Culligan ZeroWater 1.7L Water Filter Jug Combo-3x5 Stage Filters+TDS meter, IAPMO Certified to reduce PFOA/PFOS, Fluoride, Lead & other heavy metals, BPA Free

In terms of the important aspect, which is filtering, it does the job really well. I can smell the chlorine in the tap water, but the filtered water has zero smell or taste. Unfiltered tap water left in a jug in open air gets a bad taste very fast, whereas the water coming out of this filter does not gain any taste even when left overnight.In terms of the 0 TDS, the filter really produces water with 0 dissolved salts (and potentially other particulates, but quantifying those is not possible with in-house equipment). In terms of health benefits, the water with 0 TDS lacks minerals and, in my opinion, is not really healthy long term unless the diet provides supplementary minerals. Unfortunately, that is the problem with a high efficiency filter that filters contaminants such as Lead or Chromium, it also filters the useful Magnesium and Potassium from the water. But with Magnesium and Potassium supplements that should be no problem and, in my opinion, that is a good compromise for reducing the heavy metals and Chlorine from the waterIn terms of the water PH, ideally, we should all drink mild alkaline water (PH>7), however, I measured the tap water to have a PH ~ 6.5., which is rather acidic and not very good for health at all. Fortunately, the filter does not further decrease the water PH by removing the salts from it, which was my main worry before I decided to buy it.The pitcher is terrible though. The lid does not close easily and the whole top bit wobbles and I worry one day when I am tired I will spill all the water on the floor. Brita's pitchers are much better designed in terms of assembly, but you do not buy this filter for that, but for its potential for filtering, which Brita is not good at.Overall, I would say the filter is great, but if you buy it for staying healthy and filtering the nasty stuff from the water, you should do a bit of research on how to supplement the minerals that are lost due to filtration. If you just care about the taste of the water, then the filter is great.

My thoughts after 1 week of use:- The pitcher is functional and well-built. Just make sure you let all the water pass through the filter before pouring it out into another jug which you can then store into the fridge.- The 1.7l pitcher fits in the door of a regular (i.e. small) British fridge.- The filtered water tastes a bit "flat" and "heavy" (no strong taste, rather a "sensation") - definitely not "better" than tap water. Add a few drops of a concentrate to remineralise it and experience a day-to-night change. Remineralised filtered water tastes as good as your best spring water imho.Overall I'm happy with our purchase. No comments yet on the filter lifetime. Our tap water in North London shows 290-300 ppm using the bundled test unit, definitely on the hard side of the scale.

Excellent result. I tested tap, bottled and spring water... Bottled was the absolute worst. Spring and tap the same amount of contaminationAll go to zero after filter. Cheapest and best way to get clean water

I wish there were separate valuations for different aspects.The filter that comes with this jug is absolutely brilliant, quite likely the best on the market. The jug comes with an instrument to evaluate the residuals (e.g. chlorine) in your water. My tap water comes with a value of 38, and my previous filtering jug was only able to lower it to about 34. Consider that a recommended value is under 6. Now, this jug brought it down straight to 0, and you can really taste the difference. The water is clear and tasteless. In addition, the filters do not come with an expiration date, but you regularly have to check the residuals they let pass; when the value reaches about 5 or 6, it is time to change the filter. I have been using it for some months and the filter is still good, so I can say the last for a lot.On the other hand, the jug itself is quite a bad product. The water reserve is quite small compared to the pitcher, so you have to recharge it often; the lid is quite flimsy so, if the reserve contains even a small amount of water, you'd better not move it or try to pour any water because it will come off; you can either pour water from the regular corner of the jug, but the opening is quite large and the flow of water is abundant and unpredictable (I always end up pouring more water outside of the bottle than inside of it), or you can use a low spout, which is definitely safer, but has a scarce water flow and requires your jug to be on the very edge of a table or something similar.All in all, I recommend the brand of filters, but possibly you should prefer another model of the jug.
