Microplastics
What are microplastics?
Microplastics are small plastic particles typically defined as less than 5 mm in size. They may originate from the breakdown of larger plastics or be introduced through industrial and environmental pathways.
Microplastics have been detected in surface water, groundwater, and treated drinking water supplies.
How microplastics are reduced
Reduction methods include:
• Physical filtration
• Adsorptive and depth-filtration media
Effectiveness depends on particle size distribution, filter structure, and operating conditions.
Puratap testing and evidence
Puratap systems have undergone independent microplastics reduction testing.
Testing details:
• Testing performed by an independent laboratory in the United States
• Defined particle size ranges evaluated under controlled flow and pressure conditions
• Testing conducted according to established analytical protocols
• Results demonstrate reduction of microplastic particles within tested size ranges
Laboratory competence:
Testing followed systematic protocols for particle size evaluation, challenge water preparation, and filtration performance measurement under defined operating parameters.
Performance data available on request.
Certification context
• Product materials comply with AS 4020 potable water safety requirements
• Structural integrity verified under WaterMark hydrostatic testing
• Material safety confirmed through toxicity and leaching evaluation
Ongoing research
Microplastics testing protocols continue to develop as analytical methods and standardisation efforts advance. Independent laboratory testing provides evidence-based performance data within defined parameters.
