answer
Yes
The cartridge contains a filtration medium that needs to be
kept moist to do its job effectively. The plastic wrapper
helps to retain the moisture during transit, but to ensure
the cartridge works effectively it needs to be soaked for
10 minutes before use.
Like any foodstuff, water is a perishable product. Filtering
removes chlorine, which is used to sterilise the water,
thus reducing the shelf life of the filtered water. Any unused
filtered water should be discarded after 24hours.
For hygiene reasons the cartridge should be changed every
30 days regardless of usage.
On occasions when using a new cartridge the first few litres
can appear to be tinted black/blue. This colour is due to a
small amount of carbon dust being flushed out of the
cartridge. This is not harmful as the carbon is food grade
and will usually disappear if the cartridge is flushed
through a couple of times.
The cartridge has mesh filters top and bottom, which trap
fine particles. A special food grade resin removes heavy
metals and limescale. Activated carbon removes chlorine
and some organic pollutants.
Yes
Yes, filtered water is suitable for babies and making up
baby formula. However like tap water, it must be boiled
and cooled before being given to babies and infants.
