Can you make dehumidifier water drinkable by filtering or boiling it?

Boiling kills microorganisms but does nothing for dissolved metals or chemicals, and it does not fix the open bucket or the non-food-grade coil. An under-sink carbon and RO stack plus UV would be needed to approach potability, and by then the cost is close to buying a real AWG that also does it automatically.

How much water does an atmospheric water generator make compared with a dehumidifier?

Output depends on humidity and temperature, not on the badge on the front. A 20 L/day unit such as the Aquaura A20 delivers its rated output above roughly 80 percent relative humidity and falls to 20-40 percent of rating between 20 and 40 percent RH. A typical 30-50 pint dehumidifier makes about 2-5 litres a day under good conditions — below what most households need just for drinking and cooking.

Is the wastewater from either machine safe for plants?

Yes for ornamental plants. Both condensates are low in minerals and free of chlorine. Do not use either on edible crops without testing, and expect more mineral build-up over time from the less filtered source.

Which one uses less electricity for the water it produces?

The AWG, by a wide margin. Purpose-built cooling-condensation machines run near 0.3-0.5 kWh per litre, while conventional dehumidifiers typically need roughly 0.5-1.5 kWh for the same litre because they keep running regardless of how much water the air can still give up.

AWG vs Dehumidifier: Which Makes Drinking Water?

Short answer: both machines condense water out of the air, but only one is built to make drinking water. A dehumidifier is designed to dry a room; an atmospheric water generator (AWG) is designed to fill a glass. That single difference in design goal drives every other difference — food-contact materials, sealed reservoir, multi-stage filtration, UV sterilisation and automatic sanitising cycles.

The same machines are sold and searched for under several labels — air water generator, air-to-water machine, water-from-air machine and atmospheric water maker all describe this equipment. Whichever term brought you here, everything below applies identically.

The 60-second comparison

Criterion	Atmospheric water generator	Household dehumidifier
Design goal	Produce safe drinking water	Reduce room humidity
Air intake filtration	10 micron dust filter + activated carbon pre-filter	Basic washable dust screen
Wet-path materials	Food-grade stainless steel or BPA-free polymer	Industrial-grade coil and bucket, not rated for food contact
Condensate handling	Sealed reservoir, never open to room air	Open collection bucket
Purification train	Sediment, carbon, 0.2 micron membrane, mineral balancing, UV-C	None
Sanitising cycle	Automatic hot-water or ozone cycle	Manual cleaning only
Drinkable output	Yes, straight from the tap	No — not without treatment

Why dehumidifier condensate is not potable

Condensed water starts out clean; everything that happens after condensation is what makes it unsafe. The condensate drips over a coil that carries dust, then sits in an open bucket in a warm room. The three practical risks are biofilm forming on surfaces, metals picked up from non-food-grade solders and coil coatings, and airborne contaminants that settle into an open bucket between cycles.

Published energy comparisons put ordinary portable dehumidifiers at roughly 0.5 to 1.5 kWh per litre of condensate — several times less efficient than purpose-built cooling-condensation AWGs, which typically run around 0.3 to 0.5 kWh per litre. In other words, the dehumidifier is the worse machine even on the one metric it ought to win: water produced per unit of electricity.

What an AWG does differently, stage by stage

The ZENIUS process is documented in full on our AWG technology page:

Air intake — a centrifugal fan pulls ambient air through a 10 micron dust filter and then an activated carbon pre-filter, stripping particulates and VOCs before any condensation happens.
Condensation — the clean air crosses an evaporator coil held at 4–8 °C, well below the dew point at normal indoor humidity, and water vapour condenses onto it.
Purification — sediment filtration, activated carbon, a 0.2 micron membrane and a mineral balancing cartridge that lifts pH to roughly 7.5–8.5 for taste.
Sterilisation and storage — a germicidal UV-C lamp handles remaining microorganisms, then the water sits in a sealed food-grade tank until dispensed.

None of those stages exists in a dehumidifier, and none of them can be retrofitted economically. Adding a proper post-filter stack to a consumer dehumidifier costs close to the price difference between the two appliances and still leaves you with the open bucket and the non-food-grade wet path.

Where each one actually belongs

Buy a dehumidifier if your problem is damp, mould or condensation on windows. Use the condensate on houseplants — it is genuinely fine for that.
Buy an AWG if your problem is drinking water: no safe municipal supply, bottled water cost or plastic waste, or resilience when supply fails.

For coastal and high-humidity sites — including most of the Gulf — the productivity gap between the two is large, because an AWG is tuned to keep producing at real-world humidity rather than simply to pull the room down to a setpoint. See AWG sizing for the UAE and for Saudi Arabia.

Bottom line: the two machines share a physics principle, not a purpose. If the water is going into a kettle or a glass, you want an atmospheric water generator.
