Air purifier for dusty room removes dust from the air all the day long. But, vacuum cleaner cleans up dust only several times in a month. It depends on how much time you have to do that.
So, how does Honeywell HHT-011 captures dust from the air? Basically, there is three step filtration processes inside the unit.
First, dusty air will be cleaned by a washable pre-filter, where large air-borne particles are separated. At the second stage, the air will be filtered by HEPA filter. At this stage, 99% of dust and other particles will be removed from the air. And at the last stage, cleaned air comes into ionizer. The ionizer provides extra cleaning process and makes air fresher.
