I believe the Coldstream Sentry to be the best gravity water filter on the market today. I've purchased multiple units for friends and family as I'm aware of the importance of drinking toxin and chemical free pure water. I buy from Osmio because of Mark's genuine passion for what he does. James Corr

I am using Osmio Vit. C shower filter for a week now and find it really good on my skin. I have to see after more weeks to see how good it is.

Really happy with the prompt, courteous, accurate and efficient service from Osmio. I have a old style reverse osmosis water filter, and it needed all 5 filters changing ..not straight forward . My on line chat with the helpful Osmio operative sorted out all the issues, and hopefully will be easier next time. Parcel arrived the next day, and with all the correct filters.All up and running now . Very pleased . Excellent service, and would definitely recommend. Most professional.

Osmio Swan 304 SS single tap arrived promptly. The 1/4inch push-fit connector screwed to the tap was cross-threaded, probably due to the somewhat flimsy packaging ( it had been squashed in transit). However, the screw thread on the connector was undamaged and did not leak on fitting. It would have been better if it had been individually packaged in the box or a stronger box used. Am very pleased with its functioning and despite the problem, would buy from Osmio again.

I received clear advice on the difference between the two products I was considering. Very quick delivery. Installation and set up took just under 2.5 hours which as what we anticipated. I chose this RO system on the basis that it has a post filter which I understand is meant to add back calcium and magnesium (and possibly other trace elements and/or electrolytes including potassium?) but cannot obtain clear information from OsmioWater on exactly which elements and in what approximate quantities (even given temperature variations) that they may be added back to the filtered water. I also have not been able to find any information that shows that a silver impregnated activated carbon post filter would actually add anything back to the water after the previous filters. Given my concerns on this I may be disconnecting this RO filter system and looking at other options to ensure that essential elements can remain in my family’s drinking water.

parfait, mais par la suite j'ai peur de payer des frais de douane pour la France.

Having had a very quick response from the sales team answering my questions with live chat has made me feel very confident in the Osmio Zero. I've just put my order in and look forward to my family having safe water to drink with no micro plastic contaminants!

Delivery was excellent. The only reason I have given Good and not Excellent is that the cold water fitting was too large for our system and I had to purchase a T fitting and reducers. As it was only fitted a few days ago I am unable to rate the performance relating to water filtered, I will do this later when the system has been running for a while.
