Question: does the time-life electronic indicator have a replaceable battery
Document: I have replaced this system twice. The built-in electronic filter life indicator stopped working on both systems after two months. I did not have any problems with the old design, but this new design is junk.
We've been using PUR's 3-Stage Faucet for 1 1/2 years now and it's been under Very heavy use. So far, everything still works perfectly and I couldn't be happier. On average, a filter lasts about 2 months and the water tastes pure.I have to say though, it does have two drawbacks that I've found.The "Built-in Electronic Filter Life Indicator" I don't believe works correctly.
If it becomes a full on leak, I will try the second connector that was sent to me. The new problem though this time is that the indicator light is no longer working. I read in some of these reviews that it is run on a battery that can't be replaced.
I am pleasantly surprised this time by the new model with a completely new design. I ordered one to replace my old filter unit, as the old one (a year old) started to leak.The filter housing is fixed at an upright position (no rotation), and the switch is placed on the right side of the unit - like more expensive PUR faucet filter models. The new model has an electronic water quality indicator that has replaced the old clear slot window.
This unit has a LED-based filter-life indicator which, with my relatively low use rate, seems to have a time-based mode in addition to a presumed flow-based mode (all previous units I owned were strictly flow based). It appears there is no positive cut-off for the flow-based end-of-life as was incorporated in my previous units, so I am assuming the LED is the only indicator.
However, when it arrived, it was not the original vertical mount filter shown in the photo, it is the new model with the easy-mount system. The product description on the website does not mention either the new attachment feature or the electronic indicator light, so I believed it was the other model.
I have owned several of these PUR water filters, but recently needed a new one (the old one was leaking). I purchased a new version of the same thing at a local store, though it now has an electronic indicator to show when the filter needs changing and a new, easy mounting system. That model has very shallow, plastic threads and does not fit my faucet so that it easily falls off.
They units typically last about a year, then the battery indicator light no longer flashes. The filters for our house of 3 are easy to find online {Amazon} and in stores [Costco, Walmart, Target]. For our house of 3, the filters last about 3 months. We haven't had the problems that some of the other reviewers indicate--cracking, leaking etc. These units have been very reliable for us, and much much cheaper than an installed filter or water delivery.
No more plastic water bottles clogging up our garbage bins.The Cons:Seems like it is poorly made-plastic and possibly easy to break. (It looks much more matte plasticy than the metal look in the photo). No battery compartment (I think) therefore the led light that lights up when water is filtering may go out and the entire unit may need to be replaced. I would recommend some other type of indicator, or none at all.
I see other good reviews, so I may just be one of the unlucky buyers. It was great until the indicator said I was about 1/2 way through the filter life.
Answer: yes
