most average only 1 year lifetime or less with decreasing efficacy over time, have to replace the entire system when it’s spent, adds to electricity cost when in use, and you need to install a lot of them for it to be effective because when run at too high power levels they produce large amounts of hazardous ozone
I think this is true for many options, but not the Aerolamp:
It is built around the Ushio Care222 B1. This is a long-lasting design, rated for 10,000 hours before falling below 70% output. That’s one year of 24⁄7 usage, five years of working hours, or much longer if run less often.
They do use electricity, but at 11W it’s a negligible 1-2¢ per hour.
Even one Aerolamp cleans a lot of air. You can model efficacy with Illuminate.
Well filtered lamps do not produce a lot of ozone. Unless your building is incredibly well sealed ozone levels would go up if you opened a window. If you’re very concerned you can run an air purifier that includes an activated carbon layer, which many do.
Thanks for clarifying! I do think in a context like this one, where people are thinking about why offices etc don’t install far-UVC, your friend’s phrasing is likely to confuse people. For example, if I recommended someone not buy a car because it only had a one-year lifespan, I think they’d be grumpy if they later learned I meant it would only last one year of 24⁄7 operation. When we talk about “lifespan” we’re normally bringing in assumptions about expected usage.

Hi Jeff, I think we’re talking about the same lifespan, my friend was talking about 1 year of continuous use (he works in industrial applications).
