A study on the penetration of particle across a newly formulated filter aids material known as PrekotAC (combination of an adsorbent, activated carbon and pre-coating material, PreKot™) on PTFE filter media was carried out in a laboratory scale filtration test system. PrekotAC was evaluated based on the total penetrated particles across its filter cake under constant material loading of 0.2 mg/mm² and three different air flow rates of 4, 5 and 6 L/min. The ratio of total penetrated particles with and without the introduction of filter aids was observed and results showed that PrekotAC is capable to increase the collection efficiencies of ambient air particles compared to the performance of PTFE filter media alone. It was also found that PrekotAC has a better particle collection efficiencies compared to its original raw material activated carbon alone with PrekotAC 10:90 gives the lowest particle penetration among other combination of PrekotAC materials.
