I’ve worked as an HVAC tech in Phoenix, AZ for the past 10 years. I created CoolAndPortable.com to help home owners select the right portable air conditioner, cooler or air purifier for their needs & budget in just a few minutes. For most of the time, it will switch between yellow and blue and occasionally to red when there is a spike in air pollutants.
The long-lasting filters for BreatheSmart 75i provide clean air protection on average for months. For usability, Alen BreatheSmart 45i is very easy to operate, with dedicated buttons on each function. You can cycle between the 4 fan speeds , reset the real-time filter replacement indicator, or use the 2, 4, 12 hours timer to shut down the air purifier after an interval. Auto mode automatically adjusts the fan speed based on the room air quality. FLEX air purifiers were designed for use in medium-sized rooms, such as bedrooms, offices or kitchens.
However, this did not affect the performance of the unit in any way. The BreatheSmart FIT50 is a premium air purifier with excellent performance. However, there are a few other units that are similar in size and price. You always know when the BreatheSmart FIT50 is working because you can see the light color on the unit from across the room. When there is dust and allergens in the air, you will see the unit detecting it and and responding.
Other optional filters (HEPA-Fresh, HEPA-Silver, and HEPA-Odorcell all feature a 3-stage system). For reference, 39 decibels is comparable to the sound of a library. Another thing to note about the BreatheSmart Flex is that it produces pink noise. Pink noise has a higher concentration of sounds at lower frequencies.
If you are looking for a dependable air purifier that can run continuously to clean the air in medium to large rooms, this is your product. Like all Alen purifiers, it comes with a limited lifetime warranty and excellent customer service. You won’t have to worry about buying a replacement product if you encounter manufacturer defects or if the purifier stops working even years into the future.
You can choose from 14 different panel covers which is a wonderful option for people who are looking for a purifier to blend in with their décor. It has no ionizer or any other electronic filtrations, certified by the California Air Resources Board. User feedback is strongly positive whether the purifier was bought to combat bad alen breathesmart odors or to help alleviate allergy symptoms, so it’s a good all-rounder too. As I said, these powerful devices are surprisingly quiet, even more since they both miss the Sleep Mode. On the other hand, Alen FLEX has a bit complicated pre-filter, since it is attached to the HEPA and a Carbon filter combo, therefore, not washable.
