Air purifiers from Rs 5,000 to Rs 20,000: understand the key points before buying
CNN Central News & Networks / ITDC India ePress / ITDC News / Agencies, Bhopal:
Amid rising air pollution in several cities across the country, maintaining clean air inside homes has also become a challenge. In this situation, demand for air purifiers is increasing. Several options are available in the market in the price range of Rs 5,000 to Rs 20,000, but buying a device only by looking at the price and brand is not the right decision. To choose a better air purifier, it is important to understand its filtration capacity, room size suitability, CADR and the cost of replacing filters.
Check the quality of the HEPA filter
While buying an air purifier, first pay attention to its filter. A HEPA filter helps capture dust, pollen, smoke and fine particles such as PM2.5 present in the air. However, every company’s HEPA-type or HEPA-like claim is not equal to a genuine HEPA filter. Therefore, check the technical details and certification of the filter before buying.
Understand cleaning capacity through CADR
CADR, or Clean Air Delivery Rate, indicates how much clean air a purifier can deliver in one hour. The higher the rating, the faster the device can clean the air under similar conditions. For a large room, it is better to choose a model with higher CADR. Do not rely only on the maximum coverage area stated by the company.
Choose the device according to room size
A purifier designed for a small bedroom may not be effective in a large hall. Before buying, measure the length and width of the room. Also consider the room’s height and open space. Information on air changes per hour (ACH) is also useful, as it shows how many times the room’s air is filtered in one hour.
Importance of activated carbon and sensors
If there is a problem of cooking odour, smoke or other gaseous pollutants in the house, choose a model with an activated carbon filter. It helps reduce some odours and gases. PM2.5 sensors and auto mode are also useful features, but they are not a substitute for the actual capacity of the filter.
Check filter and electricity costs too
Before buying an air purifier, make sure you know the price, availability and replacement interval of its replacement filters. Also check electricity consumption and machine noise at different speeds. Do not buy an expensive model only by looking at smart features or an attractive display.
According to experts, an air purifier can help reduce exposure to indoor pollution, but it does not provide complete protection from pollution. For better results, it is necessary to choose a model with the right capacity, run it regularly, maintain the filters and reduce sources of smoke and dust inside the home.
