Designed for the Alen A350 Air Purifier, the Alen HEPA-Pure Filter is a HEPA style replacement filter with Pre-Filter for dust and allergen removal.
We recommend replacing your filter every 6-12 months for severe concerns or when running your air purifier 24/7. Replace your filter every 12-18 months for light concerns or when running the air purifier only as needed. Rinse or lightly vacuum the removable black Alen Pre-Filter as soon as it develops a layer of visible particles. Allow it to completely dry before replacing. Washing or vacuuming the white HEPA style material will damage the fibers and is not recommended.
