Jenny, Any update on what you ended up doing? I installed a whole house softener for hard water issues, but I have odor issues (sulfur and chlorine mostly). I'm leaning toward adding a charcoal filter before the softener. We also have RO in the kitchen and wet bars. Also, you could always just have another hole drilled for the RO faucet without replacing the granite slab. If you have an undermounted sink, the new hole is all you need. What did you end up doing?

Hey Jake maybe I can be a little more clear on the Pure Water Appliance, and a little more helpful as I am more technically involved with the system and its design. First off there is no "magic sauce" or even a one size fits all approach with our unit. The machine is 3 compartmented so we can use a multitude of medias inside of our unit for different purposes. For instance in the state of Texas we use 85 different configurations of medias in this unit depending on the water it will be treating. When you ask what medias we use in the system the answer is quite a few of them. This solely depends on where the machine is going, and what it will have to remove to make drinking water in the whole house. That being said there are instances where the machine will not function 100% and in those instances we either add peripheral equipment to ensure the water quality going into the home. I.E a bad sulfur well, or a high TDS situation, or we simply will decline the use of the Pure Water Appliance. We DO NOT put the unit anywhere it will not function properly. That is why in the 4 years this thread has been operational it has not been flooded with bad reviews, and horror stories. Quite simply put if there is a problem with our unit it is simply fixed at no cost to our customers in any fashion. We actually guarantee our unit for 10 full years, and that covers everything on or in our unit including medias. So if our machine has a failure at 9 years 11 months, lets say either the second compartment, or third and the medias are no longer viable, then we simply replace the unit free of charge. No trip fee and no labor charge at all. Just to be clear the cost of replacing the unit at 9 years 11 months and 30 days is $0.00 usd . There is no company in the United states that can say that at all. Another thing I would like to add is that of course we design each compartment with proper space to expand and clean the medias properly. We actually use some ingenious flow screens that lift the beds evenly allowing us to clean more efficiently with less space. If you can lift a resin bed evenly you can reach your needed expansion in a smaller space. Also we use almost every media there is in the book redox, absorption, Ion exchange, filtration, you name a media that actually does what it is designed to do and we have probably used, or at least tested it's viability for use in our system. The way we build our units is off of proper testing of the water we will be treating, in all cities in Texas it is mandatory that they send water analysis reports to the state twice a year from multiple points of use in their water systems. We simply look at the water analysis reports for the last 20 years, make a projection of how we see the water changing, and design the system to the best of our ability for the next 20 years. We also recommend to our well customers that they have a full analysis done from a third party laboratory so we can build them exactly what they need, we offer our own base line testing, but anytime any one has their own well we always recommend labs off the TCEQ approved testing facilities. Does this machine work in every situation? absolutely not that's why if the machine wont work properly we either give an alternative set up that will take care of our customers problems, or recommend companies in their local area that can take care of them properly. We just design a system as bullet proof as we can, and back it with a non prorated warranty to protect and take care of our customers. No magic, no gimmicks just honest over the phone pricing, and proper service for our people. I'm sure this post wont be sufficient for you as I'm almost convinced you are a competitor hell bent on bashing our company. That is fine we know the warranty we have, we know the service we provide, and we will always take care of our customers, and even take care of customers that have been abandoned by shady inexperienced companies. We have been here for 37 years and will continue to be here for the foreseeable future.

Hi Nick, So that is the thing about water filters... they aren't something you want to set and forget. I've talked to people on here who are obsessed with water softener / carbon filter / iron filter / RO... and they forget that there aren't elves that come with each system. With virtually every system, not maintaining it is worse than not having it. The contaminants build up and then can be released in greater concentrations than what's going into the system. In general, carbon cartridge filters should be replaced after no more than a year. That's a general rule and there are exceptions. The reason is that they remove the residual disinfectant in the water and bacteria can build up in them. So I did a quick google search on Everpure H-100 and immediately came up with filters for $40 each. Honestly though, I'd look at paying someone to do something different there. You could do 1 filter to service both and a cheaper filter system (10" big blue). The big blue filter housing allows you to put in standard filters (or no filter at all). A carbon block filter that could service both (and probably then some) would cost you $30 a year. Just an FYI for others reading this: there's also a 20" big blue housing along with multiple stage housings. There are standard size filters that fit these larger housings. I have no connection to the website. I have just been a satisfied customer.

Normally I'm an advocate for a "big Blue" housing and a cartridge filter - but I was alerted to the Everpure EF-6000 which is a very good choice for your application. See this discussion on a Full flow filter. The replacement filters are $60 and should last a year.
