Discussion Overview

The discussion revolves around the safety and efficacy of Sharp's Plasmacluster technology for air purification, particularly in the context of removing particulate matter and potential health effects associated with its use. Participants explore various aspects of the technology, including its mechanism, reported effects, and comparisons to other air purification methods.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant expresses concern about the safety of ozone emissions from air purifiers and questions whether Plasmacluster technology is ozone-based or not.
  • Another participant references evidence suggesting that certain air purification systems can efficiently remove particulate matter, although they cannot confirm its effectiveness for the specific application mentioned.
  • A participant raises a concern about the potential health effects of hydroxyl radicals produced by the technology, questioning whether these could harm the lungs or other organs.
  • Discussion includes references to human subject testing, indicating that while there were no strongly negative effects reported, some minor issues like headaches and eye irritation were noted, along with mixed results regarding positive effects.
  • One participant advises against linking to manufacturer materials, suggesting a preference for independent sources in the discussion.

Areas of Agreement / Disagreement

Participants express differing views on the safety and effectiveness of Plasmacluster technology, with no consensus reached regarding its overall safety or efficacy. Concerns about potential health effects and the reliability of evidence presented remain unresolved.

Contextual Notes

Some claims rely on studies from journals of varying quality, and the discussion highlights the need for careful consideration of the sources of information regarding health effects and technology efficacy.

TL;DR
Is this technology sound?
I'm looking for an air purifier because of dusts from the neighbor's 4 month long renovation and I only became aware of air purifiers lately.

I came across the Sharp Plasmacluster:

https://global.sharp/pci/en/

But I read that ozones are not safe. https://molekule.science/air-purifiers-ionic-ionizers-bad-or-good/

So the Plasmacluster is clearly not ozone based or is it one in disguised?

I tried to google for any negative comments about the technology and came across this:

What is your thought about the Plasmaclusters? Would you put one in your own room. And why?

Any comments appreciated. Thank you!

On the other hand, evidence showed that NAIs could high-efficiently remove PM including ultrafine PM (Figure 3), providing an alternative way to clean indoor air especially during haze episodes.

The systems are sold for other purposes but are good at PM (particulate matter) removal. How this plays out for your application I cannot say.

Let's go to this sharp plasmaclusters air purifier sold at amazon for example:

This is short youtube summary how it could deactivate viruses in air (?)

My concern is whether these OH radicals can directly affect your lungs or organs if you inhale them? Is the technology based on known or proven principle?
 
The link I gave you listed all of the human subject effects testing done - page 10. In general there were no strongly negative effects, some few minor reports of headaches, eye irritation, etc., which you expect to see.
Positive effects were a mixed bag - there were a lot of 'no effect' kinds of results.

Some of the links are to less than top notch journals as well.

Let's call it answered. Next time please do not link manufacturer's materials - videos, papers, etc., in your posts. We will just lock the post right away.
