Alen BreatheSmart 75i
Quick Summary:
The overall quality and performance of this unit are remarkable. The ease of use is super simple. Just take it out of the box, remove the wrappings, plugin, and turn on. The size of the unit is on the larger size but is easily portable. Air cleaning ability is superior. Only 1 filter to replace every year.
After using the Alen BreatheSmart 75i Air Purifier for the last 2 weeks, I am concluding that this is among the best air filters on the market today and is the most advanced of all Alen air purifier models. See my full review below to find out why I came to this conclusion.
- B7 PURE FILTER: Alen’s Pure HEPA filter helps remove airborne allergens, dust, pollen, dust mites, dander, pet hair, mold, and more. The True HEPA filter traps potentially harmful airborne particles as tiny as 0.1 micron. This office and home air purifier can purify up to 1,300 SqFt every 30 minutes.
- WIDER COVERAGE, QUIET AIR PURIFIER: Designed for extra-large rooms, the 75i is the ideal air purifier for large rooms and open-concept spaces such as living rooms and kitchens. It can purify up to 1300 SqFt every half hour while generating whisper-soft volume at the lowest setting for a quiet operation.
This air purifier uses pure HEPA air purifier filters that are over 99% efficient, meaning that they can capture particles in that size range (.1 micron and larger)
Thanks to the Tuya smart app, you can now download the app and pair this air purifier to your mobile device and control or check air quality remotely.

Filter light indicator
It is also equipped with a filter-led light indicator, so you won’t have a hard time guessing when your filter is due for a change. The filter indicator is based on the time the air purifier has been on and the fan’s speed. It will turn from green to orange to alert you about changing the filter and orange to red when you need to change the filter.
BreathSmart 75i Setup
First-time setup is pretty easy; everything can be set up in under 5 minutes. It does not come with remote control, but the control panel is touch and easy to operate. Besides the sleek control panel, you can use the app to monitor and control the air purifier from anywhere. Now that is way better than a remote control.
Removing the filter is easy and comes off with just a snap off the front cover, which is magnetic.
A pre-filter before the primary filter catches larger particles before they can find their way into the primary true HEPA filter. You can vacuum the prefilter from time to time, but the main filter has a long life of about 12-18 months.
It has four fan settings and 4 led lights to indicate the air quality at a particular time, with blue being the cleanest and purple indicating the worst air quality. Here is a quick overview of what each LED color on the 75i unit represents:
Levels of airborne particles (PM2.5)
| Blue | Excellent | 0-3 |
| Green | Good | 4-8 |
| Orange | Fair | 9-20 |
| Red | Poor | 21-35 |
| Purple | Very poor | 36+ |
This purifier has a built-in ionizer, but it does not create ozone.
Best Placement Of the 75i
The unit itself is not too big and won’t take up much space in a room.
In terms of where to place your purifier, Allen recommends placing it along the longest walls of the room. There is no need to leave space between the back of the purifier and the wall at the back so you can safely position your purifier against the wall. This is because the air intake is in the sides of the unit, and the purified air comes from the top behind the display panel.
BreatheSmart 75i Filtration process
This purifier has an H13 True HEPA filter and a carbon filter. The combination of the different filters helps clean the air & remove unwanted pollutants, such as those below:
- Allergens
- Bacteria
- Chemical fumes (vocs)
- Dander
- Dust
- Mold
- Odor
- dust
- Pet fur.
- Smoke odors
This model has an exceptionally high performance, independently verified by AHAM (Association of Home Appliance Manufacturers). Not all filters are independently verified, so with this in mind, you are assured that you are getting the quality as is marketed. It has an AHAM stamp of approval.
The air filters can last anywhere from 12 to 18 months, making them cheaper than any other air filters on the market in the long run.
CADR Rating of the 75i
CADR (clean air delivery rate for the 75 it is 347, this is higher than any similar air purifier on the market.
Noise levels of the 75i
When it comes to noise levels, everyone wants to have the quietest air purifier, which is exactly what the 75i provides.
The unit is relatively quiet, actually quieter than any other similar air purifier on the market. Even on the Turbo setting, the sound levels are around 49 decibels, so you won’t be able to hear it when the tv is switched on.
You can’t even hear it running unless you are 2 feet away. Below are the sound levels on each fan setting.
Speed 1: 25 dB;
Speed 2: 33 dB;
Speed 3: 39 dB;
Speed 4: 44 dB;
Turbo:49 dB.
Portability
Although this air purifier is large compared to other Allen air purifiers, it is very portable. It can easily be moved from one room to another as it comes with wheels.
The wheels move great, but this might not work well on some hard wooden floors. In that case, you may have to carry it from one point to another.
That said, a back handle on the unit helps to balance the unit when moving it.
Good night sleep
For those that are bothered by led lights and can’t sleep through, there is a provision for turning off the led lights while it’s still running.
Coverage Area of the 75i
Besides its exceptionally quiet operation, the maximum rated coverage area is around 1300 sq. feet. So basically, it will take about 30 minutes to clean up the air in that size of the room. However, that does not mean it can’t clean up the air in a room that is larger than it. That simply means it still takes double the time to clean up the air in a 2600 square feet room.
Smart sensor
The smart sensors on these air purifiers detect dust and other pollutants in the air. When there are pollutants in the air, the air purifier kicks into action automatically, speeding up or slowing down fans to improve air quality.
You might notice that for the first few minutes of running it, it’s going to be running on high (especially if it’s the first time you are running it), but after the air quality stabilizes, it’s going to be running a little bit lower.
The auto mode has to be on for the fan to adjust the speed depending on changes in the surrounding air quality. For example, when you start cooking. The fan will speed up to try and kill the cooking smell.
So, turn on auto mode and enjoy allergy-free air in your home, which is unbelievably awesome.
Power consumption of the 75i
When it comes to electricity usage, it is energy efficient and star certified. Using this unit all the time throughout the day on the highest speed setting will only cost you $.13 per day
Here is a breakdown of energy use by this unit:
$.02 per day on speed 1 and $.13 per day on Turbo.
And if you were to run your 75i on speed 3 24/7, it would cost about $26 per year, but that is unrealistic, considering that you won’t have to run the unit on turbo 24/7. So, running the unit should cost you less than that annually, say, $15.
Not only will this unit improve the quality of the air you breathe, but it will also significantly reduce dusting on surfaces of your home.
Lifetime warranty
The warrant is indefinite, meaning your unit will be covered throughout its lifetime. And that includes troubleshooting, repairs, and even replacement of your air purifier.
The lifetime warranty assures you of every penny you spend on this unit. But take note that this warranty does not include customers based in Canada.
