      REFRESHING FLAVOR Tastes great, really bubbly, CO2 last for ages. I can’t believe I used to use a countertop soda maker

      SOOO CONVENIENT! No more lugging around heavy soda bottles. If you drink a lot of soda water SeltzaTap is a lifestyle changer

      Less clutter

      More countertop space

      You’ve tried other soda-makers, but they can take up a lot of valuable counter-top space. With seltzer coming straight from your SeltzaTap and the SeltzaHub cooler box and O2 canister neatly tucked away below the counter top, there’s less clutter in your kitchen.

      This is the one you want

      My seltzer life has evolved through the phases of:
      1) Buying too many plastic bottles at supermarkets
      2) Buying a Sodastream
      3) Buying a 3rd party kit to attach a CO2 tank to the Sodastream
      4) Getting fed up with constantly refilling bottles, and that sound!
      5) Finding SeltzaHub and SeltzaTap
      6) Installing them myself
      7) Getting fantastic support from Donovan!
      8) The joy of plumbed in seltzer!

      I recommend a 10 pound CO2 tank. It's only a bit taller than a 5 pound tank (it's mostly wider), so still fits under my sink. It costs me $30 to refill a 5 pound tank and $38 to refill a 10 pound tank (half as frequently). I bought the bigger tank in December, and drink 2-3 glasses a day of seltzer. I still haven't had to refill the tank yet 4 months later.

      An error code show up rarely. But, just power cycle the SeltzaHub and all is well.

      Great product

      I did a ton of market research to find a product that'd fit our needs, which were these:
      1. could work with SodaStream canisters
      2. Looked good
      3. Made good, fizzy water (other vendors the "seltzer" is really flat
      4. Works well as a kitchen sink for people who cook a lot

      I wish I had added a fifth column, which would have been "how good is the customer service". I add the fifth one because we had some issues that came up and Donovan, the owner/inventor could not have been easier to work with, faster to respond, more generous or more gracious.

      In short, we went with this product and are delighted. The other products we saw on the market were more expensive, or required us to drill holes in our under-sink cabinet b/c the product generated so much excess heat, or it was suggested that we pay a yearly $300 "service fee" for in-person checkups. When we tested the products out and were unimpressed, the saleswoman said "oh, were you expecting really fizzy water? this is more subtle than that". As if being flat were a feature, not a bug. Insane.

      This product is small, easy to set up, does exactly what we need, and has great customer support.

      One thing that we noted was the there is an error code that comes up fairly frequently that required me to turn the machine off for a minute and then turn it back on to reset. We solved this problem by putting a vacation timer on the outlet so the machine turns off for 15 minutes every night at 3am. That totally solved the issue.

      Also just really happy to support a very smart and dedicated inventor and small business owner!

      Great Product!

      The only change I'd recommend is having a way to adjust the flow without having to take off the cover. If there was a nob to adjust it would of been nice.


      The SeltzaHub is incredibly designed with high quality materials and works just as described! Paired with the SeltzaHub Faucet, it is our favorite feature in the kitchen!


      This faucet is beautiful and paired with the SeltzaHub has become one of the favorite features of our house. Sparkling water on tap is the talk of our dinner parties.
