Alen BreatheSmart 75i vs. 45i – The Ultimate Showdown
We already see that both models differ in terms of coverage area. The 75i is suitable for large rooms, and the 45i is better for small spaces. But is it the only difference?
In this section, we will compare and review the top features of both models.
Alen BreatheSmart Design & Size
In terms of design, there is no difference between the two because they both belong to the same series by the company. However, there is a significant difference in the size of these air cleaners.
The 75i is a much bigger air purifier; its dimensions are 27-inch x 18.5-inch x 11.5-inch, and its weight is 27 lbs. On the other hand, the 45i’s dimensions are 25-inch x 15-inch x 8.5-inch, and it only weighs 15 lbs.
The 75i is much bigger and has almost doubled its capacity compared to the 45i. In addition, the 75i is designed for larger rooms that measure to be 1300 square feet. In comparison, the 45i is suitable for 800 square feet of space. So the 75i has a definite edge over the 45i regarding design and size.
Both air purifiers look simple, but that doesn’t mean Alen is boring. There are plenty of face designs available. You can pick the right one based on your interior.
Alen BreatheSmart Portability
This one is a brainer. The 45i model is much smaller and easier to move from one place to another. In addition, it only weighs 15 lbs, while the 75i weighs 27 lbs. So, the 45i is much more portable than the 75i because of its small size and easy handling.
If portability is your top priority, you must go for the 45i. It’s pretty tiny, and you can move it around. But the same can’t be said for the 75i model. This powerhouse is designed to take on a wide coverage area without impairing its performance.
Alen BreatheSmart Purifying Power
There will be a tie here because both machines come with a long-lasting True HEPA or H13 filter. This medical-grade filter can capture up to 99.99% of germs with all particles over 0.1 microns. Both devices can do this, so you are not missing out on anything here.
However, the primary difference lies in the operating cycle. The 45i can run for about 4 to 6 minutes of cycle per hour.
In contrast, the 75i goes 6 to 7 times per hour. It means that the 75i is much more capable of providing clean air.
Alen BreatheSmart Key Features
The 75i is a much better option if you are looking for power and CFM. This is because it has a turbo speed that can easily reach 350 CFM. The 45i doesn’t come with any of such turbo modes.
But these air cleaners can extract up to 99.99% of germs that are all 0.1 macros or above. In addition, the intelligent sensors on both these units will allow you to see the current air quality status with the color LEDs.
There are three different cleaning stages in the 45i. First, the air passes through a pre-filter, then it passes through the HEPA filter and comes to the ionizer that removes any bacteria for germs.
The 75i also works in the same manner. The only difference here is that the latter has much bigger filters.
Alen BreatheSmart Noise Level
There are five different speeds and an automatic speed adjuster. On the other hand, the 45i comes with a top rate of 215 CFM, so it’s pretty mild. Due to this, the 45i also comes with a slightly lower noise level rating at low speed. However, both air cleaners produce similar noise at high speeds.
In most cases, both these machines are quiet and don’t make much noise. You might not notice a unit running around you unless you turn its turbojet on-air and run it at full CFM. It means you can nap while your air purifier is working and don’t bother the boat waking up from the noise.
The 45i comes with a noise level rating of 23 dB at low speed and 49 dB at high speed. On the other hand, the 75i comes with a slightly high noise level rating of 25 dB, but the high-speed noise level is similar to the high speed if you compare it with 45i.
Both air purifiers are generally quite soft in their operation. For reference, human conversation comes with a noise level of 60 dB. It means that these cleaners are pretty low and barely noticeable when running.
Alen BreatheSmart Power Consumption
The 75i comes with a power supply 120AV and has a 7 feet long power cord attached to a 3-prong power plug. This power consumption is 1.8W to 45W. On the other hand, the 45I also comes with a 120AV power supply and a 2-prong power plug attached to a 7 feet long cord. The power consumption of this smaller cleaner is 1.1W to 50W.
The bigger machine is going to be much more power-hungry as well. But you don’t have to worry much about this factor because both are Energy Star rated, so your wattage will be kept low.
Alen BreatheSmart CADR, ACH, Room Coverage
The 75i comes with a CADR rating of 347, while that of the 45i is only 245. Regarding air changes per hour or ACH, the 45i does around 4 to 6 times per hour based on the weather and requirements.
But the 75i does that even better, and it can change the air around 6 to 7 times. In addition, the 75i comes with an area coverage of 1300 square feet, while the 45i comes with 800 square feet.
Alen BreatheSmart Maintenance and Usage
There is not much difference between these two models, and they are almost identical. As far as the file is concerned, it will last for at least 12 hours if you use your air purifier daily for 24 hours.
In addition, they both come with automatic sensors designed to handle the air quality independently and different colors indicating different air qualities.
One of the most significant advantages of going for Alen is that you don’t have to go through maintenance. And the best part is that you can use it in every room and it will become part of the interior of that room.
