Osmio Water Reviews 

.osmio water bottles are the best

Osmio Zero 2.0 worked fine for 1 year, out of their 3 year warranty period. Now it just floods the room. They are refusing point blank to honour their warranty, insisting I flood the place again and that is "fine"/"normal", which it is not, having not had that issue at all in the first year of ownership. Not at all robust and the warranty is dishonoured. Avoid

I’ve been using this company for over five years now and have always had a positive experience.

Over that time I’ve purchased a water filter tank, shower head, and multiple replacement filters. Everything has arrived on time, worked exactly as expected, and continued to perform well long term.

In a world of disposable products, it is refreshing to find practical items that genuinely serve everyday life and last.

I’ve recommended them to friends and family and will continue using them in the future.

Machine is great - really beutifully made and the water is massively better. Especially with the option to have warm/hot/cold water on spot its really usefull. The only thing I'd change is that if i'd order again, i'd get the the version directly connected - its faff to change the water container often (I do use lots of water).
Apart from filtration, the way its build its great - its standing in kitched like a premium furniture, its just nice to look at it and the bubbles in it (osmio Zero 3.0 hydrogen)

Really disappointed Sales team told me the products were "so easy" to install and I would not have any issues. Unfortunately, it was more complicated than that (SO MUCH MORE). Because I had taken it out of the original packaging, they have tried to charge me 20% on a purchase. Yes we are talking £315 for two outer boxes (all other packaging intact). Missold and then they are basically trying to charge through the nose to discourage return

Bought Osmio some years ago to try to make water safer to drink. Have not had any issues until today when I noticed small silver particles in the water when I was sanitising the system. I contacted Osmio immediately as I realised that the fragments were coming from around the section that dispenses water. I sent photos and wrote that I thought they were metal fragments and I was worried about safety.
I received an email back promptly (great) however the email said that it was paint not metal and that I just needed to order a new part. I have just ordered and paid for the new part but personally don’t want to be consuming paint either - am quite shocked that they think this is safe and acceptable wear and tear.

Have been dealing with them for two months now as the supplied two companies I bought products from that failed. Over the two months they have dragged their heals and sent repeated low quality failing products. As a result I have replacing the system they provided as it cannot be trusted. I would avoid using any products or in any way having to deal with this company. It has been a slow and painful disaster from start to finish.

After using the Osmio Fusion Reverse Osmosis System for six months, I feel confident sharing an honest and impartial review — and in short, this system has completely transformed our daily life.

Having spent a lifetime drinking hard tap water in the South East of England, I never knew what I was missing. The first sip from this dispenser was genuinely revelatory — smooth, clean, and almost silky. It’s no exaggeration to say it feels like a soft kiss from an angel. The taste is so pure that I now find it hard to believe I ever tolerated anything else.

The only downside? Eating out has become a bit more expensive! I simply can't stomach regular tap water anymore and always end up ordering bottled water with my meals. Once you've experienced this level of water quality, there's no going back.

If you're on the fence about investing in a reverse osmosis system, don't hesitate — the Osmio Fusion is a game-changer.

Still waiting for Royal Mail to deliver 24 hour tracked parcel after 7 days with no tracking info after claiming first attempt

I bought an RO machine with a built-in water boiler (meant to replace my kettle). Unfortunately, the boiler didn’t reach the advertised temperatures, so I contacted the company to request a refund. I was made to prove the issue myself and had to purchase a thermometer just to show the machine wasn’t performing as claimed.

The company initially approved the return, but later backtracked, claiming that because the machine had been used, I wasn’t entitled to a refund—only an exchange. Thankfully, I bought it through Klarna and have now escalated the case. Honestly, if I hadn’t used Klarna, I don’t know what I would have done.

A terrible experience overall. There are plenty of other companies offering RO filters with better service—if you’re in the same boat, I strongly recommend going with someone else.

I recently had a very negative experience with Osmio regarding one of their showerheads. The product itself developed faults within1-2 years of purchase, they dont make clear their warranty period and when I contacted customer service, I was met with dismissive and unhelpful responses.

Instead of offering a reasonable solution like a replacement for the faulty product, they suggested I purchase additional parts at my own expense. When I challenged this, they essentially threatened me with no resolution at all.

