  • Looking for undersink water filter

    Recently I noticed that there is some smell in the city water. After doing some research online, I feel it's necessary to install an undersink water filter. However I have no clue which brand and model is better (everyone claim they are the best). any recommendations?

    My concern about the water is the odor and lead in the water - heard the City still got a lot of old lead pipes (or pipes contains lead) to replace.

    Thanks.

    I use a Whirlpool WHER25 RO filter. They cost around $150+ tax US$.

    I change the pre and post filters every 6 months and the RO cartridge every 18 months. The filters cost around $38 and the RO cartridge about $50.

    The only problem I've had with it in 3 years was about 2 weeks ago. The diaphragm cracked and flooded under the cabinet. Whirlpool sent me the diaphragm kit and plunger free of charge.

      You need to address the water quality issue with the city of Oshawa. If your water smells , there is a reason why (even though it may not be a health concern). Lead will not make your water smell. But on the lead issue, check your water line coming into the house. Those were made of lead in the Toronto area 60-100 years ago. The water mains on your street are most likely cast iron, not lead. If you have a lead water line into your house have it replaced (many cities have a cash rebate program when doing this work). In the mean while, if you have lead, let the water run when it has remained in the pipes for some time (say overnight) before you use it.

        The smell from the water could be caused by sulfer in the water, which is more common with houses that have wells but certainly can happy with city as well. Different chemicals they use can cause a bad smell as well as certain types of bacteria. Rusty pipes can cause an odor but often it will discolor your water as well.

          Is it a reverse osmosis filter? I'm thinking a 2-stage (fine filter + activated carbon) non-RO shall be good enough for me.

            Look for a coconut carbon filter cartridge system.Coconut carbon is heated to a point that has very small openings and will remove bacteria,chlorine,and most pharmaceuticals.

            RO Systems throw away four gallons to make one and is acidic.Heart patients,high blood pressure patients shouold not drink this. PS I have both of these issues and this came from the heart specialist.

              I saw a lot of brands such as GE/Watts at Home Depot, whirlpool at Lowes. Possibly there are many other brands on the market. Do you know which brand and model is good? I have never used any water filter before.

                Working for a school district, I have to maintain at least 20 R.O. systems twice a year. If you stick with the models that use a universal style cartridge, you can buy them anywhere at the best price. The models that only use a special size filter that only one manufacture sells will be much more expensive to replace and buying them from only a few available outlets.

                  Yes, it is.

                    I absolutely hate cartridge in line filters usually called Whole House Filters. Yes you can buy them in gangs of two three and even four if you like. Problem is, they won't remove anything that's bad for you except possibly chlorine (with a carbon filter).

                    One of the problems you may have is the lack of chlorine. You may be getting the odor from bacteria. I have friends that live in a community that is obviously the last place in line with the county water main. Their water stinks all the time. Let it run for a while, the smell goes away. That's bacteria. My Dad's a snowbird, here six months, up north six months. We have to go down and chlorinate his well and plumbing each year before he comes back. The water stinks until we do. Then it's good for the duration until the place is closed up again and no water is run. The bacteria grows into large colonies and starts the stinking all over again.

                      I have the everpure H300 that uses coconut carbon.I have it installed at my bar and kitchen.You do need a seperate glass filler for this type filter and you will need a seperate glass filler for the ro system.It does not deliver enough water to install with a traditional kitchen faucet.

                      Keep in mind with an ro system there is only a gallon and half or 2 gallon tank. If you have family or installed with the refer water and ice you may run out of water and must wait 24 hours for it to replenish.

                      I am not a fan of ro systems due to how acidic it is.That is why they use plastic water lines and the glass filler should be lined with plastic. A whole house ro system must be maintained if not you are asking for trouble.

                          Here in So. Cal we have a safe water supply its just tastes like ####. Reverse Osmosis is the best option for TASTE, although its not a perfect solution. I install 24 gallon per day units with 2.5 gallon storage tank. When I install the unit in a garage I'll install a permeate pump with the R.O. its reduces waste water by @ half. it makes a little clicking sound so some customers find it annoying in the kitchen.

                          Biggest issue I have is people don't maintain them, they figure if water comes out of the spigot its working

                          Everpure is a good filter but way over priced. You can put together the same type of filter system using generic 10" cannisters including the coconut carbon which I agree is top shelf, I incorporate them in my R.O. systems.

                          Got to mention I installed a zero waste water system that the customer provided from costco. I was skeptical but have done 1 yearly service so far and was performing great. We'll see this summer when I do the second year service. It pumps the waste water back into hot water line Install and unit is little more than usual but seems to be working. If its still performing good on the next service I'll incorporate the technology into the units I install.
