Oh I thought you wanted 2 units to cover 1 bedroom. In that case, one purifier for each room.

Hepa filters work la, regardless of purifier brand, evident when you observe how dirty the filter is after x months.

Other features such as ionisation - Plasmacluster from Sharp, Nanoe from Panasonic or Virus Doctor from Samsung, is optional. I did not read too much into this actually.

Hardly any source that directly compares a certain model from Sharp vs Panasonic vs Samsung vs Xiaomi with detailed stats like a proper noise test, airflow/noise ratio, filter lifespan/price comparisons. Quite a bummer as the tech industry is the total opposite: pc hardware, mobile phones, etc.

Air purifier not a widely searched subject, hence, you don't see much reviews on certain models on the internet or youtube. Manufacturers not providing enough details, for example the noise levels at each fan speed or the minimum/maximum noise level was a little frustrating (Looking at you Samsung and Xiaomi).

This review is not bad though! https://pokde.net/blog/mi-air-purifier-pro-...e-air-purifier/

DO NOT ever recommend an ionizer based air purifier to a person with asthma. Plasmacluster is just an another patented marketing name of ion technology (layman term ionizer) by Sharp.

Medical Center/Hospital wouldn't use ionizer, they use HEPA based technology but not Ion based tecnology for their air filtration system.

Asthma people need to avoid all Ion based tech air-con and/or air purifier.

What is your budget? Around RM1k - RM2k per air purifier

Noted I will not buy the ionizer/plasmacluster type. Anything esle that an asmathic sufferer needs to avoid?

Go look for Atmosphere Sky.
Highly recommended by doctors, pediatrician and widely use in hospital now.

Get review from users who are using it.

Hi may u point out where is the uaer review?

The Xiaomi purifier seem impressive. Will definitely check it out for living hall usage.

Do u know about the after sales service? Is the filter change out easy and widely available in Malaysia?

after sales is good if seller honor the warranty. for xiaomi products I always buy from dasher (either lazada/shopee) coz they honor the warranty. filter & other parts is widely available, coz many people using xiaomi air purifier since years ago.

Why not check for ULPA purifier instead of HEPA, more refined at least 10 times.

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.

some DiY filter also okeh... suction fan on top of HEPA filter or other

That is your basic guideline where to start searching for.
1. 133CFM / 230m3h
2. 100CFM / 170m3h
3. 233CFM / 400m3h

Try get a Xiaomi Air Purifier 2C/2H/3H. These are using the basic standard affordable HEPA filter with micron size 0.3
Some high-end HEPA filter can go as small as 0.0024 like the one from Amway. Dyson also got as got their HEPA as small as 0.1 microns filter but with 70 CADR.
Coway/Cuckoo also got, but beware avoid ionizer feature, their product outright is not worthy due to spareparts are limited to purchase, while rent monthly option are easy to own but pricey in the long run. (Personally always recommend outright purchase if you can afford)

Ok noted. Ive been eyeing Xiaomi Air Purifier Pro for living room. For the bedroom, im still thinking whether to try other brand just for comparison.

I heard that Xiaomi product will turn off our manual setting if we set it manually to high mode and go to auto minimum setting after few hours. Is it true? How to rectify this cuz I'll need constant good quality air especially at night.

Since you have estimated RM2,000 for each purifier. Which mean you have RM6,000 budget to buy 3 air purifier.

1. Buy a "USED" Amway Atmosphere Air Purifier (Gen 2 - not the latest one) from Carousell/Facebook - around RM1,500+
- Flagship/Top high end grade air purifier (new one cost at RM4500++)
- Prefiter included (washable like air-con)
- HEPA filter micron 0.009 (everything you need is this filter - replacement cost around RM500, lifespan last around 1-3 years)
- Carbon filter to filter odour (you can skip to replace this filter if want to save budget - cost around RM400)
- CADR 400 m3/h to suit all your room size
- Allergy UK certified, AHAM certified (US standard), Energy Star certified (save electricity)
- Spareparts still sell by Amway in case need repair (Amway have track records sell their parts for more than 10 years after stop selling the model)
PS. I was still using this model for more than 6 years, it solved my nose allergy problem. And I even give my father use during his time resting at home after surgery from cancer. I personally high recommend this due to reputable company and parts availability even it is used model / no longer selling this gen 2 model. You can go to Amway HQ PJ to check this old model see still got display or not.

2. You should be left around RM4,000 budget
Buy a NEW Xiaomi Air Purifier Pro/3H (You can get 2-3 units with these balance of budget)
- all Xiaomi Air Purifier shared the same 0.3 micron size of HEPA filter (min standard for HEPA are 0.3 micron and below)
- Xiaomi should fit all your requirement as well. CADR 300 m3/h to suit all your room size
- The only cons that most people complain is their new generation come with RIFD to detect filter expire to force u replace otherwise not spinning at all (I just use for more than 1 month so no idea)
- and the filter lifespan is shorter than most of the competitor. is cheap to replace but shorter life span compare to those 1 years.
PS. I just bought 3H model, not much to comments, plan to put in baby room few months later. Currently using by me as well. You can walk in any Mi Store or Senheng to check display model.

3. There are some similar price range air purifier from Philip model AC2887. Their HEPA filter are much longer than Xiaomi. around up to 24months claim by them. The machine around RM1400+
PS. I also survey this before but end up I prefer the fancy feature from Xiaomi and cheaper ownership price.

There are still few out there like BlueAir 490i/690i but new one cost like RM3400/4000++ too ( with Hepa and high CADR)
Sharp majority come with Plasmacluster, as I said earlier, asthma must avoid all ionizer
Both Coway/Cuckoo most of the model come with ionizer, low end CADR are low.

Things to consider:
1. Performance (CADR, Technology (HEPA are most important))
2. Initial Price to ownership (outright/rent)
3. Cost of filter replacement (life span and price)
4. Warranty? How long and if not, replacement part / spare part still available?
5. Others certification (AHAM / Allergy UK etc)
6. Other fancy feature (smarthome/nightlight etc)

There are EPA, HEPA and ULPA. Can google for these info.
ULPA Filter vs. HEPA Filter: What's the Difference & Why Does It Matter?
https://www.hepacart.com/blog/ulpa-filter-v...-does-it-matter

Just like comparing Activated Carbon Filter VS Membrane Filter (or RO filter) for example.

Thanks for the very informative reply. Will greatly consider the advice.

As per Xiaomi filter, how long is the lifespan on average? And how easy to buy and install the filter? Seems like xiaomi features are impressive, but im going to try philips for the rooms maybe. Will heed ur advise to avoid ionizer.

"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.
