While no facemask can guarantee 100% prevention of exposure to any virus, HALOmask’s revolutionary HALO Nanofilter has been independently tested by Nelson Laboratories, a leading provider of microbiological and viral testing and analysis. In testing, HALO Nanofilters proved effective at capturing over 99% of airborne particulates and pathogens down to 0.1 microns. By comparison, the Covid-19 virus measures approximately 0.125 microns in diameter. Read more about our Nanotechnology filters here.

COVID-19 spreads from person to person primarily through respiratory droplets produced when an infected person coughs, sneezes or talks. Droplets can land on people who are nearby and be inhaled into the lungs. Unlike most facemasks, HALOmask not only blocks the inhalation of droplets, particles and pathogens, but also prevents the exhalation of respiratory droplets by the wearer.

Because HALOmask is not categorized as a medical device, certification by the FDA and NIOSH is not required. Medical mask certifications only apply to face masks that are single use and disposable.  

To minimize your risk of infection with COVID-19, wear your HALOmaskTM in conjunction with everyday preventive actions, including good nutrition, frequent handwashing and social distancing.  Please continue to follow the guidance and orders issued by local government authorities and workplace/institutional instructions and standards.

For maximum protection we recommend weekly replacement of filters for people in direct daily contact with the general public or people with higher-risk conditions. For regular and occasional use (such as commuting, shopping, traveling and gardening) replacing your mask filter every 2 – 4 weeks will keep it fresh and functioning efficiently.

Nanofibers are extremely small fibers – more than a thousand times thinner than a human hair, and individually invisible to the human eye. Nanofibers form dense spider web-like structures which have an advantage over conventional filters due to their incredibly large surface area and miniscule pore size.  In each HALOmask there are up to 15 miles (24 km) of nanofiber in each woven Nanofilter!  The unique structure of this ‘invisible matrix’ physically captures virtually all airborne particles and pathogens - from smoke, dust, pollution and pollen to bacteria and viruses.

The HALO Nanofilter is composed of a microscopic nanofiber matrix sealed between two layers of inert backing material. This nanofiber matrix is made up of several very, very long fibers weaved together. It's not nanofiber particles -- so there are no "pieces" that can be inhaled.

Yes! The HALOmask and nanofiber filters are tested and certified to Nelson Labs standards to 99.3% particulate efficiency at 0.1 Microns, which exceeds N95 standards. More information and test results can be found on our filters page

Mask Questions

According to recent studies, simple cloth masks and masks without filtration technology do not stop viruses or bacteria. Viruses and bacteria are thousands of times smaller than the strands of cotton or synthetic thread in home made cloth or non-filter masks, allowing airborne particles to pass directly through. Our high-tech, paper-thin HALO NanofiltersTM feature a proprietary ‘nano-matrix’ that blocks virtually all smoke, dust, pollution, pollen, particulates and pathogens.

Many conventional masks use filters with up to 4 or 5 layers. This means you have to inhale and exhale through all these layers AND the fabric of the mask with each breath, which can be hard work! This can also cause air to leak around the edges of these masks, allowing airborne particulates and pathogens to pass through unfiltered. To avoid this, some masks add valves to quickly expel air when exhaled, but these valves typically have no filtration, and thus offer no protection to others. As a result, when someone wearing a mask with a valve coughs, sneezes or breathes forcefully, bacteria and viruses can pass directly through the valve and out into the air.  For this reason many city, state and local governments across the United States have banned masks with valves.

In stark contrast, the paper-thin HALOmask Nanofilter allows the wearer to breathe freely and enjoy maximum filtration BOTH on the inhale (from the environment) and the exhale (protecting others).

Every HALOmask includes an adjustable noseband (and optional nosepad) which seals the mask around your nose and cheeks. When worn correctly, exhalation passes directly through the mask and not up into your glasses. If you experience fogging, adjust your noseband and renew your nose pad.

Sports Mesh Collection: The outer part of the mask is 80% polyester, 20% spandex for lightness, breathability and durability; and the inner is 95% bamboo and 5% spandex for comfort, antimicrobial properties, and moisture wicking.

Unity Collection: Both the outer and inner parts of the mask are 95% bamboo and 5% spandex.

The mask itself is two layers, which falls in line with CDC guidelines. Adding our nanofiber filter adds the ultimate protection.

HALOmask features a natural bamboo lining that is naturally cooling and moisture-wicking, and which is also antibacterial due to a unique ingredient called Kun that repels germs, bacteria and pathogens. This results in a mask that is super-comfortable to wear (without chafing) for hours at a time, while remaining fresher for longer between washes.

Take a look at the sizing chart that's linked on the product pages to help you determine sizing. And, when in doubt, order the smaller size -- your HALOmask has a wide range of adjustability and should cinch down to form the perfect fit.

