  • What is the difference between an E type connection kit and a P type connection kit?

    The ‘E’ kit is for connection to a ½” stopcock / ½” under sink outlet or ¾” dishwasher connection.

    The ‘P’ kit is for connection to ½” copper pipe where there are no current outlets and generally needs to be done by a licensed plumber as the copper pipe has to be cut.

  • Is it normal to get small golden flakes in the shower filter cartridge packaging or brown flakes inside the shower filter?

    Parts of our filtration media are thin and brittle, meaning they can break down into smaller pieces through the mixing process, transport and use. It’s not uncommon to notice that some of the fines have escaped through the filter cartridge screen; this is normal, harmless and not a faulty filter. This is also more noticeable if you reverse the filter cartridges more often.

  • Will my Doulton or British Berkefeld filter element remove Chloramine?

    Chloramine may be removed by passing through a bed of activated carbon, but requires much greater contact time with the carbon than chlorine, so a slow flow rate through the carbon must be ensured.
    Unfortunately although the Doulton or British Berkefeld, Supersterasyl, Carbosyl, Supercarb and Ultracarb filter elements contain activated carbon, they may reduce levels but will not remove chloramine because there is insufficient contact time with the carbon.

  • What is the difference between 9” and 10” filters?

    A 9” and 10” filter refers to the length of the filter cartridge. The 9” cartridge is 9” or 227mm in length while the 10” cartridge is 9 ¾” or 247mm in length. The 10” cartridge size is more commonly used in bench top and under sink systems however the 9” size is standard for most Aqua Safe systems.

  • Will my Doulton® Ultracarb filter remove Chloramine?

    The Ultracarb filter can remove some chloramines or monochloramine, however it is only able to reduce it for a few hundred litres depending upon the level in the water. A different type or more specialised filters are required for this.

  • Why does the pH of my drinking water increase when I use my ceramic filter?

    The slight increase in the pH of water passing through the ceramic filters is due to the presence of the mineral Wollastonite in the ceramic. Wollastonite is slightly soluble and alkaline, so may partly dissolve in the water as it passes through the filter causing a minor pH shift which is harmless. No health based guideline value for pH in drinking water has been proposed by the WHO, although accompanying notes to the guidelines state that the pH range is often in the range of 6.5-9.5.

  • I live in rental house, so looking for a filter that I would be able to remove and take with me. Would it possible with AS280 Fluoride Removal Filtration System?

    The AS280 system needs a separate tap on the sink to dispense the water or a 3-In-1 flick mixer would be required instead of the existing sink flick mixer, or it could be installed under the sink with a valve on the outlet, however you would only be able to fill up jugs from under the sink. While the flick mixer could be swapped out on a temporary basis and an AS280 installed most clients either use a bench top filter or a QC350 system or an ASBTRO4. However only the AS280 and the RO system will reduce or remove fluoride.

  • Is this one of the few reverse osmosis filters that are portable? Does it require installation? I travel for work, so I cannot make holes in any benchtops etc. And how ling would a filter last, how expensive for replacements, and how easy is replacement?

    The ASBTRO4 needs to be connected to tap via the diverter valve, no other installation is required. This usually involves removing the taps aerator and connecting the diverter valve to it. 1 carbon filter needs to be replaced every year and the sediment filter every second year at a cost of $49.00 each. This takes approx 15 minutes to change.

  • Does the UV cartridge/ system require a power source.

    Ultra-violet (UV) systems require power to operate. They are usually plugged into 240VAC power supply and then reduced down to 24 or 12 volt to supply the system. They can connected to 24 or 12 volt AC or DC however this will alter the cost of the system.

  • When does a ceramic filter element need replacing?

    This depends on the type of ceramic filter being used: Sterasyl™ Should be replaced once cleaning fails to restore the water flow. The level of sediment and contaminants in the water will dictate the filter life. However, the manufacturer recommends that Sterasyl™ filters are replaced after 10,000 litres of water have passed through the filter, to guarantee optimum performance.

