Air quality worsens after Diwali as AQI reaches severe levels:5 smart air purifiers for cleaner indoor air that offer 450 sq ft bedroom coverage

Air quality in several parts of Madhya Pradesh has become a growing concern after Diwali, with pollution levels rising across cities. Bhopal and Ujjain have both recorded AQI levels above 400, placing them in the severe category, according to the monitoring figures provided. The Air Quality Index (AQI) is a measure used to indicate how polluted the air is and what its possible health effects could be. A higher AQI means poorer air quality and greater health risks, particularly for children, older people, and those with respiratory problems. While people cannot always control the quality of the air outside, they can take steps to improve indoor air quality. This is where air purifiers can help. These devices draw in surrounding air, pass it through filters to trap pollutants such as dust, smoke, and fine particles, and release filtered air back into the room. For people who spend several hours indoors, particularly in their bedrooms, an air purifier with a suitable room coverage area and a HEPA filter can be worth considering. Buyers do not necessarily have to spend a large amount to get features such as multi-layer filtration, sleep mode, and app connectivity. Here are five budget-friendly air purifiers available in India, along with their key features and prices. 1. Eureka Forbes Aeroguard 400G Smart Air Purifier Price: ₹9,999 The Eureka Forbes Aeroguard 400G is an option for people looking for a purifier for a medium-sized bedroom. It has a three-stage filtration system that includes a pre-filter, an activated carbon filter, and a True HEPA H13 filter. The pre-filter helps capture larger particles such as dust and hair, while the activated carbon layer helps reduce odours. The HEPA filter is designed to capture fine airborne particles, including PM2.5. Other features include Wi-Fi connectivity, a real-time PM2.5 display, sleep mode, and a filter replacement indicator. Its coverage is rated at up to 400 sq ft. 2.

Can an air purifier protect you from outdoor pollution? Air purifiers can help reduce indoor pollution, but they cannot eliminate exposure to polluted outdoor air. Their effectiveness also depends on room size, filter quality, maintenance, and how much polluted air enters the room. During periods of severe pollution, keep windows and doors closed when outdoor air quality is poor, and use an air purifier in the room where you spend the most time. Ensure that the room has adequate ventilation when outdoor conditions improve.
