The NuWave OxyPure is a high-end air purifier. Its main selling point is its novel reusable filtration system, which uses washable pre-filters, 'Bio-Guard' filters, and pellet-type activated carbon filters that the manufacturer advertises to last 20 years without needing replacing. As befits a high-priced machine like this, the NuWave also boasts Wi-Fi connectivity and built-in particle sensors that allow it to change its fan speed depending on ambient air quality.
Our Verdict
The NuWave OxyPure is an excellent choice for pet owners. Its multi-stage filtration system allows it to trap a variety of particle sizes, and it has a sufficiently high clean air delivery rate to operate efficiently in larger rooms. While it's somewhat noisy at higher fan speeds, it's pretty quiet in its less powerful settings, which is good if you leave it running for extended periods with your pet at home.
- Quiet at lower fan speeds.
- Unique filtration system keeps costs of ownership low.
- Good clean air delivery rate.
- Impressive particle filtration.
- Has many filters that need regular cleaning.
The NuWave OxyPure air purifier is great for bedrooms, though perhaps a little much for smaller spaces, with a very high clean air delivery rate and excellent particle filtration. It can get a little loud at higher fan speeds, but it's pretty quiet for a machine of this size at lower settings. Its dedicated 'SLEEP' mode turns off the indicator lights but doesn't reduce fan speed, so you'll have to set that manually.

Popular Air Purifier Comparisons
The NuWave OxyPure is a high-end air purifier. Its closest natural competitor, in terms of sizing, price, and features, would be the Dyson Purifier Big+Quiet Formaldehyde BP04/BP03. The Dyson has the edge in terms of noise. That said, the NuWave purifier pulls ahead regarding actual particle filtration performance and incurs lower ownership costs due to its washable filters.

Test Results
The underside of this air purifier has a quartet of caster wheels that make it easy to roll around, at least on bare surfaces like vinyl or hardwood. You can see the wheels here.
This air purifier's display has separate indicator lights that show the status of its Wi-Fi connection and filter health. The 'Air' and 'Odor' dials are color-coded to give you a quick estimate of current air quality based on particulate matter counts and noxious gas levels, respectively. In descending order:
- Green
- Yellow
- Gold
- Orange
- Pink
- Red
There are also separate buttons to engage the 'Auto' mode, which allows the device to set fan speed depending on current air quality, 'Ultimate Clean' mode, which is similar to the 'Auto' function but defaults to the highest fan speed required, and 'Eco' mode, which causes the device to run the fan only when needed to save energy. The 'Turbo' mode sets the device to its highest fan speed for 1/2 an hour, one hour, or two hours. There's also a 'Timer' button that allows you to manually set the length of its operating in any mode: you can have it run for 1/2, two, four, eight, or 12 hours before turning off.
You can use the NuWave Connect App to remotely operate the air purifier, monitor current air quality, or check filter health.
The NuWave OxyPure has a somewhat novel filtration system. It consists of a stainless steel mesh pre-filter, two 'Bio-Guard' filters (which the manufacturer advertises to trap bacteria, mold, and viruses), an ozone removal filter, and a combination HEPA/pellet-type activated carbon filter.
The pre-filter, ozone filter, and bio-guard filter are washable and have an advertised lifespan of 20 years; you can clean the Bio-Guard and steel pre-filters under water every three to six months and every one to two months, respectively. However, you can't wash the ozone filter under water. Meanwhile, you're intended to replace the HEPA/Carbon filter after a year. You can find a replacement here.
