Myths & FAQ's

Let’s dispel some myths/ Bull S+*T (BS) stories that are getting around the water industry.

Firstly, let’s start with the big one which is Fluoride removal:

Q: Can fluoride be removed with a carbon filter?

A: NO! For the first 30-50 litres or so which is called the Honeymoon period of a filter test, yes there is some fluoride reduction of sorts (30-40% are the claims so far made that we’ve seen) but it would be misleading to tell people that it was a fluoride removal option. They definitely don’t make it evident that results were completely different after the honeymoon period had ended and carbon then proved itself to be not affective at all in removing fluoride.

So the answer here should be a resounding NO IT DOESN’T REMOVE FLUORIDE!

Q: Do you sell the Ceramic filters with magic volcanic rocks in them to remove fluoride?

A: NO! We have never seen any data to show that ceramic filtration does anything at all remotely close to removing fluoride nor have we seen anything on these so called magic volcanic rocks but we’ve seen some pretty vague attempts at claiming whole house fluoride removal systems of the sort. This is of course an outright false claim by that company and hopefully this company is closed down soon before too many people buy their dud filters.

Q: Can a resin filter cartridge remove fluoride?

A: YES BUT, it is very short lived and not considered a viable option for fluoride removal at all.

Here is the reason why: Resin does an excellent job at removing virtually all impurities from water, fluoride included, but that’s why it’s not a viable option for fluoride removal.

Take Brisbane’s town water for instance, we see Totally Dissolved Solids (TDS) readings ranging from 80 parts per million (ppm) to 367ppm which is our record high reading taken from the suburb of Forestdale. Let’s halve those extremes and use an average of say 223ppm which is very common across Brisbane.

Resin is rated in a unit of measure called a GRAIN. 1 GRAIN will absorb approximately 17.1ppm of TDS. So if a standard 9 ¾” 100% resin cartridge (usually around 400 grains of resin) is used it would equate to something like this:

400 x 17.1 = 6,840 ppm removal of TDS. So how much water could you purify with a resin cartridge such as this? Well you simply divide 6,840 by your TDS reading; say 223ppm and you have 30.67 litres of pure water per resin cartridge. That’ll be another $80 or so for another Deionising resin cartridge thankyou!

Please let us know if you would still wish to use this method of fluoride removal despite the huge cost as we are happy to provide you with a new $80 filter every 3-4 days. We’ll even give you a bulk discount on your 1 month supply of filter cartridges.

Q: Is there a filter cartridge that can remove fluoride?

A: YES. There are ‘activated alumina crystal’ filter cartridges available in our online store. They utilise alumina to absorb a claimed 90% of fluoride for up to 1,900 litres. We have been provided with test data from the manufacturer that shows these figures but we could not get a figure on the increased alumina levels in the water after the ‘activated alumina crystal’ cartridge.

If your concerns are not so much about the increased aluminium levels in the water, which by the way is put into your town drinking water supply as Alum (a flocculent which makes particles coagulate and sink to the bottom of the tank during the water treatment process) then this 9 ¾” activated alumina crystal filter cartridge will fit in the place of your sediment filter (must be prior to your carbon filter for taste correction) and you have a fluoride removal (90%) without modification to your existing 9 3/4” filter system. These cartridges are definitely not cheap at $122 each providing a claimed 1,900 litres of treatment which is around 5 litres per day for 12 months.

The ‘activated alumina crystal’ cartridge is different to a resin cartridge in that it only targets the fluoride in the water and not other impurities.

Q: My child/ family member has copper poisoning, what can I do to remove it from our drinking water?

A: Reverse osmosis filtration or make your own water from the air, are two options most commonly given.

It is amazing just how many people contact us regarding mainly their children who have major issues copper in their water.

Q: Can carbon or ceramic filters remove copper from the water?

A: It is claimed by some filter companies that their carbon based filter cartridges reduce copper levels to untraceable levels. This claim is not the whole truth and they have in some cases been quick to remove their claims before they get into trouble for misleading people with false claims. Their tests showed copper reduction levels only during the honeymoon period (first 30-50 litres or so) after which virtually no copper reduction was recorded at all. Manufacturers specifications sheets that claim a reduction in copper with the use of carbon or ceramic but conveniently omitted important information such as how much water was treated before the test was conducted which makes the results misleading. Best advice we can give is to steer clear of that product and go with a trusted brand that doesn't need to trick people to make sales.  

So the answer here should be a resounding NO, CARBON OR CERAMIC FILTERS DO NOT REMOVE COPPER!

Q: I want the best quality water for my family so tell me what do you use?

This is what I like to hear. It’s an indication that the customer doesn’t have any preconceived ideas from people who have no idea about water filtration and that they just want the best water filtration system straight up.

A: My answer is always, I make my own water from the air with a Dragonfly air to water machine as well as a Reverse Osmosis filtration system for cooking, high demand periods and during the winter months when water production by the Dragonfly tends to be very low. To use just a reverse osmosis filter system would be perfectly OK, it's just I prefer to have as little chemical exposure as possible in my water supply and choose to use both.
