Air Doctor 2000 Review

AirDoctor 2000 air purifier

Air Doctor 2000 is very similar to AD3500 in design and features. It is smaller and covers smaller areas suitable for bedrooms, offices, and more.


  • Compact and Good-looking design
  • Powerful for its size and weight
  • Built-in handles


  • It could have quieter, lowest fan speeds

Air Doctor 2000 Design and Size

It is the smallest air purifier of the AirDoctor brands, with a height of 18′. The weight is the same as Air Doctor 1000, but this one is easier to move around thanks to built-in handles.

The design is very similar to Air Doctor 3500. Air intake from the front, output through the top. Touch controls are on the top, so they are very easy to operate.

It looks nice and clean. You can place it everywhere in your room, and it will look good.

AirDoctor 2000 Filters

Get AirDoctor 2000 Air Purifier replacement filters 10% off

AirDoctor 2000 has a pre-filter attached to a Carbon/VOC/Gas filter. Behind them is the UltraHEPA filter.

Filters are the same as other AirDoctor air purifiers, just smaller in size. They can eliminate everything from the air – from large dust particles to the smallest viruses and bacteria.

Cleaning and maintenance are simple and easy – clean pre-filter monthly and change Carbon and HEPA filters when needed based on filter change indicator lights.

Air Doctor 2000 Room Coverage

AirDoctor 2000 can cover rooms up to 600 square feet, cleaning air 2 times per hour.

Using it better in spaces up to 300 square feet is recommended. It can clean 300 sq. ft. spaces 4 times every hour or once every 15 minutes.

AirDoctor 2000 Noise Level

As it is the newest model in the AirDoctor family, I thought it would be the quietest, but it is not. Even more powerful and larger, the AirDoctor 5500 is quieter.

Don’t get me wrong; it is not loud. It’s not quiet either, especially on fan speeds 1 and 2.

So it doesn’t stand out as the quietest or loudest. It goes somewhere on the industry’s average.

Air Doctor 2000 Power Consumption

Air Doctor 2000 consumes only 11 watts on the first fan speed and 110 on the highest.

Considering most users will use it in the auto mode, energy consumption will be somewhere in the middle because it will change fan speeds according to air dirtiness.

That’s similar to other brand models and less than the market’s average.

Air Doctor 2000 Features

It has the same features as model 3500 – auto mode, filter change indicator, dim lights, timer, and more. More about these can be read in the AirDoctor review article.


Air Doctor 3500 has become one of the best-selling air purifiers on the market, so AirDoctor made similar looks and features containing air purifiers – Air Doctor 2000.

I wanted to see something new, for example, wifi, a remote control, or an app, but AirDoctor went the easier way.

Yes, they made yet another great air cleaner – it looks good and works great, but there is no surprise.

So, if you like AirDoctor 3500, this one is your choice for smaller rooms or spaces where you need to save space and put smaller air purifiers.

If you want everything above and the mobile app, go for the AD2000i version.

Which One Is the Best?

Considering all four models are unique, it isn’t easy to pinpoint one. However, based on your requirements, the fact remains that each AirDoctor model is the best.

For example, pet owners can take any model; they all eliminate pet dander and odors.

Air Doctor 1000 and 2000 are the best and most economical if you are looking for a small option.

Ideally, considering that most have a reasonably medium house, Air Doctor 3500 has proved to be the best for most people; for larger spaces, pick Air Doctor 5500.

As per the user manual, it is recommended to change the UltraHEPA filter once every 12 months and the carbon filter twice yearly.

Unfortunately, AirDoctor carbon filters can’t be cleaned. I bet you have tried or know someone who did, but that can damage the unit and decrease indoor air quality. So don’t do that.

  • Which AirDoctor model is suitable for allergies?

All the AirDoctor models are tested and designed to attack allergies. Therefore, you can pick any one of the three models. However, if you have a smaller space and are looking for a better performer, Air Doctor 3500 is the best bet.

  • Does the air doctor remove mold?

Yes, an Airdoctor can dismiss mold spores. The air doctor must have a HEPA filter to entrap airborne mold spores.

The air purifier must have two other characteristics: an Activated Carbon filter to eradicate mold odors and a germicidal UV-C light to stop mold spore reproduction.

  • Does the Airdoctor remove odors and VOC?

Yes, it does. AirDoctor can also remove formaldehyde and other very tiny contaminants.

It is an excellent idea to use specific types of air sanctification technology as it applies with direct mediation to terminate the smell’s origin, whether it is mold or a strong kitchen smell.

For example, the Molekule (PECO) technology is the only air sanctification solution that eliminates combustible organic compounds (VOCs), the airborne chemicals that make up nasty odors in your home.

  • How loud is the AirDoctor?

AirDoctor uses premier Professional Whisper Jet fans, which are 30% lower than the fans found in regular air purifiers. The lowest noise level is 39 dB, and the highest is 59 dB.

The product’s WhisperJet fans are 30% more silent than fans found in ordinary air purifiers, ideal for those who want friendly home surroundings.

  • Which AirDoctor model is the quietest?

As per the design, all machines are infused with WhisperJetfan, so all are silent. However, it also depends on the size of your room. So buy the best suitable model, and you can be assured of silent performance.

  • How many AirDoctors do I need?

Having one on each level in a multi-level home would be more suitable. AirDoctor is adequately strong to purify all aurae in a normal-sized room on time every hour and in smaller spaces multiple times per hour.

  • Can AirDoctor run 24/7?

Yes, and I recommend setting it on auto mode. This way, it will adjust the fan speed automatically based on the dirtiness of your indoor air. Also, when running 24/7, it will save on energy costs.

  • Is the Air Doctor safe?

USDA and FDA approved the safety level of chlorine dioxide gas. JFCFA of WHO and FAO have also confirmed its safety. The negatively charged ions delivered by air ionizers are not dangerous.

However, they will tempt and entrap the charged particles, including the potentially toxic particles in the air, which, if untreated, could lead to respiratory infections or throat irritation. This will make the air safer for a healthful atmosphere.

  • Does the Air Doctor Produce ozone?

AirDoctor ejects no ozone with the ionizer off and less than 0.005 parts per million with the ionizer on. Some ionizers are best for designing high-level ozone.

The AirDoctor ionizer only improves the ozone level by a very small amount. While they may terminate small particles, they may be inadequate in clearing large particles. Electronic air cleaners can produce ozone, a lung nuisance.

  • Where is Air Doctor manufactured?

The company was founded in 2016 and works from its headquarters in Van Nuys, CA. Laboratory results confirm that AirDoctor extracts 100% of tested viruses and bacteria down to 0.003 microns.

The air doctor also terminates impurities and pollution like pollen, smoke, mold, VOCs, and dust mites.

  • Where should I put my Air Doctor Air Purifier?

Placing your purifier near a window or doorway is typically your best bet. Another reason to place purifiers near areas with high airflow is that moving air has enough energy to lift dust, mold, and many other particles, which can then be distributed around your house.

  • How long does the Air Doctor take to ship?

Most in-stock products are dispatched from the warehouse or manufacturer within 24-72 hours, Monday- Friday. Custom or unique size demanded products can take longer.
