Airdog X8 air purifier reviewAir purifiers are great for improving indoor air. They not only remove pollutants from the air but also ventilate with fresh air from outside. Air purifiers are great for people with sinuses and allergies as they filter out dust, pollen, and smoke. Also great for you if there is a smoker in the house. Moreover, people suffering from Asthma and other breathing problems also significantly breathe better with air purifiers. However, with so many options available out there choosing one can be tedious. Therefore, in this article, we recommend one that has caught our eye, the Airdog X8 air purifier.

This Airdog X8 air purifier review will shed light on all that you need to know about this amazing product. It is an in-depth review of its pros, cons, features, why you should buy it, how to use and maintain it, the frequently asked questions, and lastly comparison with other air purifiers. The Airdog X8 air purifier is better than HEPA filtration systems and instead has a 5-stage filtration system. It collects and destroys bacteria and viruses, something that is quite useful especially ever since the global pandemic of Covid-19. One of the reasons why it stands out is because of its CADR (clean air delivery rate) of 450 cubic feet/minute.

The Good


The manufacturer states that its CADR goes up to 470 cubic feet/minute, which happens to be a high record in airflow rates for all kinds of filtration purifiers. It is also said to be the highest CADR amongst HEPA filter air purifiers. The X8 can clean a 1000 sq. feet area in just about 20 minutes


The X8 air purifier has an aerodynamic design, which means it is extremely quiet – something a lot of people want. The collecting plates of the Airdog X8 create an airflow that is of low resistance in comparison to HEPA air filters. It also requires less power for the airflow which means it does not produce much noise. It has a below 63 dB(A) noise level, even when operating on Turbo mode.

The low economic and financial cost

As the world becomes more environment-friendly people want products that are not damaging the environment. The X8 is more conscious of that as compared to the HEPA filtration system, which relies on non-recyclable fiberglass, which is also quite costly to replace. The X8 in comparison offers a lifetime washable filter so that you are not damaging the environment. It does not need filter replacement but instead is easy to clean.

Efficient air purification

The Airdog X8 can trap small particles that HEPA filter air purifiers cannot. It can remove cigarette smoke, cigarette odor, as well as other odors. Moreover, it removes pollutants such as dust, mites, and mold spores. Additionally, it gets rid of heavier particles such as pet hair, pet odors, and dander. It can also destroy germs, viruses, bacteria and removes about 99.99 of VOCs such as formaldehyde.

Control from your phone

Although it comes with remote control, the Airdog X8 is not a regular air purifier, it features smart technology as well. This means you can control the air purifier settings from your smartphone by simply downloading the Airdog Pro App. You can switch it on or off, apply child lock, analyze the air, set timers, and track efficiency as well.

The Bad

1-year free warranty

Buying something as expensive as this air purifier, one would want a longer warranty period as well. However, the Airdog X8 only has a one-year limited warranty which is not sufficient for some. While there is an option to extend the warranty period by another year, you will have to pay an extra $49. The warranty covers defective products or parts, given that they are used as per the manufacturer’s instructions.


The X8 is a much more expensive air purifier and lies towards a more high-end product that costs $1199, which is far greater than others in the market. Many will not be able to afford this, but its technology and built do justify the high price.

Heavy and large

Although highly efficient the X8 is much larger and heavier than not only other kinds of air purifiers but also its predecessors. While it is portable, but its weight and size make it difficult to carry it around with ease. It has dimensions: 30 x 15 x 15 inches and weighs 19.7 KG or 43 lbs, which requires a lot of effort to move it.


The Airdog X8 air purifier uses TPA technology (patented), which ensures that the filter removes particles of 0.0146 microns and above. This is much lower than the traditional 0.3 microns that HEPA filters remove. It kills all virus and bacteria that uses high voltage to kill 99.99% of the pollutants it takes in. Traditional HEPA filters in comparison passively filter, that is, only collect and not kill, which can itself be harmful to your health.

The Airdog X8 air purifier comes with washable plates that do not require replacing like HEPA filters. The only thing required is to wash them regularly for reuse. This allows you to be more environmentally conscious as well as HEPA filters are non-recyclable like plastic. The X8 is known for its powerful CADR of 470 CFM and can clean an area of 1000 sq. feet. This means it is great for large rooms.

The X8 is made of V-0 which is a fireproof material so it is quite safe as well. It has 6 modes and a child lock that is often necessary for people who have young kids. The ionic wind filter technology ensures high efficiency and a very quiet unit.

The Airdog X8 also comes with a laser air quality detector which is detachable and can test PM 2.5, formaldehyde, humidity, and temperature. The sensor can be removed and placed in another room to test the air quality there. It also shows an air quality index, which is the number of particles detected. The number ranges from 0-800, the lower the number, the lesser the pollutants in the air.

The Airdog X8 features a 5-step cleaning process. First, the air flows through a pre-filter screen where it collects, heavy pollutants such as pet hair, dander, etc. Then the air passes through emitter wires that create an electro field which destroys harmful pollutants that have the potential to pass in our lungs. Then at the third stage, the charged particles are killed including bacteria, germs, viruses. It is known to kill 99.87% of viruses such as influenza in an hour. Next, the particles cling to the collecting plates, which remove dangerous toxins. This is why the plates are to be regularly washed for reuse. The fifth and the last stage is at the catalytic layer, where the odors are removed, ensuring a complete and thorough purification process.

Due to the ionization filtration system, the Airdog X8 has an extremely low sound when operating. The noise level of the device is below <63 dB(A) which makes it practically inaudible.

The Airdog X8 also features color indicators as the unit can monitor the air quality in real-time. The colors allow you to judge the state of the air in any room. Green means great, light yellow indicates, good, yellow represents moderately polluted, while red shows hazardous air quality.

