Always tested after 100 washes
Filtration particles (droplets from 0.8 µm): 99,4 % (EN 14683: 2019 IIR*)
Breathability (differential pressure): 44 Pa/cm2 or 4,4 mmH2O/cm2 (EN 14683: 2019 IIR*) : 4 to 6 times more breathable than average N95/ FFP2
Liquid resistance penetration test: Compliant IIR Type with 31 resistant masks out of 32 at a pressure of 16,0 kPa (equivalency: ASTM Level 3 – 160 mmHg)
*The European standard, EN 14683:2019 is for masks for medical use (surgical & procedural). The ë TECH mask meets all Class I medical device requirements for level IIR up to 100 cares.
**ASTM F3502-21 test is performed on whole devices (masks) using NaCl particles at a flow rate of 85 LPM. (as NIOSH)
***If it is tied behind the head, pre-tests in an accredited laboratory have shown that the ë TECH has a performance that meets the requirements of standard EN 149: 2009 FFP1 and is 4% of being FFP2, even after 100 cares.
The ASTM F2100 equivalency for ë TECH is Class I, Level 3 for filtration and breathability and Level 3 for synthetic blood splash resistance.
IMPORTANT NOTICE: ASTM F2100 standard has made recent changes (2023) for fine filtration (F2299). Requierements and test method are modified. Please go see what’s all about in our FAQ.
TESTED in ISO 17025 CERTIFIED laboratories
Proudly created and manufactured in Canada
When worn out after personal use, mail the mask to us or put it in a dedicated collection box for 100 % recycling. Our plastic accessories are made with recycled polypropylene from our fabric scraps. The nasal strips are returned to us for reuse in production.
Dry heat maintenance:
Machine wash or dry heat before each use.
Combinations of both disinfection modes are possible as well (e.g. 1 machine wash every 5 dry heats ).
Unlike disposable masks that must be changed every 4 hours maximum, the efficiency of etrëma masks does not decrease with the duration of use, no need to change them during the day. In workplaces, they must be washed daily for hygiene reasons.
The inner tracking labels allow to manually or digitally record the number of washes. Every mask has a unique numeric device identifier (UDI) which allows for easy traceability.
