It’s clear that wearing a facemask is going to be part of our daily lives for the foreseeable future. By now, you probably have already purchased a mask and may have a couple of extra on hand too, but not all masks are made equally. Masks can be made from different materials, have different layers, construction, have valves, no valves, a filter, no filter, be disposable, reusable, etc.— the list goes on and on.
No matter what kind of mask you have, we’re here to help you ensure that your mask is as effective as possible at protecting you from virus-carrying particles and other airborne contaminants.
How effective are masks?
Based on information from the CDC, we know that a face covering with two or more layers when worn properly is an effective way to help prevent the spread of COVID-19. Wondering if your mask is approved by the CDC? Click here.

How to make your RZ Mask more effective
Do you already own or are you considering purchasing an RZ Mesh Respirator Mask? As you probably realized, these high-quality reusable masks have valves. While these masks are extremely effective at protecting the wearer, the valves make them ineffective at preventing the spread of virus-carrying particles because they allow droplets to escape the mask that can put others nearby at risk. A growing number of counties, states, and airlines are banning these masks because they are not effective at preventing the spread.

The RZ Mask Exhalation Valve Caps are the answer to this restriction. These caps do not allow any air to pass through the valves and force your exhaled breath back through the mask filter. This design helps prevent airborne particulates and germs from escaping the mask so that your RZ mask is effective at preventing the spread.

How to clean your face mask
The key to having an effective face mask is making sure it is clean and not harboring bacteria. Many people opt for fabric or cloth face masks because you can simply throw them in the wash with your clothes for an effective clean. Others opt for disposable face masks for obvious reasons. Some masks require hand washing and others require soaking and hanging to dry. If you’re looking for an easy way to clean your mask and keep it clean, try the RZ Mask Germ-Free & Odor-Free Mask Cleanser Spray!
This safe, rinse-free mask spray can be used on any mask and will keep your mask free of odors and germs. It’s respiratory safe and is easy to use!

According to the CDC/NPPTL/NIOSH 12/15/20 update of the NPPTL Respirator Assessments to Support the COVID-19 Response > International Assessment Results – Not NIOSH-approved, the manufacturer associated with the “RZ Disposable Mask L-288”, Guangzhou Harley Commodity Company Limited, has informed NIOSH that some of the L-288 respirators are counterfeit products. Please refer to the following link provided by the CDC in the table “Respirator Assessment Results Considered as Counterfeit and/or Misuse of Company Name”:
