Aredwood: Those particular filters are also available from almost any plumbing shop branded as Microlene / Davy water products. But AFAIK they are not rated to remove fluoride. I did a filter install job for someone who wanted to remove flouride. The only filter I could find that could reduce fluoride. Cost more, only lasts for 6 months, had a max flow rate of only 2L / min. Probably would have been cheaper for them to just buy bottled water. But if that water is mineral / spring. It would probably have a little fluoride as well.

If anything I would be more worried about hormones in the council supplied water than fluoride. As I have not been able to find out anything much that says either way. If hormones are or are not present in council supplied water. And if hormones are present, Then any claimed problems from fluoride will be insignificant in comparison. Looks like I will just have to pay for this study to find out. It was done at Auckland uni. So hopefully they used Auckland mains water for the study.

For the record I think adding fluoride to water is a great idea and it should continue.


Hormones in the drinking water? I've never heard of this, could you elaborate?
Also many filters just lump fluoride in with the other 'heavy metals' so there are definitely filters on the market which do operate for several years.
And nobody educated ever says that fluoride is bad for you, you absolutely need fluoride to function as a human being, but the key is the type of fluoride and the amount you're ingesting.
The fluoride we get lumped with, sodium fluoride, is waste product from the aluminum smelter in Bluff, not quite the same as the naturally occurring fluoride in ground water and vegetables.

Incindre:
As far as cooling is concerned, a quick Google couldn't find any products that do anything like what I think you want (a unit which filters and cools and filters your water under your kitchen bench). Although there is a Benchtop Cooler which is probably your most compact option.


I dont want something under bench. Something free standing (best) or countertop is what I want. But that one says to contact them for a quote which means they will start off stupid and I will have to bargain with them which defeats the purpose of buying online.

I was told by a company that sells water filters that only their 1 special cartridge remove fluoride. I would tend to believe them as their job is to sell water filters. Also the filters that remove heavy metals work by passing the water over pure Zinc. When heave metals come into contact with the zinc, a reduction reaction occurs. Which strips out the heavy metal oxides from the water. And in turn adds zinc oxide to the water. But this process only works for metals that are less reactive than Zinc. See the galvanic table. Since fluoride is more reactive than zinc. Any standard zinc based heavy metals removal filter can't remove fluoride. But can still remove alot of other heavy metals.

And again in reference to the last sentence of my previous post, For the record I think adding fluoride to water is a great idea and it should continue. So yes Im "pro fluoride" Im saying this as in your first post you say fluoride is bad. And in your second one that fluoride is good. So im confused as to what exactly you think about fluoride.

And will do another post later on my thoughts on hormones in the water. Mainly because I want more information on this.

In advance, I know I'm dragging this thread off topic, many soz.

Aredwood:For the record I think adding fluoride to water is a great idea and it should continue. So yes Im "pro fluoride" Im saying this as in your first post you say fluoride is bad. And in your second one that fluoride is good. So im confused as to what exactly you think about fluoride.


You're right, I was too charitable in my judgement of fluoride in that previous post.

I was told that Fluoride was an important part of your mineral intake in much the same way that Iron is an important nutrient. Turns out this is not true.
Fluoride is present in very small amounts in groundwater and vegetables, so it would be almost impossible to avoid if you wanted to, but it is not an essential nutrient, it's sole application for humans is to decrease incidents of tooth decay.

Fluoride works on your teeth most effectively through topical application, i.e. through your fluoridated toothpaste, NOT from ingesting water laced with fluoride.
So why on earth bother fluoridating the water supply when simply BRUSHING YOUR TEETH with a fluoride toothpaste will do a much more effective job? The card usually pulled here is that this is a boon for poorer communities who, for financial reasons, are less likely to see dentists on a regular basis. In essence, proponents of this argument are suggesting that the best way to improve the dental health of the downtrodden is to medicate EVERYBODY.

On principle I feel that I should have a choice in what medications I consume; I think it completely unnecessary that everyone from the smallest child to the oldest pensioner is receiving fluoride (which is being treated as a medication no less) in wildly varying quantities, controlled only by how much water they consume. You wouldn't be happy if your district council forced an indeterminate amount of antibiotics down your gullet every day because "it reduces the amount of bugs you'll get" irrespective of your current health status, but apparently it's fine for them to do that with fluoride irrespective of your personal dental hygiene/diet etc because it "reduces the amount of cavities you'll get".

Also, it is important to note that fluoride doesn't really exist on its own, it has to come from other compounds readily available on the market. You might think you're getting some pharmaceutically derived product added to your water, but you need to be significantly more cynical than this. Here's where things get stupid:
The fluoride added our water is actually either the waste product of the Bluff aluminium smelter (Sodium Fluoride) or from the plethora of superphosphate factories (Hexafluorosilicic Acid) that keep our dairy farmers in ryegrass.

Hexafluorosilicic Acid is the product of choice for the majority of the districts. It is created thusly: The fumes from the production of superphosphates are considered extremely toxic and it is illegal to vent them into the atmosphere, instead they are passed through a 'scrubbing' system where the toxic chemicals bind to water molecules in water jets, leaving the remaining gaseous waste in a state considered safe to vent to the atmosphere.
The water from this process (and its bonded chemicals) is now called 'Hexafluorosilicic Acid', and from there it is pumped into tankers and taken to whatever council fluoridation plant the factory has a contract with, and promptly metered out into the water supply.

It gets stupider because, instead of the councils getting paid to dispose of the fertilizer industry's waste for them, our glorious leaders actually PAY them for it (Hamilton City purchasing $40,000.00 worth per year).

So Yes, I'm 'Anti-Fluoride'.

Also, you appear to be right about your fluoride filtration thing, they do sell them separately and they only seem to last 12-18 months.

Aredwood:And will do another post later on my thoughts on hormones in the water. Mainly because I want more information on this.


It seems to be caused by sewage outflow into rivers. Urine from women on the pill results in high levels of estrogen in the water which is affecting fish life (as many can change gender). There is fear that these hormones will be carried through into the drinking water of those towns/cities further down the stream from the sewage outflows of other major cities.

The sunbeam ones that use the brita filter from Noel Leeming was one of the best purchases that I have ever made! All my flatmates including myself use it constantly all day!
