      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.

      Customer Reviews

      Based on 7 reviews
      Very unsatisfied

      Both the hub and faucet were installed according to the specs and instructions. Immediately noticed that the carbonation was far less than advertised. Reached out to the owner, Donovan, via email and explained the issue and how the unit was installed per his instructions. He replied saying that he would have to think about it and we might need to talk on the phone (Red Flag when they don’t want to put their excuses in writing). I replied and explained that I was heading out of town for the holidays but asked a detailed question regarding the CO2 pressure. Over two months have gone by with no response from Donovan regarding my previous two emails. I still try to use the unit periodically, but the carbonation is weak and the hub now makes a very loud noise whenever it re-pressurizes. The noise is so loud and violent that it would be embarrassing to use with guests nearby.
      Their troubleshooting guide does mention this noise as an issue, but the only solution is to turn the unit off (wow…really?!?). I wish I had done more research and went with a more reputable company, but now I’m stuck with a $2000 paperweight!

      Blows the competition away

      We finally decided to pull the trigger on the Seltza. First off, the set up was a breeze, and Donovan was there to guide me if needed. Nothing complex and it was set up in 30-45 min. It works very well and the whole family is enjoying it every day. Before purchasing the Seltza from Donovan, we tried out the competitive German product thinking that it would be better. We were sadly very disappointed in our experience. The setup was very complex, the system ceased to function and was replaced 5 times, and it is more expensive. The German system was significantly bigger, additionally, I had to make holes in the cabinet floor to accommodate the air circulation and system feet which is not required by the Seltza. Thank goodness for the Seltza. All the benefits, none of the hassle.

      The Best!

      We've been looking for a compact and effective solution to our home carbonated water consumption "problem" for a while. I can report that the Seltza system is everything we hoped it would be: simple to set up, unlimited chilled carbonated water, and great looking! Prompt and knowledgeable support when it came time to install . . . Donovan even made a house-call to ensure that we were on the right path!

      Great product, easy to install, Donovan provides good customer support

      Bought this after comparing with Grohe Blue. Much better product and much better price. Carbonation level is better than Grohe Blue, provides really good water pressure. Donovan has provided really good customer support during installation as well. Very happy with this buy!

      A luxury, but it’s my favorite one

      TLDR: this thing is amazing! If given the option, I’d pick this again over any other product out there (and not just because there aren’t many options in NA).

      I remodeled my kitchen this year and decided that my soda stream, while way more eco-friendly than La Croix and Perrier, was inconvenient. I was constantly filling up liter bottles and half of it went flat before I could drink it. I hated replacing the CO2 every month and it was way more expensive than a large CO2 tank. I visited my company’s office in Europe and saw an on-demand soda faucet in the kitchen and knew I had to have one. I looked into Grohe Blue but it was really expensive and the reviews said it was super loud. And that’s literally the only option my contractors and many others knew about.

      Then I found Seltza Tap. The carbonator is small and fits well under the sink. It’s relatively quiet for a fridge right after refilling a glass, and it has a quiet buzz after that, which truly can’t be heard when you close the cabinet. It was really easy to install, and now I have basically limitless soda water in the exact amount that I want.

      The fizz in my experience is more than Perrier and less than La Croix. I’m not picky, but if given the choice, it’s the exact level I like. My tank is right at 75 PSI and I set the temp to 6°C. I think if you make it colder, it will be more fizzy because the CO2 integrates better with colder water.

      One special note is that I used a different faucet because I really loved the Brizo beverage faucet. The carbonator/fridge is compatible with any normal faucet than can handle high pressure.

      I’m in Seattle and shipping from BC was fast. The worst part was waiting 4 months for the remodel because it was installed on the last day of the project. Thank you so much Seltza Tap for making this in a market severely lacking options for on-demand soda water.
