Review

Design and build

Alen BreatheSmart 75i Review

The air intake vents are at the sides of the unit, allowing the airflow from bottom to top. The air filter is positioned behind the front panel allowing it to sit flat against the wall without blocking any airways.

With two wheels at the back and a hidden handle, I can quickly move the purifier around the room without lifting it. What I like most about the design are the nine customizable front panel options, which allow me to match my room interiors.

Air Purifying Performance

The Breathesmart 751 by Alen is made ideally for my 1300 sq ft room. The parameter that checks the number of times a purifier cleanses the room is called ACH or Air Changes per Hour. The ACH of this Alen model is 2. This means it purifies the air in my room two times an hour.

I noticed that this purifier could be a waste; I would need a smaller model that filters the air four to five times an hour. However, it works perfectly for large rooms.

The standard HEPA air filter eliminates about 99% of allergens in the air. In addition, the optional odor combined with a smoke filter removes toxins and other pollutants. The filter system is so fine that it can obliterate particles that are bigger than 1 micron, giving me more reasons to favor this purifier.

Filter system

Impure air leads to various underlying health issues, and Alen Breathesmart 75i caters to these problems specifically by offering an array of filters. Depending on the issues that vary from odor to allergies, you can choose the type of filters for your purifier. Every filter is a true HEPA, it is the other layers of the filter that acts against specific problems.

Filters Type

PURE – If your issues are allergies, dust, bacteria, pollen, germs, and mold, the PURE filter is the one for you. This type is the cheapest filter with two layers. This standard filter removes 99.97% of pollutant particles as it clears the air in the room. In case you don’t mention any specifications while purchasing, this type comes as a default filter.

FRESH – A more enhanced type is the FRESH 3-layer filter that will cost more than a PURE filter. It removes harmful chemicals and indoor gases like VOCs or Volatile organic compounds emitted from cooking, wall paints, varnish, and furniture polish with an activated carbon filter. If you are sensitive to VOCs, this filter is the one for you.

PET – As the name suggests, the PET filter is ideal for those who have pets at home. Without the activated carbon filter, this filter uses the patented molecular conversion powder to remove any strong pet odors by destroying them at a molecular level. This is an enhanced 3-layer carbon filter that works well to work against pet odor and dander.

HEAVY ODOR – Similar to the molecular conversion powder of PET filter, this type can remove heavy odors emitted from garbages, diapers, and other strong odors. When you have children playing in the house, you know they sweat, and this can emit an unpleasant smell, this filter can get rid of it with the goodness of true HEPA and anti-microbial filters.

Power Efficiency

When it comes to electrical appliances, my top concern is how much energy it consumes. With Alen Breathesmart 75i, even the highest setting will consume just about 45 watts of energy less than a light bulb. This is a great advantage because I can keep the purifier running for a long time without worrying about heavy power consumption. This model of Alen air purifier has multiple power-saving modes, which includes auto as well. It adjusts the output of the fan according to the air quality of the room. The Energy Star rating of this purifier ensures the efficiency of power consumption, which amounts to about $16 a year. The best part is the timer mode which makes it ideal for freshening the air after cooking.

Noise Level

Breathing healthy and clear air is excellent, but most of the time, it comes with the price in the form of an annoying sound that disturbs the peace. The low-speed fan of Alen Breathesmart 75i allows the purifier to emit a low noise at 25 decibels, which is almost as soft as a whisper. The highest speed of the fan also has a pleasant noise level which can be compared to that of a refrigerator.

The sound frequency of this purifier falls in the pink noise range. This is just one step below white noise, which we usually use to help us fall asleep. Pink noise is a continuous sound that encourages the sleep receptors in the brain. However, it does not help as much when I have extreme insomnia.

Pink noise is also as helpful as white noise to enhance sleep up to 25% and increase focus and productivity. This feature makes it perfect for my bedroom and my office as well.

Warranty

When you buy any appliance, a warranty is a great concern. With Alen Breathesmart air purifier, you get a lifetime limited warranty, this means any repairing and replacement will be free. Keep in mind that they won’t repair or replace for free unless it is caused due to faulty material or workmanship. This lifetime warranty is applicable as long as you operate the unit according to the instructions provided in the user manual.

Additional Features I Like

Child lock – When you press the ‘lock’ button, it will activate the child lock, and it will disable the function buttons unless you press the same button again. This is a great feature when I do not want the children to mess with the appliance while playing.

Ionizer – The ionizer adds negative ions in the air to trap those positively charged ions that carry bacteria and other allergens. This is an optional feature to activate an ozone-safe ionizer and improve the quality of air. The concept of this feature is like when the TV attracts dust on its screen.

Lights-off mode – When I want to cleanse the air while I sleep without being disturbed by the bright light from the purifier, this mode turns off the light.

