First, what you provided is not a transcript. It's marketing copy scraped from a Swiss retail website. There are no timestamps because it's not a video. I don't care about the format, so I will summarize the information by product, which is the only logical way to do it.
Abstract:
This text provides product descriptions for five models in the Xiaomi Smart Air Purifier 4 series: Compact, Lite, 4, Pro, and Elite. The models are differentiated primarily by their Clean Air Delivery Rate (CADR), recommended room size, noise level, and specific features. All models claim to filter 99.97% of particles down to 0.3 microns and offer smart control via the Mi Home App and voice assistants. Higher-end models add features like negative ion generators (4, Pro), advanced sensors (Pro), and UV-LED/plasma sterilization (Elite). As far as I can tell, the information is entirely based on manufacturer marketing claims.
