We are Elrha, a force for change in the humanitarian community. The research and innovation we support equips the humanitarian community with the knowledge of what works, so people affected by crises get the right help when they need it most.
Our purpose is clear: to empower the humanitarian community to improve humanitarian response. We make this happen by supporting and championing the outcomes of robust research and proven innovations.

What is the humanitarian need?

The project aims to provide access to safe water in communities, which do not have it currently. Drinking water quality is improved at the point-of-use through consistent use of household water treatment.

What is the innovation solution?

The overall goal of our project is to develop methodology and assess effectiveness, acceptance, applicability and limitations of the household filters in humanitarian context. In our study, we evaluate five types of filters, pre-selected by the HIF technical working group and other experts. We implement our research methodology in three emergency settings, 120-150 filters per setting for the period of 8-10 month.
The main objectives of our study are:

  • to understand which filters are suitable for applications in emergency contexts;
  • to understand which features of the filters are valued by households and implementers;
  • to detect major difficulties and challenges users have regarding use, operation and maintenance of the filters;
  • to verify performance of the filters under different field settings and environments to provide feedback to manufacturers for further optimisation of the products.

What are the expected outcomes?

The outcomes of the project include:

  • A manual summarising background of the research methodology as well as user friendly step-by step approach to the field evaluation.
  • A report on the performance of the 5 types of filters in 3 different regional contexts. The report will focus on evaluation of filter features as well as potential for long-term application of the product in an emergency setting. Quantitative data obtained during laboratory and field evaluation will be summarised, analysed and discussed along with the qualitative data regarding user preferences and perception.
  • Final MCDA workshop with following expected outcomes:
    • most preferred filter and filter features based on the weighted scoring;
    • critical features and attributes for all and selected filters (weighted most and addressed least); and
    • comparison of the user preferences to the expert choice.
  • Written feedback to the manufacturers on which features of the filter are valued by the users, which are rejected and which might lead to failure as well as assessment of the performance in the laboratory and field conditions.