This experience, combined with the numerous other negative reviews I've read online, leads me to believe that Osmio has serious issues with both product quality and customer service. Their unprofessional approach and lack of concern for customer satisfaction are deeply concerning.

I would strongly advise against purchasing any products from Osmio. There are plenty of other companies out there that offer better quality, better service, and a genuine commitment to their customers. I suggest any consumers with issues with this company please take it up legally especially if you have sent hundreds of pounds

I bought Osmio gravity filter.In the first month the ceramic filters started to turn green- algie grew as is glass.I didn't know this at all. In 2 months the filters were dark green.It looked discusting to drink. The Osmio customer service just told me that they have discribed on their website that discolouration is possible.Did not give me new filters ,nor refund. I would not recommend. I got attracted to the glass aspect but didn't know filter would be green.Disapointed as is not cheap.

I sadly chose Osmio as the best company to buy a Hydrogen water bottle from. What a mistake. After spending £180 for the newest model it arrived and was defective. I called the 'customer service' for help and advice - was met with a rude person who couldn't' wait to get off the phone. She insisted I take a video of my thumb on the start button with nothing happening. I did as I was bid..... eventually I received a reluctant agreement this unit was defective. They sent a label for return........ later that day I received an email saying that was the wrong label......the next day I received another email saying wrong label again.
I am waiting for Royal Mail to pick up the return........ and have asked for a full refund. Hopefully this will be given without further ado....... ?? Will update this review about that.

Having had an osmio for about 3 years I came to change the new filters, one of them is what I would call faulty as it won't go into the machine like the ones I have used before. I messaged osmio and was told to watch a video (I've been using these filters for 3 yrs!) and try again, I can see the problem is too large a head on the filter but they want a video of me putting the filter in. How do you video and put a filter in that takes two hands! Totally disappointed since I have offered to return the faulty filter for a new one.

I can only speak as I find and I have only ever had really good experiences with this company.
Ordered some new filters on line and arrived next day.
A really good RO system.

I’ve had the worst experience with Osmio Water and strongly advise everyone to stay away from this cowboy business. They repackaged a used item and sold it as brand new! It was clear that the product had been tampered with, but they had the nerve to pretend it was new.
Their customer service is nonexistent. They expect you to cover the cost of returns yourself. When I tried to return the faulty machine, they not only made the process extremely difficult by requiring me to follow10 silly steps, but they also had the audacity to charge me for a set of filters that they asked me to return. I’m sure that machine with its set of filters have been traveled through many households and will continue to do so if you ignore this warning.
This company is a total scam—save yourself the trouble and avoid them at all costs!

At first it was all good. Despite not being provided a plug and there being no charge cut off, I followed all the rules to the letter. Then from nowhere the red button of beeping death and the product stopped working.

Not to worry, thinks I, I’ve paid top dollar for a quality item so support will be great. Not so much. Every excuse blaming me and not the product. What charger do I use? Please send a picture? From a generic plug to usb charger they determined it is the wrong one. I can buy a new battery apparently. Absolute rubbish. So disappointed as the bottles cost a fortune.

If I were you I’d go elsewhere where you can get the same quality for less and, to be frank, the support can only be better than I have experienced.

Bought for my dental surgery. Cartridge needed replacing every month. Previous machine lasted 10-14 months before needing a change. Incoming water at 300ppm and using about 5L water per day

Bought a whole house water filter from osmio water 1 year ago with one ceramic and one carbon filter and it works very well. The housing is a quality brand (from Italy I believe) and we don't have any chlorine taste or smell anymore. I can't comment on other impurities because I have not tested for this. It was easy to contact osmio waters by phone before my purchase, and I was given a long talk about my options regarding different filter systems. The price is very good. I would recommend.

After several years of using the Osmio Zero 2.0 Reverse Osmosis System (Black), which I consider the best money spent, something had broken. The Osmio Consumer Services provided me with all the necessary information on how I can repair it myself and even offered a home service.
I chose the option of repairing it myself, the video instructions were so understandable that I managed it without any problems.
I am not an engineer by education; I am just a middle-aged woman looking for savings and would like to contribute to environmental protection. I replaced the pump supplied by Osmio myself, which I am very pleased with and only cost me £60.
The Osmio company made a great impression on me. I wish there were more such companies. Five stars from me and I must admit that I am quite picky in my ratings.
Thank you for a great product and excellent service Osmio ;)
Kind regards
