The outdoor air is polluted no doubt, but factor in pollutants such as cooking gases, and the air inside your home can be worse—indoor air pollution has been linked to cancer, heart disease and dementia.
The Sharp FP-F40E (ideal for rooms measuring 30 sq. m in size) is a powerful air-filtration system. We tested this in a bigger 32.5 sq. m living room, registering an unhealthy 91μg/m3 of particulate matter (PM), according to our air quality monitor (Forbix Semicon; around Rs.7,000; Amazon.in).
In the automatic mode, the FP-F40E improved the room’s air quality by reducing the PM level to 10μg/m3 in 30 minutes. The same test, repeated in the manual mode at maximum power, reduced PM to 11μg/m3 in less than 15 minutes.
The FP-F40E’s thick filter helps catch finer particles. Its Plasmacluster feature uses positive and negative ions to pick off particles from static air, such as under the sofa.
Efficient and easy to use, the FP-F40E seems to be ideal for most homes.
