Product Overview
The Nuwave Oxypure Zero E500 Air Purifier is engineered for whole-house air cleaning in large rooms, covering up to 966 ft² in roughly one hour. Utilizing a patented Bio-Guard 3-stage washable filter system, it captures particles down to 0.1 microns with third-party lab certification. The unit is ozone-free and meets CARB, ETL, and Energy Star standards, ensuring compliance with stringent environmental and safety requirements.
Key to its design is an intuitive sensor that constantly monitors air quality, indicated by a 6-color LED ring. Users can select from 6 fan speeds and three operational modes—Auto, Sleep, and Manual—to balance airflow and noise. In Sleep Mode, the purifier dims its display and drops noise to as low as 22 dB, quieter than a whisper.
Connectivity is handled through the Oxypure mobile app, available for iOS and Android. With Wi-Fi control, you can remotely adjust fan speed, set timers, and view real-time AQI data. The app also logs historical air quality trends, helping households track improvements over days or weeks.
The Bio-Guard filters are ozone-free and fully washable—an eco-friendly alternative to disposable HEPA filters. Rinsing them under running water or using canned air keeps maintenance simple and cost-effective. Replacement filters for this model carry a modest price, but many users report extended lifespans through regular cleaning.
Construction is solid, with a compact form factor that fits most corner or tabletop placements. While some competitors add caster wheels, the E500 relies on its 16-inch diameter base for stability. The control panel includes clearly labeled buttons for Power, Mode, Speed, Timer, and Wi-Fi status.
In summary, the Oxypure Zero E500 aims to deliver powerful purification in large spaces without hidden emissions or proprietary filter traps. Its combination of performance, certification, and washable components positions it as a strong contender in the high-end air purifier market.

Nuwave Oxypure Zero E500 Review: Honest Findings
After analyzing product specs, customer feedback, and certification data, we find that the Oxypure Zero E500 strikes a fine balance between performance and user convenience. The third-party tested filtration data is credible, with reported capture of 99.99% of particles ≥0.1 μm. Certifications from CARB, ETL, and Energy Star further validate its claims.
In real-world use, heat, cooking fumes, pet dander, and pollen are effectively reduced within 30–60 minutes in large rooms. Users in kitchens and living rooms report noticeable odor removal and dust reduction. The intuitive LED color ring accurately reflects pollution spikes, changing from green to red when cooking or vacuuming.
On the flip side, the unit’s maximum fan speed can reach around 60–65 dB—comparable to a normal conversation. While most users run the device at levels 1–3 for daily use, occasional bursts at speed 6 can be distracting for some. Sleep Mode remedies this with a silent 22 dB setting.
Maintenance is straightforward thanks to washable Bio-Guard filters. Users praise the cost savings over disposable HEPA elements, though a minority note that filters require a full 24 hours to dry completely to avoid mold or mildew risks.
Smart features perform reliably, but a few customers mention occasional Wi-Fi dropouts in congested networks. Rebooting the router or re-adding the device in the app resolves the issue. Firmware updates are delivered automatically, but manual refresh is also available.
In comparing price points, the E500 sits above entry-level purifiers but below luxury commercial units. For the combination of certified performance, app control, and washable filters, many find the investment justified.
Overall, our honest assessment is that the Oxypure Zero E500 offers serious air cleaning power for large spaces with minimal hidden downsides. No major safety incidents or design defects have surfaced in public databases or user forums.
- High praise for effective purification and washable filters.
Positive Feedback & Highlights
A majority of customers (19 mentions) emphasize the Oxypure Zero’s effectiveness at removing smoke, dust, and pet dander. Those with indoor smokers or multiple pets note faster odor elimination than with previous units.
Seven reviews highlight the device’s air purification prowess, stating the air feels noticeably fresher within hours. One customer wrote, “The air quality monitoring seems to work well. The color definitely changes when we are cooking or if the vacuum is run kicking up dog hair.”
Ease of setup earns consistent praise. With seven mentions, customers describe unboxing to operation in under five minutes—no tools or complicated filter installation required.
Washable filters are another standout. Seven customers cite the convenience and cost savings of Bio-Guard technology over disposable HEPA filters. “Having filters that are washable is a big plus,” one user stated.
Size and form factor garner positive feedback as well. Four out of five mentions on “Size” applaud its compact design. Although some wish for caster wheels, the overall footprint blends easily into home or office decor.
Functionality gets three thumbs up for multiple fan speeds, timer settings, and app control. The included Oxypure app receives commendations for its intuitive layout and real-time AQI updates.
Several users mention the ultra-quiet Sleep Mode, reporting restful nights without white-noise disturbances. Most agree the lowest speed setting remains nearly silent.
- Noise complaints at max speed are the main negative point.
- No evidence of serious rumors or hidden defects.
Negative Reviews & Rumor Analysis
While the Oxypure Zero E500 draws overwhelming positive feedback, some concerns emerge. The most frequent issue (8 mentions) is noise level at the highest fan setting. A few users liken it to a hairdryer, prompting them to stick with speeds 1–3.
One customer remarked, “It can be noisy when it’s running on its highest level, so it tends to only be run on that level if we aren’t going to be in the same room.” For those requiring silence around the clock, the Sleep Mode setting is the recommended workaround.
Price sensitivity appears in a handful of reviews, with some questioning the $300+ asking price. However, most acknowledge that washable filters offset the upfront cost over time.
A minor design gripe involves the absence of wheels or casters, making relocation slightly cumbersome for some users. Complaints are few and generally described as “wish list” items rather than deal-breakers.
No serious complaints about safety, emissions, or reliability have surfaced. Rumors of ozone generation or hidden carbon filters are unfounded—this model is CARB-certified for ozone emissions well below EPA limits (<1 ppb).
No recalls, product advisories, or official safety incidents are recorded by regulatory bodies. Certification data and lab reports remain publicly accessible, dispelling any notion of exaggerated performance claims.
In summary, the only persistent negatives relate to maximum noise, price, and a lack of caster wheels. Beyond these minor points, there is no evidence of harmful rumors, safety hazards, or widespread defects.
- Ideal for large rooms, allergy sufferers, and pet owners.
Who Should Consider Nuwave Oxypure Zero E500?
If you occupy a large living space (up to 966 ft²), the Oxypure Zero E500 is tailored to maintain air purity quickly. Families in open-plan homes, loft apartments, and communal offices will benefit from its high CADR and rapid circulation.
Pet owners particularly stand to gain, as multiple users highlight the device’s ability to tackle pet dander and litter dust. Those with cats, dogs, or birds can expect noticeable reductions in airborne hair and odors.
Allergy sufferers and asthmatics will appreciate the sub-micron filtration efficiency. Certified removal of PM2.5 and VOCs makes this purifier well-suited for sensitive individuals prone to pollen or dust mite reactions.
The Oxypure app integration appeals to tech-savvy buyers who want remote control and data tracking. For homeowners wanting smart home synergy, the device pairs well with voice assistants and routine automation.
Budget-minded consumers should note the higher initial investment, though washable filters help amortize costs over years. If you rarely need to maximize airflow, you’ll find the lower fan speeds both quiet and energy-efficient.
Commercial users—such as salons, gyms, or classrooms—may also adopt this model for its robust performance and certification pedigree. Its streamlined maintenance ensures minimal downtime and operating expense.
- No critical issues detected; strong overall value.
- Minor noise and price caveats notwithstanding, we recommend it.
