Product Description

The reusable face mask contains 2 replaceable PM2.5 Activated Carbon Filters (ACF). The masks are washable, but not the filters. With the filter, the mask protects against gases, odor, pollen, haze, dust, smoke or any particulate matter with diameter of 2.5 microns(one millionth of a meter) or less (about 3% of the diameter of a  strand of hair). Respiratory droplets are at least 5 microns in diameter.

The mask will hold a PM2.5 filter made of 4 layers of high technology filtration.

The middle layer of the filter is the activated carbon filter. Activated carbon layer is super important. It was originally invented by the UK Ministry of Defense. It was then extensively developed and made into a product for use in chemical, biological and nuclear warfare protection, of the type used by armed forces around the world.

On top of the ACF layer is a layer of melt-blown cloth for extra protection and filtration. And these two layers are enclosed by the outermost layers that are made of non-woven cloth.

The pack contains one reusable washable cotton mask in black and two PM2.5 ACF filters. However, our masks/filters are not approved by FDA and therefore cannot be used in a medical setting. Medical device registration required.

The mask's adjustable wire nose bridge adjusts to each person's nasal height and shape for a tighter fit and better seal. It's stretchy and adjustable ear loops adjusts to fit most adults and children.

The mask is designed not to have the air valve feature as the air flowing outwards through the one-directional valve is not filtered. The air would escape without going through the filters. If one is sick, they could release their respiratory droplets into the public airway, which is not good for protecting others.

Who can use it?
1 mask, 2 replaceable PM2.5 filters
Each filter can be used anywhere between 1 day to 1 week, depending exposure, environment and usage
How to regenerate the ACF filters

Only reuse the filters if necessary and only reuse them a few times.

The filters can be reused through one of the following ACF regeneration processes that forces the absorbed particles to break free from ACF.

  1. Sunbathe the filter under strong sunlight.
  2. Boil the filter in water for 10-15 minutes. Rinse under running water for a few minutes to remove the particles. Dry and reuse. Avoid twisting or rubbing the filter with hands because that can damage the fiber structure and integrity. Use blow dryer on high heat to dry and to break free the absorbed particles.

Stop using the filters if the fibers become loose or worn.

Guidelines for Cloth Masks from the California Department of Public Health
  • Ideally, face coverings should be washed after each use. Dirty masks should be placed in a dedicated laundry bag or bin for temporary storage.
  • Use detergent and hot water when washing cloth masks, and dry them on a hot cycle.
  • Be sure your mask is comfortable; you don’t want to have to keep adjusting the mask, because that means touching your face.
  • Wash your hands, or use hand sanitizer, before and after touching your face or face coverings.
  • If you must wear your cloth face covering again before washing it, wash your hands immediately after putting it back on and avoid touching your face
What is PM 2.5 and how can it affect my health?

According to New York State Department of Health:

“PM2.5 refers to tiny particles or droplets in the air that are two and one half microns or less in width. Particles in the PM2.5 size range are able to travel deeply into the respiratory tract, reaching the lungs. Exposure to fine particles can cause short-term health effects such as eye, nose, throat and lung irritation, coughing, sneezing, runny nose and shortness of breath. Exposure to fine particles can also affect lung function and worsen medical conditions such as asthma and heart disease. Scientific studies have linked increases in daily PM2.5 exposure with increased respiratory and cardiovascular hospital admissions, emergency department visits and deaths. Studies also suggest that long term exposure to fine particulate matter may be associated with increased rates of chronic bronchitis, reduced lung function and increased mortality from lung cancer and heart disease. People with breathing and heart problems, children and the elderly may be particularly sensitive to PM2.5.”


PM2.5 comes primarily from automobile exhaust, off-road vehicle (e.g. construction equipment, snowmobile) exhaust and other operations that involve the burning of fuels such as wood, heating oil, coal and natural sources such as forest and grass fires. Indoor sources of PM 2.5 are tobacco smoke, cooking (e.g., frying, sautéing, and broiling), burning candles or oil lamps, and operating fireplaces and fuel-burning space heaters (e.g., kerosene heaters).


Question: Where do I insert the replaceable filters?

Answer: Insert the PM2.5 filter through the sleeve opening on the pink side of the mask. Push the filter in until it is centered inside the mask.
