Comparison: Alen BreatheSmart-Pure vs. Rabbit Air MinusA2 air purifier

The air quality in your home is something you should not take for granted. Irritants and indoor allergens have become common because of many pollutants.

Since modern homes are now airtight, air pollutants in homes cannot escape easily. Contaminants like fragrances, indoor dust, fire-retardants, formaldehyde, pet dander, and radon can reduce air quality in your house.

This means that you need to figure out a way of eliminating them. You can eliminate irritants and indoor allergens by using an air purifier.

If you have been shopping for one and came at a dilemma when choosing between Alen BreatheSmart and Rabbit Air purifiers, I’ve created this comparison to help you find out which is the best.

Choosing between two advanced air purifiers is not easy. First, both machines have a HEPA air filter that will trap and eliminate particles like pet dander, pollen, smoke, and dust mites from indoor air.

Second, the purifiers are well-tailored to personal styles and your home’s purification needs. But when it comes to Alen vs. Rabbit, which one should you buy? Here is a comparison of the two products.

I’ve compared these two air purifiers to find out which outperforms the other or offers real value for money.  Here are my findings:

Filtration efficiency

Modern air purifiers go through a series of filtration stages. These stages help to eliminate gaseous contaminants, odors, and particulates from the air. Most of these units have four stages of filtration and others have more.

How an air purifier filters indoor air will determine whether it will eliminate such things as dust, mold, germs, smoke, harsh odors, fumes, and pet odors from your house.

Also, more filtration stages help to prolong the optimal efficiency of a filter.

Alen BreatheSmart filters : Alen BreatheSmart and Rabbit Air

Alen BreatheSmart-Pure air purifier has four unique HEPA Type filters. That means the unit has four stages of air filtration.

The four filtration stages in Alen BreatheSmart filters are enough to eliminate 99% of particles greater than 0.3 microns from the air.

Rabbit Air MinusA2

Rabbit Air MinusA2 has six stages of air filtration. The Rabbit Air filter will purify and deodorize the air at the same time. It uses a BioGS HEPA filter which traps and eliminates common allergens from your house.

Throughout the six stages, the machine will trap allergens and particles as small as 0.3 microns at an efficiency of 99.97%.

Verdict: Rabbit Air MinusA2 is more efficient at removing pollutants from the air than the Alen BreatheSmart-Pure air filter. While both have HEPA filters that can eliminate 99% of particles as small as 0.3 microns, Rabbit Air has two more filters. These extra filters can remove more microorganisms from the air.

Room coverage

Room coverage is essential because air purifiers that rely on HEPA filters only clean nearby air. That means the rest of the house is left unpurified.

An air purifier should cover a vast area to drag the whole room into the unit and clean the air.

Alen BreatheSmart-Pure

The Alen BreatheSmart-Pure air purifier is perfect for family rooms and open-concept spaces. It has broad coverage of up to 1,100 square feet.

Rabbit Air MinusA2

The Rabbit purifier only covers 700 square feet. If you have a more extensive room than this, you will have to move the purifier around.

But in general, the machine is perfect for small rooms.

Verdict: Choose the Alen BreatheSmart-Pure air purifier if you want to purify both large and small rooms.

Noise output

Electric air cleaners and HEPA-based air filters use a motor. The motor helps to draw air through their filters to purify it.

Unfortunately, their motors or fans can be loud during their operations. You need an air purifier that will work all-day and all-night without making a loud noise.

Alen BreatheSmart-Pure

Alen BreathSmart cross section

The Alen BreatheSmart-Pure air purifier comes with four fan speed options. Each option has its noise level with the lowest equating to a whisper.

Depending on your fan speed settings, the machine will emit sounds of between 41.5 and 56 decibels.

Rabbit Air MinusA2

The Rabbit Air MinusA2 air purifier comes with a BLDC motor that operates in five fan speeds.

Depending on your settings, the machine will emit sounds of between 20.8 and 45.6 decibels.

Verdict: If you are looking for a quieter air purifier between the two, consider the Rabbit Air MinusA2 ultra quiet HEPA air purifier. At the highest fan speed setting, the machine will emit a sound similar to a humming refrigerator.

Size and Portability

It is an excellent idea to have an air purifier you can easily move from one room to the other. That means check the machine’s weight and dimensions to determine its portability.

Alen BreatheSmart-Pure

Alen BreatheSmart-Pure air purifier measures 10 x 17.8 x 26.8 inches and weighs 21 pounds. The dimensions and weight of the machine mean you can move it from room to room.

It will also fit seamlessly into almost any space in your house as it does in mine.

Rabbit Air MinusA2

Rabbit Air MinusA2 air purifier measures 24 x 22.8 x 9.8 inches and weighs 23.9 pounds.

With such measurements, you can carry it around to purify any room in your house.

Verdict: When it comes to size and portability, the Alen BreatheSmart-Pure is lighter than the Rabbit Air MinusA2. One noticeable difference is wall mounting. If you want an air purifier you can carry around and mount on any wall; the Rabbit Air MinusA2 purifier is what you should consider.


Today’s air purifiers have at least a one-year warranty. Anything less than one year or no warranty should raise a red flag.

Having a warranty means the company is reinforcing its commitment to service and quality.

Alen BreatheSmart-Pure

Rabbit Air MinusA2

The Rabbit Air MinusA2 air purifier comes with a 5-year warranty.

Verdict: When it comes to warranty, Alen BreatheSmart air purifier beats Rabbit Air MinusA2 air purifier. That means you can use it to ensure years of pure air in your home.

The choice of the Alen BreatheSmart vs. Rabbit Air purifier is not easy. Both machines are powerful enough to eliminate 99.97% of pollutants from the air. If you want to buy either machine, consider how each machine filters the air.

Also, determine the energy efficiency of the machine to know which one will save your power bills. But what air purifier is a step up from Rabbit Air? Essentially, the only machine that can outperform Rabbit Air in some aspects is the Alen BreatheSmart air purifier.
