/ TECHNOLOGY
A century of air treatment tried to catch particles — or replace filters. We engineer the particles instead.
AIRBORNE PARTICLE ENGINEERING™
HiboScreen doesn't catch particles and doesn't replace your filter. It acts on the airstream, so the filter you already have can catch what it never could before.
A thin screen fits inside your existing air handling unit, immediately upstream of the primary filter — typically a G4 / MERV 8. It does not replace the filter. It does not collect particles itself. Its whole job is to re-engineer the air before it arrives.
THE SCREEN
A charged graphite screen, held at a uniform field.
A micronised-graphite coating on open-cell activated-carbon foam carries a 6 kV static charge, supplied by a low 24 VDC current at 50–100 µA. That creates a uniform curtain of field across the full airflow, with a low-voltage microscopic corona at the graphite tips.
Coating uniformity — which is what makes the field uniform — has been confirmed by Scanning Electron Microscopy at the University of York.
WHAT HAPPENS TO THE AIR
Polarise. Clump. Capture
Three steps, in the airstream, at AHU scale — every cubic metre that passes through.
01
Polarise
Fine particles acquire charge.
Air crosses a graphite-coated screen holding a uniform electric field, and fine particles passing through are polarised.
02
Clump
Charged particles fuse together. Polarised particles attract one another and combine into larger structures, too big to slip through.
03
Capture
Your existing filter does the rest. The standard G4 filter, which already catches large particles, now sees particles engineered into a size it can hold.
HiboScreen + G4 / MERV 8

F9 / MERV 15 / ISO ePM1 85%
NET RESULT · THIRD-PARTY VALIDATED
Single-pass equivalent to clinical-grade filtration — from the filter the building already owns.
WHY IT DOESN'T FADE
The screen engineers particles. It never loads up.
Conventional electrostatic media clogs and fades as it collects particulate. HiboScreen collects nothing — it keeps working at full strength. The filter, which is designed to load, does the capture and is replaced on your normal programme.
ANTI-MICROBIAL ACTION
The electrostatic field neutralises airborne pathogens.

VALIDATED BY SCIENCE
Coating uniformity, confirmed under the electron microscope.
A uniform field depends on a uniform coating. HiboScreen's micronised-graphite coating was confirmed by Scanning Electron Microscopy at the University of York.
A NEW CATEGORY
Not charge-and-collect. Not release-and-settle. Not charge-the-media.
HiboScreen is structurally different from every prior electrostatic approach — a category of its own: Airborne Particle Engineering™.
