Features & Performance Data:
- Provides improved comfort: Standard fluffed masks are substantially less comfortable to wear. The silky inner facing layer of Adenna masks effectively bonds together with the fluffed surface fibers of the inner layer, which help reduce itchiness and discomfort during extended wear.
- Provides better shape and exact fit: Unique four-fold design helps to form a cone-like shape, providing exact fit and better protection.
- Latex, fiberglass, irritant and odor free
- Particle Filtration Efficiency (PFE): > 99% at 0.1 micron
- Differential Pressure, Delta P (Breathability): < 2.0 mm H20
- Bacterial Filtration Efficiency (BFE): > 99% at 3 micron
Construction and Materials:
- Outer Layer: 28-30 g/sm fluid resistant Spunbond Polypropylene fiber
- Middle Layer (Filter): 22-25 g/sm meltblown filtration fiber
- Inner Layer: 20 g/sm silk-like ultra-soft cellulosic fiber for sensitive skin
- Ear Loop: 16.5 cm of length, 100% Latex free
- Nose Bridge: Full-length pliable aluminum nosepiece concealed by PVC material
More Information Regarding Performance Data of Face Masks
Filtration Value
The percentage of particles of a certain size, filtered out by a mask. This is determined by a mask's filtration material and its pore size in microns. A mask that filters out a higher percentage of small particles is more protective. It is important to know both the % of particles filtered and the size of the particles. Two terms used to describe these values are Bacterial Filtration Efficiency (BFE) and Particle Filtration Efficiency (PFE).
What is "Particle Filtration Efficiency" (PFE)?
The percentage of particles filtered out (do not pass through) at a pore size of 0.1 – 1 micron.
What is "Bacterial Filtration Efficiency" (BFE)?
BFE measures the filtration efficiency of a mask using viable (live) particles (bacteria) that vary in size from 1 micron to 5 microns.
Which is better - a higher BFE or PFE rating?
A higher PFE rating is more preferable. The micron particle size is no larger than 1.0 micron, thereby providing the wearer with increased protection.
Which is more important - BFE/PFE rating or micron particle size?
Both. A mask with a BFE rating of 99% at 3.0 microns may provide less protection than a mask with a PFE of 98% at 1.0 micron. Do not be misled by a high BFE/PFE rating without knowing the micron particle size upon which both are based.
What is Delta P in relation to face masks?
The Differential Pressure (DP) is a test that measures how easily air is passed from one side of the mask to the other. This indicates how easily the wearer can breathe through the mask, and is indicated by Delta P. Higher differential pressure indicates air is more difficult to push through. This could result in a "blow-by" effect (escape of air, and contamination from the sides of an improperly worn mask), or even incorrect use by the wearer.
Fluid Resistance
Fluid resistance is one of the most important features of a mask. When masks become saturated from both inside and outside, “wicking” or the rapid transfer of substances through the mask is likely to occur. High fluid resistance means better, longer lasting masks.
Adenna 4-Fold Fluid Resistant Earloop Face Masks offer a dependable solution in applications whereby maximum coverage is preferred. These masks are 100% latex and fiberglass free, as well as non-irritant and odorless. The unique consealed PVC nose piece conforms to your face better for a more comfortable wear, and minimizes x-ray reflection. These face masks are available single boxes of 50 face masks, or in cases containing 12 boxes (600 face masks total).
