The Pre-filter’s job is to capture large particles the main filter usually can’t, or particles that get stuck to it. It prevents debris germs into the main filter, and this is why pre-filters come in handy as an additional strength in filter technology. Air Filter remove (from the air that passes through) 99.97% of particles that have a size of 0.3 µm (microns - A human hair has breadth of 12 microns). Carbon filters are special; they tend to capture more dirt and dust than standard filters. These pollutants are usually smaller and harder to catch they also eliminate unpleasant odours in the room. If you’re a smoker, or the house is filled with unwanted smells of any kind. Negative Ions clear the air of dust, mould spores, pollen, pet dander, odour’s, cigar smoke, bacteria and viruses. They do this by patching to these positively charged particles in large numbers. This causes the pollen, mould, bacteria, etc. to become too heavy to stay airborne.
