All StyleSEAL filters are independently tested at Nelson Labs, Salt Lake City, UT, USA in compliance with US-FDA regulations 21 CFR Parts 210, 211 and 280 at a particle size of 0.3 microns.
StyleSEAL filters are replaceable, which is a lot different from disposable surgical masks or respirators. Other masks use either disposable filters thrown away after use, or non-replaceable filters. We compare our replaceable filters to both alternatives:
Disposable filters are discarded along with the nose piece and ear straps each time. As a result, the manufacturers use inferior, cheap materials that perform poorly. Since StyleSEAl, Penumbra and Umbra air masks use replaceable filters our nose piece, ear straps and fabrics can be of high quality, insuring a tight seal to the face.
Products with built-in filter do not give you the ability to evaluate the status of the filter, since you cannot see it. Also, the filter material must be cleaned along with the other parts of the mask, which is detrimental to the capability of the filter.
Cloth only masks should not be considered since cloth alone is not a filter. Fabric, in most cases, is designed to breathe so it cannot filter PM10 and PM2.5 particles. Therefore, cloth alone does not filter the small particles that will hurt you! Cloth masks merely keep the bugs out of your nose.
The filter that you select should match the highest hazard level you may encounter during your daily routine. Your hazard level can change drastically during the day based on the environment around you, your commute, workplace or school. There may be times when the various risks may be greater than normal. When the hazards increase, you should also increase your protection by increasing the filter level.
StyleSEAL has various filter levels for you to match to your current risk:
Each pair of replaceable filters are color coded with an identifier ring to correlate to the Air Quality Index (AQI). The filter efficiency increases as the risk increases, as does the price.
Below is the Air Quality Index (AQI) scale and our recommended filter chart:
Some Air Quality Index scales show the PM2.5 levels as well which are included in the chart below and in our filter recommendation chart.:
The filter recommendation chart identifies at risk people such as those sensitive to poor air quality, those with allergies, the sick or elderly, who may require a higher level of filtration.
In addition to the (4) four filtration efficiency levels you can choose to add Carbon to our 80 and 90 filters. Carbon can absorb gaseous pollutants in the air.
The major gaseous pollutants include:
The primary source of these gases is the combustion of fossil fuels in power plants, various industrial processes, and motor vehicles and equipment. Each of these pollutants, in their gaseous form, can cause harm to human health and the environment. If you are near automobile exhaust or work near chemicals such as a hairstylist or nail technician you should consider carbon additive.
Carbon filtering is a method of filtering that uses a bed of activated carbon to remove contaminants and impurities, using chemical adsorption.
Each particle/granule of carbon provides a large surface area/pore structure, allowing contaminants the maximum possible exposure to the filter media. One pound (454 g) of activated carbon contains a surface area of approximately 100 acres! Carbon can be highly effective in absorbing gaseous pollutants and odors.
Nano-silver can transform protein and amino acid expression and generate reactive oxygen species (ROS), thus damaging the DNA of germs and kill them. Thus, nano-silver can eliminate a wide range of germs without any drug resistance. It is also characterized by high efficiency and strong permeability, so is able to kill detrimental germs within several minutes. Both the 95S and 99S level filters include the nano-silver additive.
Our filters are easily installed by attaching the loop side of the filter to the hook side in the air mask, as shown below.
On the World’s Air Pollution website you can find the Air Quality Index (AQI) for every city in the world. This is a good place to start. Another tool we recommend is the AirVisual air quality app. You can install this app on our smartphone to keep track of the daily AQI readings in your area or city.
Local readings are often displayed in newspapers or local websites as well.
Download the AirVisual app and get daily notifications of the air quality in your city.
The best way to know the air quality reading in your micro-environment is to use your own portable air quality meter daily.
There is not much benefit to monitoring the Air Quality in your area, if you do not react to them. Wear your StyleSEAL Air Mask with the appropriate filters when you go outside. Even though it would be healthier, many of us just can’t stay home if the air quality is poor.
