PM2.5 filters

PM2.5 filters

PM2.5 filters are recommended for protection against airborne particulate matter, air pollution, dust and pollen allergies. These filters consist of 5 layers and combined with filter pocketed face masks, they can filter up to 95% of airborne particulates as small as 0.3 micron. This filtration is as efficient as offered by N95 respirator masks. However, face masks with replaceable PM2.5 filters can trap harmful particles exponentially longer compared to disposable masks. As a layer of these filters, absorbing power of activated carbon helps to defend your respiratory system by trapping harmful particles in it and prevents them from damaging your respiratory system. The PM2.5 filter paired with a fabric mask offers you the best of both worlds: significantly greater protection than a cloth mask alone, but with far less inhalation resistance and potential heart damage than an N95 Respirator.  Just insert one of our disposable PM2.5 filters into a pocket of your cotton mask, tighten the nose-piece, and adjust the ear straps. Because our masks are 100% cotton, they can be washed regularly to kill any living particles trapped in the fabric. The filter can be replaced once a week or depending on the frequency of use. 


5 layers of MP2.5 filters include following:


1st Layer. Anti Sticking cloth filters micron-level dust.


2nd Layer. Filter cloth traps industrial pollutants, car exhaust, second-hand smoke, paint and pollen allergies.


3rd Layer. Activated carbon filters small harmful particles which are not visible to a naked eye.


4th Layer. Filter cloth stops harmful particles as small as 0.3 micron from reaching your lungs.


5th Layer Anti Sticking cloth filters minimal airborne particulate matter such as Coronavirus, and lets you enjoy fresh air free of any harmful particles or viruses.

What is PM2.5?

The air we breathe in is full of minuscule particles such as chemicals, smoke, dust or allergens which might be in the form of gases, solids or liquids. These tiny airborne particulate matters are mostly invisible to our eye and referred to as PM. 
PM2.5 is a particulate matter with a 2.5 micrometer sized pollutant and can be seen only in a powerful microscope. Diagram provided by the Environmental Protection Agency illustrates that PM2.5 can be 20-28 times smaller than a human hair which is the smallest thing detected by a human eye.

The danger of tiny harmful particles lies not only in penetrating our respiratory system, but also entering our bloodstream because of their microscopic size.

How harmful is PM2.5? 

Miniscule particles such as PM2.5 might have long or short term negative impact on your health depending on how strong your immune system is. The most common harmful effects of this hazardous airborne particulate on humans are:

  • Throat, nose and eye irritation

  • Difficulty breathing

  • Continuous coughing and sneezing

  • Declining lung function

  • Development of lung diseases

  • Deterioration in heart function

  • Risk of heart attack

  • Asthma

  • Fatal outcome

What protection is available from miniscule particulates?

Maintaining good hygiene, washing hands, staying indoors and keeping social distance might limit exposure to airborne particulates but will not eliminate the risks associated with breathing harmful microparticles or Covid-19. Wearing a handmade cotton mask or disposable surgical mask will not be effective as they lack protective filters to trap microparticles. 


Combining handmade face masks prepared from double layered tightly woven 100% organic cotton with inserted replaceable PM2.5 filters offers effective protection against pollutants, viruses and bacteria. Our Olson masks come in 3 different sizes with adjustable nose bridge and adjustable elastic ear bands. Protect yourself and your loved ones from any harmful microparticles with our proudly Australian made masks. 


Stay Safe!
