Gents,

Need some advice.

I am looking for 2 different kind if air purifier:

1. For small bedroom (Size 10m2). In the room have a very bad sewerage smell from behind the house that sometime the smell spread through other room from the that room.

2. For my kitchen. It's a bit dusty (and of course sometime smelly)

So I'm looking some air purifier that don't cost me too much and maintenance wise, easy to find the filter and long lasting filter would be very good.

I've seen this Sharp KCD-40EW or KCG model air purifier. Their filter can last for up to 10 years But the cost once change is around RM200++

Another option that I've seen is the Philips model AC1215 the filter can last only about 2 years but the initial price is a bit lower. Same goes to Mi 2s purifier

But above may suitable for my kitchen as it covers big area. I'm afraid if I put into that bedroom its a waste of its potential.

However, for my bedroom i found this AUGIENB A-DST02. Does anyone know how frequent the filter need to be changed?

And is it to have less headache about the bedroom air purifier maintenance, I just take the air purifier like that sharp or philips above and put into the room?

Thanks in advance.
