Airwoods Ceiling Air Purifier

Our Advantages:

1. IFD (Intense Field Dielectric) filtration technology：

99.99% adsorption efficiency against PM2.5 particles. 3 step filtration. Filtering the particles (bigger than PM2.5) by pre-filter first. Smaller particles (≤PM2.5) go through the pre-filter will be treated by 12V field-charging and diffusion-charging. Finally, the charged particles will be attached on the IFD filter.

IFD filtration working principle：

An ifD air filter makes use of electric current to assist the removal of particulate pollution from air. Let’s break down the process into a three distinct steps.

1. Infusing electric charge into air：
The first step in the ifD air purification process is infusing the air with an electrical charge. This is similar to the process within an Air Ionizer. Once the electrical charge is introduced into the air, pollutants floating in the air pick up this charge and in effect they become ions since they are carrying a positive or negative charge on them.

2.  Passing air through filter：
The air carrying these charged pollutant particles is made to flow through the physical ifD filter. The ifD filter looks like a sheet with a honeycomb. These honeycombs are actually channels for the air to flow and are made of polymers.

3. Capture of pollutants by filter：
Between these many rows of polymer air channels there are thin sheets of electrodes. These thin electrode sheets generate a strong electric field which is capable of attracting the tiny particulate pollutants which are now charged. Since all the particulates are now charged, they are easily attracted towards the electrodes and as they migrate outwards, they get caught on the walls of the channels that they are passing through.

IFD Filtration Advantage:

A filter type that can be directly compared against ifD filters are the well known HEPA filters. HEPA stands for High Efficiency Particulate Air Delivery. HEPA filters are considered the gold standard when it comes to air purification today.
The main difference between HEPA and ifD filters is that HEPA filters need to be replaced once they are completely used up. ifD filters on the other hand can be used as a permanent filter. All that is required is to clean them every 6 months or so and they are back to their original state.
This has an obvious benefit for consumers as we do not have to shell out the cost of a replacement filter every few months with a traditional HEPA filter.
