Adjusting the Fit
The VisiGuard® Face Shield is a revolutionary new product, primarily developed in response to the Covid-19 pandemic. The new line is an effective addition to your personal protection equipment (PPE) and will continue to be of service long after the pandemic subsides. One of the many benefits of the VisiGuard® Face Shield is it's ability to fit everyone. Here we share a couple of techniques on how to adjust to a fit that you find comfortable.
First secure one end of the strap by threading the rubber band through the hole on one side of the shield and hook the loop over the nub (Figure A). Pull the strap through the hole on the opposite side (Figure B), estimating how much to pull through for a comfortable fit. Allow for the stretch in the rubber band and then tie a knot like you tie a balloon (Figure C).

Pull the band through the hole, (Figure A) loop it around the tab and back through the hole (Figure B) and then put the band over the tab (Figure C).

Aptly defined as disposable, the VisiGuard® Face Shield may imply a one-time use to some, while to others there may be value in multiple uses of one shield. Especially in the times of the Covid-19 pandemic when supplies can run short, you may want to clean the face shield. The VisiGuard® Face Shield has been independently approved by the Infectious Disease Control Department of a major U.S. hospital system for in-hospital use. Here are a few tips that we hope you find helpful. And remember, the face shield is 100% recyclable!
VisiGuard® Face Shields are made from PET, which passed ANSI Z87.1 D3 for splash and droplet protection. In addition, results of our in-house testing determined that repeated cleaning of a shield does not produce any degradation. The cleaning solutions used are commonly found in local stores. The recommended cleaners in order of preference are:
- Isopropyl Alcohol 70%
- Lysol Spray
- Hydrogen Peroxide 3%
- Bleach 5% solution
When utilizing an absorbent paper towel or lint free cloth, the shield can be wiped clean with no evidence of scratching. It was noted that bleach does leave a residue that must be wiped off, almost buffed to a polish, to remove any haze. Additional testing was completed using Ammonia (Windex) which works well to clean the shield from dirt, smudges, etc., but does not disinfect. Aerosolized Lysol is probably the most convenient disinfectant to use due to availability, but it takes a little more effort to remove a slight haze that it leaves behind when compared to Isopropyl or Hydrogen Peroxide.
It is worth noting that consideration should be given to the type of residue to be in removed. For example, bodily fluid or food processing residues can be cleaned as noted above. However, debris such as garden soil or splatter from oil drilling are likely to contain contaminants that are capable of scratching. We recommend rinsing your VisiGuard® first before cleaning, if it is soiled.
Why Anti-Fog Coatings Are Not Necessary for VisiGuard® Face Shields
VisiGuard® Face Shields serve primarily to protect from splash and droplets, although their unique design gives way to multi-functional protection. The shields can be worn with or without a face mask. We've often heard how hot a face mask can be, especially when worn for hours at a time. The VisiGuard® Face Shield is unique in that it has a self-venting feature that allows for air flow from all sides, relieving some discomfort and preventing fogging while still passing ANSI Z87.1 D3 for splash and droplet protection.
Many face shields on the market feature an anti-fog coating, which increases the cost of the face shield. In addition, the spray-on coating is very likely to leave permanent tiny droplets on the shields. Finally, the anti-fog coating often-times scratches easily when cleaned.
Use only as a face shield to protect against fluid splashing or spattering. Not intended as protection from airborne particulates. This face shield has not been cleared for medical use by the U.S. Food and Drug Administration. This face shield has not been evaluated for protection from, or the prevention of, any diseases or infections or for any reduction in the risk of exposure to a virus, bacteria or fungi. The straps contain natural rubber latex, which may cause allergic reactions.
