03 — Why compatible, done right

Off-brand isn't the risk. The wrong model is.

A generic HEPA filter is fine — a generic filter that doesn't seal in your housing is not. The whole job is the match. We build the model⁠×⁠part table from manufacturer documentation, name the exact unit each part fits, and never sell you a "universal" that fits nothing well.

One thing we won't sell yet

Drinking-water filters. Generic fridge and pitcher cartridges need NSF/WQA certification we haven't sourced. We publish which cartridge fits your model — but we won't put a compatible drinking-water filter on the shelf until we can stand behind the safety. See the reference data →
