What happened to Mumbai's Air Quality towards the end of December 2024?

Mumbai has recently experienced a significant decline in air quality, with the Air Quality Index (AQI) reaching concerning levels. On December 26, 2024, the AQI escalated to dangerous levels across multiple locations in the city.

“I often wondered if this will ever go away,” said Deshpande, who ended up visiting the doctor five times in that one month. “Pollution has increased so much in recent years that I fear it will only get worse. Despite the impact, many educated residents in our gated community refuse to sacrifice crackers during Diwali. How will we live like this?” via NewsLaundry


This deterioration has persisted, with reports indicating that Mumbai's AQI remained in the 'poor' category for seven consecutive days.


Several factors contribute to this decline in air quality:

  • Construction Activities: Ongoing construction projects generate dust and particulate matter, exacerbating pollution levels.

  • Vehicular Emissions: The increasing number of vehicles on Mumbai's roads leads to higher emissions of pollutants such as nitrogen dioxide (NO₂) and particulate matter (PM₁₀).

  • Industrial Emissions: Industrial activities release various pollutants into the atmosphere, further degrading air quality.

  • Weather Conditions: During the winter months, cooler temperatures and reduced wind speeds can cause pollutants to accumulate near the ground, leading to higher AQI levels.

The health implications of poor air quality are significant. Research indicates that increased levels of PM₁₀ and NO₂ are associated with respiratory issues such as cough, breathlessness, wheezing, allergic rhinitis, and chronic obstructive pulmonary disease (COPD).

In light of these conditions, using an air purifier can be beneficial, especially indoors. The uBreathe Air Purifier is designed to filter out harmful pollutants, providing cleaner air and reducing health risks associated with poor air quality.


While individual measures like using air purifiers are helpful, addressing the root causes of air pollution requires collective action, including stricter emission standards, sustainable urban planning, and increased public awareness.

Indoor Air Quality Improvements

  1. Use Air-Purifying Plants

    • Why: Plants like Snake Plant, Peace Lily, and Areca Palm filter toxins like benzene and formaldehyde. NASA’s Clean Air Study confirms their air-purifying properties.

    • Action: Place 1 medium plant per 100 sq ft indoors.

  2. Invest in Air Purifiers

    • Why: uBreathe Air Purifiers 5-stage filtration will remove up to 99.97% of PM₂.₅, TVOCs, gaseous pollutants such as SOx, NOx & SOx and allergens! Studies confirm reduced respiratory symptoms with regular purifier use.

    • Action: Opt for a purifier like uBreathe with advanced filtering technology.



  1. Ventilate Smartly

    • Why: Ventilation prevents indoor pollutants from accumulating. Use exhaust fans and cross-ventilation when AQI outdoors is better.

    • Action: Check AQI apps before opening windows.

  2. Control Humidity Levels

    • Why: Mold and dust mites thrive in high humidity, contributing to indoor air pollution. Keeping humidity under 60% helps.

    • Action: Use dehumidifiers and fix leaks promptly.

  3. Avoid Synthetic Cleaners and Fragrances

    • Why: Many release volatile organic compounds (VOCs) that irritate lungs. Studies show VOCs worsen indoor air quality.

    • Action: Switch to natural cleaners like vinegar or baking soda.


💡 Quick Wins

  • Opt for energy-efficient appliances to reduce emissions.

  • Avoid idling vehicles near residential areas.

  • Push for community-level air quality monitors to track progress.

Every small step adds up to cleaner, healthier air!
