Westinghouse 1804 Portable Air Purifier Review: Clean Air Anywhere You Go

After spending three weeks with the Westinghouse 1804 Portable Air Purifier, I’m convinced it’s a game-changer for travelers and anyone concerned about air quality. This compact powerhouse combines patented NCCO Technology with True HEPA filtration to create what might be the most effective portable air purifier I’ve tested this year.

Breathe Easier with Advanced Purification Technology

The standout feature of this Westinghouse air purifier is undoubtedly its patented NCCO (Nano Confined Catalytic Oxidation) Technology. Unlike standard purifiers that simply trap particles, the NCCO system actually destroys harmful substances at a molecular level. During our testing in a hotel room that had lingering smoke odors, the difference was noticeable within just 30 minutes of operation.

Comprehensive Protection Against Invisible Threats

What impressed me most was the Westinghouse 1804’s ability to tackle virtually every airborne concern:

• Viruses and Bacteria: The NCCO technology actively eliminates these pathogens rather than just trapping them
• VOCs (Volatile Organic Compounds): Those invisible chemicals from cleaning products, paints, and furnishings don’t stand a chance
• Allergens: Pollen, dust mites, and pet dander are efficiently captured by the True HEPA filter
• Smoke and Odors: Perfect for hotel rooms with lingering smells or plane cabins with recirculated air

Price: $129 - $79.99

Perfect Travel Companion: Take Clean Air Anywhere

During our testing, we took this purifier on a cross-country flight and to multiple hotel rooms. Here’s why it excels as a travel companion:

• Truly Portable Design: Measuring just 6.9 x 6.9 x 7.6 inches and weighing 3.5 pounds, it fits easily in carry-on luggage
• USB-C Powered: Works with power banks, laptop chargers, and hotel outlets without adapters
• Whisper-Quiet Operation: At 35dB on low setting, it won’t disturb your sleep
• Coverage Area: Effectively purifies spaces up to 120 sq ft – perfect for hotel rooms, offices, or RVs

Real-World Performance That Impressed Us

During our allergy season testing, we placed the Westinghouse 1804 in a bedroom with a known dust mite problem. The morning stuffiness and sneezing that typically plagued our tester was significantly reduced after just one night. The unit’s small size is deceptive – it packs serious purification power.

Smart Features That Enhance the Experience

Beyond its core purification capabilities, the Westinghouse 1804 includes thoughtful features that made our testing experience even better:

• Filter Replacement Indicator: No guesswork about when to change filters
• 3 Fan Speeds: Adjust according to air quality needs and noise preferences
• Night Light Function: Soft illumination option is perfect for unfamiliar hotel rooms
• 360° Air Intake: Efficiently draws air from all directions for better purification

Energy Efficiency That Won’t Drain Your Devices

When powered through a laptop USB-C port during our travel testing, the purifier barely affected battery life – drawing just 8W at its highest setting. This efficiency makes it practical for extended use while traveling without worrying about finding a power outlet.
