Anywhere else around the area, my Britta would clean up the taste of bad water, but not here. Here it's SO chlorinated, I needed something better.After a lot of reading and research I was down to the Filtrete Under-the-counter unit and this unit. The Filtrete pro sounded like it had a strong flow and filtered down to .5, but after looking at it closer, it would be just my luck to have a connector pop out and cause water damage without me around. So, I decided on this.I had it connected in under 5 minutes. I just needed a pair of pliers to loosen the faucet part which needed to be removed. The unit came with a needed adapter which worked perfect. I turned it on and after letting it run for a few minutes, I tried the water. AWESOME!!! Clorine smell and taste was GONE!This thing works, and works well and I don't have to worry about broken lines under the sink. The water flow remains good through the unit as well. I can also find many options in replacement filters because of its standard size. I love the quality and functionality of this unit.THE BAD.The problem was, upon closer inspection, there was a small bead of water coming from the units water output. At the bottom of the metal output piece (Which you can just pull out) there are 2 small, round O-rings, and one was pertruding. It was cracked, so only one O-ring was ok, and when I moved the water output, it beaded up.I called the "Manufacturer", which sounds like it isn't REALLY the manufacture, but a distributor, and was told they don't have any parts, they get the unit assembled. The parts they DO carry they said, are all given to Amazon. SO.... they told me I should pack it back up, and send it back to Amazon.What?!? I am suppose to ship the whole unit back, at MY expense, and have another unit sent, when a 5 cent part could be mailed out to me for the cost of a stamp. RIDICULOUS!!! Not too bright, or environmentally friendly. This is the problem with buying some things over the internet, from a place without a local retail outlet, but to save, we gamble...Now I either ship it back, hunt online or drive to local hardware stores and look for something that COULD work as a replacement. Grrrrr.....I finally went to Home Depot and found that they carried a package of #47 O-rings for a couple bucks that fit fine. All better now.THE UGLYThis Item is Ugly as sin. It reminds me of my pool filter. I am going to make or find something to cover it.OVERALLFor this price, it's an AWESOME deal!!!*** UPDATE - 07-06-2012 ***WOW time flies. I have had this filter now almost 3 years. It was used constantly for over a year, until I moved out of that City (YAY!!!). It then sat for about 6 months before I decided to hooked it up at my new place, so I wanted to open it to replace the filter.I was expecting the worst. First, it's not at all easy to open. I tried tapping it open with a hammer and a screw driver, on the bottom. I tried holding it between my legs and twisting hard. All attempts made me look silly. I eventually bought a cheapo Car Oil Filter changer wrench? at about $5.00, which worked perfectly. This, along with another pair of hands made it fairly easy to loosen.When I opened it, I was surprised. It wasn't as bad as I had thought it would be. After a year or more of use, and then sitting for 6 months, it was hardly dirty. I was expecting something that looked like the insides of an old Barroom Ice Maker, but it wasn't even close. I ended up tossing the old filter, which still looked hardly used. This in itself was amazing, considering how gross tasting and smelling Fitchburg's water was. The inside did show a little build up, and with its structural design, it had many nooks and crannies that needed cleaning out. I tried soap alone, but eventually I used a small screwdriver and paper towels to clean out the tough spots.I already had purchased a Level 2. 10 Inch replacement filter for it, but I ended up stealing a piece of rubber off the old filter to make it fit snug. It went back together easily and in about 5 minutes of running it was as good as the first day I tasted it.I just wish it wasn't SOOO Ugly. I had an idea when I first got it, to hide it's looks. I wanted to make a cover for it out of something waterproof and medium grey. Then I wanted to add big white eyes with black pupils and Large Dark Grey ears. That way it would look like an elephant. Maybe it would even make the kids drink more water? :)Anyway, the way this thing is built, it should last generations. There are still things for sale out there well worth the cost, and this is one of them. And who-ever builds my Idea, I want the first (or second) one...