'Gravity 2' Filtration System (GS4-SCD)
The 'Gravity 2' comes with 4 'Sugalite' Candles
4 candles can produce 100 litres per day.
Systems with 4 can have their candles replaced every year as the capacity of the system as a whole is doubled.
There are a range of cartridge options depending upon your preferences and what you need to remove:
Contact us if you are unsure which would be right for you.
[√] ‘Jade’ (S-18-LM) for removal of harmful bacteria and parasites, perfect for in the field. All ceramic candles remove all dirt, sediment and rust from the water.
[√] ‘Ruby’ (SC-18-LM) for the removal of harmful bacteria and parasites but with Granular Activated Carbon for the further improvement of taste and odour.
[√] 'Sugalite' (SCD-22-LM) filter cartridges are supplied for purification of mains tap water. In addition to pathogenic bacteria, the Sugalite removes organic pollutants , such as agricultural pesticides and herbicides, chlorine, and dissolved heavy metals, such as cadmium, lead, mercury and copper.
Cartridge Add-Ons
Other cartridges can be fitted in conjunction with the main candles for more specific contaminant removal. One specialised element is required per candle. The elements screw onto the candle outlet in the lower chamber.
[√] Fluoride: can be removed using the FL-12-CP17 Fluoride Removal Cartridge. The addition of fluoride to drinking water has been linked to an increased risk of bone cancer and damage to the central nervous system. Click here for more details.
[√] Nitrate: can be removed using the N-12-CP17 Nitrate Removal Cartridge. Nitrates in drinking water have been associated with nitrate cyanosis and ‘blue baby syndrome’. Click here for more details.
Gravity Filter Systems: Optional Add-Ons
If you go with the standard 'Sugalite' filters then you will have the option to add an extra filter.
An extra filter will be fitted in conjunction with the main filters for more specific contaminant removal.
The extra filter screws onto the filter outlet in the lower chamber.
The following filters may be added:
[√] Malachite (FL-12-CP17) - Fluoride Removal Cartridge.
The addition of fluoride to drinking water has been linked to an increased risk of bone cancer and damage to the central nervous system.
[√] Jasper (N-12-CP17)- Nitrate Removal Cartridge.
Nitrates in drinking water have been associated with nitrate cyanosis and ‘blue baby syndrome’.

Gravity Filter Systems: How it works
These free standing units consist of two stainless steel containers with lid, tap and base ring. Impure water in the upper container percolates, under the force of gravity passes through ceramic filter candles into the lower container. A tap allows you to access pure, fresh, healthy water from the lower container.

Gravity Filtration: FAQs
1. Are gravity filters plumbed in?
2. What is the difference between GS2 and GS4?
3. Which cartridges should I choose?
4. What is a silverised ceramic?
5. Is it safe to use the filter if it has been idle for a long period?
6. What kind of flow rate should I expect?
7. How much water can the container hold?
8. Can I remove fluoride from my water?
9. Can I remove nitrates?
10. Can I remove limescale?
11. How often do I need to change the cartridges?
1. Are gravity filters plumbed in?
No, gravity filters are not plumbed in, which makes them great for use in temporary accommodation or out in the field where are ready supply of potable water is unavailable. To use, simply fill the upper container with water. The force of gravity means that dirty water passes though the ceramic cartridges and clean water collects in the lower cabinet.
2. What is the difference between GS2 and GS4?
The GS2 holds 2 filter cartridges whereas the GS4 holds 4 cartridges. The extra cartridges in the GS4 allow a faster flow rate. The GS4 can produce up to 100 litres per day
3. Which cartridges should I choose?
We sell 3 types of cartridges for our gravity filters.
For untreated water, choose either ‘Jade’ or ‘Ruby’:
• ‘Jade’ silverised ceramic (S-22-LM)- removes harmful bacteria and parasites. Perfect for use with untreated water, e.g. river water, where chemical contamination is less of an issue
• ‘Ruby’ silverised ceramic (SC-22-LM)- removes harmful bacteria and parasites. With granular activated carbon for further improvement of taste and odour.
For mains tap water, choose ‘Sugalite’:
• ‘Sugalite’ silverised ceramic (SCD-22-LM)- In addition to pathogenic bacteria, the Sugalite removes organic pollutants, such as agricultural pesticides and herbicides, chlorine, and dissolved heavy metals, such as cadmium, lead, mercury and copper. Recommended for filtration of mains tap water
4. What is a ‘silverised’ ceramic?
Our ceramic cartridges are impregnated with silver which prevents bacterial growth on the cartridge.
5. Is it safe to use the filter after it has been idle for a long period?
Yes, though it would be best to sanitise the unit before using it again. Add ‘Puritabs’ or another sterilising agent to water in the upper compartment and allow the solution to pass through the normal filtration process. This will remove any build up of bacteria that may have occurred. You may also want to clean the cartridges by brushing them gently under cold running water.
6. What kind of flow rate can I expect?
The GS2 can produce up to 40 litres of pure water a day. The GS4 can produce up to 80 litres.
7. How much water can the container hold?
The lower canister should hold around 8 litres of pure water.
8. Can I remove fluoride from my water?
Yes, by using our FL-12-CP17 Fluoride Removal Cartridge in addition to your regular cartridges you can remove fluoride.
9. Can I remove nitrates from my water?
Yes. Use our ‘Jasper N’ in addition to your regular cartridges to remove nitrate.
10. Can I remove limescale from my water?
No, the gravity filter does not remove hardness from your water. Minerals such as calcium and magnesium, which cause limescale, are considered extremely beneficial to health.
11. How often should I change the cartridges?
We recommend that you change your cartridges every six months to a year to maintain optimum performance.

Gravity Filtration: Troubleshooting
The reliability of the Gravity Filtration Systems is long established. However, if a problem should arise this easy guide should help to solve your problem. If not, call us on: 020 8123 8551 and we will do everything we can to assist you.
| PROBLEM | CAUSE/S | SOLUTIONS |
| No water | a) Dispensing tap is closed b) Ceramic candles are blocked with sediment |
a) Open dispensing tap b) Remove candles and clean by brushing them under cold running water. |
| Low water flow | a) Plastic covering on candle. b) Cartridge is reaching the end of its life. |
a) Check you have removed all wrappings from a new filter candle. b) As the cartridge filters contaminants from water, it becomes blocked. Clean cartridge by brushing under cold running water. c) If flow rate does not return to normal, replace cartridge. |
| Unpleasant water taste | Bacteria growth in chamber. | Sanitise the system. Place 3 ‘Puritabs’ in the upper container with cartridges. Fill the system with water and leave for 40 mins. Empty the chamber. |
| Dripping tap | Faulty tap | Replace tap. Buy (list of parts GSP-13) |
