Shame on Us! Asleep at the Wheel, page-26

Air is a big thing world wide, working population will always be exposed to bad air a few hours day travelling to and from work.
The demand will come from business environments and house holds where at least if you can get some 20 hours of quality air the savings in health issues will be in trillions, that's my basic view on all this.

The item below is from one of Chain's top air purifier OEM/ODM manufacturer which is something that all the OEM players would view things.
The last section I put in bold, just imagine if PO3 had a score of four.


"As the manufacturer of air purifier products, the strength of OEM/ODM manufacturers directly affects the future development of the products. If the quality of OEM/ODM products frequently occurs, brands and OEM/ODM manufacturers will not be able to gain a foothold in the net and air market. Therefore, it is very important to choose a strong OEM/ODM manufacturer.

The evaluation of the four basic technical indicators of air purifiers: CADR (clean air volume), CCM (cumulative purification volume), energy efficiency grade and noise standard.

These four indicators have evaluated the performance of air purifiers in terms of purification capacity and service life. A high-quality air purifier should have high CADR value + high CCM value + high purification energy efficiency + low noise, only one strong is not strong, “three high and one low” will be considered strong!

For example, Olansi Air Purifier K15 leads the new national standard with its advantages of three highs and one low."
