style=\"font-weight: 400;\">From 2021 to 2026, there were only seven \u2018good AQI\u2019 (AQI under 500) days between October and February in Mumbai. During the same period, around 45% of winter days crossed India\u2019s 24-hour PM2.5 standard of 60 \u00b5g\/m\u00b3, and 99.3% crossed the WHO\u2019s guideline of 15 \u00b5g\/m\u00b3. This winter does not seem different because Mumbai\u2019s AQI was recorded at 174 on November 4, 2026 (according to aqi.in).\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, you should check the scale before running a comparison. aqi.in uses the US AQI. The CPCB\u2019s SAMEER app uses the National AQI, which has a lower reading. PM2.5 at 60 \u00b5g\/m\u00b3 scores 100, which is considered satisfactory in India, but about 154 (considered \u2018Unhealthy\u2019) on the US scale.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Does every home need an air purifier in Mumbai throughout the year? No, but the air quality varies.\u00a0\u00a0<\/span><\/p>\n<p><strong>Also Read: <a href=\"https:\/\/www.rentomojo.com\/blog\/air-purifier-for-home\/\">Do You Need An Air Purifier For Home?

The city usually gets winds of 12-13 km\/h, enough to disperse particulate matter. In 2022-2023, the speed dropped to about 4-5 km\/h. The sea and land breezes, which reverse every 3-4 days and get rid of pollutants, took around 10 days to do so that winter.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Due to slow air movement, local pollution becomes a persistent problem. It is found that much of the dust comes from the Metro and road construction. Cars add around 20% of emissions.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Does_an_Air_Purifier_Work\"><\/span><b>How Does an Air Purifier Work?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The air purifier has a fan pulling air through filters. It comes with washable filters that take out hair and grit. HEPA filters in air purifiers block fine particles. Some models also have an activated carbon layer for traffic fumes.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Does_a_HEPA_Filter_Work\"><\/span><b>Does a HEPA Filter Work?\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">HEPA filters can trap at least 99.7% of particles 0.3 microns in size, following the US Department of Energy Standard. PM2.5 is 2.5 microns or smaller, about 30 times thinner than a human hair. A basic air purifier with regular filters cannot block fine particles.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_are_the_Benefits_of_Air_Purifiers_for_Homes_in_Mumbai\"><\/span><b>What are the Benefits of Air Purifiers for Homes in Mumbai?\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Air purifiers can clean the room air. In Mumbai, an air purifier effectively works on lowering indoor PM2.5 and PM10 on high-AQI days. There are fewer allergic reactions from dust and pet dander. Air purifiers can also get rid of cooking smells with the carbon filter. Air purifiers can only work well in closed rooms. If you run an air purifier with the windows open, it will not deliver the results you want to see in your room.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Does_an_Air_Purifier_Work_for_Dust\"><\/span><b>Does an Air Purifier Work for Dust?\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">An air purifier works on dust in Mumbai, and a large part of the city is plagued by dust. Over the recent winters, PM10 (coarser dust) broke India&#8217;s 100 \u00b5g\/m\u00b3 daily standard on more than 82% of days. On the other hand, PM2.5 exceeded the limits on about 45% of days. In this context, washable pre-filters do much of the work. Make sure to clean the filters in winter. An air purifier for dust cannot work on what\u2019s already settled on floors and shelves.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Are_There_Benefits_of_Sleeping_with_an_Air_Purifier_in_Mumbai\"><\/span><b>Are There Benefits of Sleeping with an Air Purifier in Mumbai?\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">If your bedroom stays shut for the longest period, the air purifier can be effective. The benefits of sleeping with an air purifier are cleaner air for seven to eight hours at a stretch and fewer night-time allergy symptoms, such as a blocked nose. To get the full benefits of an air purifier in the bedroom, use sleep mode and check the noise rating in decibels.<\/span><\/p>\n<p><strong>Also Read: <a href=\"https:\/\/www.rentomojo.com\/blog\/does-an-air-purifier-work-in-delhi\/\">Does an Air Purifier Work in Delhi?
