The Goods and Services Tax (GST) Council may consider reducing the tax rate on air and water purifiers from 18% to 5%. This potential move comes amid worsening air quality and calls to classify these devices as essential public health equipment. A lower GST could make purification technology more affordable, though the timing of the next Council meeting and consensus among states remain unclear. The Delhi High Court had previously urged the government to convene a meeting to consider reducing GST on air purifiers.
