Borosilicate glass is widely used in kitchenware and laboratories because it handles heat well and doesn't hold flavours.

Cooling fan and exhaust

Steam needs to condense, which means the unit has to shed heat. VEVOR says the upgraded four-blade fan is aluminium instead of plastic, and the exhaust cover is 304 stainless steel, to help heat dissipation and service life. Expect some fan noise and warm air during a cycle, so put the unit where it has room to breathe.

Carbon packs and descaling

The machine comes with replacement activated carbon packs, and VEVOR recommends changing them regularly. Activated carbon is typically used at the outlet to adsorb odours and some volatile compounds that can come over with the steam. VEVOR also suggests citric acid to remove scale and regular cleaning to keep the interior clean. Hard water leaves more scale, so descaling may be more frequent.

Where it is used

VEVOR describes uses in homes, offices, laboratories and clinics, and for drinking water and coffee brewing water. Check any specific requirement of your own, for example the water quality an appliance's maker asks for, before relying on it.

What to check before you buy

• Volume: at roughly a litre an hour, consider how much distilled water you need and how long you can leave it running.
• Counter space and height: it stands about 16 inches (41 cm) tall; check the clearance under cabinets.
• Power: 750W for several hours; follow the manual and don't leave it unattended unless the manual says it's fine.
• Cleaning: plan for descaling and for replacing carbon packs.
• Noise and heat: the fan and steam make noise and warmth.
• Taste: distilled water tastes flat to some people, since it contains almost no minerals.
