David Pui, China and India, efficacy

Just a quick note. Both the tower in Xian, China and the two 80 feets towers in India were designed by David Pui and his team. There are some sources available about that, and also the efficacy of the Xian tower, in the Further reading, External links or References sections. I may come back to add those content if I have time, but it would be great if others can add them too. --Dustfreeworld (talk) 15:08, 18 November 2024 (UTC)

Also, the efficacy of Daan Roosegaarde’s towers (the first) and the towers designed by David Pui (the largest) are different. The laters have much better efficiency. David’s tower uses technology similar to HEPA, while Daan’s only employed ionisation, and those mechanisms won’t differ too much from the air purifiers used at home. I read that from sources (I forgot which) when I started expanding this article long time ago. This information needs to be incorporated into the article in the future. --Dustfreeworld (talk) 15:47, 18 November 2024 (UTC)

• What I think should be changed: In the SALSCS section:

−

In 2016, a 100-metre (330 ft) solar-assisted large-scale cleaning system (SALSCS) tower was built in Xi'an, Shaanxi to tackle the city's pollution.

In 2016, a 100-metre (330 ft) solar-assisted large-scale cleaning system (SALSCS) tower was built in Xi'an, Shaanxi to tackle the city's air pollution.

• Why it should be changed:

It improves clarity by specifying the type of pollution.

• References supporting the possible change:
