Very informative guide, especially considering Delhi’s rising pollution levels. While air purifiers help improve indoor air quality, controlled environments like pharmaceutical and industrial facilities often require solutions such as an air shower for cleanroom to manage particle contamination at entry points. It’s interesting to see how different air-cleaning technologies serve both residential and industrial needs.
