Bought for £23 and it came with a filter.
It's using by far the fastest filter available on the marketplace - so it's worth waiting those extra seconds for the water to filter through.
Of course, it can be used to filter then drink cold water too.
I can't see why anyone can complain that you have to wait for the water to filter, considering it's much quicker than the brita filters of old.
This kettle will continue to boil while filtering.
Both my wife and I find that:
1) It locates onto the base easily
2) Filters and boils fast
3) We noticed the difference it made in the hard water area of London that we live in.
4) It's ever so slightly top heavy when not fully full, but not annoyingly so.
5) It pours fast, accurately and well, so be careful not to tip it up too quickly
Overall, it looks the part even if it doesn't have a stainless steel finish and does the job extremely well of giving you filtered hot water in reasonable quantity and in a short time too.
Highly recommended
