Note: Water distillers remove contaminants effectively, but they also strip minerals from water. If you have specific health concerns about your water supply or mineral intake, consult a qualified professional before making distillation your sole water source.
Home water distillers work by boiling water, collecting the steam, and condensing it back into liquid, leaving behind dissolved solids, heavy metals, and most organic contaminants. The result is among the purest water you can produce at home, without filters that require frequent replacement.

Megahome MH943SBS — Best Countertop Overall
The Megahome MH943SBS is the most widely recommended home distiller at its price point. The stainless steel boiling chamber and glass collection bottle keep the water path free of plastic contact, which matters for taste and purity. It produces one gallon in about 5.5 hours and shuts off automatically when the cycle is complete. The activated carbon filter sachets improve taste by removing volatile organic compounds (VOCs) that survive distillation. Replacement parts and carbon sachets are widely available. Easy to clean and maintain, making it the most sensible starting point for first-time distiller buyers.
Pure Water Mini-Classic CT — Best Build Quality
The Mini-Classic CT is assembled in the USA with all-stainless construction and a reputation for lasting decades. It is a batch distiller that produces approximately 0.8 gallons per cycle at a slower pace, but the build quality is in a different category from mass-market alternatives. The unit runs quietly and uses a glass collection vessel. Pure Water’s customer service and parts availability are often cited as standout features. At $430 it is the most expensive on this list, but buyers who have owned one for 10 or 15 years consistently report it as one of their best home appliance purchases.
CO-Z 4L Distiller — Best Budget Pick
The CO-Z 4L distiller handles roughly one gallon per cycle and costs well under $100, making it the entry point for anyone who wants to try distillation without a large commitment. The boiling chamber is stainless steel, and the collection bottle is BPA-free plastic. Auto shut-off and overheat protection are included. At this price, the build is lighter and the lifespan shorter than premium options, but for supplemental use, travel, or preparedness storage, it gets the job done. Carbon filter pods are included. A reasonable purchase for low-volume use or as a trial before committing to a higher-end unit.
H2O Labs Model 100SS — Best All-Stainless Interior
H2O Labs’ Model 100SS keeps the entire water-contact path in stainless steel, including the carafe, which is a distinguishing feature in this price range. The 1-gallon capacity produces clean, consistent output and includes a coconut shell activated carbon filter to polish the final taste. The unit is straightforward to operate and clean. At around $200 it sits in the middle of the market and delivers a step up in material quality compared to units with plastic collection bottles. A solid choice for buyers who prioritize avoiding any plastic contact with their drinking water.
Waterwise 4000 — Best for Moderate Output
The Waterwise 4000 produces approximately one gallon every 4 hours, making it the faster option on this list. The food-grade plastic housing and glass collection bottle keep costs down relative to all-stainless alternatives. An activated carbon post-filter is included. The unit runs continuously until the boiling chamber is empty and shuts off automatically. Waterwise has a long history in home water treatment, and the 4000 has a track record of reliable operation with minimal maintenance. A practical choice for households that want a slightly higher daily output without stepping up to commercial-grade equipment.
How to Choose a Water Distiller
Start with output volume. A single person or couple will manage fine with a standard 1-gallon batch distiller; larger households may want to run the unit twice daily or consider a continuous-feed model. Check the materials in the water path: stainless steel boiling chambers and glass or stainless collection vessels are preferable to plastic for both taste and purity. Look for an activated carbon post-filter stage to remove VOCs, which distillation alone does not fully eliminate. Auto shut-off is a safety essential. Finally, factor in running costs: a typical 700-800 watt distiller adds roughly $0.08 to $0.12 per gallon in electricity.

Frequently asked questions
Is distilled water safe to drink every day?+
Distilled water is safe to drink. It contains virtually no minerals, which some people supplement separately or address by adding a mineral concentrate to the distilled water. The World Health Organization notes that long-term consumption of very low mineral water may not provide the trace minerals some people get from tap water, so consider your overall diet when making this choice.
How long does it take a home water distiller to produce a gallon?+
Most countertop distillers produce one gallon in approximately 4 to 6 hours. This depends on the heating element wattage and ambient temperature. Units with larger boiling chambers or higher wattage run faster but use more electricity. Plan to run the distiller overnight or during off-peak hours for best results.