*** UPDATE - 09-06-2015 ***6 Years later and I'm back to buy my 3rd replacement filter. They last a lot longer than they say, although I probably should change more often. I wait until I can't take the slowness.When I open it, you can see the filter has done its job. I clean the nooks and cranny's with q-tips and some white vinegar. Be sure to pop the tube off (pulls right out, held in with two rubber o-rings) and clean it with something. I've seen some build up in there. Also, the push-pull thingy may need a little canola oil to lube it up. I posted where I found that idea in on of my comments. I thought I'd have to replace it, but it's still works good after 6 years of labor.Here's the filter I use and it does and Amazing job of cleaning my terrible towns water. KX Matrikx 06-250-125-975 Lead, Cyst, Chlorine Taste and Odor Reduction Filter, 10-Inch - www.amazon.com/gp/product/B00CNBB6ACSee you in 3 more years..... ### ⭐⭐⭐⭐⭐ Best sink filter I've ever tried *by U***I on Reviewed in the United States on September 30, 2012* I purchased this filter in September 2011 and have used it for one year now. Prior to purchasing this I had used PUR faucet mount filters over about six to eight years on and off,the infamous cylinder type one usually found in stores. I had three of those units over the years. They all cracked around the housings over time. They dida good job filtering but all broke. Took me 3 times to learn my lesson to not bother with PUR ever again. So I had gone hunting over a year ago and ended up giving this one a shot, despite it being a bit more filter thanI wanted but I had the room on my sink area for such a beast and preferred this over some under the sink unit as a replacement. The unit arrived and the first thing I did, in light of other comments about difficulty of opening the unit, was to open it and inspect. Mine was not overly difficult to unscrew. I did have a rubber strap wrench that I used (what home handy man doesn't have a strap wrench or two , eh?) to help me crack it open. No need for a back up wrench but it would come in handy if one had weaker hands than mine. Upon opening I inspected and decided to use a dab of silicon oil on the o-ring that seals the unit before re-assembling. This is nota bad idea if one has this unit as it will make future dis-assembly easier. Mounting the unit with the valve to the faucet was painless in my case. The diverter valve works perfectly. I will note at this stage the valve as noted in other reviews, did begin to stick after MONTHS of use. Reason? Simple lime build up.FIX? Simple application of vinegar on a dish towel, pulled the valve to the open position, lightly wrap soaked towel around the stem and allow to soak for a hour. At that point I just used my finger nail and tooth brush to remove deposits on the stem. At that point the valveworks as new until the next time it sticks months later. I don't know why people that have written reviews have failed to figure this out. Not a difficult thing to ponder out. On to the filter itself and how well it removes the taste of chlorine. On mine with MY municipel system, it works fine. As well asany of the PUR faucet systems I ever used does. When I bought the unit I aquired a spare filter http://www.amazon.com/gp/product/B000246SMS/ref=oh_details_o06_s00_i00 / KX MATRIKX Whole House Pb1, 10" Length (9.75" Actual), Extruded Carbon Block -- 0.5 micron -- Lead, Cyst, Chlorine Taste & Odor Reduction Replacement Water Filter Cartridge, 06-250-125-975 for future replacement (a step up I believe from what ships with the unit, unsure) I didn't feel the need to replace the filter in myunit until just over six months of use. For the record the water in my area varies in quality week to week. Sometimes it is almost as bad as pool water, other times no needat all to filter for taste. So how long this filter would last where you live would depend on local conditions. Iron content , etc. When I had to open the filter six months later this past spring, it was without great annoyance. I did have to use the rubber strapwrench I have to assist as I did when the unit was new. Again, as I had done six months prior, I applied a slight amount of SILICON oilto the o-ring. DO NOT USE VASELINE or any petroleum base if you do this. I suggest SILICON oil or a silicon grease. Only a small amount is needed to not slop it around. I used USDA of food approved (PURE silicon) without any petroleum. Not all SILICON oil is petroleum free. READ THE LABEL. If it has anypetroleum in it, I would not use it on rubber o-rings. You have been warned. So, despite what others have said in negative reviews I've had none of the problems. No leakage, no horrible issues with dis-assembly to replace the filter , no strange issues with the faucet valve (other than having to remove lime build up after couple months use (Simpleto fix with vinegar and a finger nail). One thing to note. If you have high water pressure or just plain HEALTHY pressure, do not open the tap full stroke and divert tothis filter. Use perhaps a quarter stroke (turn) to divert. The unit comes with instructions on expected FLOW rate. One can simplyuse a quart jar and a watch to judge how much YOUR faucet need to be opened and NO more when using this filter. I suspect mostthat have issues witht he filter perhaps cracking or leaking over time are slamming full pressure to the unit and exceeding pressures.At the best they are trying to push water too fast thru the filter