IFD filter is an invention patent from Darwin Company in the UK, belonging to electrostatic precipitator technology. It is currently one of the more advanced and efficient dust removal technologies available. The full name of IFD in English is Intensity Field Dielectric, which refers to a strong electric field using dielectric materials as carriers. And IFD filter refers to a filter that applies IFD technology.
IFD purification technology actually utilizes the principle of electrostatic adsorption. Simply put, it ionizes the air to make dust carry static electricity, and then uses an electrode filter to adsorb it, thereby achieving purification effect.
Main advantages:
High efficiency: capable of adsorbing almost 100% of airborne particles, with an adsorption efficiency of 99.99% for PM2.5.
Safety: By using a unique structure and discharge method, the problem of ozone exceeding the standard that may occur in traditional ESP technology has been solved, reducing the risk of electric shock.
Economy: The filter can be cleaned and reused, with low long-term operating costs.
Low air resistance: Compared with HEPA filters, the air resistance is lower and does not affect the air supply volume of the air conditioner.
Low noise: Low operating noise, providing a more comfortable user experience.

Advantages |
Disadvantages |
|
|
HEPA filter |
Good single filtration effect, price friendly |
The resistance is high, and the filter needs to be replaced regularly, resulting in high costs in the later stage |
|
Activated carbon filter |
Having a large surface area, it can fully contact and adsorb with air |
It cannot adsorb all harmful gases, with low efficiency |
|
Electrostatic precipitator |
High filtration accuracy, recyclable water washing, electrostatic sterilization |
There is a hidden danger of excessive ozone, and the filtration effect decreases after a period of use |
|
IFD filter |
The filtration efficiency is as high as 99.99%, with no risk of ozone exceeding the standard. It can be washed with water for recycling and sterilized by static electricity |
Need cleaning, not suitable for lazy people |
