Several approaches to this one.
1. Dust covers for stuff you use.
Keep stuff you don't sealed in a covered container like it's box.
2. Vaccum clean regularly.
Once to twice a week minimum. DO replace the filters and bags as required.
3. Use a real HEPA filter.
The best quiet ones I've tried are IQAir HealthPro and BlueAir. IQAir ones are better, but they are more expensive too. Stay away from Sharper Image Ionic Breeze crap. They put out ozone. I tried the Ionic Breeze before, and it made me sick. They do jack squat to clean the air, they are odor neutralizers, NOT filters. It's simple physics. The Ionic Breezes do not move enough air to clean anything. If you really are concerned with removing cooking odors and smoke, the HealthPro Plus model has active charcoal filtration for gas filtration.
4. Take a Shower regularly.
Yes, it's gross but true. Skin cell flakes are everywhere, along with dust mite poo poo. Yikes.
