The current U1-W 1-year bundle is $129.99 and excludes the RO membrane. The 2-year bundle is $338.32 and includes two annual filter kits, two hydrogen modules and one RO membrane.
1-year bundle
RKIN currently lists the U1-W 1-year bundle at $129.99. It includes RC-QT-PAC, RC-QT-CF and RC-HGPEM, but not the RO membrane.
2-year bundle
The current 2-year bundle is $338.32 and includes two annual replacement kits, two hydrogen PEM modules and one RC-QT-RO membrane.
Savings vs individual current prices
The three one-year components currently total $144.99 individually, so the $129.99 bundle saves about $15. The 2-year component total is listed by RKIN at $372.97 versus the $338.32 bundle, a saving of about $34.65.
Which bundle fits which owner
The one-year bundle is simpler if the RO membrane is still healthy. The two-year bundle fits owners who want to pre-buy the membrane and two annual service cycles at once.