    Super Sterasyl™, Supercarb™, and Ultracarb™
    In combination filter elements (ceramic shells with internal filter media) cleaning the ceramic will not extend the life of the internal material. For example, the ‘life’ of the carbon block in Supercarb™ or Ultracarb™ filter elements is determined by the concentration of chlorine and/or volatile organic compounds in the water supply. This means that the life of the ceramic might or might not exceed the capacity of the carbon insert, depending on the water quality. Whichever point is reached first – the six months usage or the ceramic becoming blocked to the extent where cleaning does not restore the flow – governs when the filter element requires replacing. In most cases, the filter element should be replaced after 6 – 12 months of daily use. The following flow guidelines can be used to guarantee optimum performance:

    Super Sterasyl™ 2,000 litres,
    Supercarb™ 3,800 litres,
    Ultracarb™ 2,300 litres.

    After this amount of water has passed through the filter element, the filter will need to be replaced to guarantee optimum performance although the filter capacity can be up to 8000 litres in Australia due to the lower chlorine and chemical levels.

  • I've previously used the AS100 and was very pleased with it, but you're right, every year the replacement got harder and harder to untwist and re-twist. Is the difference between this and the A100 just the ease of replacement?

    The filter housing on the AS100 tends to become more difficult to undo and re-tighten as the system ages. To avoid this we suggest lubricating the o-ring every 1-2 years with a food grade lube. (can be purchased from Aqua Safe) This will prevent the 0-ring from gripping to the filter base making it difficult to get undone and difficult to seal when tightening back up. We would also suggest replacing the o-ring every few years to make the yearly service easier as well.

    The AS100SL system uses a different all in one filter cartridge and housing making it is very easy to change the filter, does not need lubricating and does not get harder to change with age. This system is purchased by many elderly customers for this reason.

  • The downside of chloramine, apart from containing ammonia, is the difficulty in removing it from drinking water. Standard GAC or Carbon Block water filters can only remove 10-25%. Is the AS001K9 effective at removing chloramines over its expected life?

    The rated capacity of the filters is generally based on chlorine removal under NSF certification or testing however many of our filters have been de-rated or the capacity reduced to allow for different conditions around the country. The 4000 litre capacity of the K9 & K10 filters is based on chlorine and needs to be reduced to 1800 litres for Chloramine, higher than a normal GAC due to the cartridge design and KDF media.

  • Does this filter work with low pressure, say a watertank?

    The AS100 filter comes standard with a 1 micron filter that requires some pressure to push the water through the filter. Low pressure from a water tank would result in the water coming out very slowly and may take a minute or two to fill a glass. In cases like these it maybe more feasible to either use a 10 micron filter or consider using a ceramic bench top urn.

  • How long do the filters last on tank water and what is the cost?

    The filters will last 6-12 months on tank water. As a general guide we suggest changing them every 6 months due to bacteria build-up being higher with tank water than town water. The cost varies from $32.00 to $90.00 depending upon the type of filter chosen.

    The AS001C10 filter has a similar performance to the Multipure filter with a lot lower cost. Both filters are manufactured in the USA and both are NSF standard 42 certified. The AS001C10 filter however is not NSF 53 certified for Giardia, Cryptosporidium and Cyst reduction although it will remove most if not all due to the sub-micron rating of the cartridge. The AS001C10 is also not designed to remove heavy metals although it can filter up to 10,000 litres as opposed to the 1500 litres for the Multipure.

  • What is the difference between the Pure-Cool and the Aquanet filter?

    The main difference is the performance or ability to remove chlorine and other chemicals. The Pure-cool filter is manufactured in the USA under quality control standards with samples from each batch tested to ensure adherence to the NSF standard and filter specifications. The unit is tested to remove greater than 99% of chlorine, taste and odour along with chloramines, chemicals and other contaminants.

    The Aquanet filter in made in Australia, has no NSF certification and medium to low removal rates of chlorine, chloramines and other contaminants based on independent testing.

  • What is the difference between this filter (the AS001F9) and the AS001K9 which I am currently using?

    The AS001F9 filter removes most of what the AS001K9 filter removes plus up to 40% of Fluoride. The AS001K9 removes no fluoride however does remove more heavy metals than the AS001F9 due to the specialised KDF media. The AS001F9 filter is normally selected if the customer wants to remove some Fluoride from the water.

  • What do shower filters remove from the water?

    The KDF and Chlorgon filtration media contained within the filters removes;

    • Free Chlorine
    • Combined Chlorine
    • Hydrogen Sulfide
    • Iron oxide (rust) and some other heavy metals
    • Coarse Dirt and sediment
    • Odours

    They also pH balance the water between 7 and 7.3 if the pH is low.

