What are PM 2.5 Filters and How to Care for Reusable Face Masks

There is a phrase we all have been hearing a lot of lately.

”Corona-Virus has changed the world and we are never going to be the same again”.

This phrase is true in many aspects, one simple example being, many of us including myself never purchased a face mask or even heard of PM 2.5 Filters until the corona virus pandemic hit the world. This leads to many unanswered questions such as; Best Face Masks to Purchase, How often to wash Face Masks, What are PM 2.5 Filters and How to Care for PM 2.5 Filters. This article aims to answer all these common questions.


The conscience of environmental sustainability have made many people consider investing in re-usable cloth face masks instead of one use face masks. The World Health Organisation (WHO) stated in their recent guideline (July, 2020) that, cloth face masks should have at least 3 layers of fabric to offer maximum benefits. Other factors, like the type of material, design, fit, and how frequently a mask is washed, also makes a difference in the protection it can give to an individual. According to the New York Times (June, 2020) multi-layered homemade masks that were properly fitted did the best job of containing respiratory droplets, while “loosely folded face masks” and bandannas “provide minimal protection in stopping the smallest aerosolized respiratory droplets.”

So it seems not all fabric reusable face masks are created the same, and the best face masks to purchase would be three layered and properly fitted face masks.

We kept this advise in mind when creating the face masks in our face mask collection and you can buy triple layered reusable fabric face masks for ‘Next Working Day UK Delivery’ at:

What are PM 2.5 Filters & How do you care for PM 2.5 Filters

The air we breathe is invisible to the naked eye, and it carries allergens, germs, chemicals and other small particles. PM stands for ‘Fine Particles Matter or Particular Matter 2.5’. Fine particles matter (PM 2.5) are tiny particles or droplets in the air that are two and one half microns or less in width in size. This particle is also the air pollutant than can reduce the visibility in the air.

PM 2.5 Filters are made from cotton and features of thin layers of foam. The filters have 5 layers of non-woven protective cotton fabric, anti sticking cloth, activated carbon, filter cloth and foam.

PM 2.5 filters can be effective for up to 3 days with continuous use and up to 2 weeks occasional use. You cannot wash to clean PM 2.5 Filters and after these advised timelines you should throw them away. This is the reason we made the process of inserting the PM 2.5 filters inside our face masks a manual task.

Our reusable face masks have three layers of fabric and should offer you maximum benefits when worn independently of the PM 2.5 filters.

We also know that there are days you would want that extra bit of protection or confidence so we took the initiative to include complimentary PM 2.5 filters with every order.

DISCONTINUE the USE of PM 2.5 FILTERS if you notice any of the following symptoms:

Breathing difficulty
Eye irritation
Dryness of the nose and mouth
Throat infection
Feeling of Claustrophobia

How to Care for Fabric Face Mask

Hand wash Face Mask with warm water and mild detergent for at least 5 minutes and rinse thoroughly after every day of use. It is important to air dry completely before the next use.

It is best to leave the face mask in a airy area when not in use, instead of the bottom of your bag, because moisture is a breeding ground for germs.
