Field Controls Trio Plus (White, 5-Stage HEPA)

What room size can the Trio Plus effectively clean?

The Trio Plus cleans rooms up to 3300 square feet in one hour, or 1650 square feet in 30 minutes. This makes it suitable for large living rooms, open-plan offices, conference rooms and even small commercial spaces. The AHAM verified CADR rating of 305 CFM ensures reliable performance in these larger areas.

How does the 5-stage filtration system work?

The system uses a pre-filter for large particles, activated carbon for odours and gases, H13 HEPA for microscopic particles, dual UVC lamps for pathogen sterilisation and PRO-Cell technology for VOC breakdown. Air passes through each stage sequentially, ensuring comprehensive cleaning of particles, pathogens, odours and chemical pollutants.

What maintenance does the Trio Plus require?

Replace the pre-filter and carbon filter every 3-6 months depending on usage. The H13 HEPA filter typically lasts 12-18 months. UVC lamps should be replaced annually for optimal germicidal effectiveness. The PRO-Cell technology requires no maintenance. Filter replacement indicators help track when changes are needed.

Is the unit suitable for people with severe allergies?

Yes, the H13 HEPA filter captures 99.97% of particles as small as 0.1 microns, including pollen, dust mites, pet dander and mould spores. The UVC lamps provide additional protection against airborne allergens and pathogens. The automatic air quality sensor ensures consistent allergen removal without manual intervention.

How loud is the Trio Plus during operation?

The unit operates between 24.7dB and 52.8dB depending on fan speed. At minimum speed, it's quieter than a whisper, making it suitable for bedrooms. Even at maximum speed, noise levels remain comfortable for office environments. The automatic mode adjusts speed based on air quality, balancing cleaning power with noise levels.

Does the PRO-Cell technology produce ozone?

The PRO-Cell photocatalytic oxidation technology is designed to break down pollutants without producing harmful ozone. The unit is CARB certified, meeting California's strict air quality standards. The UVC lamps are also engineered for safe operation without ozone production, making it safe for continuous indoor use.

Can the Trio Plus eliminate smoke and cooking odours?

Yes, the combination of activated carbon filtration and PRO-Cell technology effectively neutralises smoke, cooking odours and other persistent smells. The carbon filter absorbs odour molecules whilst PRO-Cell technology breaks down volatile organic compounds at the molecular level, providing superior odour elimination compared to basic filtration alone.

What safety features prevent operation with missing filters?

The unit includes safety switches on the door and filter compartment that prevent operation unless all filters are properly installed. If filters aren't seated correctly or the door isn't properly closed, the unit won't turn on. This safety feature protects the motor and ensures optimal filtration performance by preventing bypass of the cleaning stages.