    To give added quality assurance the filters have been NSF Certified to Standard #177 for free chlorine removal.

  • How do shower filters work?

    Free chlorine is converted to harmless chloride (salt) as it passes through the filter. Iron oxide or rust/ brown water on the other hand deposits onto the filtration media, where it will remain until the next shower. It is recommended to flush or run the shower filter with warm water for a minute or two at the beginning of each shower to “reset” the media and flush away the ions. If there is a high concentration of iron oxide in your water, a whole of house filtration system designed specifically for iron removal may best suit your needs.

  • Why are the chlorine levels still high after my shower filter?

    This depends upon how you measure the chlorine levels and if you have a high quality filter. To test whether a shower filter is working or not, you need to measure free chlorine level not total or combined chlorine levels. For this you need to use a common DPD test kit or similar not and OTO kit as these test combined chlorine.

    Shower filters cause free chlorine to combine and become a harmless salt which affects the combined or total chlorine levels.

  • How do I clean a ceramic filter?

    Use a scouring pad (similar to 3M “Scotchbrite”). Ensure that the end of the filter do not come into contact with unfiltered water and dirty hands to avoid contamination. Rubber gloves are recommended to be used during cleaning and NEVER use soap or detergents!

  • My ceramic filter blocks up too regularly, what can I do about it?

    In some water conditions, there is so much sediment or bacteria and algae in the water supply that the filter element becomes blocked much quicker than in normal conditions. In these circumstances, it is beneficial to use a pre-filter upstream of the ceramic filter or try and eradicate the bacteria and algae through the use of a suitable sanitiser or Ultra Violet system. This prevents the filter from becoming blocked too quickly, minimises cleaning and extends the filter life.

  • Do I need to sterilise the candle after cleaning?

    The ceramic shell of Sterasyl™, Super Sterasyl™, Supercarb™, and Ultracarb™ filter elements all contain trace amounts of silver to prevent microbiological growth. These elements have anti-bacterial properties and should NOT be sterilised after cleaning. This included placing them in boiling water as this will damage the internal filter elements and the end seals.

  • How do I keep my filter housing clean?

    The filter housing is best cleaned by unscrewing the body or housing from the head and wiping the surface and the inside of the body with warm water and a cloth or sponge. Mild detergent can also be used although it is IMPORTANT – not to attempt to clean the filter head, which could cause contamination of the filtered water.

  • What happens if I leave the filter unused for a period of time?

    If normal use of the filter is interrupted by holidays or vacations, growth of harmless heterotrophic bacteria may result in a ‘flat’ or ‘stale’ taste for a period of time when use of the filter resumes. This is especially true for the filter elements that contain activated carbon such as the Super Sterasyl™ (contains granular activated carbon), the Supercarb™ and Ultracarb™ (both contain an extruded activated carbon core). Flushing the filter system for several minutes after any prolonged period of inactivity should eliminate the problem.

  • Will my Doulton® Ultracarb filter remove hardness?

    Ceramic and carbon filtration does not remove hardness (calcium and magnesium ions) from water so these filter elements will not affect the hardness in drinking water. The resin contained in the filter is also not designed to remove calcium ions from the water.  

    How much this was helpful

  • Will hardness affect the performance of an Ultracarb™ filter element?

    The ATS resin media used in the Ultracarb™ filters will adsorb lead and other heavy metals, even in the presence of calcium and magnesium ions. This is proven in the NSF certification testing. One of the test protocols for metal(s) reduction calls for testing at high pH, high Total Dissolved Solids (TDS) conditions to simulate use in hard waters. Filter elements containing ATS have to pass this part of the test protocol before they can receive NSF certification.

  • Will my Doulton® Ultracarb filter remove Iron?

    The Doulton® range of ceramic water filters are only suitable for the removal of iron in particulate form. They are not proven as suitable for treating dissolved iron.

  • Will my Doulton® Ceramic filter remove Legionella?

    Since Legionella has a similar morphology to E-coli, our ceramic filter elements should provide similar protection against Legionella. However, Legionella is capable of slow regrowth downstream of the filter, so if just one organism passes through the ceramic it could eventually colonise the water delivery system. Therefore it is important to regularly disinfect downstream of the filter or fit a Ultra-Violet light just after the filter.

  • Will my Doulton® filter remove Pseudamonas aeroginosa?

