The wrong water distiller can waste your time distilling water, and it can break down. If you own a medical facility or a dentist's office, you need a distiller, so your patients can rinse. The right water distiller distils large volumes of water, so it meets your personal or professional needs. Choosing a water distiller might seem difficult because manufacturers market so many options. Follow a few guidelines, however, and select a water distiller that fits your needs.
Match your preferences to the distiller's distil rate. Select either a manual distiller or an automatic distiller. Manual distillers distil 1 gallon of water at a time while automatic distillers distil continuously because they hook to your home's incoming water line.
Match your water consumption needs to the distiller's holding capacity, knowing manual distillers can hold up to one gallon of water while automatic distillers can store 10 to 25 gallons of distilled water. The holding capacity differs from the distil rate because it represents the amount of distilled water a distiller can store for later use.
Compare construction, and look for food-grade stainless steel or a stainless-steel boiler.
Compare dispenser material, and look for food-grade stainless steel or "non-leaching" plastic. The dispenser consists of the nozzle that dispenses the water. Food-grade stainless steel ensures your water remains pure, and "non-leaching" plastic consists of plastic that will not pass chemicals into your water.
Compare prices. Manual distillers cost £12 to £57. Automatic distillers cost £38 to £194.
