I just bought Xiaomi Air Purifier 2S. Compare with the model 2, only difference are that it now uses a laser sensor. I think version 2 was using infra red? The other difference is that it now has a OLED display screen - got PM2.5 readouts, Temp and Humidity

You can connect this air purifier to Mi Home app and if you got the Mi Gateway, you can set some automation rules like if air quality goes above this amount turn on the filter etc. Yes it works even when it is not turned on. You can also set it to notify you on your smartphone

My previous air purifiers, I turn them on and set the timer, that’s it, without knowing if I need air purification or not

Price -
Version 2.0 around 479-499
Version 2S around 679-788

There are 3 types of replacement filters - Economy, Anti-Bac and Enhanced. All has 3 stages of filtration which includes charcoal and HEPA. They cost around 130 to 150. They should last about 6 months but really depends on your usage. The app has a reminder feature that will tell you when to replace

There is only one filter to replace - it has three layers
There are three types of filters to choose from - economy (blue), antibacterial (purple) and enhanced (green). You only need one of these.
Please see the pics below - Sorry for the confusion

I think based on 24 hours usage. At my rate of using, I think mine can last me more than a year cause I set it to turn on if it detects more than 35 Air quality. It has a counter that shows the number of days left and mine haven’t move since I used it. Btw when it tells you it’s time to replace, it doesn’t mean the filter will stop working. Vacuuming it might extend its life. But I think vacuuming it only removes dust from the first layer and not from the Hepa and carbon layer. And since it’s cylindrical, it will be difficult to handle. You will only get dust back into your environment so I dont recommend vacuuming.

If I’m not mistaken, Sharp has a buildin ionizer. That’s the only thing different. I personally don’t like my air purifiers to have ionizer feature but others might find it useful. Oh and now they have an added feature to catch mosquitoes

mind share with where u get such discount? ty

It comes with 2 filters with HEPA/antibacterial & activated carbon/cold catalyst layer purposes. Sterlize & Anion features on HAP40 need turn manually, while HAP30 all auto (HAP40 & HAP30 just need switch on, the fan speed from 3 down to 2 then 1 automatically according to air quality)

much cheaper than xiaomi + local 3 years warranty, 2 filters in 1 set replacement also much cheaper, although I don't really like the khind gold color 

The humidifier has fan speed 1, 2, 3 as well. While HAP40 working, if u try move the unit it will power off automatically, probably safety feature with the water tank.

Both timer feature I din't use, should be quite standard
Gimmick or air really purified? My wife said her sensitive nose felt big different before & after, it does help up a lots.
Thanks to your link, I bought hap 40 & hap 30 total Rm620 

Could you give some review on the dust reduction? Is it really efficient ? Did you manage to get any filter replacement sellers ? I searched through some websites online but couldnt manage to get any sellers for the filter replacement.

Dust need to wait until saturday to know, usually 1 week tv rack dust will appear

Yest she walked near the hap40 after applied some heavy smelly skin oil treatment, the machine air quality turn to orange color immediately
