Levoit Core 600S vs EverestAir-P

The Levoit EverestAir-P is better overall than the Levoit Core 600S, though the Core 600S is the better value if you care about air filtration performance alone. Their maximum particle filtration performance is practically identical, and the Core 600S even has a slightly higher maximum CADR. That said, the EverestAir-P is quieter, holds onto slightly stronger filtration at lower noise levels, and is better suited to spaces like bedrooms where you might not want to run the purifier at full speed. It also feels more premium, with a slimmer wall friendly shape, an adjustable air outlet, and a more advanced three channel laser particle sensor that gives you separate PM1.0, PM2.5, and PM10 readings.
