# Molekule vs PuroAir

The clearest difference is review sentiment: PuroAir at 63% against Molekule's 17%. PuroAir also leads on rating (5.0 vs 4.4). Molekule's advantage is ratings volume (12K vs 4) and monetization model (free vs ad-supported). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
