New frontier for mask technology
HydroCharge is MEDICOS’ most powerful filtration technology to date. It is a revolutionary water electret process that embeds water electret charge deep into all MEDICOS HydroCharge Sub Micron Filters.
A remarkably more powerful filtration system
MEDICOS HydroCharge Sub Micron Filters are able to decrease air resistance by to 70% and achieve 3x the electret charge saturation compared to traditional meltblown filters.
You get more
With HydroCharge, you get more protection, more comfort and more breathability without ever needing to increase the thickness of your masks.
Better real-world performance
HydroCharge is both lab-tested and real-world tested for maximum protection and breathability, assuring the best overall protection when using MEDICOS HydroCharge Sub Micron Surgical Face Masks.
The HydroCharge Technology
Why are meltblown filters charged with electrostatic?
To understand HydroCharge, we must first understand why meltblown filters are charged in the first place.
The core of medical-grade face masks is meltblown. Electrostatic properties on the surface of meltblown filters help to trap aerosolized particles via electrostatic attraction.
The electret process creates friction and generates static electricity which enables high performance face masks to filter and trap particles as small as 0.1 microns.
To put things into perspective, our human hair diameter is approximately 70 microns. Our human eye cannot see anything that is smaller than 50 microns.
According to World Health Organisation (WHO), the droplet particle size that transmits the SARS-COV-2 Covid-19 virus is about 5 to 10 microns.
The challenges of the traditional method
To produce medical-grade face masks with high performance particle filtration, the traditional method is to charge the surface of the meltblown filter with electrostatic by using the ‘corona thermal electret method’.
The first major challenge of traditional corona thermal process is that the electrostatic generated is only temporary and it will degrade over time.
Secondly, the traditional process charges only the surface level of the meltblown filter and it is not evenly distributed.
That’s why common face masks cannot retain the peak filtration efficiency for an extended period of time in storage.
The water electret method
MEDICOS HydroCharge Sub Micron Filter goes through a revolutionary and delicate process known as the water electret method.
The meltblown fabric goes through penetrative jets of water or a stream of water droplets into the meltblown cloth at a precise angle, pressure and flow rate.
Lab tests have proven that by going through this hydro-embedding process, the meltblown cloth develops a strong, permanent filtration-enhancing electret charge.
After going through the water electret process, MEDICOS HydroCharge Sub Micron Filter undergoes a drying process to eliminate any excess electricity on the surface, also known as virtual electricity.
The meltblown cloth goes through the dryer which uses hot air flow. Virtual electricity is removed during this process and the electret embedded on the meltblown filter is assured to be permanent.
Testing beyond the industry standard
Lab-test reports and actual performance can vary when real-world forces are at play. That is why HydroCharge is made and tested for real-world performance. It is engineered for optimum filtration efficiency and flow-rate to minimise air inhale and exhale leakages through the edges of the face mask.
