To select the right filters, simply look at the Air Quality Index (AQI) in your area and choose filters with the same color. For example, if the AQI is red, use red filters. You can easily keep track of the air quality by using the AirVisual app.
Be aware that higher filter levels are harder to breathe through and more expensive. Therefore, don’t use a higher level than you need. Even the lower filter levels provide plenty of protection. The difference in protection between the filter levels is only 5%.
The filters come in a version with active carbon. We recommend you use carbon filters if you live in a city with heavy traffic. The carbon filters help to protect you from toxic gasses, such as traffic exhaust fumes and ozone.
If you need protection against airborne bacteria and viruses, choose 80S, 90S, 95S or 99S filters. These are treated with a medical grade nano-silver coating that helps eliminate bacteria and viruses. Read more about our filters here.
How often you need to change the filters depend on how much you use them. We recommend you change them after 30 hours of use.
Also change filters if they get wet, look very dirty or are difficult to breathe through.
Even though a filter may look clean, water can condense in the filter and can result in the growth of bacteria or mold. For this reason, always change the filters every 2 weeks as a minimum.
As the filters get clogged with pollution they become harder to breathe through. You can usually see this, as the filters become increasingly grey. Fresh filters are easier to breathe through and provide higher protection.
Activated carbon is carbon that has been treated with oxygen; this causes millions of tiny pores to open up on the carbon’s surface. Once carbon has been activated, it can absorb and remove many chemicals from the air, including the main gas-based pollutants:
Carbon monoxide (CO)
Sulfur dioxide (SO2)
Nitrogen dioxide (NO2)
Ordinary particle filters without carbon cannot absorb gasses. On the other hand, carbon cannot filter particle pollution (PM2.5). This is why a combination of particle and carbon filters work best, such as the STYLESEAL 80+CARBON, 90+CARBON, 95+CARBON and 99+CARBON filters.
Carbon filters are especially useful in city environments, where there are a lot of traffic exhaust, and other chemical fumes. Carbon filters also help remove smells and odors which can make breathing more pleasant.
Using a face mask will block most droplets from other people’s sneezes and coughs from entering your mouth and nose, according to infectious disease experts. Coronaviruses are primarily spread through droplets.
Be sure to use a mask that fits and seals well. Because surgical masks aren’t fitted or sealed, they leave gaps around the mouth, so you’re not filtering all of the air that comes in. Also, don’t touch your face under the mask, and avoid taking it off when talking or making a phone call.
For best protection, choose STYLESEAL 90S-Orange, 95S-Red or 99S-Purple filters, which blocks particles down to 0.1 microns and are treated with a nano-silver coating that kills bacteria and viruses.
If you are infected with a virus, close the valve outlet on the inside of the mask with our ValveSEAL stickers, or use a mask with no valve, to minimize the spread of the virus.
Be aware that no mask can guarantee 100% protection against infections. We recommend everyone practice social distancing and safe hygiene.
Your STYLESEAL mask can be washed in hand, but not in a washing machine. Use regular soap or detergent, and wash gently. Avoid rubbing or scrubbing the materials together. The masks are made of fine fabrics and designed to be lightweight and comfortable to wear.
We recommend you wash your mask every time you change the filters. To clean your mask, simply:
1. Remove the old filters
2. Gently hand wash the mask in soap water
3. Rinse in plain water
4. Hang to dry
5. Replace with new filters
Some people ask if they can use alcohol spray on the mask. If you do so, it’s important to not spray on the inside, as this could loosen the glue that hold the Velcro rings for the filters. We generally recommend using soap water as the best way of cleaning the mask.
The Air Quality Index (AQI) in an index used for reporting air quality. It tells you how polluted the air is on a scale from 0-500.
The index is divided into 6 levels, color-coded green to maroon. The higher the pollution level, the more damaging it is to your health.
An estimated 92 percent of the world’s population live in areas with dangerous levels of air pollution and scientists warn that air pollution is now a bigger threat to health than smoking. According to the latest estimate, 8.8 million people die every year from exposure to air pollution.
Air pollution may damage children’s brain development, and pneumonia, which kills almost 1 million children under the age of 5 every year, is associated with air pollution. Children who breathe in higher levels of pollutants also face a greater risk of short-term respiratory infections and lung damage.
Pollutants can affect cardiovascular health by hardening the arteries and increase the risk of heart attack and strokes, and there is even emerging evidence that air pollution may be linked to mental health conditions and degenerative brain diseases such as Alzheimer’s disease, Parkinson’s disease and schizophrenia.
Yes, according to the WHO, air pollution causes cancer. Scientists have known for years that air pollution can lead to lung cancer, but new evidence shows it can also cause other cancers, including breast, liver and pancreatic cancer. A new study found that air pollution even increases the risk of getting mouth cancer.
One study revealed that every time the concentration of PM2.5 rises 10 microgram per cubic meter (µg/m3), the risk of dying from cancer increases by 22%.
But exactly how does air pollution cause cancer? Pollution may cause flaws in the function of DNA repair, changes in the immune response of the body, or inflammation that causes angiogenesis, the development of fresh blood vessels that allow tumors to spread.
Yes, they are. At least three scientific studies have looked at the effectiveness of face masks for protecting against air pollution. One study found that face masks filter between 14% and 96% of PM2.5, depending on the brand and type of mask. The average filtering capability of all the masks was 48%.
Another study revealed that most face masks are effective at filtering pollution, but vary significantly in how much they leak. The leak inside the masks varied between 3% and 68%, again depending on brand and model. The researchers concluded that the most important factor for mask effectiveness is how well the mask fit the face and is able to seal off particles.
A third study compared regular particle filtering masks with masks that included active carbon layers. Results showed that face masks with active carbon are more effective than regular masks at filtering toxic gasses, such as nitrogen and sulfur dioxide.
All STYLESEAL filters are independently tested at Nelson Labs, USA and conforms to the ASTM F2100 standard at a particle size of 0.1 microns.
See our lab test results here.
An exhalation valve is a one-way vent installed on higher end face masks and respirators. Its function is to allow easier breathing, prevent humidity and reduce uncomfortable heat and CO2 (carbon dioxide) buildup inside the mask. A face mask with an exhaust valve will feel more comfortable and less hot than a mask without a valve.
The CO2 in the exhaled air is nearly 100 times that of inhaled air, and this can increase even further during strenuous activity. This means having an exhalation valve is especially important when you are exercising.
