This optional air-puriifying filter is used in addition to the filter included on Daikin mini-split systems. With its photocatalytic deodorizing function, this air purifying filter is able to trap microscopic particles, decompose odors and even remove bacteria and deactivate viruses. It features a large active surface area that effectively cleans the high volumes of air required to air-condition your rooms. The filter delivers consistent performance for approximately 3 years if regular washing (with water) is performed about every 6 months.
This filter is not a medical device. The benefits of absorption and decomposition of bacteria are only effective for substances that are collected on and in direct contact with the Air-Purifying Filter with Photocatalytic Deodorizing Function. It is for use with Daikin ductless mini-split systems that use wall-mounted indoor units.
Some codes in health care facilities require outside air venting all the time. This may take the place of that outside air requirement. I have run into this on PTAC units that were required to run all the time and also to have the vent blocked open. Since a mini split does not have outside air vents they may have purified the air with this filter to meet code.
