The Nano-Oxy air purifier from Burtran just cleared two big hurdles: it kept background radiation steady at 20 CPM and squeezed true HEPA-14 performance into a 1½-foot cube.
Radiation Check
Derrick M. Collins parked a Geiger counter beside the machine for several hours. Readings stayed within the normal 5-50 CPM window, never approaching the 2,000 CPM evacuation threshold. Burtran’s claim that the unit “does not emit harmful radiation” held up.
Filter Claims
Burtran says its HEPA-14 cartridge grabs 99.995 % of ultra-fine particles down to 0.1 micron-about a 90 % jump over typical HEPA-13. Key points:
- HEPA-14 equals MERV 14 on the EPA scale
- Dense media can choke airflow in DIY boxes; the Nano-Oxy kept a smooth stream
- A light warns when the $100 replacement is due
Daily Use
Weighing 17.5 lb, the unit sports side handles and auto, sleep, and timer modes. The Smart Life app pairs quickly and lets users steer the 30°, 60°, or 90° top vents from a phone.
| Room Size | Air Changes/Hour | Max Fan Noise |
|---|---|---|
| 270 sq ft | 5 | Noticeable on high; near-silent in sleep |
An activated-carbon layer tackles VOCs, while a washable pre-filter grabs pet hair. Derrick M. Collins recommends the auto setting so the onboard sensor ramps up only when needed.
Key Takeaways
- Zero radiation increase verified in a real-world apartment test
- HEPA-14 filter offers MERV-14 capture without the usual airflow penalty
- Compact footprint still hits five air changes per hour in a typical bedroom
If you need hospital-level filtration but lack floor space, the Nano-Oxy delivers clean air-and peace of mind-without the racket.
