“I purchased an Osmio Zero last year. Almost immediately I noticed that water coming from the filter was good tasting sometimes and other times tasted like bad rubber hose. After much experimentation, I have found that the bad taste comes after filtered water has been sitting in the machine for an hour or more. The first approximately 130ml coming from the Zero tastes like rubber hose. The subsequent water, if one immediately draws on the Zero, tastes good. I discussed these issues with people at Osmio, who tried to be helpful, and they made some suggestions. Like the bad taste might come from the mineral cartridge. We tested this with an empty cartridge and found it did not change anything. My guess is that somewhere in the distal part of the Zero, a volume of filtered water is in a tube that imparts a strong rubber taste over time. Once 130ml of water has flushed this out, the subsequent water is fine as long as one doesn't wait too long to dispense the water. After an hour of sitting the bad taste builds up again. I continue to use the Osmio Zero but it requires flushing 130ml out every time I want water. In practice, I dispense 130ml and discard it. I then dispense 1L. This works but it still wastes time, energy and water. Osmio should figure this out and eliminate the bad tasting tubing. Just to be clear, I also sanitised the unit using the instructions and gear from Osmio and this had no effect on the bad taste. I also sent back the Zero to Osmio and had them drill a hole in the side to drain the effluent down the sink rather than back into the water reservoir. This also made no difference. The unit has been restored to function as designed.”

“Osmio 3-way tap is a well designed, solid tap and fairly easy to install. The only issue I had were two adaptors missing in the package. I had specified the connections we have in our kitchen and hoped adaptors for would be included.”

“I purchased an Osmio EZFITPR-O300 and have juts installed it. It took a while to arrange the recommended bypass pipework and valving. Also the filters only just fit in the cabinet under my sink height wise, allowing for filter replacement and to get a screwdriver in at the top for air bleeding (I have a Belfast sink unit). Installation instructions (once found) on-line easy to follow. It would be good to include these with the product. These instructions don't fully align with wording supplied with filters or what is said on YouTube channel. It would be good to get everything aligned. I also think it would be easy to get filters in the wrong way round, so some clearer marking on that would be helpful. Finally I would say something about recommended clearance above and below the unit before installing (for screwdriver and filter replacement). Overall I'm very pleased with the product so far. The flow rate looks acceptable and the water tastes nice and clean.”

“The replacement cartridges arrived well packed and ready to fit, I am unable to loosen the fitting to replace them though. I had hoped to ask for local help otherwise I am going to have to get the plumber back. Am I able to ease the case in any way please.”
