look for very good air purifier.
by reading this:
http://www.allergy.com.sg/airCareFAQ.html
found that TRUE HEPA is the one i looking for.
In the market, alot model selling Plasma Cluster type.
Some how this website said will harmful to human too
i guess "TURE HEPA " is a good filiter. I hope so. AS hospital (ICU ) also using it.
but the website sound like promote honeywell model only.
by compare honeywell VS osim Air purifier,
lets take a quick SPec of OSIM,
OSIM come with :
- True HEPA
- UV filter ( i like most)
- Negative-ion Purification
- other fine filter
-High Absorbent Deodouriser ( i think is carbon too )
Honeywell -
- True HEPA
- Carbon
hmmmm, i think honeywell got better True HEPA because of larger circumference. But don't have other filter eg: UV, neg ion etc etc.
I also found a product call IQair
Their product so call more fine HEPA. Instead of 0.3 micron, there are using 0.003 micron. Some model for hospital and some model as good as cleanroom enviroment. But is it real??? But there didn't come with UV or other technology to kill virus. Does HEPA itself help??
So should i buy Iqair with good HEPA only or OSim, whereby osim have normal grade HEPA but have alot kill bateria techno like UV and Negative-ion Purification.
my purpose is to have clean air and free from virus and baterica. which one to buy?
