Design and Size

Alen FLEX

Experience a new level of air purification with the Alen BreatheSmart FLEX. The mid-size device has an undeniably luxurious look and feels, made from a robust plastic that boasts superior build quality when compared to similar models in its class.

Plus, generous dimensions make room for a more powerful motor and larger filter – so you know your home or office space is receiving truly thorough cleaning capabilities whenever it’s on!

Alen FLEX is a marvel of modern design, crafted with eye-catching aesthetics and impressive build quality. Its 78 cm power cord cable adds to its convenience while the choice of 6 color options caters to all types of preferences – whether you prefer espresso or brushed stainless, graphite or oak, weathered grey or white. I personally went for the subtle yet chic look that only Alen Flex’s “white” shade can provide!

Control Panel

At the top is Alen’s control panel, adorned with 5 touch keys and its graceful logo. The power button – the largest of all five – occupies center stage here; it is arguably the most essential key on this board as pressing it kickstarts your device.

Not only that, but the second press of this button dims all LED indicators- a useful feature for those who plan to use the device in their bedroom. When powered on, you will notice a bright blue light surrounding the power button.

Located on the far left is the filter button, labeled with a sign displaying how much use it has seen. Just next to that is a timer button exhibiting its own gauge of performance.

Furthermore, the speed button allows you to quickly toggle between four different speeds.

Lastly, there’s the lock button which ensures all other buttons won’t be activated or switched off unintentionally.

Features

Alen FLEX is a powerful air purifier that aims to bring simplicity and convenience into your home. Though it lacks certain advanced features, such as auto mode or smart sensors found in pricier models, what you do have here are reliable quality and dependable performance – making the Alen FLEX an unbeatable value for its category.

Switching off the indicator on the device

Alen FLEX provides a simple way to turn off the device’s indicator lights: simply press the power button when the air purifier is on. This will deactivate all indicators and switch off your Alen FLEX for good. Each time you need to use it again, just repeat this process and enjoy fresh, clean air!

Timer

A timer is an invaluable tool, especially for Alen since it’s the only option to “program” its operating mode. Without a timer, Alen would be out of luck. With the timer activated, the Alen FLEX will automatically shut off after a preset period of two hours, four hours, or twelve hours.

Filter Reset Indicator

With the innovative filter reset indicator on FLEX, you’ll never have to worry about when it’s time to swap out your air purifier filters again. You won’t need an external reminder or calendar because this device will let you know exactly when a new filter is needed!

A trio of round indicators should appear above the “Filter” button, with only one indicator illuminated green when you first begin using the device. As soon as a yellow signal appears, it is time to consider changing your filter in preparation for replacement; once red indicates its presence, immediate action must be taken and the filter altered on your apparatus.

Control Panel Lock

If you have kids around the house, this is the ideal way to secure your device against accidental commands. This feature can keep toddlers from mistakenly shutting down or changing modes on your gadget.

Keep your finger pressed firmly on the lock button for a full 5 seconds to activate it. After that, no other buttons will be registered unless you start the process over again.

Filters

Alen BreatheSmart FLEX offers you the choice of three different filters, all with a fundamental True HEPA filter. The greatest variation between each one is in the activated carbon filter contained within them.

The optional filters are:

  • Dust, Mold, Pet Odors
  • Dust, Mold, Pet Odors + Smoke
  • Dust, Mold, Pet Odors + Heavy Smoke

After testing the device with its “Dust, mold, pet odors + smoke” filter installed, I was astounded by how effectively and efficiently it performed. It proved to be a truly optimal choice for my needs.

Pre-filter

The pre-filter acts as the preliminary stage of filtration, safeguarding your True HEPA filter with a snug Velcro strap. It prevents larger particles such as pet fur and dander from penetrating the HEPA filter, substantially enhancing its useful life! Furthermore, you can easily detach it if necessary.

True HEPA Filter

True HEPA is the principal and most efficient level of filtration to purify the air. The BreathSmart FLEX utilizes a medical-grade H13 True HEPA layer that eliminates 99.99% bacteria, aerosolized viruses, and airborne particles larger than 0.1 microns from your environment!

Not only does this filter remove such matter but it also lasts 3-5 months longer than standard filters – making it the perfect investment for clean air in your home or office space!

Activated Carbon Filter

The final stage of filtration is the activated carbon filter. It’s this step that ensures gases, VOCs, and other foul smells are eliminated from the air – leaving your home smelling fresh!

Trust me, go with the carbon filter option to get full advantage of the Alen FLEX. This way, you’ll be well-equipped for any surprise scenarios.

Performance

The Alen BreatheSmart FLEX is the ideal air purifier for those in search of fresher, healthier living spaces. It can effectively tackle dust, mold spores, and much more from any room up to 300 square feet.

560 sq. ft. Room Test

Measuring 560 sq. ft, the first examination was conducted in a room slightly undersized compared to our suggested dimensions; however, I still proceeded with placing an Alen BreatheSmart FLEX and running it fully open.

In only one hour of operation, the FLEX drastically decreased air pollution by 94%, transitioning an AQI of 126 to 8. This is a remarkable result considering that the room in question was slightly smaller than what’s recommended.

Speed 3 48.9 dBA
