Alen BreatheSmart Classic vs. 75i HEPA Air Purifier Comparison

With so many of us suffering from allergies and reactions to pollutants, it makes sense to use a quality air filtering system to remove dust, pollen, mold spores and other pollutants, as well as unpleasant smells, from the air we breathe.

Alen BreatheSmart Classic vs. 75i HEPA Air Purifier

Classic

Design and Size

The Alen BreatheSmart Classic and 75i HEPA air purifiers come in 14 colors to be as non-obtrusive as possible in your living or working space. Both run quietly, especially in the lowest operating mode at 41 decibels up to only 49 dB for the 751 and 56 dB for the Classic at the turbo speed mode. With the “lights-off” mode, their quiet operation means they can run in your bedroom whilst you are sleeping.

The 75i is approximately 1.5 inches bigger all round and 6lbs heavier than the classic, but it also can handle 1,300 square feet against the Classic’s 1,100 square feet. It should be noted that measurements for air purification coverage are based on a room with closed doors and windows. If you have, for example, an open staircase, the cleaning will be less efficient.

Both machines have a carrying handle so they can be moved from room to room.

The easy to read displays show you immediately how bad the pollution is in your air. Blue shows you a low level, yellow a higher level, and red suggests potentially dangerous air quality levels.

Warranty

One of the truly unusual features of the Alen BreatheSmart range is a lifetime warranty on the machine itself. As these are not cheap machines, this does offer extra customer confidence. It also shows that the company has faith in its products.

The Filters

The HEPA (High-Efficiency Particulate Air) filter system offers different choices depending on your individual needs. There are four types of filters available, so you can choose the best one to fit your needs. The standard is the Pure filter which is ideal for general dust and allergen cleaning; the Silver is for mold spores, germs and especially good for asthma sufferers; the Freshplus cleans smoke from cigarettes and open fires and the Odorcell is perfect for getting rid of those smelly nappy and pet odors as well as cigarette smells.

Each machine has a pre-filter which can be washed and put back into the machine, usually every 2 to 3 months, depending on usage and pollution levels. This prevents having to replace the HEPA filters too frequently. The light on the display will indicate when it is time to replace the main filters, which typically last ten months.

Another advantage of the BreatheSmart range is the option of turning the Ionizer on or off. The Ionizer charges the pollutant particles and helps the filter remove them better. It also helps the room smell fresher. But some questions have been raised about the safety of Ionizers so the optional feature suits everyone.

Efficiency

When in automatic mode, the sensors in both machines raise and lower power in reaction to the pollutants in the air, thereby saving energy as well as wear and tear on the machine itself. (Alternatively, you can choose a fixed setting.) The 75i is even more energy efficient using only 45 watts at the highest speed versus 105 watts for the Classic.

The 75i cleans 99.7% of particles over 0.3 microns whereas the Classic is a close runner up with 99% cleaning of the same.

The 75i also cleans more quickly than the Alen Classic, removing 99.97% off all pollutants in a 1,300 square foot area in only 30 minutes whereas the Classic takes 2 hours to clean its smaller 1,100 square foot area.

Conclusion

Firstly, measure the area you want to purify. There is no point paying approximately 25% more for a bigger model if you don’t need that much coverage. However, the dramatically higher energy efficiency levels of the 75i might convince you if it’s a close call as to which size you need. The 75i is larger but quieter at high speeds so is space more important than noise levels for you?

The quicker speed of the Alen 75i might be vital for chronic allergy sufferers as well might the extra 0.97% cleaning it provides.

The choice of the type of filter is crucial and you should make a checklist of why you decided to buy a purification system in the first place and choose the filter accordingly.

Both these machines are high quality, efficient removers of harmful substances in your home and choosing the right one will certainly let you live healthier and happier lives.

If you have a large space you want to remove irritants from, We recommend the Airmega 400. All of Coway air purifiers do an excellent job of attacking indoor pollutants, and we highly recommend any of them.
The Levoit Vista 200 air purifier has some strong suits, but in our opinion it falls short of carving out a meaningful niche for itself. Its ideal use would be in a small bedroom occupied by someone who is sensitive to noise.
With high end air cleaning performance, the Honeywell HPA300 is the perfect combination of power and finesse. It cleared airborne particulates out of a smokey testing room faster than most air purifiers.
