On low, the Blast uses just 64W of electricity. If you run your Blast 8 hours a day, that’s just 15kWh of energy per month. In the US, that would equate to a running cost of roughly $3. On high, the Blast uses approximately 90W of power, which is 22kWh of energy per month, or $4.30.
Compared with other purifiers, the Blast provides more clean air, with less energy, less noise, and a longer lifespan. All for a lower up-front cost.