and nto letting it do the full job it is capable of. SO figure out the flow rate and don't force the flow because you are in a rush or not paying attention. Bottom line. If you are on teh fence I would go with this unit ANY day over the PUR units which while they do do the job all tend to breakwithin a year of use. I suspect I could push the filter to 8 months of use prior to replacement the next time. Just depends on how much cholrine my supplierdecides to flood us with over the year. As with all filters of this type you do not run hot water thru it, or risk destroying carbon bit inside. Also, for those of you who dont' read instructions, flush this unit five full minutes before using for consumption. ### ⭐⭐⭐⭐ GREAT UNIT - Cheap Filter *by W***F on Reviewed in Canada on October 19, 2014* I had the Aquasana countertop system which uses 2 filters replaced every 6 months. It worked well but the cost of the filters was $53.99 U.S., which cost me about $60.89 Canadian, and hold-up time going through customs and crossing the border + potential additional charges by customs. I found the Watts CT-1 a desirable replacement. The only thing that made it a bit of a question was that it only had 1 filtering stage (Aquasana has 2) and would the water taste just as good.When I received the CT-1 I was pleased with its design and the fact that it had a separate dispensing spout. This is a personal preference and some people may not like it. The price was very good compared to Aquasana. However, when I tasted the water from the filter I did not like it, nor did my spouse. The water from the Aquasana tasted great, but the water from the Ct-1 unit had a sandy taste or something like that, maybe a bit sulphur-like. I looked into the filter used and found out that the filter that came with this unit is the absolute cheapest (under $10), and it was supposed to reduce chlorine taste and odour, sand, silt, sediment, and rust only. Well the taste was not appreciated. Also the manual said that you could only use their filters 101013, 101014, 101015, 100036, 101007, 101008 and 101009. The filter supplied with the unit is the 101008 (per newest manual) and it filters down to the 5 Micron level (very poor). The old manual indicated that the filter was the 1 Micron 101015 (this was better). The best one seems to be the 101014 or 101015 ($ 24.95 Canadian from Premier Filters) which filter down to the 1 Micron level. The manual warns you NOT to use other manufacturer' s filters because they may not work properly in the CT-1 unit. NOT TRUE. I searched the internet until I found a reputable filter dealer (GTAwater.com) and sent them a query.I discovered that their best TOP-OF-THE-LINE filter was the OMNI-CB3 which filtered everything down to the .5 micron level (10 times better than the filter provided with the CT-1 unit). They assured me that this filter would work properly in the CT-1 unit since they sold a unit that looked almost identical to the CT-1 but it was called the SPRING 1000.The OMNI-CB3 filter costs $45.99 Canadian and shipping is only $8.50 no matter how many filters you order. This works out to about 26 cents per day - a bargain for great tasting, well-filtered water! It is recommended to run water through a new filter for 3 minutes before drinking the water. This cleans out any loose particles in the filter and soaks the elements well enough to begin effective filtering.Since the filter should be replaced every 6 months, I bought 2 OMNI-CB3 filters. The cost is much lower than what I was paying for filters from Aquasana and the taste of the water is just as good as it was with the 2 Aquasana filters (great taste!). Also the OCB3 filter removes all sorts of pollutants and poisons down to the .5 micron level. These include Lead, Mercury, Chlorine, Rust, Sediment, Cryptosporidium & Giardia Cysts. Taste is enhanced and odour reduced. This filter is called a Cyst Reduction Cartridge, and it also removes VOCs (Volatile Organic Chemicals). This is just as good or possibly better than any other countertop system that I have investigated or owned (including Aquasana 2-stage).I replaced the filter that came with the Watts Premier CT-1 unit with the OMNI-CB3 filter. It fits perfectly and the water coming out of it is great!I found the following Flotec CB3 filter on this site. This filter appears to be equivalent to the OMNI-CB3, but at a better price! I should have checked before this ordering! Flotec CB3-SS Omni Carbon Block Undersink Replacement Water Filter Cartridge I gave the CT-1 package a 4 star rating because of the cheap filter that comes with the unit. The unit itself is great and deserves a 5-star rating (without the cheap filter). I guess they put in the cheapest filter to keep costs down and maintain a profit.I recommend this unit (not the filter in it) for anyone who wants simple, efficient counter-top water filtering. But be sure to buy better filters. Whenever you shop for water filtering systems always investigate the type of filters being used and if they will do what you expect them to do.
