Hi everyone, just sharing my experience. I hv skin allergies and my doctor recommended me to buy an air purifier (coz I don't seem to be allergic to any food), which sent me on a journey to search online.
Apparently Alen is the best but I haven't seen it here. Blue air has great reviews too.
Now just to prepare everyone, blue air doesn't have fancy features that the Japanese company has and claims like auto detector etc.
Google search online leads you to mostly western favoured brands. Sharp and Panasonic have nice sites (but sharp is too confusing and don't clearly state the differences of the models ). All seems fancy but apparent negative ion isn't a good thing anymore and some emits ozone which is bad.

I searched the Internet for around two weeks, reading reviews etc. some ppl have special devices to measure air quality and blue air was good. Also lots of comments on their hepa silent which was silent enough to sleep peacefully. Also, filters should be HEPA standard to remove 99.9% of whatever particles which some brands won't dare say they hv hepa standards coz they don't. I even went to the ESH shop in ss2 to take a look and the sales assistant was helpful and mentioned good things about the model.

At the end, I settled for blue air. I bought the basic model (203) at RM 1599 at homedec on 1st may which came with an extra free basic filter (there are two types - basic and charcoal for odour removal).  While this seems pricey, Coway and home master are not cheap too. Coway has a rental policy but for a minimum contract of 24 months (which means the price is almost the price of the unit itself! But they claim they do servicing etc).

I love my blue air! The highest lvl mode is noisy but the middle mode is ok and the lowest setting (hepa silent) is silent.

Noise: hepa silent is really silent!
Weight : I can carry it to other rooms ^^ wahahha save money. Note that their higher end models have wheels. Don't expect to clean the house house air with a smaller model la....read their specs. Also it's made of metal so more sturdy but means more heavy.
Price: seems expensive but reasonable if u compare to other brands
Warranty : 3 years
Customer service : VERY important point....why I am posting is coz of this. Sales man ok, sales ppl ok, phone customer service ok BUT phone to follow up on delivery was a rude person and my delivery was incomplete. Then being typical Malaysian, I went to their company website and complain. Within 30 minutes, their company director called me up to try and understand and resolve my issue. To me, issues and hiccups can happen, but how you resolve it is most important. Her genuine gesture and professionalism was very impressive. A+++++

Anyway, if you want blue air, you can buy from their office or they can deliver to you or you can visit ESH electrical shop too. The blue air distributor website is www.visionary.com.my

Btw, I really don't work for them ya. You can pm me to ask about my blue air. Hehe. It's really basic. So easy to change the filters too.
Last but not least, I think air purifiers are NOT vacuum cleaners. Don't expect it to vacuum all your dust. Hahaha.

Does air purifier REALLY can eliminate dust?

I have dust problem in my house. It's everywhere.. Daily mop really tiring..

Bro. You should vacuum and mop your house daily to keep it clean.
Air purifier cannot eliminate dust.
Certain brand will bring down the dust and you will see the area nearby your machine to be full with dust.
Eventually you will need to vacuum and mop again.

Technology advancement = people getting lazy and try to avoid using own energy to solve problem.

The problem is I don't know from where the source came from..

I have remove all carpets in my house, put hippo in my wardrobe, wash my curtains and sofa cover weekly but still dust is everywhere..
Vacuum and mop daily very tiring bro.. That's why want to get air purifier AT LEAST can help to eliminate those dusts. 

Cheras area but not near to highways..

Except the road in front of my house being used as main road by the neighbors to go morning pasar.. 

Can it be due to that?

Window rubber seals / sliding doors - done renovation last time so should be ok..

Gap between doors and floor - This area I need to tackle..

But later no air coming in then I die suffocate pulak.. 

Never thought sliding doors can be the problem..

A bit hard for me to wet the outside before opening the sliding doors because those contractors did not do the tiling correctly. So water stagnant at the floor.. 

However I can clean those sliding areas first to reduce the dust..

Wet the road? Well that's new..

Indeed.. Can see a lot of dust trapped at the sliding rail.. Clean it and after couple of days can see dust trapped again.. 

But since i seldom open the sliding door thus never bother to clean that area..

So now I need to clean those areas frequently..

Spent so much ady summore kena con by contractor.. Paisehh

Whoa.. like that sure more dust enter your house leh..

Then do what? Stay at kampung? 

Anyway, my friend went to aeon just now and bought air purifier brand 'cleen aire', the one that we put water inside the thing. The salesman told him that this ap can eliminate dust..

Is it true?

Told my friend about this.. Now he don't have heart anymore at the 'Cleen Aire' 

I have dog staying inside the house so my AP will on for 24/7.
Yes, you are right that the air and dust can only reach certain length. For Blueair is exactly 700sqft and Coway only up to 400+sqft.
That is why i am getting the Blueair.
Blueair is renowned worldwide and it is an Europe brand. I usually trust Europe products more. 

Well, can we use humidifier along with a/c?

Or humidifier and purifier actually the same thing?

Exercise under cold environment is bad? How about fitness centre then? 

Thanks for your advise.. 

Wasting money to buy sickness - Nice quote bro..

But by walking daily outdoors we're facing with car/motor smokes, residents burning rubbish, etc.. Not including criminals out there..

Anyway, everybody got their own point of view, right? 

Ok now.. U bring wire cutter > cut ah long papers > side income

Mind to share with me..?

Thank for your tips..

My house area a lot of those ah long papers.. Time to work..!!!

Anyway, my friend is selling sharp KE-40 ap at RM750.. Does it worth getting it?

Hahaha.. You kill me straight to the heart.. 

Thanks for the tips! Haha.
