Looking for a powerful air purifier that can handle allergens, viruses, smoke, odors, and more—all in one unit? The TRIO Plus 5 Stage Portable Air Purifier might be exactly what your home needs.
In a world where indoor air quality affects everything from allergies to long-term health, a quality air purifier isn’t a luxury anymore—it’s essential. That’s why I took a deep dive into the TRIO Plus by Field Controls—a model that’s not only certified by major health and safety agencies but has also proven itself in independent lab tests against airborne viruses like SARS-CoV-2.
Here’s everything you need to know to decide if the TRIO Plus is the right purifier for your space.
🌬️ What Makes the TRIO Plus Stand Out?
Unlike budget air purifiers that rely on a single HEPA filter, the TRIO Plus features five powerful layers of defense:
1. Washable Pre-Filter
Captures larger particles like hair, dust, and pet dander. It’s washable, meaning you’ll save on replacement costs over time.
2. Activated Carbon Filter
Neutralizes common household odors from cooking, pets, smoke, and chemical gases (VOCs).
3. H13 HEPA Filter
This hospital-grade filter captures 99.97% of particles as small as 0.1 microns, including mold spores, pollen, and other allergens. Ideal for asthma and allergy sufferers.
4. Dual UV-C Germicidal Lamps
Powerful UV-C light destroys airborne bacteria and viruses, including COVID-19, influenza, and mold.
5. PRO-Cell™ Photocatalytic Oxidation (PCO)
This advanced technology breaks down VOCs into harmless water vapor and CO₂, giving you deeper chemical neutralization than carbon filters alone.
🔬 Lab-Tested Results: Independent testing showed a 99.99% reduction in SARS-CoV-2 in 30 minutes and similarly high reductions in other airborne pathogens. Few consumer-grade purifiers can make that claim.
Coverage, CADR & Performance
- CADR (Clean Air Delivery Rate):
- Dust: 305 CFM
- Smoke: 305 CFM
- Pollen: 329 CFM
- Coverage:
- Up to 3,300 sq. ft. (1 air change/hour)
- Up to 1,100 sq. ft. (3 air changes/hour)
Whether you’re purifying a large bedroom, open-concept living room, office, or classroom, the TRIO Plus has the capacity to handle it.
How Quiet Is It?
The TRIO Plus runs as quietly as 24.7 dB on low, comparable to a whisper. Even on high settings, it maxes out around 52.8 dB, which is still quieter than a normal conversation. Users report it being nearly unnoticeable at night—though like any high-powered unit, you’ll hear a slight hum at full speed.
Smart Features That Make a Difference
- Real-Time Air Quality Sensor
Automatically adjusts fan speed based on current air conditions, helping you save energy and maintain cleaner air without manual adjustments. - Filter & Lamp Replacement Alerts
Built-in indicators let you know exactly when it’s time for maintenance.
Easy Maintenance + Cost Breakdown
| Component | Frequency | Estimated Cost |
|---|---|---|
| Pre-Filter (washable) | Every 1–3 months (cleaning) | $0 |
| Filter Set (HEPA + Carbon) | Every 6 months | $56–$100 |
| UV-C Lamps (2) | Every 12 months | $38–$78 |
Maintenance is straightforward, and the washable pre-filter cuts down on recurring costs.
