What's the best air purifier for my house?

A really POWERFUL air purifier?..?

• Can anyone recommend a really powerful air purifier that isn't too expensive? Our house is very dusty as we only have time to clean it once a week, I don't know if having floorboards everywhere has anything to do with it my dust/dirt gets trapped there and my mother says that it makes the house smell more, we have a dog (Whom we wash regularly, but unfortunately being a dog is bound to get dirty and make the house smell like dog), and the smell of food seems to linger around the house until the day of cleaning. So any powerful air purifiers that could make my house smell nice all over again? Please don't recommend anything like Febreez, im looking specifically for an air purifier, thank you.

• Answer:

  The air purifier won't help with dust.. If your looking for inexpensive then you won't get a very nice one.. I have one that is about $500 in my room and it works wonderfully. You'll have to get one based on the size of your house and then based on price and quality. Go online and check out ones that specifiaclly mention what you need it for.
