Q: Why are there black grains in the filtered water?

The black grains are the activated carbon in the filter which are used for reducing chemical substances in water like chlorine and pharmaceuticals.  Since the activated carbon is easily broken during transport, it is recommended to discard the first two pitchers of filtered water when using the filter for the first time. These grains will not cause any negative impact on health if you drink them accidentally as they pass through the body harmlessly. Pure Charcoal tablets and sticks are a good example of this. 

Q: What Minerals are added back into the water? 

The minerals that are reintroduced are Zinc, Selenium, trace potassium and magnesium. This is done with mineral balls. We also use zeolite minerals to absorb some harmful elements as well as introduce antioxidants.

Q: Has the filter been tested by any impartial third party?

 The filter has been certified by well known international certification SGS.  The materials’ quality is ensured as well as independently tested by the UKs Stansted’s labs and Biolabs London. 

Q: Does it remove chlorine or metals?

The chlorine is removed by the activated carbon (the small particles you sometimes get when you first rinse your filter for the first time), and the metals are removed by the rest of the filter media in the filter. After the metals are removed. The water is then remineralised to give you the benefits and taste of mineral water.

Q: What is the waters PH after filtration.

The Klar water filter will shift the waters PH by an average of 2.2 towards alkaline, so depending on your water source expect results ranging from 7.5 – 9. The best way to test is to use reagent drops not PH testing strips.  

Q: Does the Klar remove Fluoride?

Yes it does. We made Klar with this specific goal in mind and we have been able to achieve 90-95% removal of fluoride in drinking water depending on the water source.

Q: Does Klar remove microplastics?

Yes it does. Klar is able to filter out microplastics down to 0.5 microns which will remove the vast majority of plastic particles reported to be found in tap and bottled water.

Q: Does it remove pharmaceuticals/hormones?

Yes, the activated carbon stage of the filter can remove up to 95% of common pharmaceuticals and hormones.

Q: Does Klar need to be kept in the fridge?

No, the Klar water filter does not need to be kept in the fridge as the filter contains Silver which will inhibit the growth of bacteria inside the replacement cartridge.

Q: Does it filter THMS?

Yes it does, the activated carbon in the filter performs this role.

Q: How long will a filter last?

The filter cartridge will last 2 months or 350 litres of water which is around 5 litres per day of filtering.

Q: Why are the TDS readings high after filtration?

Due to the fact that Klar remineralises the water after filtration (which also gives the waters its alkalinity) the TDS (Total dissolvable solids) will be higher than some other filters. Depending on the water source, expect a TDS reading of around a 190-250.

Q: How often do I need to clean the Jug?

We advise cleaning it every time you change the cartridge, which is every two months.

Q: What plasic is the Jug made from?

The jug is made from plastics ‘5’, which is the same used in baby bottles.

Q: Is the Jug BPA free?

Yes the jug is free from BPA and Phthalates.

Q: Can I put the jug in the dish washer?

We do not advise you put the jug in the dishwasher until we have performed enough tests. Please wash the jug by hand for now.

Q: Does Klar reduce limescale?

Since Klar remineralises after filtration, you will see a small reduction of limescale but not a compete eradication as some mineral residue will still be left after boiling. 

Q: Removing the blue sticker.

Please make sure you remove the blue sticker from the bottom of the replacement filter before washing and rinsing.

Q: Does the water need to be boiled after filtering?

If your tap water is qualified to be drinkable, you can drink the filtered water directly. If However your tap water is not certified drinkable then you would have to boil.
