Wear N95/N99 masks with carbon filters, exhaust valves, and regular filter changes
When visiting Delhi, it is imperative to take precautions to safeguard yourself from the hazardous air pollution. One of the most effective measures is to wear N95 or N99 masks with carbon filters, exhaust valves, and regular filter changes. Here's why this combination is crucial for your respiratory health:
N95 and N99 Masks:
N95 and N99 masks are designed to filter out fine particulate matter, which includes harmful pollutants such as PM2.5 and PM10. These particles are released into the air by vehicular emissions, stubble burning, and construction activities, contributing significantly to Delhi's air pollution. By wearing an N95 or N99 mask, you can filter out up to 99% of these fine particles, providing a significant level of protection to your respiratory system.
Carbon Filters:
Carbon filters play a crucial role in enhancing the filtration capabilities of masks. They are designed to adsorb a wide range of pollutants, including volatile organic compounds (VOCs), odours, and hazardous gases such as nitrogen oxides, which are commonly found in vehicular emissions. Carbon filters help reduce your exposure to these harmful gases, providing an additional layer of protection beyond what a basic mask offers.
Exhaust Valves:
Exhaust valves in masks serve a vital function by allowing exhaled air and moisture to escape more easily. This feature helps reduce the buildup of heat and moisture inside the mask, making it more comfortable to breathe, especially during extended periods of wear. Exhaust valves can also help prevent the accumulation of carbon dioxide, ensuring that you inhale fresher air with each breath.
Regular Filter Changes:
It is essential to change your mask filters regularly, especially if you spend a significant amount of time outdoors in polluted environments. Clogged filters can increase breathing resistance and reduce the effectiveness of the mask. Regular filter changes ensure that your mask continues to provide the intended level of protection against particulate matter and gases. Aim to change your filters as per the manufacturer's recommendations or when you notice any signs of clogging or decreased breathability.
By wearing N95 or N99 masks with carbon filters and exhaust valves, and by regularly changing your filters, you can significantly reduce your exposure to harmful pollutants in Delhi's polluted air. Remember to combine this practice with other precautionary measures, such as checking real-time air quality indices and minimizing outdoor activities during "Severe" or "Very Unhealthy" conditions.

Avoid outdoor activities and exercise during high pollution periods
When the air quality index (AQI) indicates high pollution levels, it is best to avoid outdoor activities and exercise. Instead, opt for indoor activities or less strenuous exercises such as yoga or stretching. If you must exercise outdoors, take certain precautions to minimise your exposure to harmful pollutants.
Firstly, check the AQI in your area using apps like AQI India or websites from the CPCB. These provide real-time updates on air quality, including pollutant levels, air quality indices, and health recommendations. Avoid exercising outdoors during "severe" or "very unhealthy" conditions. Try to exercise during early morning or late evening hours when pollution levels are typically lower. Avoid rush hours and peak pollution hours, usually in the mornings, when vehicular emissions are at their peak.
Choose your exercise spots wisely. Parks and green spaces tend to have better air quality due to the presence of trees, which act as natural air filters. Select locations away from major traffic intersections and industrial areas, as these areas have higher levels of harmful vehicular and industrial emissions.
If you must exercise outdoors during high pollution periods, invest in a high-quality pollution mask designed to filter out fine particulate matter (PM2.5) and other pollutants. Opt for N95 or N99 masks, which can filter out up to 99% of fine particulate matter. If you're outdoors often, consider a reusable mask with changeable filters, ensuring you change the filters regularly as clogged filters can make breathing harder.
Finally, adapt your workout routine. If the air quality is poor, consider shorter, more intense workouts instead of prolonged sessions. This will help minimise your exposure to pollutants while still allowing you to exercise. Remember, your health should always come first, so adjust your routine as needed to protect yourself in high-pollution environments.

Use indoor air purifiers and air-filtering plants like aloe vera and ivy
Delhi's air pollution is a severe issue, with over 11 million registered vehicles contributing around 40% of the city's air pollution. The situation is worsening, with annual growth in the number of vehicles, and the burning of agricultural stubble in neighbouring states adding to the problem. The pollution has very real health consequences, with short and long-term exposure causing issues such as asthma, heart disease, allergies, and more.
To protect yourself from Delhi's poor air quality, it is essential to take control of the air you are breathing. One way to do this is by using indoor air purifiers. While these cannot eliminate all pollutants, they can help to reduce them. Portable air purifiers are designed for single rooms, and you may need more than one, depending on the size of the space. HEPA air purifiers, for example, can help to reduce gaseous pollutants, and those with activated carbon filters are effective at trapping pollutants such as volatile organic compounds (VOCs) from vehicle exhausts. Other filters, such as zeolite, are also good for absorbing VOCs and removing odours.
Another natural way to purify the air is by introducing air-filtering plants. These act as nature's filtration system, improving air quality by absorbing carbon dioxide and other airborne pollutants. NASA scientist Bill Wolverton's 1989 study highlighted the benefits of plants in indoor spaces, particularly in areas with poor air quality. When choosing plants, consider the size of the room and the light conditions. Bigger rooms can accommodate larger plants with greater air-purifying abilities, such as the Areca Palm. Smaller spaces may benefit from a single plant like the Lemon Button Fern, which adds elegance to compact spaces. Low-maintenance options include the Black Leaf Dragon Tree, and pet owners should opt for pet-friendly varieties.
Aloe vera and ivy are two examples of air-purifying plants that can help improve indoor air quality. Ivy, in particular, is an excellent natural air purifier, absorbing formaldehyde, xylene, toluene, and carbon monoxide. Aloe vera, meanwhile, is a low-maintenance succulent that emits oxygen and absorbs carbon dioxide, helping to keep the air clean. These plants can be placed indoors to help combat the effects of Delhi's pollution, especially when combined with the use of effective air purifiers.
