What You'll Learn
N95 masks are popular in Delhi, but they cannot be washed
In Delhi, where pollution levels are abysmally high, N95 masks are a popular choice for protection against harmful airborne particles. However, one of the limitations of N95 masks is that they cannot be washed.
N95 masks, also known as filtering facepiece respirators, are designed to filter out 95% to 99.5% of airborne particles. They are made from a special polymer that blocks the particles from creating a microscopic film. While these masks offer excellent protection, their filtration capabilities can be compromised if washed.
The U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) advise against washing N95 masks. Washing can damage the mask's filtration system, reducing its effectiveness in filtering out harmful particles. Moisture from washing can also promote the growth of microorganisms on the mask's surface, further compromising its integrity.
Instead of washing N95 masks, it is recommended to prioritize proper handling, storage, and disposal. In situations of limited supply, alternative decontamination methods can be considered, such as vaporized hydrogen peroxide or UV-C light exposure, but only after consulting official guidelines and experts.
Some people in Delhi recommend using air purifiers for homes, cars, and offices to combat pollution. However, others argue that no mask can truly protect against air pollution, and a gas mask may be necessary for effective protection.
While N95 masks offer a sense of security, their effectiveness diminishes if they are not properly handled, stored, and disposed of or decontaminated using approved methods in times of shortage. It is crucial to follow official guidelines and consult experts to ensure the safety and integrity of these masks.

KN95 masks are also an option and can be reused
The air pollution in Delhi is a serious issue, with abnormally high levels of pollution that can affect the lungs and result in coughs, colds, fever, and frequent sneezing. To protect against the harmful effects of air pollution, it is recommended to wear a face mask that covers the mouth and nose, which are the main entry points for pollutants.
While N95 masks are commonly recommended for protection against pollution, KN95 masks are also an option and can be reused. KN95 masks are effective in filtering out particles and providing protection against fine particulate matter and pollutants. They are designed to filter out at least 95% of airborne particles, offering strong protection for individuals with respiratory issues, children, the elderly, and those with extended outdoor exposure during severe pollution.
KN95 masks can be reused for a certain period before they need to be replaced. It is important to avoid washing the masks as it can compromise their filtering ability. Instead, it is recommended to air dry them between uses. By rotating and drying out the masks, they can be reused multiple times before disposal.
When using KN95 masks, it is crucial to ensure a good seal. A proper fit ensures that unfiltered air is not inhaled, maximizing the mask's effectiveness. Additionally, KN95 masks should not get wet as it can reduce their filtering efficiency. It is advised to replace the mask if it gets wet or if the breathing resistance increases significantly.
While KN95 masks offer significant protection against particulate pollution, they may not be suitable for all situations. They are not rated for protection against gaseous pollutants or oil-based particles. In industrial settings or areas with specific pollutants, other types of masks, such as P95 or R95 masks, may be more appropriate.

P2 or P3 masks are resistant to oil
In Delhi, people are facing abnormally high levels of pollution. The air quality index (AQI) often averages 200-300+ in winters. To combat this, many residents are turning to masks for protection. One popular option is the OxiClear N99 Anti-Pollution Face Mask, which features a headband design that reduces ear strain. Other masks that have been recommended include the N95 and KN95 masks, which are known for their reusability. However, it is important to note that these masks are not to be washed as it compromises their filters and renders them ineffective.
In terms of P2 and P3 masks, they are indeed resistant to oil. P2 masks are a type of respiratory filter that protects against mechanically and thermally generated particles. They are rated to filter out at least 94% of airborne particles. P3 masks, on the other hand, offer even greater protection and are suitable for use with full-face respirators. They are recommended when dealing with highly toxic dust, smoke, mist, and chemical fumes.
The P2 and P3 ratings are part of the AS/NZS1716 standards used in Australia and New Zealand. These masks are designed to protect against a range of airborne hazards, including dust, powders, and aerosols. It is important to note that the effectiveness of any mask, including P2 and P3 masks, can be compromised by facial hair, so a tight fit is crucial to ensuring maximum protection.
When choosing a mask, it is essential to consider the specific hazards present in your environment and select a mask that offers an appropriate level of protection. For example, if you are in an area with high levels of pollution like Delhi, a P2 or P3 mask could be a suitable option to protect against particulate matter and other airborne contaminants. However, it is always recommended to consult official guidelines and professionals for specific recommendations and fit testing to ensure the highest level of protection.

Cloth masks are comfortable and reusable but offer limited protection
While cloth masks are comfortable and can be reused, they offer limited protection against pollution. Cloth masks generally offer lower levels of protection compared to other types of masks. Their effectiveness can vary depending on the size of the virus particles and the fit of the mask. A good fit is crucial to maximising the protection offered by a mask, and gaps can allow air to leak in and out. Cloth masks have been found to be less effective than surgical masks and disposable masks, which offer superior filtration.
In the context of the high levels of pollution in Delhi, residents are seeking recommendations for masks that can provide effective protection. N95 and KN95 masks are often suggested for their ability to filter out particulate pollution. However, it is important to note that disposable masks should not be washed as it can compromise their electrostatic charge and reduce their effectiveness. Reusable options, such as the ChicoBag Reusable Three-Layered Cloth Mask, are available and offer a good alternative for those seeking comfort and breathability.
While cloth masks may be more comfortable and eco-friendly due to their reusability, their protection against pollution is limited. They are less effective than surgical masks and disposable masks with higher filtration efficiency, such as N95 and KN95 masks. It is worth noting that even N95 masks are not specifically rated for pollution, but they can still provide some relief from bushfire smoke.
The level of protection offered by a mask depends on its design, fit, and filtration capabilities. Cloth masks may be more comfortable and convenient due to their reusability, but they may not be the best choice for high-pollution environments like Delhi. It is recommended to prioritise respirators or masks with a well-sealed fit and high filtration efficiency to maximise protection against pollution.
In summary, while cloth masks have their advantages in terms of comfort and reusability, they offer limited protection against pollution. For individuals seeking effective protection from pollution, it is advisable to consider masks with higher filtration efficiency, such as N95 or KN95 respirators, despite their disposable nature. Additionally, ensuring a good seal and fit is crucial to maximising the protection offered by any mask.
