Hi missosoup, Lio here, co-founder of Neoplants. At this point we are not considering subscriptions for Neo P1, only bundles to keep things simple. When it comes to that article quote, it is referring to the 4 pollutants we are targeting: Benzene, Toluene, Xylene and Formaldehyde, which are the 4 main Volatile Organic Compounds commonly found in houses, highly carcinogenic and very hard to eliminate (not just capture). You can learn more about that on our Product Page here: https://neoplants.com/product
