3. electric screen pack: use filter fiber, utilize electric field intensity micro particle catching efficient, in the situation that identical filter efficiency, the electro static filtering material can obtain lower crushing, but the extra procedure for processing of the identical need of electric screen pack is assisted, and adds as batch mixing and static and holds etc. (increase production cost); If without the above-mentioned processing of process, its filter efficiency obviously descends, loss in efficiency is up to 75%, therefore peace and quiet for setting out with personal security and air filtration, electro static filtering net initial characteristic also can't represent minimum efficiency in operating process, more can't corresponding air filtration or CADR index properties, and no matter future is because of factors such as physics or chemistry, may cause screen pack static to lose efficacy, cause that filter screen pollutant matter is disengaged again and wait dangerous, like this lose the purpose of air cleaning device utilization.
4. the ESP filtration system utilizes high potential to carry out the air ionization, carry out removing of dust to have charged collecting plate again, the influence factor of this system effectiveness comprises potential difference, electric field pole apart from and run through speed etc., be generally and make the ESP system reach a degree micro particle filtering efficient, can adopt and improve potential difference or shorten the electric field pole distance, thereby causing the ESP system to have high ozone has problems, and the problems such as the corona quenching or scintillation easily occur, therefore need have the professional and carry out the periodic maintenance maintenance, and the material cost of using high (approximately more than ten times of price differentials of adhesive-bonded fabric filter).
5. in addition, at present family expenses ESP system can't pass through UL toxotest (ozone test) mostly, but install a non-removable potassinm permanganate filter additional in the ESP system in recent years, high ozone concentration when operating to reduce ESP, but this screen pack list has catalyst property with regard to ozone, therefore, apply to poison and obstruction under general environment, so do not popularize in the household application market.
So its structure of traditional air cleaning device is needed improvement badly.
