What exactly is an Anti-Pollution mask?

  • Anti-pollution masks filter out some of the pollutants and allergens that contaminate the air that we breathe. They are typically worn outdoors and even sometimes indoors where air quality problems exist - they include older buildings with moldy air, or outdoor air coming in containing dust, pollen or other pollutants. 
  • CUVU masks are superior to other anti-pollution masks in that they have a 2-way filtration of air through the filter chambers - both the inhaled as well as exhaled air is filtered.  This protects others from exhaled air coming from the mask user.  Other anti-pollution masks with exhalation valves do not protect others in case of a viral pandemic.

    How do CUVU masks work?

    • CUVU re-usable masks come with replaceable 3M filters rated at PM0.3, which means that they attract and capture Particulate Matter lager than 0.3 microns.  They have an electrostatic charge that captures particles three times better than non-electrostatic filters found in other filter masks. 
    • Particles larger than 0.3 microns include: Bacteria, Dust, Mold spores, Particles carrying odors, Particles carrying viruses, Pet dander, Pollen and Smoke.
    • Please note that some pathogens (bacteria and viruses) are smaller than 0.3 microns and may not be filtered.

    Why not just use a cotton/cloth mask?

    • Cloth masks and disposable masks do not protect you by filtering the air that you breathe in.
    • Cloth masks and disposable masks do not form a tight seal with your face, which allows unfiltered air in/out.

    How comfortable are CUVU masks compared to other masks?

    • We have made it a priority to create a mask that provides a great seal rivaling medical PPE masks.  The mask should be worn stretched against the face to provide full protection against environmental contaminants, ensuring that all inhaled air comes in through the filter valves.  Because of the emphasis on seal and fit, some may find that the mask creates more pressure against the face compared to lose fitting cloth as well as most "surgical-type" masks.  However, most people will adjust to the mask after some time.
    • If the mask feels uncomfortable at the beginning, we suggest wearing it slightly loser, however at no time should the mask fall off the nose - the mask should be worn such that it completely covers the nose and mouth openings at all time.

    How can I ensure a good fit with the CUVU mask?

    • CUVU masks are designed to be flexible and one-size fits all for adults with an average face size and shape.
    • Smaller-faced adults may find that the lower parts of the mask extend out from their chin area - this is normal as long as the lower part of the cheeks and chin are still in full contact with the inside of the mask.
    • The tightness of the mask can be adjusted using the adjustable straps in the back of the head.
    • The seal at the top of the mask near the nose and cheek bones is adjusted using the adjustable plastic nose bridge.
      • Simply use a blow dryer at medium heat setting to warm up the nose bridge plastic for about 15 seconds, then gently bend the plastic to the required shape for your face.  Do not use hot heat settings or perform this with the mask on your face.  Once cooled down, the nose bridge will stay in that position and will not need to be adjusted. 
      • The above process can be repeated a number of times as needed to obtain the desired fit and seal.  Do not attempt to bend the plastic without warming it up first, as it may break.

    What are the materials used in the CUVU mask?


    • Mask body: reinforced neoprene foam
    • 3M filters: melt-blown polypropylene non-woven fabric
    • Plastic accessories: vegetable-derived poly-lactic polymer
      • Copper-coloured valves and filter holders contain 20% copper powder weight by weight, blended into the polymer composition

    How do I replace the filters?

    • Take out the existing filters by removing the filter holders from the inside of the mask (twist & pull up)
    • Place the new filter fabrics over the opening and secure in place with the filter holders (twist & push in)

      What is the best way to clean/sanitize the CUVU mask?

      • Sanitizing with rubbing alcohol: use a cotton pad to gently rub minimum 70% ethyl alcohol onto the surface of the mask. You do not need to disassemble the filters for this and it's ok if you get alcohol on the filters.
      • Washing with water and soap or dish detergent: remove the filters from the mask before exposing to water. Gently wash the mask surface with soapy water and allow to air dry.  You can still use the mask if wet as well.  It's ok if the filters get wet, but we recommend that they be removed and allowed to air dry before/after use.
      • CAUTION: do not use any appliances to wash/sanitize your mask - do not use a dryer, washing machine, dishwasher or microwaves.  Do not iron or dry-clean.

      How many times can the CUVU mask be re-used?

      • You can reuse the mask many times if you use, clean and keep it with care.  In normal usage conditions there should not be any issues reusing the mask about 200 times or about 12 months, as long as the filter media is replaced regularly.

        How many times can each filter media be re-used?

        • In the age of a viral pandemic, experts agree that viruses can live on some surfaces for days. If you do decide to re-use a filter after some time, we recommend following the recommendations of health authorities.
        • As an anti-pollution mask filtering commonly found pollutants, allergens and germs, the filters can be reused a number of times depending on environmental air conditions.  It is recommended that each filter not be used more than a week or about 15 hours of total use.
          Will the filter lose its function after getting wet?
          • The electro-static force embedded in the filter media is very strong and will not lose its function after getting wet.  However, the filtration efficiency will decrease gradually if exposed repeatedly to water.  It is recommended to always remove the filter while washing the mask with water and avoid getting soap on the filters.  If the filter does get wet, remove it and allow to air dry before use.
          Are CUVU masks government approved?
          • No. CUVU masks are not for medical use that would require government approval and are for consumer-grade use only.  
          Are CUVU masks comparable to medical N95 masks?
          • No. N95 masks may have similar filtering capabilities as PM0.3 filters, but they have been tested specifically for fit and undergone regulatory approvals by various health authorities. 
          What are the precautions?
          • Do not use if you have any breathing preconditions
          • Do not use if you have any allergies against synthetic materials such as plastic polymers
          • Discontinue use if having difficulty breathing during use
          • Do not use in a medical setting where medical protective equipment is required
          • Before use, ensure filters are properly secured in the mask
          • When wearing, air leakage around the mask should be minimized by adjusting the tightness of the mask and/or the nose clip
          • The mask should cover the top of the nose to the bottom of the chin
          • Do not store your mask in a hot place, such as inside a hot car
