Differences between Water Purifiers

Difference between Stainless Water Purifiers and Stoneware Water Purifiers
Stainless Steel Water Purifiers are light weight to ship and compact to pack away and travel. Stainless Water purifiers can only store up to the join and can over flow if you keep filling and not use the water in the lower tank. Stainless steel can look a bit commercial compared to the Stoneware, however less likely to be broken if dropped but may dint. Stoneware tend to keep water natural cooler.The Berkey stainless steel units have two candles standard, so filter at twice the rate. The unit can have four candles in them. Stoneware units the upper filter chamber sits inside the tank, so it can't over flow.

Difference between Ming Porcelain Water Purifiers and Ceramic Pottery Water Purifiers
Why are the Ming so cheap compare to the the other units? Chinese labour mainly and they are cast made.
The Ming are porcelain like your bathroom basin or table ware. Usually a bit stronger than ceramic however still will break if dropped on tiled floors. Other than that both Porcelain, Crystalline Porcelain, Ceramic, Terracotta and Stainless will filter your water just the same through a ceramic gravity filter candle at a rate of 1 litre per hour per candle. The Billabong, Crystalline and Artist range are Australian made and turned on a wheel with a potter, so they can vary in size slightly and color. The Crystalline glaze ones have the base connected to the tank, while the Ming, Billabong, White-Clay and Terracotta all have a separate pedestal they sit on.

Difference between Ming and Billabong compare to the Artist range of White-Clay and Terracotta Water Purifiers

The Artist range of White Clay and Terracotta are sealed external and clear glazed on the inside so they don't leak or seep water. These units externally are only glazed on the bands and the decorative glaze detail otherwise they have exposed pottery. With these units you need to keep them away from oils as they aren't easy to clean if stained. The potters who do the glaze work on these units win awards for their detail work and that's why they are expensive. 

Difference between Terracotta and Ceramic / White Clay

Apart from the appearance, for the user there is no other difference. No, the Terracotta will not go mouldy, that can happen to units that are not glazed inside (like South American(Stefani) or Mexican units). Most units in Australia are glazed inside for easy maintenance.


No units have toxic glaze inside them and all of them as safe as the mug you drink your coffee or tea from.
