No WiFi/App Control
Cannot be controlled remotely via smartphone app
Why We Recommend It
- 01.
NCCO technology actively destroys pollutants through Nano Catalytic Oxidation rather than just collecting them on a filter, reducing secondary pollution risk
- 02.
H13 medical-grade HEPA filter captures 99.95% of particles at 0.3 microns including allergens, dust, and fine particulate matter
- 03.
Extremely quiet at 35 dB maximum , comparable to a soft whisper, making it usable in offices and hotel rooms without disturbance
- 04.
Ultra-lightweight at 2 lbs and compact dimensions (11.18 x 8.43 x 7.2 inches) make it genuinely travel-friendly for airplanes and hotels
- 05.
ETL Certified for electrical safety and draws only 1.3W , less power than a phone charger
Considerations
- 01.
Coverage limited to 108 sq ft , this is a personal-space purifier, not a room purifier, so it won't handle bedrooms or living areas effectively
- 02.
No smart features whatsoever , no WiFi, no app control, no auto mode, and no air quality sensor to adjust fan speed automatically
- 03.
Filter replacement every 3 months adds ongoing cost and requires more frequent maintenance than larger units with 6-12 month filter lives

Filtration Technology
The Westinghouse 1804 uses a dual-technology approach combining a True H13 HEPA filter with Westinghouse's patented NCCO (Nano Confined Catalytic Oxidation) system. The H13 HEPA filter captures 99.95% of airborne particles at 0.3 microns , the same grade used in medical settings , handling allergens, dust, bacteria, and fine particulate matter.
The NCCO technology takes purification further by using a nano-scale catalytic oxidation material to actively decompose trapped organic pollutants like bacteria, viruses, and VOCs into harmless carbon dioxide and water, rather than simply storing them on a filter where they can accumulate.
Noise & Performance
With a maximum noise level of just 35 dB, the Westinghouse 1804 is remarkably quiet , for reference, 35 dB is softer than most refrigerator hums and well below the 40-45 dB threshold that typically disrupts sleep or concentration. Coverage is rated at 108 sq ft, which positions this as a personal-zone air purifier rather than a room-scale unit.
No official CADR rating is published, which is common for ultra-compact portable purifiers in this size class, but the tight coverage area means air in the immediate vicinity cycles through the filtration system frequently.
Smart Features & Controls
This is an intentionally simple, manual-control purifier with no WiFi connectivity, no companion app, and no voice assistant compatibility. Fan speed is adjusted manually, and there is no auto mode or air quality sensor to dynamically respond to changing conditions.
While this limits convenience compared to smart purifiers, the simplicity is by design for a travel-oriented device , there is no setup process, no accounts to create, and no connectivity to troubleshoot in unfamiliar environments.
Filter Maintenance
Westinghouse recommends replacing the filter every 3 months, which is a shorter cycle than the 6-12 month intervals common on larger home air purifiers. This shorter lifespan is typical for compact units with smaller filter surface area processing air in close proximity.
The NCCO technology component is designed to be longer-lasting since it actively breaks down pollutants rather than accumulating them, but the HEPA pre-filter will need regular replacement to maintain optimal particle capture performance.
Who Is This Air Purifier For?
Ideal For
- ✓ Frequent travelers who want clean air in hotel rooms and on airplanes , the 2 lb weight and compact size fit easily in carry-on luggage
- ✓ Office workers wanting a personal desk purifier , 108 sq ft coverage handles a cubicle or immediate workspace, and 35 dB max won't disturb colleagues
- ✓ Allergy sufferers in small spaces who need H13 HEPA-grade filtration to capture pollen, dust mites, and fine particles at their desk or bedside
- ✓ Anyone concerned about bacteria and VOCs , the NCCO Nano Confined Catalytic Oxidation technology goes beyond standard HEPA by actively breaking down organic pollutants
Not Ideal For
- ✕ Anyone needing whole-room or whole-house coverage , at 108 sq ft, this won't purify a standard bedroom (typically 150-250 sq ft), let alone larger spaces
- ✕ Smart home enthusiasts who want app control, voice assistant integration, or automated air quality response , this is strictly manual operation
- ✕ Heavy smoke or strong odor removal , without a dedicated activated carbon filter layer, gas-phase pollutants and persistent odors are addressed primarily through NCCO rather than adsorption
Setup is virtually instant , remove the purifier from packaging, install the filter cartridge if not pre-installed, plug it in via the included power cable, and select your fan speed. The 1.3W draw means it can run off USB power sources, adding flexibility for travel use.
