What is a HEPA Air Purifier?

An Air purifier system is a device that assists in the removal of contaminated air from our residents. It improves indoor air quality by cleaning air pollutants such as dust, pollen, fur, and smoke.

Some of the benefits of using an air purifier include reduction of fatigue since fresh air boosts your energy levels, an increase in blood circulation, and making your immune guards stronger and fierce towards external invasion.

For the ultimate indoor air quality, therefore, you need to use a HEPA air purifier. HEPA is an acronym for "High-Efficiency Particulate Air" or "High-Efficiency Particulate Arrestance."

 An air purifier with HEPA filters is better than one with tradition filters. This is because it improves air quality without running up your electricity bill.

Furthermore, unlike the traditional purifiers, the Best HEPA Air Purifier for Dog Allergy is highly efficient at capturing microscopic particle, including  pet dander and mold.

Therefore, no need to worry when your pet makes a mess or you make diaper change to your little one. The HEPA-OdorCell is your all-around home odor solution.

When it comes to smarts, we are further intrigued by intuitive intelligence that detects airborne particles with the aid of highly efficient Laser Smart Sensor.

2. Rabbit Air BioGS 2.0 (Editor's Pick)

If you`re looking for an exceptionally super quiet air filter for a small room, the Rabbit Ultra Quiet SPA is the ideal choice.

Rather than using the traditional brushed motors, the secret to the quiet operation lies in the Brushless Direct Current Motor Blade which is more efficient and quieter.

What`s more, the blades can operate at five varying speeds, with the lowest speed having virtually no sound.

A major highlight which is vital for individuals with (dog) allergy is the BioGS HEPA filter. The HEPA filter is highly efficient at trapping microscopic air particles down to 0.3 microns in size like dog dander, dust, and smoke particles.

The optimum filter efficiency is not only essential for reducing allergies but also supporting a prolonged filter life.

Speaking of prolonged life, the Rabbit Air is economical at the very least. For a start, the Charcoal-based filters last up to 3 years, based on 12 hours daily use. While the pre-filter, which traps the large particles, lint, and hair, is permanent and washable.

Like the Alen Classic air purifier, the Rabbit SPA-550A has odor correction function. But rather than using proprietary technology, it makes use of the time-tested activated charcoal carbon filters to reduce odors and VOCs.

Alongside the odor-function is a negative ion generator, which is handy in fortifying and freshening your indoor air.

  • Has Longer filter life

The filter traps all the allergy-causing matter ranging from dander, dust, smoke, and any airborne materials, meaning that dog allergies are a thing of the past with the Honeywell.

Though the pre-filter is not permanent or washable as in the case of the Rabbit Air, it has a modest lifeline of 3 months. The HEPA filter on the other hand, which traps the microscopic details has a generous life of one (1) year before replacement.

Again, the filters are designed in a friendly manner made with the DIYers in mind, and no tools are required to change the filters.

The carbon filters fitted on the Rabbit Air are necessary for eliminating VOCs/Gases/Odors.

What is a HEPA Air Purifier?

A HEPA Certified filter must pass the test of capturing 99.97% of 0.3-micron particle in size. It must filter a particle of  0.000012-inches in diameter and 300 times smaller than the human hair. It also means the size is 25 to 50 times smaller than what your eye can see.

Factors To Consider When Buying HEPA Air Purifier

When buying the best HEPA Air purifier, you need to consider some factors that include:

Your Personal Needs

There are a plethora of air filters in the market, and every filter serves a specific purpose.

Therefore, before purchasing a filter, you should first consider your specific needs.

For instance, if you have a pet, and you are looking to manage pet dander, you should purchase an air purifier with a HEPA filter.


HEPA filters offer an extra layer of capturing the microscopic and molecular particles, which would otherwise not get trapped in a regular filter.

The Floor Area of your House

Next in line is to consider the size of your house.

When it comes to floor area, the size of purifier matters a lot. Generally, the larger your room, the larger the air purifier unit you will need.

As a result, air purifiers are available in a wide range of sizes.

For instance, if you have a large room, a purifier such as the Alen BreatheSmart Classic would be a perfect match.

Conversely, for the medium and small units, the Honeywell True HEPA Allergen Remover and Germ Guardian AC4825 would make ideal options respectively.

The Noise Level of the Air Purifier

It’s agreeable, while the noise may not be a deterrent, the constant whirring can be irritating.

Fortunately, all the purifiers we have listed above are great at keeping the noise levels to a bare minimum.

The Cost of the Air Purifier

The cost of Air Purifiers ranges from about $50 to above $500. It is important however to work within your means. Nonetheless, do not feel guilty spending an extra coin for high-quality purifier. But that’s not to say that budget-friendly ones perform poorly or won’t meet your needs.

HEPA Filters vs Traditional Filters

With over 10% of the USA residents suffering from Allergies, a HEPA filter seems to cut the edge over the traditional filters. This is because of the efficiency of its filtration process compared to the traditional filters.

Because of this, HEPA air filters have gained popularity in the last few years. 

The air filter must meet the HEPA filter standards.

As such, with a perfectly functional HEPA filter, you can be assured that the air you breath would be free from 99.9% of the air pollutants compared to the tradition air filters.

Because of this, HEPA air filters have gained popularity in the last few years.

How HEPA Filters Work

To maintain such high efficiency, the HEPA filters leverage on thousands of extremely fine fibers arranged in matt-form to intercept both miniature particles and large ones.
Think of the fibers as a mesh of tangled fibers that is further folded into pleats to boost the surface area and filter life.

Benefits of HEPA Filters

The HEPA filter is a tried and tested technology, which has been approved against a high air purification standard.

That means that the certified filter efficiency is way beyond the satisfaction. Did we mention that It’s only tested at 3-micron particle size? Meaning, it can trap everything from dangling molds and allergens like dust, dog dander, and particles of cigarette dust.

Another thing to note, unlike the electronically-charged and other air filters whose efficiency reduces over time, the HEPA filters are robust such that even when dirtier, they still maintain their efficiency.

Air Purifier FAQs

Where Should I Place My HEPA Purifier?

If you only have a single purifier, you should place it in a room where you probably spend most of your time. Also, place it in a room that you deem to have the worst air quality.

As far as room placement is concerned, you should pay attention to safety and airflow.

For great performance, place it in a place with less foot traffic to avoid tripping of wires.

Also, place it at least two or three feet from the wall for maximum airflow.

One final tidbit, purifiers are most efficient with the doors and windows closed.

For more clearer information regarding safety and placement, consult with the manufacturer’s manual before using it.

How Often Should I Run My Purifier?

Ideally, it`s recommended that you keep it running throughout, particularly if you have an allergy. However, you can keep it running for 12 hours a day, it works just fine!

If you find a HEPA purifier with multiple speeds, you can activate the lowest speed when you`re away.

What Is CADR?

CADR is an abbreviation of Clean Air Delivery Rate, and it denotes the rate at which a purifier delivers air, and it`s effectiveness at filtering the airborne molecules.

The higher the CADR number, the better the air purifier.
