Still haven’t tried the coffee. But being biodynamic I am sure the taste will be great. Just hope it will be mellow.
I can’t believe the results of the shower head!! Removing the chlorine out of the water has made my hair and skin so soft! The shower is also more powerful. I highly recommend and my kids love it too!
Amazing! Thank you!
Absolutely love this shower head, brilliant water pressure the added vitamin c leaves your skin and hair feeling very soft and fresh.
Would highly recommend even my hairdresser has commented on my hair, can’t imagine not having it now . thank you Hydrowerks for a fantastic product.
Osmio infinity arrived June 1st 2023. Richard was extremely helpful.
Immediate improvement was drop in weight (fluid retention), reduced lymph glands and reduced antihistamine use for mast cell activation disorder. Daughter has T1 and noticeable improvement in blood sugars (genetic mast cell condition that can spike sugars). Throughou, Richard has been fab, very approachable and supportive.
A friend is using our infintiy this week (very good friend as we haven't loaned it before) for poor healing on a leg rash. They are finding improvement after a few hours use. We are really missing not being able to use it while it is on loan which feels like a good experiment to keep us focused when it is returned. Ikea three tier trolley makes it easy to make the most of using it.
We love our new shower the water pressure is great, we love the lox tox benefits.
I have been using this machine to help with my migraines fir past fews years now.
I was getting 1 migraine a week! Which would last for days! After using the infinity machine the migraines have reduced considerably i get the occasional one but after using the machine they subside. At one stage i went 6 months without a migraine which was amazing.
I highly recommend this machine its worth every penny. I use it for other aches and pain and also helps me sleep better when i use it at night.
Richard from hydowerks has been a fantastic support. Always happy to answer questions and help in any way he can. He is very passionate about helping people get better. Thank you Richard
After moving to a narrowboat 6 months ago I had been buying spring water at £1.50 for 5 L, approximately 6 bottles per week , I won't drink tapwater although free to a boater , and a 700ltr tank on the boat is good storage ,but could only use it for washing and toilet, after a visit to Richard @Hydrowerks , i now I need no extra storage for bottles , no kettle , and have no extra water bill of £10 pw, clean safe water instantly , absolute game changer for a boater .......👌🏼
A gentle and relaxing shower head with Vitamin C. Simple, transparent design. Was hoping it would help with hair loss but too soon to tell.
Hydrowerks ships promptly and is a good company to do business with. Thank you!
We’ve had our water filter over a month now & absolutely love it. Not only do we get filtered water that has no taste so ideal the 4 choices of temperature are fab. We love the fact we’ve been able to put the kettle away & at the touch of the dial we have 4 options. I often have the 65 degree hot water as it’s drinkable immediately, worth every penny, we’ve told so many people of our great find!!
We use this for my Autistic son and it’s so much better and calming and refreshing for him over the normal shower heads. Would recommend
On the advice from Richard at hydrowerks I purchased the osmio infinity to help with arthritis in my hands. After using the infinity over night for a week the difference in my hands was amazing, almost no pain at all and swelling of the joints reduced down to practically nothing, really impressed with my purchase and use it daily…..when I can get my wife off it.
Very happy with the service, good communication, thorough work and quick turnaround.
Cool design and no chlorine taste or smell so it does what it's supposed to do! My wife bought one of the cheap Chinese ones and it smells and tastes of chlorine I told her to stop using it and order one of these H2xagen bottles
Tangible results whilst relaxing and breathing ! Pain from ankle gone, anxiety decreased in one 20 minute session. Bonkers!
A dose of vitamin C during a shower is a unique experience. The skin is softer and more delicate and the hair is smooth and easier to comb. Truly recommended!!!
