I bought this from taobao to replace my dylos as the result is comparable and it can also measure HCHO, CO2 andVOC as well.

Interesting company and I have read about his experience using the snapon HEPA before but I didn't realize he actually starts a company for it.

禾用過飛記,DYSON及小米3s.

小米3S係最平,吸塵粉過濾能力最高及最靜。

濾芯約$210.長開用半年。

其實成本就主要係HEPA filter.
同一個名, 唔同級數差好遠. 亦反映係價錢上.

至於監測儀, VOC 會毒化, 要定期換sensor, 所以唔會買. CO2 sensor, 如果係用瑞典果粒, 零件價都兩舊以上...
叫價一千內既, 應該唔係果粒.

I agree with what you said ... but many won't use HEPA more than 12 or 13 ... cos there''re test that 12 is a balance for getting the air through. Of course one could design an extreme air flow with super Hepa standard, but that could be huge ... but once we open the windows ... anyway it's a compromise in reality.

I certainly won't expect to use the 1k sensor for life ... it's reality ... luckily i am not living in industrial area.

#24 I almost bought this.

Did you import from Amazon or the site directly?

The design rules everything for this model when 'look' is a primary factor.

It is certainly an interesting read from Taobao about Smart Air

I cannot read the details of SGS safety certificate. I cannot find any safety logo from the webpage.

It claims it's bigger products have been banned unfairly by Taobao because of safety concerns reported by CCTV. So they would go obtain a safety certificate and put it onto the unit.

Could you explain a bit more? I couldn't find your news and don't understand what happened.

But the Sqair model is still available.

I found their safety standard here:

https://smartairfilters.com/learn/smart-air-knowledge-base/does-the-sqair-have-a-safety-certification/

Sqair has domestic CQC safety certification and European standard CE certification. In addition to safety certification, Sqair has passed the performance-based national standard GB / T18801-2015.

You can view the certificates online using the links below:

Sqair CE Certificate: http://smartairfilters.com/wordpress/wp-content/uploads/2020/02/CE-GZES1907020436HS-REDACTED.jpg
Sqair Performance Certificate: http://smartairfilters.com/wordpress/wp-content/uploads/2020/02/Sqair-HEPA-Performance-Certificate-KJ20191225-EN.pdf

I see, you want SGS safety certificate ...

I can share the data later tonight. I have an IQAir and a Sharp unit (the one claims to have 10 years HEPA life span).

I don't keep my windows fully closed to balance the CO2 concern and pm2.5 level....

Thanks & Good luck !

I have no objection to Made in China products. My phones & my computers are made in China. I do have concerns on China brands.
