Melody II water Ionizer-Countertop
Best quality of the Ionizer water machine.
Flawlessly provided high pH water for year
I have owned the Alka Viva Memory 2 water ionizer for 7 years used daily for drinking high Ph water in the morning and purified water to make tea or coffee throughout the day. The high Ph water has had a very positive effect on every organ and muscle in my body including hearing and eyesight remaining constant and even improving with age! I really like that I can see and adjust the actual Ph rating by adjusting the flow when filling a glass. This was unavailable on another brand I had earlier so I was never really sure of the actual Ph rating. The unit has worked flawlessly for all these years.
Great Unit
We purchased this unit to replace a 16 year old model and we could not be happier, This is the best tasting water I have ever had and both my wife and I feel like it has given us much more energy.
It was easy to install
It was easy to install and David my sales representative really gave me patient guidance and assistance in understanding points I wasn't clear on.
I embrace my new melody
I embrace my new melody H2O Ionizer like the one I had for 12+ years. The only thing I’m missing is the music when I turn on the alkaline part of the machine. My former ionizer had the music feature for the OH+ According to the late Japanese water scientist and researcher, Emoto , when the right music is played and accompanied with the water, the water crystals turn hexagonal at a faster pace and thus reaching the brain for hydration purposes more effectively and rapidly. My new alkalizer is missing this feature. I guess I’ll just have to play Coltrane’s version of “ These are a few of my Favorite Things when I use the alkaline portion . Sincerely, Linda Johnson

Everyone, today I'm gonna be sharing with you a video. So this is actually my melody too. I love it. Now, what makes this so convenient is that I can have it here in the bottom of my island, as you can see. And up there is the faucet for the water. Now, the Melody 2 is phenomenal because it actually has alkaline water. And one glass of alkaline water equals eight glasses of regular water and oxygen. It makes you feel amazing, energized. The water is phenomenal. The. The quality. Before, I used to have to buy, like, alkaline water bottles, and it was just a lot of dragging back and forth. This. This machine is the most convenient machine ever. It is phenomenal. It actually, as a woman, alkaline water helps me balance, helps me with hormones, helps me with my digestion, helps me in every area of my life and my health. I highly, highly recommend it. I did a lot of research before, so I love this. It is the most amazing machine. And yeah, I just wanted to say how much I love it. Thank you. Bye.

Hi. I just wanted to tell you a little bit about drinking alkaline water. This is the Alkavia Viva Melody and it is my second alkaline water machine. It serves both to filter water and to separate it into alkaline and acidic water. I find that it, it's really good to drink a lot of water obviously but our body, when it becomes acidic, you know, it causes a lot of problems. And so drinking alkaline water can help neutralize some of the acidity that just naturally occurs in our body. And it's incorporated into my daily routine. I drink it a half liter of water when I get up and I drink it throughout the day. I use it on its high setting also for cooking rice or for other cooking. Obviously like once you heat up water like it de alkalinizes but it's still filtered through like a two stage filter. And I just feel really great about that. I'm in New York so we have great water in the city. It all comes from an upstate like filtered naturally through the aquifers. But that extra filtering just gives me that much more assurance. I've got this through Amazon so it's super easy to find and I'm super happy with it. I've had it for a while now and I couldn't recommend it more highly if you're interested in, in learning about it. I think it beats the heck out of buying bottled alkaline water where you don't really sure like what the provenance is and it's expensive. This allows you to incorporate it into your routine and just, you know, use it like you would other water and just give you long term, you know, sort of peace of mind. So that's it and you know, hope you give it a try.

Hi, I'm Adam. This is a review for the Alkaviva Melody 2 ionizer water filter hydrogen maker machine and I've had it for over three years. It produces wonderfully pure and delicious life giving water. It works like it's supposed to. I haven't had any issues with it. The filters are just amazing. The water is better than any other water that I've tried. Let's see, I've had water filters from alkaviva for over 15 years and this is the best one of their products that I've used and I'm actually just really happy every time I drink the water and I think more people should own these and they're amazing.
