FAQs for Gentoo Plus

This is activated carbon, naturally made from coconut shells. Usually they are a symptom that the filter hasn’t been prepared properly before use or there is an excess of activated in the filter.

You should repeat the filter preparation procedures.

Yes, we recommend keeping the jug full of water; this will prevent the filter from drying out.

Water generally starts to lose its alkalinity after 24 hours, but this can vary depending on how the water is stored and the temperature the water is kept in.

Water loses it alkalinity in general over 18-24 hours, but this depends on the methods used to alkaline the water, the amount of pollutant particles surrounding the alkaline water and what temperature the water is kept in.  Air carries PM2.5 and PM10 particles in it, so as soon as you unseal an alkaline water bottle, air gets inside the bottle and begins reducing the alkalinity of the water.

At least pH level 7.365.

• Energized ceramic material from UK
• KDF micro alloy particle technology from U.S.A
• Infra-red stone technology from Japan
• Assembled in Malaysia
• Designed in Australia

• Stage 1 - Fine Top mesh
• Stage 2 - Highly Effective Activated Carbon
• Stage 3 - KDF (Kinetic Degradation Fluxion)
• Stage 4 - Calcium Ionized Clay & Activated Alumina
• Stage 5 - Energised Ceramic 
• Stage 6 - Bottom Mesh

1. Fine top mesh - Pre-filtration 
2. Energising ceramic - Breaks down water molecules into smaller and aligned water clusters to increase water absorption properties.
3. Activated carbon - Effectively filters chlorine, chemicals, bacteria and organic pollutants
4. Kinetic Degradation Fluxion (KDF) - Filters heavy metals, prevents bacteria growth
5. Calcium Ionized Clay & Activated Alumina - Releases activated calcium ions and mild alkaline (pH 8.0 – 8.5) suitable for consumption and body absorption. Activated Alumina removes fluoride.
6. Bottom mesh - Prevents particle release

The Calcium Ionized Clay.

pH level 8 - 8.5.

We recommend you refill the Gentoo daily to ensure the water alkalinity is high and calcium residue doesn’t build up making it difficult to clean.

Generally you can tell whether the water is being filtered well by how fast it passes through the filters. Gentoo filters are very effective in filtering water. Depending on the water quality being filtered it can take 2 to 8 minutes to filter.

Yes, the Gentoo filters could removes up to 98% of fluoride. This will vary depending on the water source, alkalinity and age of filter.

Yes, we have independent tests carried out. However results can vary across the country as tap water can vary depending on its source, its pH level and how it is treated.

Yes, they are BPA (Bisphenol A) free.

It is important that you follow the instructions and prepare the filter properly before use. The filter should be kept moist at all times therefore we recommend that the jug is kept full of water.

As the water is exposed to the air it will eventually go stale, we recommend recycling the water every day to maintain freshness and prevent bacteria growth. Recommended period is within 48 hrs.

It is not necessary to refrigerate the water.

Yes, you can. However, it will alter the effectiveness and the life span of the filter as the filters are specifically manufactured for treated tap water.

This is usually a sign of a blocked filter, remove filter from the jug and rinse under running tap water for a few minutes.

It normally takes 2 – 8 minutes for the water to be filtered, if it is extremely slow it could be that there is a blockage in the filter. To remove blockage take filter out of jug and rinse in running tap water for a few minutes. Clean underside of filter with a soft brush.

The media we use is activated alumina. The process works by ion exchange, as the water flows through the filter it comes into contact with the media (activated alumina), the fluoride is attracted to the activated alumina and is absorbed.

Activated Alumina is generally specific to fluoride and is probably the most commonly used fluoride removal technology today.

This process is known to remove up to 98% of the fluoride in water.

No, it is a seal so it must remain on the filter.

Yes, the filters are recyclable. Depending on your council, they can be dropped to your local resource recovery centres for free or placed in your recycling bin. Please check with your local for further information.
