No open air filter system interacts with more than a small volume of the air in a space!
So long as it cycles the air frequently enough, eventually it will capture particles proportional to its basic filtration capability.
- andbberger 6y agoYeah that's not true, diffusion exists.
- pjkundert 6y agoDiffusion is precisely why open-air filters (filters that draw in a portion of the air and filter it) work! The Dyson filter is an open-air filter, that draws a small sample of the air through a filter, and passes the rest through unfiltered. Each pass reduces the average (diffused) load of contaminants. Two identically effective filters with different flow rates will eventually achieve a specified target diffused contaminant load in the air in the space; the only difference will be the time taken to achieve this (given a fixed initial contaminant load). This should be clear...
- andbberger 6y agoI agree with the second statement, was disagreeing with 'only interacts with a small volume of air'
