We offer a convenient replacement filter subscription program that is administered through our online store. In this program we ship you a replacement filter(s) every six (6) months.

Alen will, at its option, either furnish a replacement part or replace your air purifier provided the product is determined to be defective as a result faulty material or workmanship while in normal use. Replacement parts or units will be either new or refurbished. Alen's sole obligation under this warranty is to replace, or at Alen's discretion, to repair, free of charge, all defective parts.

All parts or units that are replaced become the property of Alen. To obtain warranty service, the defective product or part must be shipped or delivered to: Alen's authorized service center. All postage, insurance and shipping charges are the responsibility of the Purchaser and are not included in this warranty.
