A: The water is purified through the purifying candle in the following way: firstly it is forced through the fine porous ceramic wall which “sieves” out solid impurities and bacteria and then it passes over a bed of activated charcoal inside the candle which soaks up chemical impurities e.g. Chlorine. The inside surface of the candle is coated in a thin layer of silver to act as a safeguard against any possibility of bacteria build up.
A: This depends on the quantity and quality of the water going through the water purifier. The greater the degree of contamination and water usage, the candle’s life span decreases. In metropolitan areas the candles typically last between 3 and 6 months.
A: Purifying candles should be replaced when a noticeable chemical returns to the purified water. This will happen when the charcoal inside becomes totally saturated. The candle does not need replacing just because it is working more slowly.
A: When the water flow from the candle slows noticeably this is an indication the candle should be cleaned. Solid contaminates in the water are blocking the fine pores on the surface of the ceramic candle and must be cleaned off. The candle should be cleaned by removing from the purifier, running under cold water and being “scrubbed” quite vigorously with a stiff brush or scouring cloth or use the back of a butter knife to scrape off a layer of the ceramic.
A: Because the candle is blocked with impurities and needs cleaning.
A: Stefani water purifiers have been extensively tested in Australia, UK and USA to validate their performance. The terracotta is natural and the paint on the terracotta units is water based containing no lead or cadmium.
A: The purifying candles and terracotta bowls are made in Brazil.
A: No. The water purifiers will not remove any dissolved salts such as fluoride, calcium, magnesium etc.
A: The flow is around one litre per hour per candle but can vary depending on the amount of impurities. (i.e. The 4.5 litre model should be filled in around 4-6 hours, the 6 and 10 litre in around 3 hours.)
4.5 litre = single
6.0 litre = couple/small family
10 litre = large family
A: Extensive test results show that they do. Experience shows that they do. They are sold all around the world, including areas in which cholera is present. They have been sold for 35 years.
A: All our water purifiers are unconditionally guaranteed for 12 months against faulty workmanship. Candles are guaranteed for 3 months – even though they should have a life of 6+ months. The guarantee is only against faults in manufacture with proof of purchase.
A: The replacement candles are available where you bought the original unit as well as many other outlets.
A: The terracotta is very dry and dusty when it is new and gives off a slight taste. This will last for up to 3-4 weeks but always disappears. To remove the clay taste soak the unit (without the candle) in mix of apple cider vinegar and water. Soak the unit for at 2-3 hours and then give it a thorough rinse with water. Let the unit air dry in a well circulated area.
A: Not if it is maintained properly. The purifier is always slightly cool and damped. Minerals in the water (especially calcium) can be precipitated on the outside surface of the purifier during the evaporative process. These salts can build up and form a good host for dust and dirt in the atmosphere. Naturally mildew can grow in such a situation. The water purifier should be treated as a normal household appliance and wiped down every couple of days with a damp cloth. This prevents mineral salts from building up.
A: If you have recently changed your filter for our undercounter system, the cloudiness in the water is pressurised air. This is not harmful and the cloudiness will disappear over time from a few minutes up to a few days.
A: We have a selection of filters available and compatible filters to your systems will be advised at the back of your manual included in your kit. If you need assistance in regarding the order filters are installed or further information please email or call our staff who can further assit you.
A: Please ensure that you are using the wrench/spanner to assit in opening the canister by turning tool clockwise to open. You can disconnect the body to bring out of the cabinet to provide more room to work with. If you are still experiencing difficulty please contact our office.
A: Once order has been received, we will aim to dispatch it within the next two business days. You can email or contact us to confirm if you order has been dispatched and request for tracking details.