The Airdog X8 is a Wi-Fi-enabled air purifier. This means you can control it from anywhere as long as you have the app downloaded on your smartphone. This is great for when you are going home and want the air purifier to be on before you reach.

My Review

As someone with recurring sinus problems, I had heard a lot of hype about the Airdog X8 air purifier. I placed it in my room as that is where I spent most of my time due to work from home. Setting it up was simple, I connected it to the wifi with ease and also downloaded the smartphone app. To my utter surprise, the air quality its sensor detected in the room was awful, as the red light depicted so. After starting it, only a few hours later the air quality got better, and the color turned green to reflect the good air quality around me.

My sinus problems, headaches, allergies, all got better without taking any anti-allergies. I kept it on for almost half of the day, every day, and was surprised that my electricity bill was not as bad as I was anticipating. In the past, I had used the Molekule air purifier, but it was nothing like the Airdog X8. The TPA technology and 5 step filtering proved to be useful as they filtered not only my cigarette smoke but also the odor left behind.

A feature of the Airdog X8 that stood out for me was that it can kill viruses such as influenza at an accuracy of 99.87%. The collecting plates attract all kinds of air-borne viruses, which is quite useful especially while we are living during a global pandemic caused by a virus.  The Airdog X8’s collecting plates need to be washed regularly which is felt was an improvement from my last air purifier which required costly filter changes.

While I was glad to know it was wifi-enabled and the Airdog app was useful for many features but I still felt that the app could have been better. It disconnected a few times but overall, it was easy to use. I could set timers, change modes, and the speed from the app without having to get up.

One issue that I had with the Airdog X8 is that while it is portable, it is still quite heavy to move around easily. I wanted to also move it to the tv lounge for some time, but since it was so heavy, I required additional help to move it. Hence, I cannot shift it from one room to another with ease. That being said, its large unit is quite useful as it can purify a room of about 1000 sq feet which is quite sufficient. It is also a must-have for people who have pets. Overall, I would highly recommend the Airdog X8 to my friends and family.

Airdog X8 vs Airdog X5

Airdog X5 Air Purifier Review

The Airdog X8 is an improved model of the Airdog X5. They both share many similarities, for instance, both rely on TPA technology to collect and destroy pollutants and odors. Both can remove particles as small as 0.0146 microns. They also rely on ionization and a 5-step filtration process to make sure the air is clean. Both also use collecting plates that are washable and environment-friendly. Lastly, both have a super quiet motor fan and are perfect for people who want a noiseless unit.

However, both the Airdogs do have some notable differences. The Airdog X8, as it is a successor of the X5, is faster and more efficient. The Airdog X5 cleans an area of 450 sq feet which is a lot less than its successor’s. The X8 is also a much larger unit in size, which also makes it much heavier than the X5. Moreover, their costs also vary, where the X8 costs $1199 while the X5 costs $599. While both use the same, technology, the X8 is suited for bigger rooms while the X5 is better for smaller ones.

Airdog X8 vs Alen Breathsmart Alen BreatheSmart 75i Review


The Airdog X8 and Alen BreathSmart 75i are both highly popular air purifiers. While they both share some similarities, both are different for the most part. The Alen BreathSmart 75i too is a highly noiseless air purifier – 49 dB when powered on the high mode. Like the Airdog X8, it too has an air quality sensor that helps monitor the air. Both air purifiers remove particles and bacteria from the air by almost 99.99%.

However, while the Airdog X8 covers an area of 1000 sq feet, the Alen BreathSmart 75i purifies an area of 1300 sq. feet. The latter however runs on HEPA filter technology which only removes particles of up to 0.1 microns. It is however made of a carbon filter which helps remove odors as well. The X8 in comparison uses a washable filter and collects and destroys pollutants up to 0.0146 microns. Thus, choosing which one to go for primarily depends on which technology you prefer, one that is more environmentally friendly or not.

Airdog X8 vs Nuwave Oxypure

NuWave OxyPure Air Purifier

The Nuwave Oxypure too is a great option for large rooms as it too cleans an area of 1000 sq. feet. They both eliminate 99.99% of bacteria in the air, and it is also wifi enabled air purifier. Both are energy efficient and help save up on energy costs. Both the air purifiers are environment-friendly and both also cost more or less the same.

However, both rely on different filtration technology. The Airdog X8 uses collecting plates that run on TPA technology while the Nuwave Oxypure uses a mix of pre-filter, bio-guard filter, ozone emission filter, and HEPA carbon filter. Both however use reusable filters.

The X8 may use more advanced technology but the Nuwave Oxypure too manages to remove all contaminants and odors like smoke, allergens, pet dander, viruses, etc. Another major difference is that the X8 removes up to 0.0146 microns particles while the Nuwave Oxypure removes particles of 0.09 microns from the air.

Choosing between the two is a tough choice as both serve the same purpose, but, indeed, the X8 is still slightly more efficient.


The Airdog X8 overall is a high-end purifier that features the best technology out there. It manages to stand out from not just traditional HEPA filters but those that are similar to it as well. Its 5-step filtration, connectivity to the Wi-Fi, environment-friendly and reusable filters, as well as noiseless motor, make it a must-buy. While the initial cost may be high, you save up on the maintenance costs by washing the filter instead of replacing it each time.

Moreover, it is perfect for large rooms and makes sure the air around you is clean and fresh, without any viruses or air-borne bacteria. You can also get a cheaper deal if you get a promo code so do look out for those! Hopefully, this Airdog X8 air purifier review will help you decide whether it is made for you or not.
