Botanical laboratories require stringent contamination control measures to maintain pharmaceutical-grade environments. This case study examines the successful implementation of Electrostatic filter screens, an innovative antimicrobial filtration solution, to address the challenges of bacterial and fungal contamination. Electrostatic filter screens incorporating HiboTechnology-coated porous foam, was integrated into the laboratory’s existing filtration system. The system integrates seamlessly into existing setups, thanks to its low-pressure drop, compact design, and minimal power requirements (220V, 3W). Its inclusion in the latter stages of the facility design proved effortless, underscoring its adaptability.
Key Features of Electrostatic Filter Screens:
- HiboTechnology-coated porous foam for antimicrobial action.
- Protective grid and custom-sized plastic framing for versatility.
- Energy-efficient operation with a low carbon footprint.
Implementation and Testing: Side-by-Side Comparisons.
The laboratory installed three filter boxes to test different setups:
- Unit 1: G4 and F9 filters (no Electrostatic Filter Screen).
- Unit 2: Electrostatic Filter Screen, G4, and F9 filters.
- Outside Air Filter Box: Electrostatic Filter Screen, G4, and F9 filters.
- Cleanroom Validation: Unit 2 achieved ISO 7 cleanliness standards without HEPA filters, compared to ISO 8 in Unit 1.
- Filter Performance: Primary filters in Unit 2 remained free from mould and dust clumps, significantly extending their lifespan.
- Air Duct and HVAC Coil Maintenance:
- Coils remained as clean as new after 1.5 years, eliminating maintenance costs.
- Supply ducts were free of mould, a primary cause of “Sick Building Syndrome.”
This case study demonstrates that Electrostatic Filter Screens is a game-changer in cleanroom filtration. It not only enhances air quality but also reduces operational costs and promotes healthier indoor environments. By charging and clumping fine particles, it acts as a first line of defense, making secondary filters redundant in many cases. Electrostatic Filter Screens represents a step forward in creating greener, healthier, and more efficient facilities. Whether in botanical labs or other contamination-prone environments, its ability to deliver cleaner, better, and more economical air is unparalleled.
