We’ve been using our AirDoctor for over a year now and get a lot of questions whenever I share about it on Instagram. So I figured it would be easiest to write a detailed review post about what it is and answer all your questions.
We try to live a healthy lifestyle by eating primarily whole foods, moving our bodies, prioritizing sleep, drinking clean water, and using safer cleaning and beauty products. Air quality was next on our list!
We spend 80% of our time inside our house (we both work from home), and unlike outside air pollution, indoor air quality is something we can control.
In addition, I recently started to get allergies the past couple of years after never having them growing up (the allergens in Central Texas are nuts). From never experiencing allergies to experiencing them, it was quite the change and not fun. With this, I wanted to make sure I was limiting my exposure to them where I could.
With these things a priority, a good air purifier was next to purchase for our home. We purchased the AirDoctor 3500 (previously the 3000) after researching and from a friend’s recommendation and love it! It has been so helpful during allergy season, with having two dogs, and ensures the quality of the air we breathe is clean.
Now let’s get into my AirDoctor review!

What is AirDoctor?
An AirDoctor is a professional-grade HEPA air purifier. It filters out toxins and airborne pollutants – from dust mites, allergens, pollen, mold spores, pet dander, smoke, bacteria, and viruses. It has been tested to capture and remove airborne particles as small as 0.003 microns in size (100 times smaller than the HEPA standard).
Each model has 3 different filtration systems:
- Pre-filter – captures large particles like dust and pet hair.
- Carbon filter – captures toxic ozone, gases, odors, and volatile organic compounds (VOCs) like formaldehyde.
- UltraHEPA filter – captures 99.99% of ultra-fine airborne contaminants like pollen, mold spores, smoke, bacteria, and viruses.
AirDoctor models
There are 5 different models to pick from:
AirDoctor 1000 – circulates the air in 285 sq. ft. 4x/hour or in 570 sq. ft. 2x/hour. This model is great for smaller spaces like small bedrooms, nurseries, home offices, laundry rooms, and more.
AirDoctor 2000 – circulates the air in 305 sq. ft. 4x/hour or in 610 sq. ft. 2x/hour. Great for small rooms, medium-small bedrooms, nurseries, home offices, and more.
AirDoctor 2500 – circulates the air in 420 sq. ft. 4x/hour or in 840 sq. ft. 2x/hour. Great for small or medium rooms like kids’ bedrooms, offices, kitchens, garages, and more. This model can be wall-mounted or placed on the floor and comes with a remote control.
AirDoctor 3500 (previously the 3000) – circulates the air in 630 sq. ft. 4x/hour or in 1,260 sq. ft. 2x/hour. Great for bedrooms, living rooms, kitchens, and more.
AirDoctor 5500 (previously the 5000) – Circulates the air in 1,043 sq. ft. 4x/ hour or in 2,086 sq. ft. 2x/hour. Great for extra large spaces, high ceilings, and open concepts.
The model you choose will depend on the space you need it for. The 2000, 3500, and 5500 have a wifi connection version available for a price increase.
We use the 3500 and move it back and forth from our kitchen/living room (open-concept space) to our master bedroom. This works well for us right now and we will get another one in the future.
How does AirDoctor work?
AirDoctor works with an automatic sensor and the fan speed adjusts depending on what is in the air around it. It is constantly running and filtering on auto mode. When it picks something up, the fan speed will increase to remove the particles. Once removed, it will adjust back down to auto mode.
The light indicator on the machine will tell you the air quality around it. Low speed and blue light mean good air quality. Medium speed and orange light mean moderate air quality. High speed and red light mean poor air quality.
How often to change the air filters
It is recommended to replace the filters every 6-12 months (depending on the filter).
Cleaning them regularly will help maximize their use though! The machine will tell you when the filters need to be replaced, which is super nice as you don’t have to remember. To replace them, remove the cover and place them inside in the correct order.
How to clean air doctor filter
Your filters will last longer if you clean your pre-filter regularly. I recommend using a small vacuum to remove the dust, hair, and other large particles. Doing this every month or so will help maximize their longevity.
How to reset air doctor filter light
When one of your filters needs to be replaced, a light will come on. After replacing it, you will need to reset the light to let the machine know a new filter has been installed. To reset your AirDoctor filter light, press the ‘Auto’ and ‘Dim’ buttons together for 3 seconds. The ‘Clean Filter’ light will flash 3 times and then turn off completely, indicating the unit has been reset. The reset will only affect the filter light that is on and not the other one.
Are the filters expensive?
The price of the replacement filters will depend on the model you have. They range anywhere from $45 (smallest model) to $125 (largest model) per filter. When buying in packs from their site, they discount them and it costs anywhere from $80-320 a year. I find this price to be reasonable.
Does the air doctor come with filters?
Yes, when you purchase your AirDoctor, it comes with filters. You will then have to replace them going forward.
Is it loud?
When the AirDoctor is on auto mode, I don’t find it to be loud and don’t even notice it running. It does get loud at the highest setting when it detects toxins or particulars that need to be filtered, but it is only for a short period (about 15-30 seconds, depending on what it is). Our AC, the vent over the stove, and the fans in the bathrooms are much louder.
For reference, here is the noise in decibels:
- lowest speed (auto mode) – 30-40 dB
- highest speed – 50-59 dB
The noise will depend on the model so keep that in mind. I have heard that the smaller models can be louder due to the filter being smaller and where the fan is placed.
Does it help with odors?
Yes, AirDoctor can help with odors! The carbon filter helps with odors and gases. Since we cook a ton, I have noticed smells don’t hang around as long and aren’t as strong.

