This is now a 5-star review. I've purchased additional units (they have slightly changed the color, but nothing else). I didn't purchase the others because they broke, but as gifts and added resources (one in fridge, one room temp). These are in my opinion, still the best bet for the home!
Note: hesitant to give 5 stars until I've had it at least 6 months.
This is a fantastic filter. I've had a PUR pitcher filter, tons of Brita pitchers and bottles, and PUR tastes the best. The form factor is perfect for the fridge, though I wish the spout was higher and further out (it brushes against my fridge shelf sometimes, gross). The reservoir is 1 gallon, as is the capacity.
Note1: PUR and Katadyn are the same company. Campers, backpackers, mountaineers, military, special operatives, and hikers put their lives, and general health, in the trusting design of countless Katadyn filters (Hiker, Hiker Pro, Vario, Combi). PUR is their home consumer branding of products.
Note 2: Filters work with different materials, but for the same principal: to extract water with lowest particulate possible within a given timeframe. All filters eventually end up collecting the "waste" with the side effect of you tasting it as usage increases. There is no way around water touching the contaminants stores inside the filter. This is why most filters include a charcoal core, which adjusts perceived taste of the water by masking, neutralizing, and adjusting the ph of the water.
Note 3: Some filters by company's like Zero Water excel at very fine removal of all elements in the water. This is seen as a pro and con. The positive is that the water is very light and without those chemicals, the cons are numerous: valuable electrolytes are removed, filters tend to slow down faster and taste raunchy quicker, and your tap water is regulated (unlike bottled water), meaning only the basic compounds need removal. This is where this PUR filter is more appropriate. It will have a higher rate of filtration and not be overkill for a regulated water supply, such as your tap.
Note 4: The filters are advised to be replaced often, however there's a marketing reason behind it. The filter would likely not need replacing for up to 6x as long as stated. Due to the reason of waste collecting as I mentioned, the filtration slows and taste develops. One can simply remove the filter, tap it on a counter a few times, and swish it in water. Repeat a few times and you will loosen most of the deposits. This is how outdoorsmen survive with the same filter for several years without needing it replaced. In fact, bleach is usually drawn through it (if not ceramic) and dried before storage. We don't just buy a new filter if it's been a while. Remember this. There is a lot of surface area for your filter which is underutilized. You can "refresh" them on your own!
Thanks, hope my rants help!
A lot of people (well actually, almost everyone) who own the dispenser complain that the filter seems to clog up much faster than expected. Since I own both the PUR products, and they use the same filter, I feel curious about why the filter in the dispenser stops dripping water after a mere two weeks, whereas the one in the pitcher works with no problem at all for months. A close look (well, not even close) and a little physics give you the answer. For the pitcher, the lower chamber is open to outside via the funnel ("mouth") at the top, so there is no imbalance in air pressure. But for the dispenser, the lower (receiving) chamber is essentially SEALED from the outside by the upper container and the tap. When you put everything in place and pour in water to the upper chamber, water starts going through the filter by gravity. However, the water that is coming down is trying to compress the air in the receiving lower chamber. The more water filters in, theoretically the more pressurized the lower chamber becomes. But of course that never happens because the air will go BACK UP the filter to resist being compressed, since the gravity of water is such a poor force doing the compression. As a result, a little bit of air becomes trapped inside the filter, each time you pour in fresh water on top. After about two weeks, there are so many air bubbles inside the filter that they essentially clogs it up. If you hold the filter closely under a little sunlight, you can see the myriad of bubbles inside.
So right now what I do is I keep a spare filter (who doesn't?) and switch them every two weeks. Just soak the "used" clogged filter in water for 5 minutes, take it out, and gently tap on the counter top and it is good to go again! Do NOT throw those away. It is really a shame on PUR because all they have to do is alter the design of the lower chamber just a little bit, either create a small shaft to the outside or some small holes on the side so that air pressure could be instantly balanced. Well if I get really frustrated one day, I might just take my old drill and make a small hole on the side above the water level and be done with it.
I must say, the taste of the water was top notch. Best tasting water to date from a gravity filter.
However, give it 7 to 10 days, and the filtration becomes something RIDICULOUSLY SLOW.
I mean, 8 hours to filter 2.5 glasses of water slow. for only 7-10 days of use, this is not acceptable.
I tried all the things recommended by people on here. Shaking it and leaving it in cold water didn't work. Shaking it vigorously, then rinsing it, then letting it soak upright (and only upright) for 15 minutes didn't work either.
Even if it did work, after 7 - 10 days with a brand new filter, the amount of effort recommended for it to work correctly would be crazy and time consuming.