Sizing, Fit and Care

1. Remove from packaging and unfold your mask.

2. Hold the mask up and locate the noseband in the bridge.

3. Hold the foam nosepad and peel off the backing to expose the adhesive strip.

4. Carefully fold nosepad into a V with the sticky side facing OUT

5. Insert the sticky side of the nosepad into the “V” where the nose will go into the mask.

6. Press nosepad firmly into mask for several seconds.

7. Place your mask with its flexible nose-band (and installed foam nosepad) over the bridge of your nose and gently bend to fit.

8. Pull straps over ears.  To adjust the size of the ear loops, take off the mask, hold each rubber bead in turn, and pull each strap or both together to tighten or loosen
9. Pull the mask down to wrap under your chin
10. Continue adjusting straps and noseband for maximum comfort

Making fine adjustments to your HALOmask assures the perfect fit and the best protection. Your mask is adjustable in some key ways. Please visit this page, which shows videos on sizing and fitting your HALOmask:  https://halolife.io/pages/my-new-halo-mask You can also refer to the following tips for getting the best fit:

Adjusting your ear loops
The ear loop straps have small plastic beads which you'll see on each strap. These allow you to adjust the tension on your HALOmask straps, ensuring a snug fit. The goal is to create enough tension on the straps to pull the mask snugly to your face. To make fine adjustments, first, place the HALOmask on your face. If you're tightening the right strap, use your left hand to hold the forward side of the straps before pulling the bead forwards, towards the front of your head. To loosen it, hold the back portion of the strap and slide the bead backwards. To adjust the left strap, follow this same convention.

Adjusting your noseband
This adjustment is crucial to ensuring that there are no air gaps at the top of the mask. Having a properly adjusted noseband can also help to prevent the fogging of your glasses! Make sure that the ear loops are properly adjusted before taking this step.

To adjust your noseband, place the HALOmask on your face. Using your thumb and forefinger, gently squeeze the noseband until it fits snugly around the nose. For finer adjustments, try squeezing higher or lower on the nose band.

When you take your mask off, or clean it, it is recommended that you try to leave your nose band in its adjusted position. This will ensure that your HALOmask will fit perfectly, the next time you put it on. It will also help to ensure that your HALOmask will last for a long time.

Adjusting your chin wrap
This one is the easiest adjustment of all! Your HALOmask comes with a special chin wrap, which ties all of your adjustments together. It is the icing on your perfect-fit cake. Once your ear loops and noseband have been adjusted, just make sure that your chin wrap is unfurled by gently tugging it downward. That's it!

1. Remove the filter from its package or from the mask if replacing.

2. Fill a bowl or basin with hot water, add detergent to clean and disinfect the fabric. You may add some drops of activated oils such as tea-tree, eucalyptus or lavender to further disinfect. We do not recommend chemical disinfectants or alcohol be used on this product.

3. Submerge and agitate the mask, soaking for 10 -15 minutes.

4. If stained or soiled, use a small brush with soap or detergent to spot clean

5. Rinse mask in warm water, flick excess water off and pat dry being careful to not overbend or distort the internal noseband

6. Hang in the sun or a warm airy place to dry.

7. Once dry, replace with existing or new filter

Most masks under-perform with facial hair and beards as they don’t allow for an air-tight seal around the face and neck.  HALOmask is  specially designed to wrap around your chin enables a more secure fit for every shape of face including those with beards.

Our masks actually exceed N95. However, no consumer mask, whether it be made by Halo Life, Nike, Under Armor, Guess, Nordstrom, or any other company, can attain medical-use certifications. Certifications, like those issued by the FDA or NIOSH, are reserved for other classes of masks -- like those for use in medical settings.​

Our nanofiber filter has been independently laboratory tested and verified to exceed N99 standards, handily beating N95 masks. Regardless of how much our filter and mask exceed N95, the 'non-medical' designation is required by law. If others are not using this designation, they do so in violation of the law.

At the moment, we do not have specific sizes for children. However, we do plan to have them available in the coming months! That said, please consider a small mask for your child if they fall within the guidelines on the size chart.

Because you are breathing through a filter. :-) Our exclusive 'hyperloft' nanofiber captures all airborne particulates down to a size of the smallest viruses (0.1 microns), while meeting or exceeding international standards at 1.0 microns (99.70%) and 2.5 microns (99.99%).

We always recommend you use our filters with the mask, however we also believe that any mask (even one without a filter) is better than no mask. :-) The mask itself is two layers, which falls in line with CDC guidelines.

Because HALOmask is not categorized as a medical device, certification by the FDA and NIOSH is not required. Medical mask certifications only apply to face masks that are single use and disposable.  However our proprietary filter, which we make in New Zealand recently independent laboratory-verified to have tested at N99.99, meaning that it filters at least 99% of airborne particles at .3+ micron-particles.

The nosepad is made from 100% latex rubber.