Timer and LED indicator – The timer helps you to set the purifier in three settings while the LED indicator reminds you to replace the filter.

Instructions for Use

  • Remove the Alen Breathesmart 75i from its packaging in an upright direction, and pull on the front cover to release the magnets.
  • Pull out and down the filter to remove the packaging and place it back.
  • Push down from the top of the filter until you hear a click
  • Place back the front cover, starting from the bottom hooks and going upwards.
  • Find a grounded outlet and plug in the air purifier.
  • Push the power button to turn on and turn off the purifier
  • The colors around the power button indicate the air quality, blue being the lowest and purple indicating the highest level of airborne particles.
  • Turn on the ionizer to activate ozone-free and eliminate airborne particles.
  • The three lights in the filter indicators will remind you to replace the filter. When the light turns from green to yellow, it means it is time to order a new filter. When the indicator turns red, replace the filter.
  • Use the timer mode by pressing ‘timer’ between two, four, and twelve hours to run the purifier for a certain period without manually turning it off.

Maintenance

Keep your air purifier in optimum shape with minimum repairing, and the only way to do that is to maintain the unit regularly. It is no rocket science to take care of the device that gives you fresh air. Just follow the simple steps below and keep your purifier operating smoothly for years.

The filter has three indicators – green, yellow, and red. The green light will be on most of the time when you are using the purifier, and the yellow indicator will turn on shortly before it is time to replace your filter. The green light should be the right time to order a new filter because, by the time the indicator turns red, you will have to replace the filter. After replacing, push the ‘filter’ button and hold till it turns green again and you are good to go.

Do not clean or wash the filters as they are not designed to be reused. After using the purifier for some time, the filters get loaded with particles, and it loses its filtering power. Changing your air filter regularly will maintain clean air and avoid any compromise in the quality of air.

The black screen on the filter is the Pre-filter. It traps hair and other bigger particles, and it can be vacuumed periodically. For optimum performance, it is best if you replace your filters regularly, as it will extend the purifier’s life.

While cleaning the control panel, avoid using abrasive and harsh cleaning agents. Do not use scrub pads on the surface either. Wet a clean towel in soapy water and clean the panels and dry it with a soft fabric. Remember to unplug the purifier before cleaning and be careful not to let any liquid get inside the unit.

Both Alen Breathesmart 75i and Breathesmart 45i are excellent air purifiers. Here we will compare their features to see where they differ and what their similarities are.

Area coverage

Alen Breathesmart 45i

This model cleans the air in rooms that are up to 800 square feet. Any room that is around this size is ideal for this purifier to work efficiently.

Alen Breathesmart 75i

This model is larger and more potent that covers up to 1300 square feet. In 30 minutes, it will purify the air of a room as big as the listed coverage area.

Design

Alen Breathesmart 45i

This model is simple look-wise, but it is far from boring. You get an array of choices in its front designs to blend it into your home interiors. The structure is engineered to fit any space in your home without compromising the performance of the purifier.

Alen Breathesmart 75i

Although this model covers a larger area, the size of the unit fits perfectly well anywhere in the house. It also has several face designs to choose from to add beauty to your home.

The weight is heavier as it is more powerful. But when it comes to looks and design, both are similar.

Filtering Stages

Alen Breathesmart 45i

This has a three-stage air purifier that uses a HEPA filter for long-lasting performance. The air passes through a pre-filter which absorbs larger particles and then through the HEPA filter. The third stage is an ionizer that acts against dust, bacteria, and allergens without filters. The pre-filter is washable, so you don’t have to buy a replacement.

Alen Breathesmart 75i

This model uses three filters as well, the same as the 45i model. The only difference is the larger filters that allow more airflow speed because of their higher capacity.

Noise Level

Alen Breathesmart 45i

This model has four fan speeds, and at its highest, it can produce up to 55 decibels of sound frequency. The noise level is low enough to help you get better sleep at night with the lights-off mode.

Alen Breathesmart 75i

Just like 45i, this model too has a lights-off mode that you can turn on at night to sleep better. The sound frequency is lower in this unit, with a maximum of 49 decibels only.

Both these air purifiers have been engineered with almost similar features and performance levels. Alen 45i is ideal for smaller rooms, while 75i works best in larger rooms. In my opinion, there are hardly any differences and both win in their own ways.

Conclusions

The Alen Breathesmart 75i has a lot of cool features that are both practical and sleek. The price may be a drawback since it is on the higher side. However, the performance level and the results from consumer reports make it worth every penny.

Spending a lot of time at home, we inhale many pollutants that can harm our health. The Alen Breathesmart 75i offers a powerful cleaning system that eliminates almost all toxins, pathogens, and odors and gives us fresh, clean air.
