Title: Is it a gimmick or does it actually work...
Review: I have well water and very hard water. I have two whole house filters, one to catch sand and such and another that is a charcoal filter then through a rust reducer water softener. All together it has reduced the hard water to about half of what it had been down to around 250 hardness.This has a display that shows input and output total dissolved solids (water hardness) but does that display actually TDH? I decided to see if it does. One of the things that had me wondering was the output had always showed 25, never changed. Real or faked? The input does change but has always showed about 250 or higher and increases as it dispenses water.First how this water filter works. Basically a reverse osmosis filter is a filter that the pore size is the size of a water molecule... anything bigger will not pass through but anything the size of a water molecule or smaller will pass through the filter. Using high pressure the water is pumped through the filter forcing water molecules through the filter. Any water that hasn't gone through the filter to be dispensed is "waste" water. This water is pumped back into the tank and as "pure" water is removed the concentration of "bad" water in the tank increases. So yes the input side hardness number should increase. This "bad" water is pumped through the filter several times which does decrease the total amount of water that will be waste water. It also increases the total dissolved solids in the tank water which the input number shows as increasing. It's also why the tank needs to be dumped and filled instead of just adding water to it without removing the tank.But that output side hardness number always showing as 25 still had me wondering.I have a water distiller so decided to use distilled water to fill the tank instead of filtered tap water, after two or three tanks of using distilled water the output hardness number started going down and then stayed as 8. It would take more then using a single tank of distilled water to show a change since there is an internal tank that would need have the "old" water flushed out of it.Not having scientific instruments to actually test the water the best I can do is make some observations. Distilled water uses heat to create steam that is cooled back into liquid water, anything that evaporates at or below the temperature that water evaporates at would also be distilled. Alcohol for example. So depending on what was in the tap water distilled water may not be only H20.Stokk E1 also has more then just the reverse osmosis filter. First there is a PPC Filter that "Removes Odor, Reduces Chlorine, Reduces VOCs, Reduces Sediment", then the reverse osmosis filter followed by a C Filter... Post reverse osmosis filter coconut shell Carbon Filter. This carbon filter "Improves taste by adsorbing off-flavors and odors in the water". To me this indicates it's for absorbing anything same size or smaller then a water molecule. OK so the output water hardness will never be zero.Back to the question of does the display actually indicates input and output total dissolved solids. From what I have tried I would say it does.I don't know how accurate it is but I would say the output TDS has to be pretty darn close with all the filtering my tap water goes through and then distilled and then put through the reverse osmosis then through a final carbon filter. If it shows tap water that starts out as 250 TDS outputs as 25 TDS and the distilled water shows output as 8 TDS it is measuring TDS and not just showing a fake display. I don't expect the display to be lab quality accuracy but it does show that the machine is actually doing something.Personally I consider a reverse osmosis filter as the best water filter and have for a long time wanted one but always thought dumping as much or more water as waste water then it produced as very wasteful. It's why I went with a counter top water distiller. This reverse osmosis filter recycles the water several times reducing the amount of water lost as waste water.When compared to my counter top water distiller the distilled water may be better with lower TDS... maybe... but it takes about 6 hours to produce a single gallon of water. RO water is also a good quality water and is much quicker to make. Anything larger then a water molecule should be filtered out with RO so water hardness should be on par as with distilled water. I'll likely put my water distiller into retirement and even use the water from the RO for my coffee makers.I would buy this again.

Title: Adequate
Review: Got this as a temporary replacement for an under-counter system while we're out of our house for repairs. I'd like to see some of the removal numbers/percentages even closer to 100%, but it's definitely a major improvement over the tap water. The pre- and post-removal TDS are around 150 and 5. Not sure whether the post-removal number has to do with remineralization.It's easy to use.

Title: Filters out 99% chlorine AND FLOURIDE!
Review: I did a fair amount of comparing filters. I’m in an apartment, so I didn’t want to commit to an installation. Also, finding a water filter with the statistics of this Stokk E1 was difficult for my budget! It was on sale during Prime Day, so I pounced on it. Also, one doesn’t have to change filters for a year!! The filters are reasonably priced too. It doesn’t take too long to fill up the included GLASS pitcher and the reserve tank is large enough, so I don’t have to fill it every day. It’s not too big on the countertop, either. It’s “early days,” but so far so good!

Title: Stokk E1 Reverse Osmosis Water Filter Countertop,
Review: This reverse osmosis water filtering system works better than I anticipated. I knew our city water was not the greatest, I did not know it was that bad until I set this up and drank my first glass of water. I did a taste test and compared a RO glass of water to a glass of tap water. The tap water is filtered with a filter directly on the faucet.My initial reaction to the RO water was okay, water is water it tastes better but I didn't feel like there was much difference. Then I drank the tap and OH BOY was it gross in comparison. I mean it was so gross that I couldn't even swallow it, I spit it right back in the cup and said no more.The true test was having my common-law mother-in-law try some. She reacted the same as I did when I simply gave her a glass of the RO to try. She said she really didn't notice much difference, she said she thought it tasted better but not enough for it to be worth the hassle, and since she knew it was RO water the better taste may have been wishful thinking.Later that night I had her do a comparison. She had no idea what type of water I was giving her. I gave her the RO and she sipped it like she does, and showed no emotion, like she does. Next I gave her the purified tap water and she spit it right back into her cup and said eww what did you do to this water it is disgusting. You should have seen the look on her face, I have never seen someone's face twist and turn with so much disgust and embarrassment as hers did when I told her I didn't do anything to the water it is the same water you drink every single day. To be honest it was pretty satisfying for me personally.It has a decent sized tank, the reservoir tank is also the waste tank so you need to empty the waste water every time you refill it with clean water. The machine keeps filtering the water through until the water becomes too saturated with particles, this water needs to be emptied.If you don't want to dump the waste water down the drain there are a few things you can still use it for. I put some in a coffee cup and put it in the microwave for 5 mins to clean the microwave. I also use the waste water to water my house plants. I am considering saving the waste water to water my garden next year. I have 2 rain barrels, I need to do a little more research first but I think this is will be a sustainable option also.The water going in straight from my tap was over 500 ppm and the filtered tap was close to 400 ppm. The water coming out was less than 50 ppm for the first few pitchers and now it is around 18 ppm. I am assuming this is because of dust inside the machine or the filters needing to be activated.I don't have anything negative to say about this machine, it does not take up any more space than a full size coffee pot.Having clean water that tastes good is priceless so this is definitely a good value.So Yes I would recommend this RO system it is easy to set up and use.
