The size of H1N1 virus particles can vary, but generally range from about 80-120 nanometers. N95 masks are designed to filter out particles as small as 0.3 microns (300 nanometers) with an efficiency of at least 95%. Therefore, N95 masks are effective at filtering out H1N1 virus particles.
A sour smell from an N95 mask could be due to sweat and moisture buildup over time. It is important to clean and dry the mask thoroughly after each use to prevent odors and ensure proper function. If the smell persists, it may be time to replace the mask.

The respirator masks that are designated with the filter class of N95 means that the respirator filter will block at least 95% of small particles. The N refers to its properties related to oil resistance of the mask: N = Not Oil Resistant, R = Oil Resistant, P = Oil Proof
The pore size is the average 100 micrometers.
Seitz filters typically have a pore size ranging from 0.1 to 1 micron. The specific pore size will depend on the manufacturer and the intended application of the filter. It's important to select the appropriate pore size based on the particles you need to remove from the liquid.
The sides of the mask should dimple inwards when you inhale sharply. And bulge slightly when you exhale. That is for the N95 Respiraotor Masks we have here anyway.
N95 is a type of respirator mask that is recommended for healthcare workers when caring for patients with infectious diseases like H1N1 influenza. N95 masks can filter out 95% of airborne particles, including viruses, and are designed to provide a tight seal around the face to enhance protection.
If the 25 and 50um refer to the actual pore size, then the 50 would be larger pore size
It isn’t always easy to buy one or two masks and continue using them, because every mask has its own life. Wondering where to buy face masks for you and your family in bulk, preferably a little cheaper too? Simply log on to accumed and you will notice how it actually is your one-stop destination. Name the type of mask and they have it for you, in bulk and at a slightly reduced price range too.
Not if you are wearing it to protect you from viruses or other sub-microscopic pathogens or pollution/fumes. These N95 masks are more like respirators than a cloth or paper surgical mask. None of these should be reused when used for medical purposes, they should be thrown away after each use since they may harbor some of the filtered particles on the outside that could contaminate people or environments. They can not be washed for reuse, either, this will potentially deform or disintegrate the mask rendering it ineffective. N95 masks must also be medically fit to your face or they will not be effective. They are not recommended for children or those with beards or mustaches because that can allow gaps for particles to enter around the mask. See more in the related questions section.
Porosity 4 sintered glass typically has pore sizes ranging from 4 to 16 micrometers, with an average pore size of around 8 micrometers. The pore size distribution can vary depending on the specific manufacturing process and conditions used to produce the sintered glass material.