My honest AirDoctor review
I enjoy our AirDoctor and am very happy with our purchase. Here are some pros and cons I have with it:
Pros:
- professional grade with 3 filtration stages – pre-filter, carbon/VOC filter, and an UltraHEPA filter. Having a true HEPA filtration is important. Some air purifiers don’t have a carbon filter either.
- their UltraHEPA filtration captures 99.9% of particles – it removes particles 100x smaller than the HEPA standard and typical HEPA filters!
- high CADR rating (152-534 depending on model) – CADR stands for Clean Air Delivery Rating and depends on how fast your purifier can clean the air compared to the room size. For a large room, you would want a higher rating. It is best to have an air purifier with a CADR of at least 80.
- third-party laboratory testing
- automatically adjusts to the surroundings with its sensors
- it is very affordable compared to other brands – this is especially true when you use my discount link!
- tells you when you need to change the filters rather than having to guess or remember
- fairly aesthetically pleasing and fits in well (it’s not ugly!)
- ability to dim it so no lights are on
- not connected to Bluetooth or WiFi – while this might be a deal breaker for some, we prefer it this way.
- easily portable – they are fairly lightweight and can easily be moved from different rooms if needed.
Cons:
- some models can be louder than others – this is what I have heard as I only had the 3500 model, but the smaller models can be louder. I don’t find mine to be loud at all.
- the fan is loud on the highest setting – this is just temporary though while it filters the air.
- need to buy new filters every 6-12 months – I find this to be fine and expected, but something to note if thinking about yearly costs.
Is AirDoctor worth it?
In conclusion, I think AirDoctor is 100% worth it! We are constantly bombarded with massive amounts of toxins in our modern lifestyles and air quality is so important! This is especially true if you live in an area that doesn’t have good air quality (major cities) or an area prone to fires. I think AirDoctor is one of the best for quality, performance, and price point.

Hello,
It is 2025 & I was able to use your link. The price went up but it was still cheaper then what they offer it for. So thanks for your link. I have an air doctor already & I like it. My 3500 is messing up and I need to contact air doctor but I did buy another one in case they don’t warranty this one which they should. So we will see.
Yes, their prices have gone up recently, I will need to update my post to reflect that. They have great customer service and I would reach out to them about your older one and see what they can do. I hope they can help!
I cleared the cache, but the link doesn’t work for me.
Hey, Zac! It seems to be working for me on the individual air filter pages. It should also be discounted when you add it to your cart. I would try maybe an incognito window if you are still having issues. I hope that helps!
Discount doesn’t link.
Hey, I double-checked and it is working. You might have to clear your cache if you recently visited the website. I hope that helps!
