Reverse Osmosis (fluoride mitigation) Water Filter Query Summary & Revision Request

Hey CM.com Community,

As an update and revision to a previous post on Water Filters that remove fluoride and chlorine...

The Big Berkey, Katadyn, St. Paul Mercantile and Dr. Mercola products were excellent recommendations if you needed a travel or portable water filter, one that did not need to filter for fluoride, lived in a property where a an entire house filter was an option and/or were not necessarily looking for something that attached to a kitchen counter top or under the the sink.

However...

I need one for use in a condo/hotel kitchen counter top or under sink, in an area that has less than desirable tap water quality, heavily fluoridates its water and in where the unit that can serve the dual or multi-purpose of providing clean drinking water, filtering the water from the faucet for washing fruits & vegetable/cooking and/or could possibly be connected to an ice maker or fridge if desired.

It seems like a Reverse Osmosis (RO) water filter seems like the best option for this specific case. I understand that travel and portable ones meet other or perhaps even most needs.

Anybody have any experience with one or recommend a particular nmodel that fits the criteria and needs above? Am I missing something or incorrectly assessing the best fit?

Also, I've read conflicting info on whether or not minerals should be added to the RO filtered water for ideal drinking purposes. Is this necessary or simply a water nutrition enhancement option? 

I'd really appreciate some quick precise feedback on this as I'm looking to purchase one this weekend. Any heads ups on good sales would be very helpful as well. Thanks in advance!

Best,

JG

UPDATE: Looks like a viable option for the needs I listed is...

the Premier Reverse Osmosis 5 Stage Water Filter from Costco.

Seems like it does the job and not a bad price.

Just in case anybody was interested. Please do post any other suggestions if you have direct experience with another model. Thanks.

Beware reverse osmosis

I haven't researched the topic thoroughly, but for what I've seen so far I don't trust reverse osmosis systems.

 

From the WHO:

Drinking water should contain minimum levels of certain essential minerals (and other components such as carbonates). Unfortunately, over the two past decades, little research attention has been given to the beneficial or protective effects of drinking water substances. The main focus has been on the toxicological properties of contaminants. Nevertheless, some studies have attempted to define the minimum content of essential elements or TDS in drinking water, and some countries have included requirements or guidelines for selected substances in their drinking water regulations. The issue is relevant not only where drinking water is obtained by desalination (if not adequately re-mineralised) but also where home treatment or central water treatment reduces the content of important minerals and low-mineral bottled water is consumed.

From Berkey (they sell water purifiers that don't rely on reverse osmosis, so double-check their facts):

Healthfulness of Reverse Osmosis and Distillation  Based on current research, most health experts are no longer recommending drinking RO or distilled water on a long-term basis because these methods strip out all of the beneficial minerals from the water, making the water an acidic “hypotonic” solution. A chemist will tell you that when a hypotonic (de-mineralized) solution comes into contact with a “hypertonic” (mineralized) solution, the minerals within the hypertonic solution will transfer out of hypertonic solution and into the hypotonic solution until equilibrium is achieved. What this simply means is  that when one drinks hypotonic water, the minerals in the blood and lymphatic system, which are hypertonic, transfer into the hypotonic RO or Distilled water that is consumed and the minerals are flushed out of the body upon urination. In an effort to re-mineralize, the blood and lymphatic systems then begin to scavenge for minerals from other parts of the body, such as bones and other organs, and this process repeats itself every time de-mineralized hypotonic water is re-consumed. Several studies suggest that people who drink de-mineralized water (hypotonic) over a long period of time tend to be more prone to degenerative diseases such as osteoporosis. Berkey® Purification systems do not remove all of the beneficial minerals from the water, but they do extract harmful heavy metals such as lead and mercury as well as sedimentary minerals such as iron oxide. Therefore, the TDS reading will not typically change much unless there are a lot of heavy metals or sedimentary minerals within the source water.

TDS is actually the least effective type of test to determine whether water is suitable to drink. In actuality, most involved in this type of discussion are unaware and don't understand the variety of sciences concerning water filtration. Typically this type of discussion arises from those promoting the use of RO and Distillation methods, which drastically reduce TDS. Unfortunately, such water is acidic, is never found in nature, and therefore can confuse the body, which typically will attempt to re-mineralize such water by robbing essential minerals from the body.
