I’m not very familiar with the situation in Nigeria, but my understanding is there’s a lot of dust in the air much of the year from the Sahara, plus in Lagos and other cities there’s a lot of pollution, is that right? In that case I wouldn’t recommend UVC at all (since it inactivates pathogens but doesn’t touch dust or pollution). Instead, something filter-based would have much broader benefits: dust and pollution in addition to pathogen control.
In the US the cheapest filter option is generally as Corsi-Rosenthal box (a box fan plus HVAC filters, both commodity items here). In Nigeria, something commercial would probably be cheaper since those aren’t everyday items. Looking online a bit, maybe the Acerpure Pro P2 at ~₦120,000 for 191 CFM CADR is best? While that’s a lot cheaper than the Aerolamp, though, that’s still out of reach for someone at ₦70,000 /​ month.

(Minor: the Aerolamp also uses Care222)
