Smart WiFi Connected
App control and monitoring (125 out of 932 purifiers have WiFi)
Auto Mode with Air Quality Sensor
Automatically adjusts fan speed based on real-time air quality readings
Energy Star Certified

Considerations
HEPA-Type (Not True HEPA)
HEPA-type filter may not capture as many fine particles as True HEPA
Why We Recommend It
- 01.
Washable, reusable filters save significant money over time compared to purifiers requiring -60 replacement filters every 6 months
- 02.
Exceptionally quiet at 21.4 dB on the lowest setting , quieter than a whisper and barely audible in a silent room
- 03.
Full smart home integration with WiFi app control, scheduling, and real-time air quality monitoring from your phone
- 04.
Dual odor sensors enable auto mode to detect and respond to pollutants in real time across 6 fan speeds
- 05.
Compact 13.2 lb design with a small 9.5" x 11" footprint fits easily on a shelf or nightstand
Considerations
- 01.
Uses HEPA-type filtration rather than True HEPA (H13), which may capture fewer ultrafine particles below 0.3 microns , a trade-off for the washable filter design
- 02.
No dedicated activated carbon filter stage, limiting effectiveness against smoke, cooking odors, and volatile organic compounds
- 03.
No published CADR rating makes it harder to compare raw air-cleaning speed against competitors head-to-head

Filtration Technology
The Oxypure Zero uses a 3-stage HEPA-type filtration system with a washable pre-filter that captures large particles like pet hair and dust before air reaches the main filter, which Nuwave claims removes 99.9% of particles down to 0.1 microns. It's important to note this is HEPA-type rather than True HEPA (H13), so independent capture rates at the critical 0.3-micron particle size are unverified.
The washable design is the key differentiator , most competitors in this category require filter replacements every 6-12 months, while the Oxypure Zero's reusable filters just need periodic rinsing.
Noise & Performance
At its lowest setting, the Oxypure Zero produces just 21.4 dB , quieter than a soft whisper and among the quietest in its class, with only about a third of all purifiers hitting below 30 dB. The unit covers up to 966 sq ft, positioning it for medium to large rooms, though without a published CADR rating it's difficult to calculate precise air changes per hour. For bedroom use, the combination of 21.4 dB minimum noise and a dedicated sleep mode that dims the display makes it one of the better choices for undisturbed rest.
Smart Features & Controls
This is a fully connected house purifier with WiFi and a dedicated smartphone app for remote control, scheduling, and air quality monitoring , a feature found in only about 13% of purifiers on the market. The dual odor sensors feed into an auto mode that adjusts fan speed across 6 levels based on real-time pollutant readings, so the unit ramps up when it detects changes and quiets down when air is clean.
Additional controls include a timer, sleep mode, and an onboard air quality indicator for at-a-glance status without opening the app.
Filter Maintenance
The standout maintenance feature is the washable, reusable filter system , simply remove, rinse, dry, and reinstall instead of buying replacements. The washable pre-filter handles the heavy lifting of trapping large pollutants like pet hair and dust, extending the main filter's effective life.
A filter change indicator lets you know when cleaning is needed, and customers report the cleaning process is straightforward and quick.
Who Is This Air Purifier For?
Ideal For
- ✓ Bedroom sleepers who need near-silent operation , the 21.4 dB low setting with dedicated sleep mode won't disturb light sleepers
- ✓ practical buyers tired of recurring additions , washable filters mean no replacement purchases for the life of the unit
- ✓ Smart home enthusiasts who want app-based scheduling, remote monitoring, and auto mode that adjusts to real-time air quality
- ✓ Pet owners in medium to large rooms , the pre-filter catches pet hair and dander while covering up to 966 sq ft
Not Ideal For
- ✕ Smoke or strong odor sufferers , without an activated carbon filter, this purifier has limited gas and VOC absorption for heavy smoke or cooking pollutants
- ✕ Allergy sufferers needing hospital-grade filtration , True HEPA (H13) purifiers capture 99.97% of particles at 0.3 microns vs. the HEPA-type filter here
- ✕ Buyers who prioritize verified CADR numbers , no published CADR makes it difficult to confirm air changes per hour in your specific room size
Setup is minimal , remove the packaging, install the washable filters (they may ship separately inside the unit), plug in, and connect to WiFi via the Nuwave app. Customers consistently report the unit is easy to set up and operational within minutes.
Run the purifier on its highest speed for the first hour to clear any initial manufacturing odors, then switch to auto mode for daily use
Place the unit at least 12 inches from walls for optimal airflow across the full 966 sq ft coverage area
Nuwave typically offers a manufacturer's warranty on their Oxypure line , verify current coverage and duration directly with Nuwave or your retailer at the time of purchase, as terms may vary.
FAQ
How often do you need to wash the reusable filters on the Nuwave Oxypure Zero?
Washing frequency depends on usage and air quality in your home. In a typical household, cleaning the filters every 2-4 weeks keeps performance optimal.
The unit has a built-in filter indicator that alerts you when it's time to clean, so you don't have to guess.
Is the Nuwave Oxypure Zero loud enough to disturb sleep?
No , at its lowest setting it produces only 21.4 dB, which is quieter than a whisper and virtually inaudible. The dedicated sleep mode further reduces noise and dims the display lights, making it one of the quietest purifiers available for bedroom use.
Can the Nuwave Oxypure Zero remove cigarette smoke and cooking odors?
It has limited effectiveness against smoke and strong odors. The 3-stage HEPA-type filtration captures smoke particles, but without a dedicated activated carbon filter, it won't absorb gaseous pollutants and VOCs as effectively as purifiers with carbon filtration.
For heavy smoke or cooking odor removal, consider a purifier with an activated carbon stage.
Is the Nuwave Oxypure Zero a True HEPA air purifier?
No, it uses HEPA-type filtration rather than True HEPA (H13). Nuwave claims 99.9% removal of particles down to 0.1 microns, but HEPA-type filters are not held to the same independent testing standard as True HEPA.
For most rooms and typical household pollutants, it performs well, but allergy sufferers requiring certified medical-grade filtration may want a True HEPA model.
How big of a room can the Nuwave Oxypure Zero cover?
It's rated for rooms up to 966 sq ft, which covers most living rooms, master bedrooms, and open-plan spaces. For optimal performance in larger rooms, place the unit centrally with clear airflow paths rather than in a corner.
Does the Nuwave Oxypure Zero work with Alexa or Google Home?
The purifier features WiFi connectivity and a dedicated smartphone app for remote control and monitoring. Check the latest Nuwave app documentation or product listing for current smart home platform compatibility, as integrations can be updated via firmware.
