Before You Buy at Alen
What shoppers ask most about Alen.
›Can I stack multiple discount codes on a single order?
Only one coupon code can be applied per order at checkout. Shoppers should choose the highest-value code available since codes cannot be combined with sitewide bundle promotions.
›Are there any exclusions for Alen promo codes?
Promo codes generally apply to air purifiers and select accessories, but they exclude active filter subscriptions and bulk Bundle & Save packages.
›What are the requirements to maintain the Forever Guarantee?
Alen offers a lifetime warranty on air purifiers, but it requires product registration and maintaining an active filter subscription.
›Can I modify or cancel my replacement filter subscription?
Filter subscriptions can be skipped, modified, or cancelled online at any time with no cancellation penalties before the next billing cycle.