    Pseudomonas aeroginosa is a potential coloniser of water system networks and is similar in size to E-coli. Ceramic filters will therefore reduce this bacteria much the same as for E-coli. However, since this organism is rapid growing and may recover quickly, a <99.99% barrier maybe insufficient. A limited number of cells may pass through the filter which, unlike E-coli, may form colonies downstream of the filter. It would be best to combine filtration with a ultra-violet disinfection stage to ensure removal of Pseudomonas aeroginosa.

  • When does a ceramic filter element need replacing?

    Ceramic Only
    Once cleaning fails to restore the flow. Although, each individual candle does have a recommended capacity when used in normal conditions. The capacity for a specific element is quoted in within
    the section dedicated to each filter element’s construction and performance.
    Combination Filter Elements
    In dual function systems cleaning the ceramic will not extend the life of the internal material. For example: the ‘life’ of the extruded carbon block in the Supercarb filter elements is determined by the concentrations of chlorine and/or volatile organic compounds in the supply water. In most cases, the filter element should be replaced after 6 - 12 months of daily use or 1000 US gallons. The particulate and turbidity concentration in the supply water governs the life of the ceramic, which may exceed or not achieve the capacity of the carbon insert. Whichever point is reached first governs when the filter element requires replacing – the six months usage or the ceramic becoming blocked to the extent where cleaning does not restore the flow.

  • What is the difference between temporary and permanent hardness in water?

    Hardness caused by the presence of positively charged metal ions and total hardness is measured as the equivalent of milligrams per litre of calcium carbonate. There are two forms of hardness, temporary hardness which only contains metal carbonates and bicarbonates, the most typical being calcium carbonate. Temporary hardness is precipitated from water when heated and is responsible for the furring of heating elements and metal pipes. Permanent hardness consists of non-carbonate based metal salts, and does not
    precipitate out on heating.

  • Will my Doulton or British Berkefeld filter element remove all types of bacteria?

    No, there are so many different species of bacteria of different shape, size and growth characteristics, which preclude the ceramic filter from being effective against all of them. The pathogenic bacteria that
    FICL claim to be effective against have been qualified by test data from independent test laboratories or are extrapolated from test data, of similar microorganisms (please seek advice on permitted
    extrapolated claims).
    Also although the ceramic will filter all types of heterotrophic bacteria to some extent, it should be noted that any harmless bacteria of this type passing through the ceramic may multiply downstream of the filter. Since these heterotrophic bacteria are harmless, normally there are no problems and some heterotrophic bacteria are reported to be beneficial (see the section on Heterotrophic Bacteria pg 19).
    However, if normal use of the filter is interrupted by holidays or vacations, growth of these bacteria may result in a ‘flat' or ‘stale' taste for a period of time when use of the filter resumes. This is especially true for the filter elements that contain activated carbon such as the Super Sterasyl (contains granular activated carbon), the Supercarb and Ultracarb (both contain an extruded activated carbon core). Any system containing activated carbon, which will reduce residual levels of free chlorine, will result in an increase in plate counts over a short period of time until a constant state of equilibrium is established. The UK Drinking Water Inspectorate water regulations call for the water to be regularly monitored for
    consistency as used, therefore since an equilibrium point is reached in the filtered water, the filters comply with the regulations. The presence of this type heterotrophic bacteria does not constitute a health problem since the organisms present will be harmless and a suitable level of consistency would be established. Flushing the filter system for several minutes after any prolonged period of inactivity should eliminate the problem.

  • Will my Doulton or British Berkefeld remove diesel, petroleum or MTBE?

    The ceramic part of our filter elements will not take out any of these organic materials. The activated carbon in the Supercarb and Ultracarb filter elements will have some effect, however, to remove these type of materials requires much greater quantities of activated carbon and much longer contact time than our filters can provide.

  • Will my Doulton or British Berkefeld filter element remove Iron?

    The Doulton and British Berkefeld range of ceramic water filters are only suitable for the removal of iron in particulate form; they are not proven as suitable for treating dissolved iron. To treat water containing soluble iron, the iron must be oxidised to induce precipitation prior to filtration. Alternatively distillation or reverse osmosis can be used.

  • Will my Doulton or British Berkefeld filter element remove Legionella?

