How it brews

NextLevel's reusable steel discs drop into the base of the Pulsar (and Pulsar Mini) in place of the paper. Because it's an etched metal mesh, it micro-filters most of the sediment while letting more of the coffee's natural oils through, so the cup reads richer and bolder with more body than paper allows. The set pairs a denser 19k-hole disc — which can also sit under a paper filter as a body booster — with a cleaner 40k-hole disc. It's a one-buy, washable option; NextLevel publishes no within-seat flow rating, so we leave flow unrated rather than guess.

How it brews

NextLevel's flat-bottom paper cut for the Pulsar brewer, an 80 mm disc that also serves the Pulsar Mini. It's a brewer-specific seat, so this paper does not interchange with Kalita-Wave or other flat papers — it's shaped to the Pulsar's own bed. The flat disc lets the coffee stand in a shallow, even bed across the base, which is the geometry NextLevel designed the Pulsar around. NextLevel publishes no flow rating for the paper and there's no reliable within-seat ranking, so we leave flow unrated rather than guess. As a single-use paper it takes the usual rinse before brewing.
