I'd written before about the
Berkey filters and
subsequent problems. After a bit more reading, I found out that the Super Stearasyl filters that
New Millennium Concepts sells are actually not made by them. The manufacturer is
Doulton in the UK, which is a different entity. Further, Katadyn also makes a gravity-based filter, although the housing is plastic. I read on an
Amazon review that it's possible to use the
Katadyn filters in a Berkey housing, although one has to purchase a parts kit from Katadyn since the filters don't actually come with the washer and nut.
Incidentally, the same reviewer on Amazon posted a
scathing review of the Berkey filters that echoed my initial concerns. I don't regret having tried the Berkey filters, but NMC hasn't done themselves any favors with their handling of their defective filter elements. So I'm certainly looking at switching to the
Super Stearasyl filters, or perhaps the Katadyn ones. I may also need one of the
Katadyn Pocket filters as a backup.
Edit [2012.01.19]: NMC is
BBB Accredited, apparently, with only 4 claims made and resolved. Their actual address according to the BBB site is: 1023 S Main St Suite 204, Grapevine TX 76051.
Edit [2012.01.20]:
FICL (Fairey Industrial Ceramics Ltd), owner of the Doulton and British Berkefeld trademarks, has a separate website. They also
note that they don't own the Berkey brand, but do manufacture the Super Sterasyl filters.
