Set of 2 Refills- Five layer activated carbon charcoal fill. The mask itself is machine washable and should last years.
The filters are 5 layers with activated carbon. I would change these out using your judgement for standards of personal hygiene. The Activated Carbon filter is a very important filter in purifier systems, but it can only last for a short time. Typical Activated carbon filter can only last between two and four weeks, then you need to launder before using it again. The Activated Carbon filter needs to be changed every few month to be efficient. This is because of the adsorption process that increasingly fill up the pollutants inside the activated carbon bed. Once the bed is saturated, the filter can no longer be capable of taking in more pollutants.
Can Activated Carbon be reused? The simple answer is yes, because of the porous nature of activated carbon. However, you can only reuse the Activated Carbon filter two to the maximum of three times, then you must replace the carbon filter so it can work against the smoke, odors and chemicals.
How to clean my filter:
If you have a sanitizer setting on your laundry machine use that. If not, Soak the filter in hot (just short of boiling water) in a pot of water on the stove for 3 minutes. Then toss in the laundry machine. DO NOT use fabric softener! Discard if used.
Machine dry on low heat and then set in direct sunlight for 2-3 hours before use. -NO GUARANTEES or testing REGARDING COVID-19.
FAQ Carbon filters:
Activated carbon filters are small pieces of carbon, typically in granular or powdered block form, that have been treated to be extremely porous. It is so cavernous, in fact, that just one gram of activated carbon can easily have a surface area of 500m2 or higher. Vast surface area enables these carbon filters to adsorb exponentially more contaminants and allergens than traditional carbon.
Adsorption is a distinct process where organic compounds in the air, water or liquid react chemically with the activated carbon, which causes them to stick to the filter. The more porous the activated carbon is, the more contaminants it will capture. These filters are most notably used to remove hazardous compounds in home air purification systems.
How Would I Benefit From an Activated Carbon Filter?
There are many benefits associated with using activated carbon filters. These purifiers can be used to rid your air of unwanted or harmful contaminants that can pose a hazard to your health.
Activated carbon filters are know to filter:
Carbon filters also help eliminate unpleasant odors. activated carbon filters can trap 99.97% of small particles 0.3 microns and higher as well as most larger particles, especially spores. Activated carbon filters can particularly benefit people who suffer allergies or aggravation from impure air, including second hand smoke. If you are or live with a smoker, using an activated carbon filter can provide unparalleled benefits to your respiratory health.
Are all Activated Carbon Filters the Same?
All activated carbon filters remove a significantly higher amount of air pollutants than regular carbon filters, however there are some distinctions. Some filters contain more activated carbon than others, and this can affect the capacity for impurity removal. The more activated carbon in a filter, the more contaminants it will catch and the faster it will adsorb.
Additionally, high levels of activated carbon increase a filter’s lifetime. It will require fewer replacements and keep emitting fresh air longer. Another factor that influences filtering rate is the size of activated carbon particles.
Typically, smaller particles yield faster adsorption rates. The most advanced activated carbon filter can be used alone or in conjunction with other filters to significantly reduce the amount of impurities you breathe in.
Our activated carbon filter has been combined with a medical grade breathable material for a total of 5 layers of filter protection. When combined with 100% Cotton fabric masks & pleats you have more than 7 layers of filtered protection for your face.
