Which one from these models that i need to buy? Thanks.

Here view of my rent house, I'm not sure how large size of my living room. I think my living room not too big because I put a sofa on dining room, My living room enough fit for 8 people max with tv set cupboard and a small cupboard below stairs. By the way, when cooking, smoke and the smell can go through living room and dining room because this house straight long, not wide house. Even back door open during cooking, back door only open when want to cook only. For upstairs room A and B have the windows, if my next budget permitted, i want to put another one in room A. Room A much bigger a bit than Room B, have a queen size bed, 2 cupboard, 1 make up desk. Room A much easier got dusk even windows already closed and vacuum every week because winds flow directly into Room A if winds heavily before rain. Can sharp FPF30 suitable for Room A? For my living room, I think i need better model, Can models in the list fit enough handle the problem during cooking that smoke and smell? Even though some smell bed from dining room because frequently open front door.

From what i needed, at least cover for living room, if its can cover dining room too that will be fine for me, at least reduce the air impact especially in living room. In kitchen is simple, no hood and ventilation fan, so during cooking i switch on a big fan in the kitchen that flow the air direct to back door. So, i have reduced a bit of smoke. The owner don't want to add the hood or ventilation fan and the owner don't allow me to add these hood.

I need to vacuum 3 times every week for living room to reduce the dust, even though my daughter still have got flu and cough. So, i need to find these purifier at least its help a bit. So, do i need to buy two air purifier, one for living room and another one for dining room?

From what I searched in this website for dust, pollen and tobacco smoke I can see a few models above >450. So, this seem its inhale more right?

About CADR, some of it tell 165cfm(cubic feet per minute) and 330m3/h, so the higher mean better?

I will check it out soon, besides i need save more money to buy better air purifier.

I see..will check it out later..Thanks for clarification both of you..

what is the difference between humidifier and dehumidifier? which one better use in a room?

Thanks for clarification. my house no aircond even in room also no aircond. Only the fan, from what i can see dehumidifier have a storage behind it, is it water will fill automatically when use it? so, the water in that thing is contamination?