Run the purifier on the highest setting for 15-20 minutes when first arriving at a hotel room or new space to quickly cycle the immediate air before switching to a lower setting
Position the unit within 3-4 feet of your breathing zone for maximum personal air quality benefit given the 108 sq ft coverage area
The Westinghouse 1804 is ETL Certified for electrical safety standards. Specific warranty terms should be verified directly with Westinghouse or the authorized retailer at the time of purchase, as coverage periods may vary by seller.
FAQ
What is NCCO technology and how is it different from a regular HEPA air purifier?
NCCO stands for Nano Confined Catalytic Oxidation , it's a patented Westinghouse technology that uses a nano-scale catalytic material to actively break down organic pollutants like bacteria, viruses, and VOCs into harmless oxygen, carbon dioxide, and water. Unlike a standard HEPA filter that only traps particles, NCCO destroys them at the molecular level, which means the filter doesn't accumulate live bacteria or volatile compounds over time.
Can the Westinghouse 1804 purify an entire bedroom?
With a rated coverage of 108 sq ft, this purifier is designed as a personal-zone unit rather than a full-room purifier. Most bedrooms range from 150-250 sq ft, so the 1804 would be most effective on a nightstand close to your breathing zone rather than purifying the entire room.
How loud is the Westinghouse 1804 air purifier?
The maximum noise level is 35 dB, which is quieter than a whisper in a library (typically 40 dB). At lower fan speeds it's even quieter.
This makes it one of the quietest portable air purifiers available and suitable for use on a desk during work or on a hotel nightstand while sleeping.
Can I take the Westinghouse 1804 on an airplane?
Yes, the 1804 is designed specifically for travel portability. At just 2 lbs and measuring 11.18 x 8.43 x 7.2 inches, it fits in a carry-on bag or even a large personal item.
The 1.3W power draw means it can operate from USB power sources, though you'll want to check airline policies on running electronic devices during specific flight phases.
How often do I need to replace the filter and how much does it investment?
Westinghouse recommends filter replacement every 3 months under normal use. This is more frequent than larger home purifiers (typically 6-12 months) due to the compact filter size.
Replacement additions vary by retailer, so check current tier for the Westinghouse 1804-compatible filter cartridge when purchasing.
Does the Westinghouse 1804 remove cigarette smoke and cooking odors?
The NCCO Nano Catalytic Oxidation technology can break down some volatile organic compounds and gaseous pollutants associated with smoke and odors. However, without a dedicated activated carbon filter layer, it's less effective at absorbing heavy smoke or persistent cooking odors compared to purifiers with thick carbon filters.
For heavy smoke or odor removal, a larger unit with a substantial activated carbon stage would be more appropriate.

Bottom Line
The Westinghouse 1804 is a genuinely innovative portable air purifier that punches above its size class thanks to the patented NCCO technology working alongside H13 HEPA filtration. It's the right choice for travelers, desk workers, and anyone who wants medical-grade air purification in their immediate breathing zone without noise or bulk.
However, it's not a replacement for a room-scale purifier , if you need coverage beyond a small personal area, look at larger units.
Best for frequent travelers and office workers who want portable, whisper-quiet H13 HEPA purification with advanced NCCO pollutant destruction in their personal space
Consider alternatives if you need coverage beyond 108 sq ft, want smart features like app control or auto mode, or require heavy smoke and odor removal
