I’m comfortable to report that Burtran’s declare was right—its operation didn’t end in a spike of radioactivity. My whole residence was measuring round 20 clicks per minute, or CPM—for context, 5-50 CPM is regular background. It’s when the quantity hits over 2,000 that the GQ GMC Geiger Counter Nuclear Radiation Security Information says to evacuate and report it to the federal government.

Filter Fortitude
Burtran additionally claims that, with its beefed-up HEPA 14 filters, the Nano-Oxy “captures 99.995 p.c of ultra-fine particles right down to 0.1 micron, surpassing HEPA 13 effectivity by as much as 90 p.c.”
HEPA is an acronym for “high-efficiency particulate air.” The quantity that follows HEPA is the MERV score, or minimal effectivity reporting worth, which measures a filter’s potential to seize particles between 0.3 and 10 microns. Because the EPA explains, “The upper the MERV score, the higher the filter is at trapping particular varieties of particles.”
There’s a catch to all that density, although—in sure home equipment, MERV 14 can limit airflow. For instance, DIY air purifiers just like the Corsi-Rosenthal Field suggest MERV 13 filters, not MERV 14. The air flowed freely out of the Nano-Oxy, so I wasn’t capable of verify if this was the case with this explicit machine. There’s an indicator gentle that alerts when the filter must be changed; the dirtier the air, the earlier the filter will should be modified. Alternative filters price round $100.
To Sleep Mode or To not Sleep Mode

The Burtran Nano-Oxy packs a big punch in its foot-and-a-half by foot-and-a-half physique. At 17.5 kilos, it’s straightforward to maneuver with its two facet handles, however it may possibly successfully clear the air the advisable 5 occasions an hour in a 270-square-foot room. I often see that sort of room-cleaning energy from bigger home equipment. It additionally has an activated carbon filter to seize risky natural compounds (VOCs) and a prefilter to seize bigger particles like pet hair. The entrance steel mesh comes off simply to entry the filters. The management panel has a timer, fan velocity, auto and sleep modes, and three diploma angles—30, 60, and 90—that management the three slats for airflow path from the highest of the equipment. The Burtran works with the Sensible Life app, which has one of many best dashboards to make use of and pair.
I’ll all the time suggest utilizing the auto setting, as an air air purifier’s built-in air sensor is aware of when to regulate the fan velocity; this may be a difficulty for air purifiers within the bed room, as the very best setting creates essentially the most noise. It’s that purpose, noise, that the majority air purifiers have a sleep mode possibility.