    Since Legionella has a similar morphology to E-coli our ceramic filter elements should provide similar protection against Legionella. However, Legionella is capable of slow regrowth downstream of the
    filter, so if just one organism passes through the ceramic it could eventually colonise the water delivery system. Therefore it is important to regularly disinfect downstream of the filter or fit a UV light just after the filter.

  • Will my Doulton or British Berkefeld filter element remove Manganese?

    No, to remove Manganese, oxidation treatment and filtration can be done, or for low levels of contamination, Green sand or Inversand can be used.

  • Will my Doulton or British Berkefeld filter element remove Nitrates?

    Unfortunately the ceramic filter elements will not remove nitrates. In the home the only effective method that can be used to remove nitrate is ion exchange media.

  • Will my Doulton or British Berkefeld filter element remove Oestrogen and Synthetic Oestrogen?

    There has been a limited amount of research into Oestrogen and Synthetic Oestrogen, and so we do not have quantifiable test data on the effectiveness of our products in removing it. Due to the chemical
    properties of Oestrogen, we believe that activated carbon would be effective in reducing it. However until better test methodology is available, we are unable make a claim.

  • Will my Doulton or British Berkefeld filter element remove Pseudamonas aeroginosa?

    Pseudomonas aeroginosa is a potential coloniser of water system networks and is similar in size to E-coli. FICL candles should therefore, in theory, show a similar reduction efficiency for Pseudomonas aeroginosa as E-coli 4.
    However, since this organism is rapid growing and may recover quickly. Without physically testing FICL ceramic filters with this type of organism, it is impossible to predict a performance claim.
    FICL are not prepared to attempt a prediction of performance, since the filters do not provide 100% barrier to E-coli, a limited number of cells may pass through the filter which, unlike E-coli may form colonies down stream of the filter. It would be more suitable to combine filtration with a disinfection stage to ensure removal of Pseudomonas aeroginosa.

  • Why does the pH of my drinking water increase when I use my ceramic filter?

    The slight increase in the pH of water passed through the ceramic filters is due to the presence of the mineral Wollastonite in the ceramic filter. Wollastonite is slightly soluble and alkaline, so may
    partly dissolve in the water as it passes through the filter causing a minor pH shift which is harmless. No health based guideline value for pH in drinking water has been proposed by the WHO, although accompanying notes to the guidelines state that the pH range is often in the range of 6.5-9.5. In general there is little evidence to suggest that pH in potable water of around 9-10 is of public health significance.

  • What level of bacterial contamination can the ceramic cope with before I need to use something else?

    In the absence of conclusive data regarding the levels of infective doses for specific pathogens, the FICL microbiological laboratory has been testing our filter elements for many years using an influent challenge of 6 log of E-Coli to substantiate the 4 log E-coli reduction claim that we make. This level of protection offered by the filters is more than adequate in all protected waters and the vast majority of moderately contaminated surface waters. However if the level of contamination in the water exceeds levels of 104 (4log) an additional
    treatment must be used such as disinfection or UV light treatment. It would be extremely unusual for water having a greater level of contamination than 104, to be considered suitable as a potable water source.

  • Which type of filter is more suitable for removing chloramines or monochloramine ?

    This depends upon if you are looking at a bench top or under bench system. Either way we would recommend an AS100, AS150 or AS200 system type with a AS001K cartridge. This system is able to treat approx 4000 litres for chloramines removal. If a higher volume is required we can supply specialised Chloramines removal cartridges that will fit into either of the above mentioned systems.

  • What is the difference between the following in-line Aquasafe filters (For main water line into caravan). High flow in-line filter AIC-K GAC & KDF 5 microns - vs - #17625 in-line 5 micron sediment filter.

    The main difference between the two caravan filters is the carbon filter is designed to remove sediment and chemical, taste and odour from the water supply while the sediment filter will only remove sediment and suspended particles from the water. The KDF media removes chlorine, heavy metals and treat hardness. The thread type on the sediment filter is ¼” NPT/ BSP.

  • Does the AS200CV system work in low water pressure applications, ie. Bore water.

    Yes it does however the flow rate from the filter system will drop as the water pressure decreases. This will also depend upon the filter cartridges used. Bore’s are generally always pumped so there should always be some pressure available. The finer or lower micron cartridges will reduce the pressure more. As long as there is at least 30-40 kPa pressure you will get water from the system with any combination of cartridges. Lower pressure than this will require higher 5-10 micron cartridges.
