About Sydney 905 Filters

Being an ex Professional Land Surveyor, Justin Sadler who is the owner and managing director of Sydney 905 Filters ®, whilst out on surveys in both rural and urban settings, has seen and experienced the water woes effecting a majority of South Africa and Africa at large.

Seeing this and talking to the various affected individuals ignited his passion to provide an effective and fully sustainable solution in the provision of clean and safe water to all whilst advocating and supporting good environmental stewardship. This coupled with the tragic loss of their daughter, Sydney, who passed away on the 9/05/09, underpinned the establishment of the company, Sydney 905 Filters (Pty) Ltd, named in loving memory of her.

Sydney 905 Filters (Pty) Ltd is based on the South Coast of KwaZulu-Natal, South Africa and has designed, developed and supplies two globally unique filters, namely, the Sydney 905 Filter ® which is a 0.1 micron hollow fibre Point-of-Use (POU) water filter as well as the Sydney 905 Purifier ® which is a 0.01 micron hollow fibre POU water purifier. Both are very effective, cost efficient, fully sustainable and portable and will augment any existing water supply systems, whether improved or unimproved, urban or rural.

The company prides itself in its level of customer service and professionalism whilst still ensuring fair and competitive pricing. We are acutely aware that our product is vital to underpinning human and environmental betterment initiatives and thus make every endeavor to align our core capabilities to support these initiatives, both locally and internationally.

The company logo symbolises the human and environment's complementary, interconnected and interdependent relationship. This is personified in the Yin and Ying shape of the water droplet and leaf within the logo and with the all encompassing nurturing human arm and hand.

Yin and Yang is a concept of dualism in ancient Chinese philosophy, describing how seemingly opposite or contrary forces may actually be complementary, interconnected, and interdependent in the natural world, and how they may give rise to each other as they interrelate to one another. (Wikipedia,2015)

Yin and Yang shows balance where a portion of the opposite element is seen in each section of the symbol and one has no meaning without the other. The two halves that together complete the equilibrium of the wholeness.

Imagine A World

Imagine a world where everyone has access to clean water - where mothers can provide safe water to their families – where sickness doesn’t rob the children of their education through absenteeism. Imagine a world where money doesn’t have to be spent on buying medication for preventable waterborne diseases but is spent feeding hungry people. Imagine a world where parents can feel healthy enough to work and earn a living so they can help change their world for the better.


Fresh water, in sufficient quantity and quality, is essential for all aspects of life and sustainable development. It is a very good catalytic issue to facilitate the self empowerment processes. Water that is fit for human consumption must be clean and safe. It must be water that does not have offensive odour or colour, making it undesirable and unpalatable, and deterring people from drinking it. It must be desirable to drink it and people must have confidence that they can give it to their family with certainty that they are giving them water that is fresh, clean, clear, healthy and safe.

Unfortunately there are still billions of people that lack safe water, sanitation and handwashing facilities: 844 million people lack basic water services, 2.1 billion lack safely managed drinking water, 4.5 billion people lack access to safely managed sanitation and 892 million people still practice open defecation which contributes to the prevalence of waterborne diseases.


Sydney 905 Filters (Pty) Ltd manufactures and supplies two filters, namely, a 0.1 micron hollow fibre Point-of-Use (POU) water filter as well as a 0.01 micron hollow fibre POU water purifier that are both very effective, cost efficient, fully sustainable and portable and will augment any existing water supply systems, whether improved or unimproved.


While it has become clear that structural solutions may not be the panacea people once hoped for, science and technology can be a significant tool in designing cost-effective technologies that can be attractive to both rural and urban communities and improve their overall health and wellbeing. Decentralised or POU water collection and treatment systems are believed to be a cost-effective short-, medium or long-term sustainable solution to ensure rapid implementation of suitable water supply. Therefore, these filters can be used as an interim or final solution in the provision of clean and safe water to all.

It is the only filter globally, with this hollow fibre technology, that can thread directly onto a threaded water connection. It can thread onto a non-threaded connection by means of attaching the universal connector. The sustainability of this filter is due to the fact that there is no need to replace the filter cartridge (i.e. dependent on care taken of the filter and turbidity of the source water). They maintain their effectiveness throughout their lifespan which is determined by how well the user takes care of the filter and the environmental elements acting on the filter.
