Since the COVID-19 outbreak in early 2020, the world has been lacking masks-especially N95 masks worn by medical staff. Although these covers provide the highest level of protection currently available, they also have limitations.
Benefits of filter retainer in mask
With this handy filter accessory, users can combine the 3M Particle Filter 5000 Series with the 3M Gas and Vapor Filter 6000 Series for protection against suspended particles.
Features and benefits
- Widely used and suitable for all 3M full face masks and half face masks
- A cost-friendly solution for expanding respiratory protection in any environment
- Quick and easy installation on the filter
They can be reused many times on the filter element of the mask. In addition, if you do not want the filter retainer but want good results, a membrane has been developed that can be attached to a regular N95 mask and replaced when needed. The pore size of the filter is smaller than a normal N95 mask, which may block more virus particles.
The N95 mask can filter about 85% of particles smaller than 300 nm. SARS-CoV-2 (the coronavirus that causes COVID-19) has a size range of 65-125 nm, so some virus particles may slip out of these covers. Similarly, due to shortages, many healthcare workers have to wear the same N95 masks repeatedly, even if they are for one-time use.
How to choose
There are many choices for masks. Before you choose mask with filter retainer, you can choose the following types of masks with two or more layers of washable, breathable fabric.
- Choose a washable mask with two or more layers of breathable fabric;
- Choose a mask that completely covers the nose and mouth;
- Choose a mask that is close to the sides of the face and has no gaps.
Perfect tip: When you wear a mask, please close to both sides of your face, leaving no gaps; boys and girls who wear glasses due to myopia, use the nose clip when wearing them to prevent air from leaking from the top of the mask. Finally, please follow the manufacturer's instructions to properly wear, store, clean or dispose of the mask.
Another perfect tip: If you have large quantity, please cooperate with a wholesale China High Quality oem filter retainer supplier,manufacturer, wholesaler, factory who will give you favorable price.
