About Our Product

RS1 Particle Mask is designed to help protect the wearer against inhaling airborne particulates. Airborne particulates are solids or liquids suspended in breathable air and can be classified as dusts, mists or fumes. Inhaling airborne particulates may have an inverse effect on health and, depending on the particulate inhaled, this effect may be irreversible. A well fitted RS1 mask will help protect against fine toxic particulates including asbestos, bacteria, and viruses. 

RS1 vs N95

N95 masks protect by capturing particles with an exposed filter. The accumulation of particles on the external surface of the respirator may be an exposure hazard from contact with the filter, including becoming a fomite for infectious agents. Users should be cautious and follow appropriate procedures to avoid self-inoculation from contact with these surfaces.

N95 masks are disposable and 5% of the virus gets through the mask. 

RS1 Particle masks help protect by capturing particles with an enclosed filter that cannot be easily touched. RS1 Particle masks are a practical alternative for Pandemic / Quarantine situations.

RS1 Mask are reusable. The higher the efficiency, the more particulates the respirator will filter out. The filter helps protect persons by trapping bacteria and viruses. It features high quality construction.

Shelf Life/Cleaning Instructions

FDA recognizes that, when alternatives, such as FDA-cleared masks or respirators, are unavailable, individuals, including healthcare professionals, might improvise PPE.

FDA does not intend to object to individuals’ distribution and use of improvised PPE when no alternatives, such as FDA-cleared masks or respirators, are available. For the purposes of this guidance, the following definitions are used. Face Mask – A mask that covers the user’s nose and mouth and may or may not meet fluid barrier or filtration efficiency levels.


Finally, FDA explicitly states in the policy that it does not intend to object to the manufacture, distribution, and use of improvised masks or other PPE when FDA-cleared masks and respirators are unavailable.
It is not for occupational use in workplaces regulated by OSHA except for voluntary use . This mask contains no components made from natural rubber latex.

Clean mask with soap and water…..Filter cannot be cleaned……RS1 Particle Mask may be replaced when visible dirt on filter appears or breathing becomes difficult.

RS1 Particle Mask is not invasive and cannot be hooked up to oxygen. No O2 hookup ports. Indication for Use: Help protect the wearer against inhaling airborne particulates. (No Mandatory use filtering face-piece mask).

How does OSHA define a filtering face-piece mask?

A filtering face-piece respirator is defined in 29 CFR 1910.134(b) as "a negative pressure particulate respirator with a filter as an integral part of the face-piece. An N95 mask has an approximate shelf life of 3 years.

Additional Information For First Responders & Hospitals

RS1 Particle Mask is effective in outdoor raining conditions!

All exposed material filter masks (N95 etc…) are not effective in outdoor raining conditions!

First Responders working in outdoor raining conditions (Police, EMT’s and Firefighters) need a product that is effective in outdoor raining conditions!

Occupational Safety & Health Administration (OSHA) states DON'T wear if wet or soiled, get a new N95 respirator. 

FDA, CDC Response to Supply Shortages

📷 NEWSLINE Mar 31, 2020 || Emily SchweichCDC COVID-19 patient safety

Amid nationwide personal protective equipment (PPE) shortages, the Food and Drug Administration (FDA) announced it will not levy penalties for distributing and using improvised face masks when FDA-cleared masks or respirators are unavailable.

This guidance comes as volunteers offer to create face masks for health care providers.

FDA also has issued 16 emergency use authorizations (EUAs) during the COVID-19 public health emergency, enabling the use of unapproved medical products or unapproved uses of approved medical products. Notably, FDA authorized the emergency use of ventilators, anesthesia gas machines modified for use as ventilators, ventilator tubing connectors, and ventilator accessories. Another EUA authorizes the use of respirators not approved by the National Institute for Occupational Safety and Health (NIOSH). The agency issued a frequently asked questions document about using respirators not approved by NIOSH.To help health care providers optimize PPE, the Centers for Disease Control and Prevention developed a PPE burn rate calculator. The tool prompts users to enter the number of full boxes of each type of PPE in stock and calculates the average consumption rate.

Laboratory and In House Testing RS1 Particle Mask In House Testing: Four subjects had measurements of their baseline heart rate and carbon dioxide level. Each subject then donned the device, performed a seal check and wore the device for 60 minutes continuously. Measurements were repeated at 5 and 20 minute intervals. There were no significant changes from baseline over time in heart rate and carbon dioxide level. Subjects were walking, seated and conversational throughout the testing.

Laboratory Testing:

Stockpiling advantage

No re-stockpiling until usage
Fabric Mask Material:
Fabric mask material (N95) worn longer than 20 minutes in an aerosol environment lose their protective quality and allow microorganisms to penetrate through wet material by a process called "wicking" so fabric mask material should be changed every 20 minutes during procedures that generate heavy fluid exposure or contact with wearer's nostrils or lips.
RS1 Particle Mask:
RS1 Particle Mask quarantines bacteria and viruses in an enclosed filter housing. Wicking process cannot occur on plastic mask.

True to your words the RS1 respirator masks were great and the few persons who used the masks stated that they have never used anything compared to it.
Everyone who had them on said they breathed with ease. The fact that they are actually reusable placed them all the way to the top of the list when compared to other respirator masks.
