You want good air purifiers, just get Honeywell

Just bought this - Philips AC-4014


Just a pure air filter with no ionizer or humidifier function. Has three stages of filtration - pre-filter (like those in aircon), carbon filter and finally a Hepa filter. Quite solid and thick those filters which is what I like. Filters can tahan 3 years before need to replace. Pre-filter can be cleaned by vacuuming or with water like those found in aircon

Here is what they look like -


Unfortunately, it doesnt come with a remote control like the Hitachi. Bought at the philips warehouse clearance for Rm729. Very worth it, I feel.

The airflow rate is 237 m³/h and is able to cover a room size of 55m2. That means pretty much a living room

Hitachi also very good but they come with humidifier which adds to the cost. The A6000 series has a heavy duty Hepa filter.

Hitachi air purifier very solid but comes with the added cost of the humidifier. If you don't need humidifier, can try Philips. Just purely an air filter.

According to wiki - http://en.wikipedia.org/wiki/HEPA
To qualify as HEPA by US government standards, an air filter must remove (from the air that passes through) 99.97% of 0.3 µm particles

Philips Specs - http://www.philips.com.my/c/air-purifier/a...=specifications

replacement for one set around Rm160-180. you can call philips to find out

anyone use BlueAir before?
Model 203 - Rm1559,

Saw at Robinsons Garden

When you buy new filter unit, Just let the filter unit sit in the box. Then make a tiny hole for the power plug to come out. This way your Hepa will last forever and ever

That doesnt makes sense at all
Using a humidifier will make your room more humid and the aircon will have to work harder to get rid of the moisture

first of all, if the humidity is low, you feel more comfortable and cooling
you turn on humidifier - that already defeats the purpose of the aircon

humidifier may help mositurize back your skin BUT it wont help in reducing your electricity as you claimed

please google - "how humidity affect your air conditioning"

"When humidity levels spike, however, most systems can’t cope. Humidity affects air conditioning negatively because it cancels out the cooling effect. When the humidity is too high, your home will feel warmer than it actually is. You’ll have to keep your air conditioning system running but won’t derive nearly as many benefits from using it. In other words, you’ll pay more to cool your home but won’t actually cool it that effectively."

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
