More moisture!
These filters work and fit perfectly in the Honeywell humidifier.And I believe that they put moisture into the air than the factory Honeywell filters. Also I can say that they are easier to clean, and more durable, at a much lower price.

Best Iâve used
Very good filter with large surface area for greater evaporation. Other brands Iâve purchased in the past seem to have changed their manufacturing process and are making the filters smaller and as a result they donât release as much moisture.These filters have performed exceptionally well.

Fit
They fit my older humidifiers and work well.
Jean-Pierre St-Denis –
Ce filtre est utilisé pour un humidificateur Honeyweel compact. Il fonctionne sur plusieurs modèles. Et il est à bon prix. Malheureusement, il est pratiquement impossible de le détartrer à cause de sa fragilité (les filtres dâorigine ont le même défaut).
