The Field Controls 602605100 is the OEM replacement filter kit for the TRIO Plus portable air purifier, covering all three filtration stages in a single purchase. Keeping these filters fresh is what keeps the TRIO Plus performing at spec — skipping replacements degrades airflow, filtration efficiency, and UV effectiveness.
The kit includes a pre-filter, an H13 HEPA filter, and an infused activated carbon filter. The pre-filter handles coarser particles down to 5 microns, extending the life of the downstream filters. The H13 HEPA filter captures airborne allergens, dust, dander, and fine particulates down to 0.3 microns at 99.97% efficiency — medical-grade classification. The activated carbon filter addresses what the HEPA can’t: odors, VOCs, and common household chemical smells are adsorbed rather than just trapped.
Field Controls recommends replacing the filter set every 6 months under continuous 24/7 operation, with frequency adjusting based on actual usage and indoor air quality conditions. The UV lamp is sold separately and is not included in this kit.
