Burtran Nano-Oxy Smart Air Purifier: Safe Sleep?
I am happy to report that Burtran’s assertion was correct: its operation did not result in a spike in radioactivity. My entire apartment measured around 20 clicks per minute, or CPM. For context, 5-50 CPM is a normal background. It is when the number reaches more than 2,000 that the GQ GMC Geiger Counter Nuclear Radiation Safety Guide recommends evacuating and reporting the problem to the government.

Filter courage
Burtran also claims that, thanks to its reinforced HEPA 14 filters, the Nano-Oxy “captures 99.995% of ultrafine particles down to 0.1 microns, exceeding the efficiency of HEPA 13 by up to 90%.”
HEPA is the acronym for “high efficiency particulate air”. The number after HEPA is the MERV rating, or Minimum Efficiency Reporting Value, which measures a filter’s ability to capture particles between 0.3 and 10 microns. As the EPA explains: “The higher the MERV rating, the more effective the filter is at trapping specific types of particles. »
There’s a problem with all this density, however: In some appliances, MERV 14 can restrict airflow. For example, DIY air purifiers like the Corsi-Rosenthal Box recommend MERV 13 filters, not MERV 14. The air flowed freely out of the Nano-Oxy, so I couldn’t confirm if that was the case with this particular machine. There is an indicator light that alerts when the filter needs to be replaced; The dirtier the air, the sooner the filter will need to be replaced. Replacement filters cost around $100.
To go to sleep mode or not to go to sleep mode

The Burtran Nano-Oxy packs a big punch in its foot and a half by foot and a half body. Weighing 17.5 pounds, it’s easy to move thanks to its two side handles, but it can effectively purify the air five times per hour recommended in a 270 square foot room. I usually see this kind of room cleaning power coming from larger devices. It also has an activated carbon filter to capture volatile organic compounds (VOCs) and a pre-filter to capture larger particles like pet hair. The front metal mesh easily detaches to access the filters. The control panel has a timer, fan speed, auto and sleep modes, and three-degree angles (30, 60, and 90) that control the three slats for the direction of airflow from the top of the unit. The Burtran works with the Smart Life app, which has one of the easiest dashboards to use and pair.
I will always recommend using the automatic setting, because an air purifier’s built-in air sensor knows when to adjust the fan speed; This can be a problem for in-bedroom air purifiers, as the highest setting creates the most noise. It is for this reason, noise, that most air purifiers have a sleep mode option.
