Alen BreatheSmart Air Purifiers

The BreatheSmart family is the core air-purifier lineup from Alen.

Current models include:

• BreatheSmart 75i
• BreatheSmart 45i
• BreatheSmart 35i
• BreatheSmart 25i

The company also provides continued support and replacement filters for additional BreatheSmart models such as the FLEX and selected earlier products.

Alen BreatheSmart 75i

BreatheSmart 75i is designed for larger rooms and open spaces. The current product range lists coverage of approximately 1,400 to 2,800 square feet depending on the air-cleaning interval used.

The 75i includes smart air-quality monitoring and app connectivity, allowing compatible users to monitor and control purifier functions through the mobile app.

Customers with large living rooms, open floor plans, master bedrooms, offices, and similar spaces can compare the 75i with smaller BreatheSmart models based on room size and desired features.

Alen BreatheSmart 45i

BreatheSmart 45i is a mid-sized True HEPA air purifier designed for bedrooms, offices, living areas, and other medium-sized spaces.

Current specifications list coverage of approximately 950 to 1,900 square feet depending on the air-cleaning interval. The purifier includes a Smart Sensor, automatic fan-speed adjustment, multiple speed settings, and mobile app compatibility.

The 45i also supports multiple replacement filter configurations, allowing customers to select a filter based on their preferred air-cleaning needs.

Alen BreatheSmart 35i

BreatheSmart 35i provides a more compact option for bedrooms, offices, apartments, studios, and other smaller spaces.

The current product range lists coverage of approximately 700 to 1,400 square feet depending on the air-cleaning interval. It also supports app control and smart air-quality monitoring.

Alen BreatheSmart 25i

BreatheSmart 25i is one of the smallest current BreatheSmart options and is designed for smaller indoor spaces.

The current product range lists coverage of approximately 400 to 800 square feet depending on the air-cleaning interval. Its smaller footprint makes it an option for bedrooms, home offices, dorm rooms, and similar spaces.

Alen BreatheSmart FLEX

BreatheSmart FLEX is a True HEPA purifier designed as a straightforward alternative for customers who do not require all of the connected features found on selected smart models.

The FLEX can clean air in spaces up to approximately 1,400 square feet once per hour on its highest setting. It offers four fan speeds and multiple compatible filter options.

Unlike several BreatheSmart smart models, the FLEX does not include an air-particle sensor or app control, making it important to compare features before choosing between models.

Alen True HEPA Filters

Replacement filters are an important part of the Alen ecosystem.

Depending on the purifier model, customers can choose from compatible True HEPA filter configurations designed around different indoor-air concerns, including general airborne particles, smoke, odors, and certain chemical pollutants.

Always select a replacement filter specifically listed as compatible with your purifier model.

Alen Filter Replacement

Filter life varies by purifier model, usage, indoor conditions, and fan settings.

Current guidance provides approximate replacement intervals of:

• BreatheSmart 25i: approximately 6–9 months
• BreatheSmart 35i: approximately 6–9 months
• BreatheSmart 45i: approximately 9–12 months
• BreatheSmart FLEX: approximately 9–12 months
• BreatheSmart 75i: approximately 12–15 months

Customers can also monitor the filter indicator on their purifier, while compatible smart models may provide additional filter information through the mobile app.

Alen Smart Sensor & Auto Mode

Selected Alen purifiers use a Smart Sensor to monitor airborne particle levels.

Compatible models can display current air-quality conditions using a color indicator and automatically adjust fan speed when Auto mode is enabled. Smart Sensor availability varies by purifier.

Alen Air App

Selected connected BreatheSmart models work with the Alen Air app for compatible iOS and Android devices.

App-enabled models allow users to access compatible purifier controls, monitor air-quality information, and review selected device information remotely. App support varies by model.

Air Purifiers for Different Room Sizes

Alen offers different BreatheSmart models so customers can match purifier capacity to the size of the intended room.

As a general comparison within the current lineup:

• 75i — designed for larger spaces
• 45i — designed for medium-sized rooms
• 35i — designed for smaller spaces
• 25i — designed for compact living spaces

Room layout, ceiling height, desired air-change frequency, and indoor conditions should also be considered when choosing a purifier.

Alen Filter Subscription

A replacement-filter subscription provides scheduled delivery of compatible filters and may include subscription savings.

Maintaining qualifying genuine replacement-filter purchases is also an important requirement for continued eligibility under the Alen Forever Guarantee. Customers should review the current guarantee requirements when registering their purifier.

Alen Forever Guarantee

Eligible air purifiers can qualify for the Alen Forever Guarantee when the applicable requirements are maintained.

To qualify under the current program, customers need to register the purifier's serial number and maintain an active qualifying filter subscription or provide qualifying proof of genuine replacement-filter purchases within the required period.

Coverage and replacement conditions change after the initial manufacturer-warranty period, and the guarantee is non-transferable. Customers should review the current Forever Guarantee terms for complete eligibility requirements and exclusions.

Alen 60-Day Return Promise

Products purchased directly from the official online store are currently backed by a 60-day Love It, or Return It promise.

Return eligibility and conditions can depend on the product and circumstances, so customers should review the current return instructions before sending an item back.
