Filtration challenge
ChatGPT a dit :
The information provided by the client was as follows:
- Filter dimensions: 305 × 305 × 68 mm
- Filter seal: foam
- Filter frame: aluminium
The client also wanted to reduce the manufacturing and supply lead time for filtration materials to 3–4 weeks. Delivery requirements were:
- 700 filters per year, in 3 batches
- Packaging of 2 filters per box
- Inclusion of all necessary certificates and attestations
This evolution had to be implemented while maintaining the company’s competitiveness and keeping manufacturing costs under control, in a highly competitive environment.

We therefore proposed that the client use HEPA filters from a manufacturer already approved by them, offering a competitive price aligned with their production budget constraints.
We met their regulatory requirements by providing all necessary documentation: ISO 9001 certificate, EUROVENT certificate, and control certificates.
We implemented delivery in batches of 2, as requested. Each filter is supplied in an individual plastic bag with its own certificate of conformity and identified by its serial number, ensuring full traceability.
We also guarantee a supply lead time of 3 to 4 weeks, with the possibility of reducing this to 48 hours, free of charge, through the establishment of a buffer stock at our facility.
Our teams also recommended replacing the foam gasket initially specified in the requirements with a continuous rounded-edge gasket to improve system sealing. This modification was carried out by the client and proved effective:
Finally, adjustments were made to the filtration system to remove the flow direction marking on the filter, simplifying installation for operators and subsequent routine replacement by the client.
This resulted in multiple benefits for the client:
- A significant reduction in filter delivery times compared with the previous supplier (3 to 4 weeks versus 8)
- Economic savings
- Improved filtration system sealing thanks to the gasket replacement based on our recommendations.
