Where reviewers disagree The two reviews split on setup and overall framing: TechHive calls the setup needlessly lengthy with onerous security and pitches the unit as gargantuan, commercial-grade gear that dominates a room, whereas TechRadar calls setup effortless (~5 minutes), the design discreet, and recommends it for large homes.

The Alen BreatheSmart 75i is nothing if not powerful. In fact, the unit is so punchy that it can create a breeze across a moderately large room, which may be more than most home users need.

The unit is whisper-quiet at its lowest speed, but in automatic mode I found the unit rather aggressive at ratcheting up the speed, even when particulate levels were low.

The lengthy setup process includes more onerous security than my bank account

While there are plenty of air purifiers on the market, most of them don't come with the power of the Alen BreatheSmart 75i.

you could probably buy seven smaller air purifiers for the cost of one Alen BreatheSmart 75i.

They ran the Alen BreatheSmart 75i and it got rid of a lot of stale air. However, the smell of cigarettes did linger a little.

Source: alen.com (verified 2026-07-07) · corroborated by amazon.com. alen.com product page confirms 1,400 sq ft optimal coverage (purifies up to 2,800 sq ft every hour / 1,400 sq ft every 30 minutes), noise 25 dBA lowest to 51 dBA highest speed, Energy Star certified (Energy Star "Yes" and 2025 'Most Efficient'), medical-grade True HEPA (H13) filtration with a switchable Ionizer (Ionizer "Yes"; can be turned on/off), Advanced Particle filter across tiers, optional carbon layer on Advanced (Fresh)/Ultimate (Odor) filters, and WiFi/Alen Air app control with PM2.5/TVOC/eCO2/temp/humidity sensors, at $799.00 (regular = sale price). The page lists an unlabeled "CADR 375" that equals the Turbo airflow figure (speed breakdown 100-375 CFM) and does not publish an AHAM smoke-specific CADR, so cadr_smoke_cfm is left null. The Amazon US listing (ASIN B0F99DHRV7, model "BreatheSmart 75i_V2") corroborates HEPA filtration, up to 2,800 sq ft coverage, 0.1-micron capture, App control, and Energy Star + CARB certification (its price shown only in localized EUR, not used for USD). No fetched page states an explicit model release year (Amazon "Date First Available: May 20, 2025" is an availability date, not a stated release), so releaseDate and the release spec are null. All non-null values re-verified verbatim on the fetched pages; exact model confirmed (75i, not 45i/35i/25i siblings).
