Filtration Technology
The OxyPure Ultra uses a 5-stage filtration system anchored by a True HEPA filter that captures 99.97% of airborne particles down to 0.3 microns, including pollen, dust mites, mold spores, and pet dander. The activated carbon filter stage tackles VOCs, smoke, cooking odors, and chemical fumes, while the washable pre-filter handles larger debris like pet hair and household dust.
This multi-layer approach is more comprehensive than the typical 3-stage systems found in most competitors, and the inclusion of 4 extra HEPA filters in the box is uncommon at any tier.
Noise & Performance
With 2,934 sq ft of coverage, this unit can purify the air in extra large rooms and open-concept spaces , placing it in the top tier for residential purifiers. The minimum noise level of 31.4 dB in sleep mode is comparable to a quiet library, making it suitable for bedroom use overnight.
However, customers consistently note that higher fan speeds (the unit offers 6 total) produce significantly more noise, so expect a trade-off between maximum air circulation and quiet operation in shared living areas.
Smart Features & Controls
The OxyPure Ultra offers WiFi connectivity with a dedicated smartphone app for remote monitoring, scheduling, and speed adjustments , a feature found in only about 13% of purifiers on the market. Auto mode uses a built-in air quality sensor to dynamically adjust fan speed based on real-time readings, while sleep mode dims the display and drops to the quietest setting.
Additional controls include a timer, 6 manual speed settings, and an air quality indicator light, giving you granular control whether you prefer hands-on or set-and-forget operation.
Filter Maintenance
The pre-filter is washable, which saves on recurring costs and keeps the primary filters working efficiently by catching large particles first. The inclusion of 4 extra True HEPA filters in the box is a standout , most competitors ship with just the installed filter, making this a strong value proposition for long-term ownership.
A filter change indicator alerts you when replacement is needed, taking the guesswork out of maintenance scheduling.
Who Is This Air Purifier For?
Ideal For
- ✓ Allergy and asthma sufferers , True HEPA filtration captures 99.97% of pollen, dust mites, and dander at 0.3 microns across large spaces
- ✓ Pet owners in big homes , activated carbon filter neutralizes pet odors while HEPA captures fine dander and hair particles
- ✓ Smart home enthusiasts , WiFi connectivity, app scheduling, auto mode, and air quality indicators integrate into connected routines
- ✓ Office managers or open-plan living , 2,934 sq ft coverage handles air circulation in expansive commercial or residential areas
Not Ideal For
- ✕ Small apartment dwellers , the 26 lb, 14.25" x 26.25" footprint and large-room CADR are overkill for spaces under 500 sq ft
- ✕ Noise-sensitive users who run purifiers on high , while sleep mode hits 31.4 dB, higher speeds are noticeably louder according to customer feedback
Setup is straightforward , remove the unit from packaging, unwrap and install the included filters into their designated slots, and plug in. WiFi pairing through the app takes a few minutes and enables remote control and air quality monitoring right away.
Run the purifier on a higher speed for the first 1-2 hours to clear any initial manufacturing odors and establish baseline air quality readings
Connect to WiFi during initial setup so auto mode can begin calibrating to your space immediately
Nuwave typically backs their OxyPure line with a manufacturer warranty, but specific coverage terms and duration should be verified directly with Nuwave or checked at the point of purchase, as warranty details can vary by retailer.
FAQ
How often do I need to replace the HEPA filters on the Nuwave OxyPure Ultra?
Filter life depends on usage and air quality, but the unit includes a filter change indicator that alerts you when replacement is needed. The box comes with 4 extra True HEPA filters, so you're covered for an extended period before needing to purchase replacements.
Is the Nuwave OxyPure Ultra quiet enough for a bedroom?
In sleep mode, it operates at just 31.4 dB , roughly the level of a quiet whisper , which is comfortable for sleeping. However, at higher speeds the noise is noticeably louder, so bedroom use works best with sleep mode or lower fan settings enabled overnight.
Can the Nuwave OxyPure Ultra really purify the air in a 2,934 sq ft area?
The 2,934 sq ft rating represents the maximum coverage area with adequate air circulation. For optimal air changes per hour in heavily polluted spaces, you'll get a strong option for performance in rooms closer to half that size.
In cleaner environments or open-plan areas, the full coverage rating is achievable.
Does the Nuwave OxyPure Ultra work with Alexa or Google Home?
The unit features smart WiFi connectivity with a dedicated app for remote control, scheduling, and monitoring. Check the current product listing or Nuwave's app documentation for the latest smart home integration details, as voice assistant compatibility can be updated via firmware.
How well does the OxyPure Ultra remove pet odors and dander?
The 5-stage filtration system is specifically effective for pet owners. The True HEPA filter captures 99.97% of pet dander particles at 0.3 microns, the carbon filter absorbs pet odors, and the washable pre-filter traps pet hair before it reaches the main filters.
Customer feedback consistently highlights its effectiveness at eliminating pet-related odors.
How much electricity does the Nuwave OxyPure Ultra use?
The unit draws up to 125W at maximum speed and is Energy Star certified, meaning it meets strict energy efficiency standards. On lower speeds and sleep mode, power consumption drops significantly.
Running it 24/7 on a moderate setting typically costs just a few dollars per month on most electricity plans.

The 5-stage system with True HEPA, bundled extra filters, and WiFi app control make it a strong long-term value for allergy sufferers, pet owners, and smart home users.
If you're in a smaller space or need whisper-quiet operation at all speeds, a more compact model may serve you better.
Best for pet owners and allergy sufferers in large homes or offices who want comprehensive 5-stage filtration with smart WiFi control
