Disposable N95 or reusable half-face respirator: which should I buy?

Across the reviewers we read, the answer depends on use. For occasional dust, allergens, or short tasks, a NIOSH-approved disposable N95 like the 3M 8210 is cheap and effective. For repeated work involving solvents, paint fumes, or fine sanding, specialist-community consensus (notably r/Masks4All and r/woodworking) favors a reusable elastomeric half-face with replaceable cartridges, citing better long-term cost, easier breathing, and a more verifiable seal.
