VOLZ Luftfilter GmbH & Co. KG, has been a valuable development partner of the Nanosynth Group, established over 55 years with impressive R&D and in house testing and development facilities.
Volz Luftfilter GmbH is a vertically integrated filter company with state-of-the-art manufacturing facilities producing polyester and polypropylene media, for use in filtration products. This includes face masks, heating, ventilation, and air conditioning (HVAC). Volz are without doubt the ideal partner to integrate our anti-pathogenic technology into filter media.
In partnership with Volz, Virosynth has made significant strides and developed new application technologies that facilitate the use of Pharm2Farm’s nanotechnology within their production facilities.
This enabling technology will be translated to any media manufacturer wishing to licence and adopt it.
Which has resulted in the creation of anti-pathogenic filter medias, specifically developed to combat the spread of bacteria and viruses including Covid -19.
The Reality is
A good MERV 8 or ISO 16890 ePM-Coarse filter will achieve a 75% arrestance of particles at 5 µm exactly in the contaminated particle range.
Large scale air conditioning generally has two stages of filtration, prefilters as above MERV 8 or ISO 16890 ePM-Coarse followed by a secondary filter targeted at the removal of finer contaminants down to 0.3-1 µm, purposely used in stages to strain out contaminants.
We believe it is important that end users of these products are advised that both stages of filtration however ustilised, should be anti-pathogenic to abait the spred of bacteria and viruses and to protect the individuals changing the filters.
What does this mean for the HVAC industry?
The most accepted recommendation is that air filters should achieve an average efficiency of 50% or better at 0.3 – 1 micron particle size to be affective at removing airborne pathogens.
This means filters of MERV 13 or ISO 16890 ePM1 50% or better should be used.
However, a vast amount of comfort air conditioning systems currently utilise much lower standards of filtration typically MERV 8 or ISO 16890-1:2016 ePM-Coarse filtration and are not suitable for upgrade to filters with higher efficiencycommonly known as pre-filters.
