Never heard about ULPA filter before. Is it fit for purpose? Dont want to buy something that is overkill and and overdesign but difficult to find spares and services.

its a technology above HEPA filter. you can google it. Its Legit. Air purifier, lebih halus lebih bagus.

Anybody knows if the compact Blueair Joy S is any good? For small room, the CADR spec seems acceptable. Not sure true or not.

Might as well buy 2 units of Xiaomi Mijia Air Purifier 2H for the price. CADR around 50% more than it.
HN selling RM799 for Joy S. 2H selling around RM399 or lesser

Joy S no meter, no app, no remote. use it to believe it work for you. replacement around RM200 for 1 years (assume 12hours daily) - review from Google
2H got app to monitor. filter cheaper but last for 150 days only.

Yup reason is to try other brand as i have opt for xiaomi for other room.

Since you already aware of the Joy S is inferior to 2H and you wish to try, ain't nobody gonna stop you lol 

Can look for used sets from FB/Carousell if want to try for the sake of try, but paying for a new one macam not worth for me.

Noted..already scraped Blueair joy S in plan..seems like only xiaomi is value for money and has high CADR.

One concern tho, I've read somewhere that Xiaomi air purifier will automatically turned its setting to lowest speed after few hours even after we set the speed manually to maximum, let's say before we go to sleep. There is no overriding this function, not to mention that xiaomi air purifier will stop functioning and force us to change filter after 150 days of usage.

Im researching on phillips now. Any good model u know that can be used for small bedroom? Dont mind the price...

Xiaomi Manual Speed got 1-2-3 only, but you can automate it using app re-set it to max speed if you wish for every hour.
IF: 08.00PM
THEN: Set to MANUAL
IF: 10.00AM
THEN: Set to MANUAL

I have no problem for this since I don't always open turbo 3 speed for more than half hour.

There are model doesn't come with RFID if that is a concern for you but forcing you to change filter is good for our health anyway. We human always have laziness or procrastination to delay our purchase filter.

guys, since got so many people recommending Xiaomi, i'm gonna get 1. may i know which model is recommended? There is 3H, PRO and now they even come out with 3C. and which one is True HEPA filter? it seems like 3H and 3C?
i'm confused 

if there is an airpurifier that can double up as a "fan" then i dont need to have two devices circulating air in my room

do you use fan or air con in your location that needs purification

I still got 80%/118 days left. So let you know again after end of 150 days. lol

Thanks for the update!

Btw, I just ordered a 2H!

"Lifespan" is stated as 150 days in the app and you will get a notification to replace it regardless whether the filter really needs to be replaced or not.

Do some read up on reddit where xiaomi purifier 3 onwards and that includes the pro version where there is a RFID chip in the purifier. Mixed reviews on whether you can reuse the filters past 150 days. Some reported the purifier does not turn on as scheduled or gives an error, fake filter or something causing it to be unusable. Some even use aluminium pieces to block the RFID sensor with mixed results.

If you dont mind changing every 150 days, filter replacements will cost RM 250/year (one h13 HEPA filter costs RM125)

Due to the above, for a peace of mind and no risk, I got the Xiaomi Purifier 2H instead which doesn't have a RFID sensor. Then I will use some cotton filters to wrap around thr filter and will try to vacuum the pre filter frequently, say every 2 weeks and hopefully the HEPA filter can last up to 1 year. If so, the cost of changing filters is only RM125/year.

Quick update: my 3H just turn into 0% and I can confirm still can run even without putting the new filter inside.
