My office that model more boring. But is safe me a lot from toxic smoke and smell. And when haze period.

I m not sure the sharp rm400. My office 1 cost RM1600. It can detect the bad smell and air pollution.

Will change to red and the fan start to go high when detect. Even my nose can't smell anything. It is scary when I alone work at night. Macam ada ghost when it suddenly change mode.

Why RM60/mth ? Is it for rent?

Not sure what is the quality of coway. But you got to makesure the filter or hepa filter is available after many many yrs.

I pay an expensive lesson when buy a korea air purifier. After sometime, no more selling and can't find the filter. Got to throw away the unit. Cost me RM2k for that stupid unit.

A bit expensive to use for RM60/mth.

Prefer own 1 which can last many yrs. The hepa filter can last at least 3yrs.

Standard air purifier should have hepa filter, filter and ionizer. The rest is sensor or anything gadget add in. Have the 3 function already good enough.

I don't run the unit 24hr or 8hr or 6hr. Just need to run 1hr interval or a little longer when the sensor turn green (detect good air). It doesn't have any benefit to keep running for long.

So 3yrs shouldn't be a problem. The main filter is require to clean more. That prolong the Hepa filter lifespan. The sensor will tell when the filter need to replace.

The sharp unit already been 8yrs and change 3x filter only. The Hepa filter cost RM200. If 60/mth x 12mth x 8yrs, I got to pay RM5760. That is a lot to breath a clean air. Just get a reliable brand that last long for your return.

The waterfall smell or forest smell is actually come from million of million of ion.

Those KCD is new model. KCA is old model.

Our climate is well humid. Humidifier need probably in aircon room only. If some ppl cannot stand the dryness or aircon set it too low in temp, than humidifier is necessary.

Cannot tahan anymore the haze. Wife also have some eye itchy because of haze. So go and shop for an air purifier. Expecting the price won't be cheap and doesn't have time to search more shop for cheap price.

I have use Sharp air purifier for 8yrs (office). It proof reliable and effective. So I get back another sharp model for my home. Have use other brand before like Philip, Medklin and don't no what brand korea made. All short lifespan or no filter replacement. But the sharp is the longest.

Already have mind to get the Sharp model KCD60EW or KCD40EW. But since the KCD60EW can cover 48m2 which is well over my living and dinner area, target at this model. Price is RM1920 from small electrical appliance shop. Lazada selling at RM1850, but sold out.

Front look


Back and side have 4 filter. Hepa, carbon and general filter. While the side is a humidifier with water container and humidifier filter. All the filter is easy access and clean. The filter can last 10yrs. But very much depend on the usage.


The front panel beside infor and switch also have air flow out. The red light showing some bad air and smell. Left is the ION ON/OFF and right is showing actual humid reading. It have 3 kind of function. Clean air, clean air with humidifier and haze mode. Others, ON/OFF timer, Fan speed, child lock, light off and OFF switch.


Another side have a label that you can write down the start usage date for the 3 filter. So till 2024 only need to change filter. Wonder can last that long.



This big model is not suitable for room. The mid and high fan speed is noisy. Measure with noise meter, the high speed fan can go 100db. Only the low speed is very quiet. Look freaking big also for small room.

My way of best using is
1) put the fan to auto, so the fan will choose itself when speed up.
2) Choose the clean air humid mode. Humidifier will ON when detect low humid. OFF when high enough.(Cannot select). That will save some power and no need everytime top up water.
3) Timer set to 2/4hr. That prolong the filter lifespan and save power. If a room is close, the air purifier don't need to be ON all the time. Once the air is clean detect, is can be switch OFF. Or run interval.

Thought you want to get a Coway?

Yes, I ON the ionizer once the unit is turn ON. But not run 24/7 lah. Once timer up, it will switch OFF everything.

Normally I place at the middle between the hall and the dinning area. Where the clean air blow out toward you. The menu said, 30cm from the wall. I don't no why the filter now design at behind. Ain't it suppose to suck air from front is more effective?

If put at the window, it suck air from outside and clean air blow out. But the filter is very fast dirty.

No timer to cut it off?

27w is more than 1 CFL light bulb running cost.

Beside that, when your room is already fill up with clean air, continue run doesn't have any advantage. Ain't it better this 27w extra be run on a light bulb ?

The filter lifespan is definitely shorten which is also the most expensive part.

If you decide to get a timer, 1yrs you already pay back your timer. RM12 from your running cost saving and the rest is from your saving in prolong the life of the filter.

When I brought the unit, I must state it have a timer. No timer, no buy.

I timer it 1hr before sleep. And delay ON 6hr after sleep. The filter can last 10yrs. Or filter replacement light ON. Which 1 come first.

Good idea also.

But I didn't do that. I have a small place. Too many unit is crowded the place.

I m lazy guy also. 1 more unit, more maintenance.

The ozone create is between the safe limit. They do have research on this what is the safe level and controlling.

You need million of million of ion to create something bad for your health.

You can read up on this --> http://www.medklinn.com/my/index.php?page=...ne-negativeions

Not just this side. Did read before others when I notice it. I did use this medklin before. The ozone is control in number of (forget the figure)

Already brought a Sharp air purifier. Some cincai review. --> https://forum.lowyat.net/topic/2111638/+280

Easy. Cause it famous air purifier and selling anywhere.

The old 1 cost RM200+. The new not sure. The filter can last for 10yrs. I wonder the unit can last that long or not.

I read from the manual. It did said 10yrs. But or course must follow maintenance lah.

All the filter can be clean. It have instruction how to clean and what to clean. It got state 1mth or sensor on.

Anyway I won't use till 10yrs also. Maybe around 7yrs change once. That already quite longtime for me.

Important is the filter still can get.
