N95 FACE-MASK (CORONA VIRUS PROTECTION) |
|
Bothered by dust, pollution and air-borne diseases? Breathe easier with SWASATM Anti-pollution face masks developed by E-Spin Nanotech Pvt Ltd. Featuring an innovative fibre membrane, SWASATM face masks pro- vide affordable and low-cost protection from all kinds of particulate con- taminants down to 2.5 um in size, including air-borne bacteria, pollen, fumes and other irritants. These masks have been tested and certified by CE mark and ISO mark to have a bacteria filtration efficiency of 99.9% as per standards. They feature a low pressure drop, making it easier to breathe through them. These masks are reusable, lightweight, comfortable, foldable and are easy to carry. They come with adjustable nose clips and a two-strap design to provide a custom fit with a secure seal that reduces the potential for eyewear fogging.

Bacterial Filtration Efficiency (BFE) & Differential Pressure (Delta P) Report |
|
The BFE test is performed to determine the filtration efficiency of test articles by comparing the bacterial control counts upstream of the test article to the bacterial counts downstream. A suspension of Staphylococcus aureus was aerosolized using a nebulizer and delivered to the test article at a constant flow rate and fixed air pressure. The challenge delivery was maintained at 1.7 - 2.7 x 10^ colony forming units (CFU) with a mean particle size (MPS) of 3.0 ± 0.3 pm. The aerosols were drawn through a six- stage, viable particle, Andersen sampler for collection. This test method complies with ASTM F2101-14, EN 14683:2019, Annex B, and AS4381:2015.
The Delta P test is performed to determine the breathability of test articles by measuring the differential air pressure on either side of the test article using a manometer, at a constant flow rate. The Delta P test was designed to comply with EN 14683:2019, Annex C.
All test method acceptance criteria were met. Testing was performed in compliance with US FDA good manufacturing practice (GMP) regulations 21 CFR Parts 210, 211 and 820.
