What is a Face Mask?

Face Masks typically fall into one of two categories - Simple cloth type or Medical grade. Both variants offer different levels of protection against the transmission of bacteria and Airborne Pathogens. They are applied for a wide range of issues and are often used by travelers, cyclists, urban residents and respiratory disease sufferers.

Wearing the correct size Face Mask with a good fit is imperative to ensuring high level of protection for lungs.... A Good Fit is also an issue with many Face Masks. They tend to leak air as they do not fit tightly to the face. This is due to presence of gaps around the face sealing points and on the peripheries. The curvature between the nose and cheek is definitely an area from where air escapes. This allows for polluted air to get inside. The constant exhaling of air into the mask also causes us to re-inhale bad breath with bad odour. In addition, the moisture from constant exhaling inside the mask and warm human body temperature of 37 deg Celsius or 98.4 deg Fahrenheit, becomes an ideal place for viruses and bacteria to thrive.

Face Masks have a tendency to cover the face making it difficult to eat, drink or have a conversation on the phone. This causes a huge inconvenience to the wearer and causes irritation due to perspiration from wearing for long hours.

Is there a Nose Mask? What is a Nose Mask?

Nose Mask or Nasal Filter is a device that does the work of filtering the air entering through our Nasal Passages (Medical Term: Nares). Its primary aim is to help filter out the air directly from within our nostrils without having to cover our faces. A Nose Mask or Nasal Filter gives no trouble in talking, eating, drinking etc and one finally feels liberated from bulky Face Masks and feeling sweaty while wearing those, especially in the peak summer months. Unlike Face Masks’ theory of one size fits all (which maybe a bit presumptuous considering every individual has a different face cut and size); Nasal Filters come in various sizes and should be selected based on how it fits an individual’s nose shape so as to fit perfectly.

Nose Masks are available for all your needs - there are Industrial Use Nose Masks, Nose Masks for Pollution and Nose Masks for Dust. Clenare Nose Masks are available online with Different Replacement Filters to choose a per a user's convenience.

Research has shown that use of Nasal filters can bring targeted relief in case of breathing problems in comparison to the other general products available in the market. They have been tested to highest performance standards of filtration.

Even though Face Masks and Nose Masks are different products, they both are designed to reduce and prevent the user’s exposure to airborne contaminants. But if we have to go deeper into comparison, we can say that Face Mask test standards cannot be applied to Nasal Filters. The equipment and machines which test Masks cannot be used on Nasal Filters.

What are Clenare Nasal Filters / Nose Masks?

Clenare Nasal Filters are discrete and almost invisible nose air filters that work like Invisible Face Masks. They purify air that is breathed through the nose and they are so difficult to spot that they are almost invisible. They sit right into the Nasal Passages (Nares) and don’t allow pollution, dust and allergies to go into our respiratory system, keeping our lungs and thereby our heart healthy. When at home or going out, Clenare Nasal Filters keep us protected at all times from airborne hazards.

Most Face Mask use celluloid or polypropylene plastic fabrics whereas the Clenare Nasal Filter / Nose Mask is made of Special Electrostatic Nano Fiber Materials, to provide the most efficient filtration of bacteria.

Clenare Nasal Filters block particles down to size PM0.3 & PM0.1 and also have the benefit of blocking many microbes including bacteria and viruses which can be of variable sizes.

For PM10 - 97%

For PM2.5 - 90%

For Gases - 23%


Q & A on Nose Masks / Nasal Filters:


Do Nasal Filters work?

Once the air you breathe enters your nose, the Filtration process starts through the Nasal Filters and immediately start restricting Air pollutants like PM2.5, PM10, Allergies and Dust, ensuring that you are get clean air. They work perfectly well and their long term benefits become more and more evident with time.

How do you use a nose filter?

Choose your nose type and your nasal filter size with the help of the ordering chart (Image No. 4 on product page). Ensure Clean Hands and Hold the nasal filter left and right housings with the index finger and the thumb. Ensure that the U-shape connecting band is facing down when you are about to wear. Insert the nasal filter into your nostrils. Use the thumbs to push it in on both nostrils and ensure it fits correctly inside.

What is the best pollution mask?

Nose Masks or Nasal Filters are a Novel way for protecting yourself from the ill effects of air pollution. They help in filtering out the air directly from within our nostrils without having to cover our faces.

What is the purpose of a nose filter?

A nose filter is designed to fit inside the human nostrils to prevent the nasal inhalation of allergens, pollutants and irritants such as dust, smoke and foul odours.

Can Face Masks or Nose Masks prevent allergies?

Face Masks and Nasal Filters / Nose Masks work similarly in the case of indoor pollutants and allergies. The filters trap tiny particles like pollen, plant spores, pet dander, mold, house dust and dust mites. People who are sensitive to outdoor allergies may have to wear a Nasal Filter at all times including gardening, vacuuming, jogging, bicycling etc.

Can I sleep with a dust mask on?

We do not recommend wearing a Face Mask or Nasal Filters while sleeping as it can have certain ill effects or even result in accidental ejection and choking. Ideally they should be worn

What is the difference between N95, N99 / N100 and Nasal Filter?

The difference between N95 and N100 masks is simply the filter’s efficiency level. N95 filters 95% of particulates and N99 filters 99% of particulates on the air. The higher the efficiency, the more particulates the respirator will filter out and the healthier air we breathe.

Nasal Filters are capable of blocking particles down to size PM0.3 & PM0.1 including many microbes like bacteria and viruses which can be of variable sizes. They do these directly at the Main Respiratory organ of the Human Body - The Nose.
