Overview

Features Deep-Dive

Large Room Coverage

WhisperMax Technology

Forever Guarantee

With a filter subscription, Alen guarantees the unit for life, they'll repair or replace it forever. This model invests Alen in product quality and creates genuine long-term value.

Without subscription, warranty is still strong at 3 years, but the Forever Guarantee creates compelling incentive to subscribe.

Pricing Analysis

Alen BreatheSmart 75i pricing runs $750-850. Filter subscriptions cost $50-70 quarterly depending on filter type. The Forever Guarantee requires ongoing subscription commitment.
