I operate Lucky Miner LV06 units, which feature a robust metal casing and an adorable bitcoin-themed cooling fan. To enhance their utility, I've fitted a HEPA filter atop the unit, enabling it to double as an air purifier by filtering out dust. While this modification may not guarantee a windfall in bitcoin mining, it does ensure the air I breathe is purer. However, it's worth noting that the addition of the filter slightly restricts airflow, resulting in the miner operating at a temperature approximately 2 degrees Celsius higher than it would without the filter.
