Filtration Technology
The OxyPure ZERO uses a dual 4-stage filtration system with a washable pre-filter designed to capture larger particles like pet hair, dust, and debris before air reaches the finer filtration stages. The standout here is the fully washable and reusable filter design , while most competitors require replacement filters every 6-12 months, Nuwave eliminates that cost entirely.
However, the absence of a dedicated activated carbon filter means it's less effective at trapping VOCs, smoke particles, and chemical gases compared to units with multi-layer carbon media. The unit is California Air Resource Board certified and EPA registered, confirming it meets air safety standards without producing harmful ozone , a concern with billions of airborne particles circulating in homes affected by air pollution.
Noise & Performance
At its lowest setting, the OxyPure ZERO produces just 21.4 dB , quieter than a whisper and virtually inaudible in a bedroom setting. This places it among the quietest 32% of air purifiers on the market.
With 2,002 sq ft of rated coverage and 6 speed settings, it can cycle air effectively through large rooms, though Nuwave doesn't publish specific CADR numbers, making direct performance comparisons difficult. Customer feedback confirms strong dust and general air quality improvement, though noise does increase noticeably at the higher speed settings.
Smart Features & Controls
The unit offers comprehensive controls including manual operation, WiFi connectivity, and a dedicated smartphone app for remote monitoring and scheduling. Auto mode uses onboard sensors to detect rising particle levels and adjust fan speed automatically , useful when cooking, vacuuming, or when seasonal allergens spike.
The adjustable vents at 30°, 60°, and 90° angles are a unique feature that lets you direct clean airflow where it's needed most, something few competitors offer. Sleep mode dims the display and reduces fan speed for undisturbed nighttime operation.
Filter Maintenance
This is where the OxyPure ZERO truly differentiates itself , every filter is washable and reusable, generating zero waste and zero ongoing investment. The pre-filter captures pet hair and large particles and can be rinsed clean under running water.
Nuwave recommends regular cleaning based on usage and environment, and the unit includes indicator alerts when maintenance is due. For homes with pets or in areas with heavy air pollution, more frequent washing may be needed to maintain peak performance.
Times between cleanings will vary based on air quality conditions in your area , homes dealing with headaches, congestion, or fatigue from poor indoor air quality may want to clean filters more frequently.
Who Is This Air Purifier For?
Ideal For

Not Ideal For

Setup is straightforward , remove the packaging, install the pre-filters (which come included), plug in, and connect to WiFi through the Nuwave app. Customers consistently report the unit is easy to set up and operational within minutes.
Run the unit on a higher speed for the first 24 hours to establish a clean air baseline in your space, then switch to auto mode for daily use

Nuwave typically offers warranty coverage on their OxyPure line, but specific terms and duration should be verified directly with Nuwave or at the point of purchase. Given the washable filter design, there are no consumable parts to worry about outside of the warranty period.
FAQ
How often do you need to wash the filters on the Nuwave OxyPure ZERO?
Nuwave recommends cleaning the washable filters based on your environment and usage. In homes with pets or heavy dust, you may need to wash them every 2-4 weeks.
The unit has a filter maintenance indicator that alerts you when cleaning is due. Simply rinse under running water, let them dry completely, and reinstall.
Can the Nuwave OxyPure ZERO remove cigarette smoke and cooking odors?
The OxyPure ZERO has limited effectiveness against smoke and strong odors because it lacks a dedicated activated carbon filter, which is the primary technology for absorbing gases and VOCs. It will capture smoke particles to some degree, but if smoke or odor removal is your primary concern, a purifier with an activated carbon stage would be a better choice.
Is the Nuwave OxyPure ZERO quiet enough for a bedroom?
Yes , at its lowest setting, it operates at just 21.4 dB, which is quieter than a whisper and virtually inaudible. The dedicated sleep mode further reduces noise and dims the display lights.
However, if auto mode kicks the fan to a higher speed during the night due to detected air quality changes, the noise will increase noticeably.
How much electricity does the Nuwave OxyPure ZERO use running 24/7?
The unit draws a maximum of 60W and is Energy Star certified for efficiency. Running continuously on a lower setting uses significantly less than the rated 60W.
S. electricity rates, expect roughly per month for 24/7 operation , and with zero filter additions, total operating expenses are minimal.
Does the Nuwave OxyPure ZERO produce ozone?
No. The OxyPure ZERO is California Air Resource Board (CARB) certified and EPA registered, meaning it meets strict standards for ozone emissions.
This is important because ozone can worsen respiratory issues , the CARB certification confirms this unit is safe for continuous home use.
What do the adjustable 30°, 60°, and 90° vents actually do?
The adjustable vents let you direct the clean air output at different angles , 30° for a wide, gentle spread across the room, 60° for a balanced mid-range flow, and 90° for a focused upward column. This lets you optimize airflow based on room layout and where you need the cleanest air directed.
