Westinghouse 1701 Air Purifier: Detailed Spec Analysis
The Westinghouse 1701 stands out with its proprietary NCCO (Nano Confined Catalytic Oxidation) technology paired with a medical-grade H13 HEPA filter, offering a 4-stage filtration system that goes beyond standard air purification by actively breaking down pollutants rather than just trapping them. It's a compact, EPA-certified home air purifier best suited for small rooms up to 300 sq ft, making it a solid pick for bedrooms, nurseries, or home offices where allergen and dander control matters most.

Filtration Technology
The Westinghouse 1701 uses a 4-stage filtration system anchored by a medical-grade H13 HEPA filter that captures 99.95% of particles at 0.3 microns , this includes fine allergens, bacteria, and airborne particulates that lower-grade HEPA filters miss. What differentiates this unit is the NCCO (Nano Confined Catalytic Oxidation) technology, which actively oxidizes and breaks down gaseous pollutants and volatile organic compounds at a molecular level rather than simply adsorbing them like activated carbon.
The washable pre-filter serves as the first line of defense, trapping larger particles like pet hair and household dust to extend the lifespan of the inner filters.
Noise & Performance
The Westinghouse 1701 is rated at 37 dB, which is roughly equivalent to a whisper or quiet library , suitable for bedroom use without significant sleep disruption. Coverage is rated for rooms up to 300 sq ft, making it appropriate for standard bedrooms, home offices, or nurseries.
For context, most competing small-room purifiers in this class operate between 25-55 dB, placing the 1701 on the quieter end of the spectrum, though customer feedback is mixed with some users reporting it's quieter than expected while others find it noisier than the spec suggests.
Smart Features & Controls
This is a manual-control purifier with no WiFi connectivity, no companion app, and no voice assistant integration. Fan speed adjustment is done directly on the unit, and there is no auto mode or built-in air quality sensor to trigger automatic speed changes.
While this simplicity means zero setup hassle and no dependency on cloud services, it does mean you lose the convenience of scheduling, remote control, and real-time air quality monitoring that smart-enabled competitors offer.
Filter Maintenance
The outer pre-filter is washable, which reduces ongoing costs and helps protect the inner H13 HEPA and NCCO filters from premature clogging. The NCCO technology has an advantage over traditional carbon filters in that it regenerates during operation rather than saturating over time, potentially extending its effective lifespan.
Users should check the manufacturer's guidance for recommended replacement intervals on the H13 filter, and look for the filter change indicator to know when replacement is due.
Who Is This Air Purifier For?
Ideal For
- ✓ Allergy and asthma sufferers , the H13 HEPA filter captures 99.95%+ of common triggers including pollen, dust mites, and mold spores
- ✓ Pet owners in small spaces , the pre-filter traps pet hair while the H13 filter handles fine dander particles
- ✓ Bedroom or nursery use , the compact footprint and quiet operation at 37 dB make it unobtrusive for sleep environments
- ✓ Anyone who prefers simple, no-fuss operation , straightforward manual controls with no app setup or connectivity required
Not Ideal For
- ✕ Smart home enthusiasts , no WiFi, no app, no voice assistant integration means it operates completely independently
- ✕ Large room or whole-house coverage , at 300 sq ft capacity, you'd need multiple units for spaces beyond a single room
- ✕ Heavy smoke or cooking odor removal , while the NCCO technology helps with some odors, dedicated activated carbon filters in competing models handle smoke and strong odors more aggressively
Setup is straightforward , remove the unit from packaging, take out the filters from their sealed plastic wrapping, install them back into the purifier in the correct order, and plug in. No tools, no app pairing, and no WiFi configuration required.
Run the purifier on its highest fan speed for the first 1-2 hours in a closed room to quickly establish clean baseline air quality
Place the unit at least 12-18 inches from walls and furniture to ensure unobstructed airflow on all sides
Westinghouse is a well-established brand with customer support infrastructure in the US. Specific warranty terms for the 1701 model should be verified directly with Westinghouse or the authorized retailer at the time of purchase, as coverage periods and conditions may vary.
FAQ
What is NCCO technology and how is it different from a regular carbon filter?
NCCO (Nano Confined Catalytic Oxidation) is Westinghouse's proprietary air purification technology that actively breaks down gaseous pollutants and volatile organic compounds at a molecular level through catalytic oxidation. Unlike activated carbon filters that trap and hold pollutants until they saturate, NCCO continuously regenerates, meaning it doesn't lose effectiveness over time the way carbon filters do.
Is the Westinghouse 1701 quiet enough for a bedroom?
At 37 dB, the 1701 operates at a level comparable to a quiet whisper or soft ambient noise, which is generally considered sleep-friendly. However, customer feedback is mixed , some find it impressively quiet while others report it louder than expected, so noise perception may vary depending on your sensitivity and room acoustics.
How often do I need to replace the filters on the Westinghouse 1701?
The outer pre-filter is washable and reusable, so you won't need to replace that. The H13 HEPA filter should be replaced according to the manufacturer's recommended schedule, typically every 6-12 months depending on usage and air quality conditions.
The NCCO filter has a longer lifespan due to its self-regenerating catalytic technology. Watch for the filter change indicator on the unit.
Can the Westinghouse 1701 remove cigarette smoke and cooking odors?
The NCCO technology does help break down some gaseous pollutants and odors at a molecular level, and the H13 HEPA filter captures smoke particles. However, for heavy smoke or persistent cooking odors, purifiers with large activated carbon filters and higher CADR ratings tend to perform more aggressively.
The 1701 provides limited smoke and odor control compared to dedicated smoke-removal models.
Does the Westinghouse 1701 work with Alexa or Google Home?
No, the Westinghouse 1701 does not have WiFi connectivity or smart home integration. It operates with manual controls only.
If smart home compatibility is a priority, you'll need to look at WiFi-enabled purifiers from brands like Levoit, Coway, or Blueair.
Is 300 sq ft of coverage enough for my living room?
The 300 sq ft rating works well for standard bedrooms, home offices, and small living rooms. If your living room is larger than 300 sq ft or part of an open floor plan, the 1701 will still clean the air but won't achieve as many air changes per hour as needed for optimal filtration.
For larger spaces, consider a purifier rated for 500+ sq ft or use the 1701 as a supplemental unit.

Bottom Line
The Westinghouse 1701 earns its place as a capable small-room air purifier thanks to the combination of medical-grade H13 HEPA filtration and the proprietary NCCO technology that actively destroys pollutants rather than just collecting them. It's an excellent fit for allergy sufferers and pet owners who want straightforward, effective air purification in a bedroom or office without dealing with apps and connectivity.
Skip it if you need large-room coverage, heavy smoke removal, or smart home integration.
Best for allergy and pet dander control in bedrooms and small rooms up to 300 sq ft
Consider alternatives if you need smart home integration, auto mode with air quality sensing, or coverage beyond 300 sq ft
