The Delphi H2 Undersink Water ionizer is now available with a payplan. See our payplans page for details about how our payplans work. To order your Delphi H2 water ionizer first pay for the downpayment with this link. Then wait till we send you a document to e-sign. Once that is done, we set your payments up for 10 months of equal payments to cover the balance due.
