Diwali 2025 has triggered pollution issues which means people are looking to buy air purifiers and here’s a detailed guide about it.<\/h2>\n
\n

Diwali 2025 in Delhi means the demand and research for air purifiers are back in the headlines. Buying an air purifier is tricky but it has become unavoidable. But with no industry standards in place in India, consumers are at the mercy of the brands. <\/span>The prices of air purifiers can range from anywhere between Rs 8,000 and Rs 1 lakh.<\/span><\/p>\n<\/div>\n

\n
\n
\"Size<\/figure>\n

The size of the room (preferably in square metres) in which you wish to install an air purifier. The portable air purifiers are meant to cater to only one room but bigger space in the house might bump up the budget.<\/p>\n

<\/div>\n

\n
\"Type<\/figure>\n

The most commonly available filter type is HEPA (High Efficiency Particulate Air). It can filter most (up to 99.9%) air borne particles of small sizes of up to 0.3 microns. For general usage, HEPA filters get the job done.<\/p>\n

<\/div>\n

\n
\"Check<\/figure>\n

There are some particular terms that help you determine the quality of the purifier. The performance of a particular air purifier model is rated by its coverage area, Clean Air Delivery Rate (CADR) and Air Changes Per Hour (ACH). ACH or Air Changes Per Hour is basically how often an air purifier can clean the air of its claimed coverage area in an hour. This is important because pollutants constantly enter your room and the air purifier needs to constantly clean the air.<\/p>\n

<\/div>\n

\n
\"Filters<\/figure>\n

The cost of replacing the air filter and its availability should be also kept in mind. Opt for a model with a pre-filter as it increases the life span of the filter inside. Filters usually cost in the range of between Rs 1,500 and Rs 2,500 with a lifespan of around six months. Also, do not forget to enquire about the availability of filters.<\/p>\n

<\/div>\n

\n
\"Noise<\/figure>\n

Noise levels should be around 35 decibels when the fan is running at the top speed. Do not opt for models with above 55 decibels rating. It tends to be disturbing during sleep.<\/p>\n
