During the winter months, we start spending more time indoors, but this can significantly affect the quality of the air inside your home. With closed windows and heating systems running, it’s easy for dust, allergens, and moisture to build up, all of which are major contributors to indoor air pollution. Over time, poor air quality indoors can seriously affect your health, leading to irritation in your skin and eyes, as well as allergies, and could even cause respiratory issues. One reliable way to improve the air quality inside your home is by investing in an air purifier. These devices utilize high-end filters to remove airborne pollutants from the air indoors, making it safe to breathe. If you’re looking for an air purifier that can effectively filter the air inside your home, the Alen BreatheSmart 35i is a great option.
The Alen BreatheSmart 35i is a smart true HEPA air purifier that’s equipped with a medical-grade H13 HEPA filter, which makes it capable of efficiently capturing 99.99% of airborne particles as small as 0.1 microns, including dust, allergens, mold spores, and germs, while also absorbing other airborne pollutants such as smoke and VOCS. It also integrates a built-in Air Quality Index (AQI) sensor that enables it to monitor PM2.5, VOCs, CO2, temperature, and humidity in the air. This air purifier is rated to have a 1,000 sq. ft. coverage area, making it suitable for small- and medium-sized living spaces, and also has a whisper-quiet operation. It also features a filter change indicator light, a child lock button, 3 light levels for dimming its interface, an air quality indicator light, 4 fan speed settings, and an Auto Mode that automatically adjusts its fan speed for optimal performance, and boasts Bluetooth and Wi-Fi connectivity. Via the Alen Air App, you can control its operation, track current air quality, configure scheduling, and receive air quality alerts and filter status updates.
Engineered to deliver powerful air purification and bring cleaner air to small- and medium-sized rooms, this smart true HEPA air purifier enhances your indoor air quality, providing peace of mind for homeowners.
Here’s our full review of the Alen BreatheSmart 35i, where we talk more about all the features this advanced air purifier has to offer you.
DESIGN & SPECS
Starting with the unit’s size, this air purifier has a noticeably small footprint, measuring just 13 inches long by 7.6 inches wide by 20.6 inches tall (33.02 x 19.30 x 52.32 cm), delivering powerful air purification without taking up too much space. The device weighs approximately 13 lbs. (5.89 kg).
The Alen BreatheSmart 35i also sports a stylish and modern design, which gives it a very discreet look, allowing it to easily blend in within your living space. Its body comes in a solid White color and has a Black accent all the way around it.
Moreover, the device also packs a premium and sturdy construction.
Moving on to the air purifier’s internal components. For filtering the air indoors, the Alen BreatheSmart 35i utilizes a medical-grade H13 HEPA filter, which makes it capable of efficiently capturing 99.99% of airborne contaminants as small as 0.1 microns, including dust, pet dander, mold spores (like Aspergillus Niger), and other allergens, as well as germs, including bacteria (like Staphylococcus Aureus) and aerosolized viruses (like MS-2 Bacteriophage), all without emitting ozone.
It’s important to note that the company (Alen) offers its customers two different options for the air purifier’s filter, which include the “Pure” filter (good for capturing dust, allergens, and mold) and the “Fresh” filter (which can also absorb cooking odors, smoke, VOCS, and other harmful chemicals in the air).
The main difference between these two filters is that its Fresh HEPA filter is also integrated with an internal layer of over 2 lbs. of activated carbon pellets, which also makes the air purifier capable of absorbing smoke and VOCS. Unlike standard HEPA filters that have limitations in addressing odors and harmful gasses indoors, the activated carbon pellets in the BreatheSmart 35i’s H13 HEPA filter have microscopic fractures that act as a sponge, effectively absorbing bad bad and harmful gasses.
When it comes to the maintenance required for the air purifier’s filter, know that both its Pure and Fresh filters are designed to be fully replaceable. The BreatheSmart 35i’s Pure filter (sold separately at $54) is rated to have a lifespan averaging between 9 to 12 months, while its Fresh filter (sold separately at $64) has a slightly estimated lifespan of 6 to 8 months.
In addition to its medical-grade H13 HEPA filter, this smart air purifier also comes equipped with a built-in Air Quality Index (AQI) sensor that’s powered by Alen’s proprietary airID AI-driven particle identification technology (a type of light imaging technology for monitoring harmful airborne particulates), making it capable of detecting and measuring PM2.5, VOCs, CO2, temperature, and humidity in the air.
Its AQI sensor also enables the air purifier to automatically adjust its fan speed according to the estimated air quality indoors (which will depend on what’s detected in the air).
As for the air purifier’s total coverage area, know that the Alen BreatheSmart 35i is rated to have a 1,000 sq. ft. (92.90 m²) coverage area with a CADR (Clean Air Delivery Rate) of up to 190 CFM (cubic feet p/ min) / 322.8 m³/h, making it particularly suitable for filtering and purifying the air in small- and medium-sized living spaces like bedrooms, studio apartments, and home offices.
Lastly, this air purifier also boasts a whisper-quiet operation that varies between 29 dB (lowest fan speed) to 42 dB (highest fan speed).
The air purifier’s air intake is located at both sides as well as the base of the unit, while its air outlet is integrated at the top-center of the device, through which clean air is released from in an upwards direction.
The device has a rated Power Consumption of 0.9 to 40 Watts (24V AC / 60 Hz). Its power consumption depends on what fan speed setting you have the air purifier set it to work at (whether that’s done manually or automatically by the device’s AQI sensor).
INTERFACE / CONTROL PANEL
For controlling its operation, the Alen BreatheSmart 35i comes equipped with an illuminated touchscreen control panel that has an intuitive interface.
At the left-hand side, there’s a filter change indicator light, followed by a child lock button, and then a Light button featuring 3 light levels for dimming its control panel.
Integrated above its Light button, there’s also a smart light sensor that automatically detects daytime and nighttime, automatically adjusting the light level of its control panel.
At the center of its control panel, we have the air purifier’s Power On/Off button, along with a Color Ring air quality light that indicates the current air quality in the room.
At the right-hand side, we have a Speed button for adjusting the air purifier’s fan speed with four (x4) fan speed settings to choose from (Low at 66 CFM, Medium at 98 CFM, High at 135 CFM, and Turbo at 190 CFM), followed by an Auto Mode button for enabling its Auto Mode, which automatically adjusts its fan speed, depending on the amount of harmful airborne particulates its AQI sensor detects in the air indoors.
When working in Auto Mode, the built-in lights from the air purifier’s control panel are automatically turned off.
Finally, there’s also a Bluetooth indicator light that informs users when the device has been paired successfully with their smartphone.
CONNECTIVITY
For establishing a wireless connection with its mobile app, this smart air purifier utilizes both Bluetooth and Wi-Fi connectivity.
THE SMARTPHONE COMPANION APP – The Alen Air App
