CPD Event - Technical Visit to NanoFIL Filter Factory and R&D Laboratory

Registration starts at 2:00pm on 22 March 2023 (Wednesday)

Limited seats. First come, first served.

This event is organised by the Hong Kong Green Building Council.

Is there any HVAC filter that has a high filtration efficiency and a low pressure drop, while the frequency of replacement is reasonably low? This will eliminate a lot of landfill waste and reduce the costs spent on HVAC operation and maintenance.

NanoFIL Sterilizing Nano-Filter is one of the innovative technologies listed in EMSD’s E&M InnoPortal, which is able to achieve the above objectives. It can be made as a 2” thick mini-pleated filter that can easily fit into the size of most AHUs in buildings.  More importantly, it can totally replace a 2” pre-filter and a 12” metal box filter/bag filter, thus achieving a big saving in installation space. This is made possible because of the use of nano-fibre electrospinning technology, and the composite filter material combines nano-fibres and electrostatic fibres together, with unique air purification ability. The efficiency is better than other air filtration products on the market, and the pressure drop is also lower than the traditional pre-plus-primary filter sets. Further details can be found at:

The concerned company, Nanofiltration Technology Ltd, is a local company that received Innovation & Technology Fund from the Government and joined the HKSTP Incubation Programme in 2016. It also conducted an R&D project with NAMI for the development of sterilizing nano-filter using nano-technology.

Their factory is located in Tsuen Wan. It is equipped with state-of-the-art electro-spinning machine for nano-fibre membrane production, ultrasonic stitching machine, pleating machine and a laboratory for R&D. In particular, there is a filter testing rig to EN 779 standard. Filtration efficiency and pressure drop of air filters can be tested in a couple of minutes.  During this visit, participants will have a chance to look at these advanced manufacturing facilities.
