Filtration Technology
The Nuwave uses a 3-stage filtration system: a pre-filter for large particles like pet hair and dust, an H13 True HEPA filter that captures 99.97% of particles down to 0.3 microns (including pollen, mold spores, and fine dander), and an activated carbon filter for gases, smoke, cooking odors, and VOCs. H13 is a medical-grade HEPA classification, placing this unit above standard HEPA filters found in many entry-level purifiers.
The combination means it handles both particulate and gaseous pollutants effectively.
Noise & Performance
CADR ratings come in at 104 CFM for smoke and 114 CFM for pollen, which is solid for a portable unit covering up to 857 sq ft of coverage area. At its lowest setting, the 16.5 dB noise output is virtually inaudible , well below the 25 dB threshold for whisper-quiet operation and quieter than roughly two-thirds of all purifiers on the market.
Even at maximum speed the noise stays at 37.7 dB, comparable to a quiet library, though some customers do note a noticeable jump to setting 3.
Smart Features & Controls
Controls are straightforward manual operation with 3 fan speeds , no touchscreen, app, or WiFi connectivity. This keeps the unit simple and reliable but means there's no auto mode to respond to changing air quality, no scheduling via smartphone, and no integration with Alexa or Google Home.
For users who prefer a plug-and-go approach without digital complexity, the simplicity is actually a plus.
Filter Maintenance
The replacement filter uses model number 47513, and Nuwave recommends regular replacement to maintain peak purification performance. The washable pre-filter helps extend the life of the main HEPA filter by catching larger particles like pet hair and visible dust before they reach the inner stages.
Customer feedback is mixed on filter installation ease , some find it straightforward while others report a learning curve, so referencing the manual during the first swap is recommended.
Who Is This Air Purifier For?
Ideal For
- ✓ Pet owners who need continuous odor and dander control , the carbon filter neutralizes pet smells while H13 HEPA captures fine pet hair and dander particles
- ✓ Allergy and asthma sufferers wanting medical-grade filtration , H13 removes 99.97% of pollen, dust mites, and airborne allergens
- ✓ Bedroom users who prioritize silence , 16.5 dB at the lowest speed is quieter than a library and won't disrupt sleep
- ✓ practical buyers wanting low operating investment , 12W Energy Star rating keeps electricity bills negligible
Not Ideal For
- ✕ Smart home enthusiasts , no WiFi, app control, or voice assistant integration means no remote monitoring or automation
- ✕ Users who want set-it-and-forget-it operation , without auto mode, you'll need to manually adjust speeds based on air conditions
- ✕ Whole-house coverage needs , while 857 sq ft is generous, a single portable unit won't handle multi-room purification simultaneously
Setup is minimal , remove the unit from packaging, unwrap and install the filter, plug in, and select your fan speed. The compact size and light 4.8 lb weight mean no assembly tools or complex positioning required.
Check the manual for correct filter orientation during initial installation, as some users report the fit can be snug
Place the unit with at least 12 inches of clearance on all sides for optimal airflow and purification performance
Nuwave typically offers warranty coverage on their air purifiers, but specific terms and duration for this model should be verified directly with the manufacturer or retailer at the time of purchase. The unit carries CARB, EPA, ETL, and Energy Star certifications, indicating it meets rigorous safety and performance standards.
FAQ
How quiet is the Nuwave air purifier at night?
At its lowest speed, the Nuwave runs at just 16.5 dB, which is quieter than a whisper and virtually inaudible in a bedroom setting. Most users report sleeping through the night without noticing it.
Even on medium speed, it remains well below conversational noise levels.
What size room can the Nuwave OxyPure Mini cover?
The Nuwave is rated for rooms up to 857 sq ft, making it suitable for large bedrooms, living rooms, and open-plan areas. For optimal purification with more air changes per hour, using it in rooms around 400-600 sq ft will deliver a strong option for results with its 114 CFM pollen CADR.
Does the Nuwave air purifier remove pet odors and pet hair?
Yes , the 3-stage filtration system is well-suited for pet owners. The pre-filter catches pet hair and larger particles, the H13 HEPA filter captures fine pet dander down to 0.3 microns, and the activated carbon filter absorbs pet odors.
Customers consistently report noticing a significant reduction in pet-related smells.
How often do I need to replace the filter?
The replacement filter (model 47513) should be changed according to Nuwave's recommended schedule, typically every 6-12 months depending on usage and air quality conditions. The washable pre-filter can be rinsed and reused, which helps extend the main HEPA filter's lifespan and reduces ongoing investment.
Does this purifier produce ozone?
No, the Nuwave is ozone-free and CARB certified, meaning it meets California's strict air quality standards. It uses purely mechanical filtration (HEPA and carbon) rather than ionization or UV methods that can generate ozone as a byproduct.
Can I control this air purifier with Alexa or a smartphone app?
No, this model uses manual controls with 3 fan speeds and does not include WiFi, app connectivity, or voice assistant integration. If smart home compatibility is a priority, you'll need to look at higher-end models.
However, the simple manual controls mean fewer things to malfunction and no dependency on internet connectivity.
