The siphon filter is a ceramic candle-type water filter for household use.
It uses gravity pressure to force water through a high-quality ceramic
filter element impregnated with silver. The product is very compact,
consisting of only a filter element, a plastic hose, and a valve. Some kits
come with 2 water containers, or households can use existing
containers. The siphon action (flow) is started by squeezing the bulb,
and then the water flows by itself.
Produced and imported by Basic Water Needs India Pvt Ltd. Filter
element cannot usually be produced locally. Currently implemented
around the globe by EnterpriseWorks/VITA and Connect International.
Ceremic element is quite
fragile; plastic parts are robust.
A washable fabric layer strains
large particles to reduce
clogging of the ceramic
element, but the element may
clog if inlet water contains fine
silt. Ceramic filter element
needs to be replaced if there
are cracks or leaks. Use out of
direct sunlight to avoid
degradation of plastic parts.
Lifespan:
Can treat up to 7,000 litres,
depending on the turbidity of
the water. At 20 L/household
per day, this will last just under 1
year. Plastic parts will last 5 years.
