## Product: Waterwise 4000 Distiller
**Brand:** Water Wise

## Pros
- Produces clean, great-tasting distilled water that many users find refreshing and superior for drinking, coffee, and tea.
- Effectively removes impurities including sulfur, toxins, and contaminants, making it ideal for humidifiers and CPAP/BiPAP machines.
- Durable and reliable with consistent performance noted over many years and hundreds of gallons distilled.
- Saves money over time by eliminating the need to buy and carry bottled distilled water.
- Operates fairly quietly without being distracting during the roughly 4-5 hour distillation cycle.
- Includes effective cleaning methods and accessories, like a specific cleaning powder and brush, to maintain longevity and reduce mineral buildup.
- Helps improve health by supporting toxin removal and may enhance circulation and blood pressure regulation when used regularly.

## Cons
- The included glass pitcher design is flawed: lid must be removed to pour, the opening can let insects in, and the handle placement is awkward, sometimes causing spills.
- It takes around 4-5 hours to distill one gallon, which might be slow for some users needing frequent or large volumes.
- The machine and pitcher are made of glass, so they're fragile and require careful handling to avoid breakage.
- The distiller can heat up the surrounding area noticeably during operation, which could be a concern in small spaces or warm climates.
- Frequent or multiple daily uses may shorten the machine’s lifespan, so a backup may be wise for heavy users.
- Stopping the distillation cycle early is recommended to prevent heavy scale buildup, adding an extra maintenance step.

## Bottom Line

The Waterwise 4000 water distiller is a solid choice if you're serious about high-quality distilled water that tastes great and supports health improvements. Its durable build and effective purification make it a cost-saving alternative to bottled water, especially for those using humidifiers or CPAP machines. However, if you need quicker results or a more user-friendly pitcher, be prepared for some trade-offs in convenience and ease of use. For a similar distiller without the pitcher design drawbacks, you might want to explore other models or consider additional glass pitchers designed to pour more cleanly.
