The catch
NuWave OxyPure Smart
Talk of washability can hide the fact that the HEPA-carbon combination still has to be replaced from time to time.
Side by side
NuWave OxyPure vs Honeywell HPA300: NuWave moves on wheels and runs schedules, Honeywell makes filter swaps simpler
Quick verdict
NuWave is the pick for wheels, app automation and washable auxiliary stages. Honeywell is the pick for a simpler route to certified HEPA, clear AHAM numbers and consumables that are easier to find.

What this page compares
Two high-airflow floor units go head to head on automation, washable stages, certified HEPA status, noise and filter cost.
This one comes down to independent airflow and controls first, then to the limits of your own setup.
Day to day
How each one fits your routine
Reusable stages swap buying filters for a cleaning routine
Several stages on the OxyPure are washable, but its HEPA-and-carbon main stage is still a replacement part. The HPA300 uses three HEPA cartridges and a carbon prefilter. Choose OxyPure if you are willing to take out, clean and dry the right reusable stages on a regular basis. Choose Honeywell if a routine built around replacement is more practical. Do not pick either on the assumption that every filter can be rinsed or that washable stages remove all recurring costs.
Where this comes from
The comparison is of the tasks left once you've bought it. How many stages are reusable is not a measured lifetime-cost result, and permission to clean covers only the components that are specifically washable.
A room used for many calls may favor setting the fan deliberately
If predictable fan behavior matters, put either purifier on a manual level you choose before a call. Honeywell has physical fan controls and a timer. OxyPure adds sensing, Auto mode and remote adjustment for times when you are somewhere else. Choose Honeywell if that local manual routine covers what you need. Choose OxyPure when automatic response or remote changes help. Neither control scheme proves quieter operation at equivalent clean-air delivery.
Where this comes from
Each can hold a fixed setting. The extra controls on the OxyPure count when nobody is in the room, and a fan change driven by the sensor during a call is a different operating condition from a level you fixed on purpose.

It will be cleaning an open living area
NuWave OxyPure Smart lists “About 323 CFM measured” for independent airflow, while Honeywell HPA300 lists “About 305 CFM measured”. Extra published output only helps when your room, surface or workload needs the headroom. On its own, it does not prove better results.

Plug in your numbers
Can either purifier keep up with your room?
This checks hard limits only. Personal preferences are left out of the math.
NuWave OxyPure Smart
Check this one yourselfWe do not have a comparable verified smoke CADR for this exact model.
Honeywell HPA300
Works with your numbers300 CFM of verified clean-air delivery works out to about 7.5 air changes per hour in this room. Hitting the 5 ACH target takes 200 CFM.
This uses each model’s pollutant-specific CADR at top speed and a target of five air changes per hour. Quieter settings clean less air. Raw airflow and one-change coverage claims are never swapped in.

Spec by spec
Where they really differ
| Spec | NuWave OxyPure Smart | Honeywell HPA300 | In practice |
|---|---|---|---|
| Independent airflow | About 323 CFM measured | About 305 CFM measured | Higher published output is useful only if your room, surface or workload calls for the extra headroom. It does not, by itself, prove better results. |
| Controls | Sensors, Auto and app | Manual speeds and timer | For controls, this shapes setup and day-to-day use more than the core physical job. |

Trade-offs
What each pick costs you
With NuWave OxyPure Smart
- Weighing about 26.5 pounds, it relies on its wheels, and the cabinet takes up quite a bit of floor space.
With Honeywell HPA300
- At high airflow it is among the louder options, with RTINGS measuring roughly 39 to 60 dB.
