Main trade-off
Medify Air MA-112 V3.0
The cabinet is large and the two filters have a stated 3,000-hour or roughly four-to-five-month life.
Head-to-head
Medify MA-112 vs AirDoctor 5500: AirDoctor adds Auto but gives up 38 rated smoke CFM
The short answer
Choose the MA-112 for the highest verified smoke airflow. Choose the AD5500 when automatic sensing and a more explicit carbon/VOC filter path are worth giving up 38 CFM.
Before you choose
The reasoning and the trade-offs
Automatic mode can settle the choice
Only AirDoctor AD5500 Classic has a positive checked result for “Automatic mode” in this pair. If it is required, the decision is already made.
What this is based on
The conclusion follows the checked yes or no difference for the exact configurations compared.

About this comparison
Two very-high-airflow purifiers compared on smoke CADR, automation, gas filters, size and running costs.
The practical choice turns on smoke cadr and automatic mode, then on the constraints in your own setup.
Winner by situation
Start with what you need it to do
I want it to react on its own
Its onboard sensor can change the fan speed automatically. Check the model facts for what that sensor measures.

Wildfire smoke gets indoors
For smoke cadr, Medify Air MA-112 V3.0 records “594 CFM” and AirDoctor AD5500 Classic records “556 CFM”. The published output matters only when the room, surface or workload needs the extra headroom. It does not prove better results by itself.

The needs that actually separate these two
Medify Air MA-112 V3.0 has the stronger fit for “I will move it between rooms” and “I do not want an ionizer”. AirDoctor AD5500 Classic has the stronger fit for “I want it to react on its own”.
How we reached this conclusion
This compares the current strong and useful fit assignments for the exact products. It does not turn them into one overall score.
One choice covers more of this shortlist
AirDoctor AD5500 Classic covers 4 of the 4 buyer requirements attached to this comparison. Medify Air MA-112 V3.0 covers 3, missing “I want it to react on its own”.
How we reached this conclusion
This count uses the current strong and useful fit assignments for the named products. A requirement counts once, and no arbitrary score is added.
How much choice there is for “I want it to react on its own”
55 of 70 checked air purifiers match this need. AirDoctor AD5500 Classic is in that group. Medify Air MA-112 V3.0 is not.
How we reached this conclusion
The count filters the current category dataset for a strong or useful fit on this one buyer need.
Finding models for “I want the air cleared quickly” and “I want it to react on its own”
14 of 70 checked air purifiers cover both “I want the air cleared quickly” and “I want it to react on its own”. AirDoctor AD5500 Classic is in that group. Medify Air MA-112 V3.0 is not.
How we reached this conclusion

Medify Air MA-112 V3.0
Fits these inputs594 CFM of verified clean-air delivery gives about 14.8 air changes per hour here. The 5 ACH target needs 200 CFM.
AirDoctor AD5500 Classic
Fits these inputs556 CFM of verified clean-air delivery gives about 13.9 air changes per hour here. The 5 ACH target needs 200 CFM.
This uses maximum-speed, pollutant-specific CADR and a five-air-changes-per-hour target. Quieter settings deliver less clean air. It does not substitute raw airflow or a one-change coverage claim.
Choice A
Medify Air, MA-112
MA-112 V3.0
A very large dual-filter cabinet whose standout feature is unusually high verified particle airflow, not software or furniture-friendly size.
- Best matched use
- A very large open room where raw smoke airflow matters more than compact placement or smart controls
Checked facts
- Medify publishes a 594-CFM smoke CADR, dust above 600 CFM and pollen above 450 CFM.
- The exact model is rated for 891 square feet at five air changes per hour.
- Four fan speeds, a timer, child lock and casters are included without an ionizer.
Choice B
AirDoctor, AD5500
AD5500 Classic
AirDoctor's large dual-filter model combines high verified smoke airflow with automatic sensing and a documented carbon/VOC stage.
- Best matched use
- A large open room where high particle airflow and automatic operation matter more than cabinet size or filter cost
Checked facts
- AirDoctor publishes a 556-CFM smoke CADR for the AD5500.
- The cabinet measures 28.75 by 16 by 16 inches and weighs 33 pounds.
- Dual prefilters, dual carbon/VOC filters and dual particle filters sit behind automatic particle sensing.
Meaningful differences
What changes the fit
| What changes | Medify Air MA-112 V3.0 | AirDoctor AD5500 Classic | Why it matters |
|---|---|---|---|
| Smoke CADR | 594 CFM | 556 CFM | The published output matters only when the room, surface or workload needs the extra headroom. It does not prove better results by itself. |
| Automatic mode | No | Yes | This changes how many steps the user handles and how much of the routine is automated. |
| Gas stage | Carbon composite | Separate carbon and VOC filters | This identifies what the treatment path is built to capture or reduce and what recurring care it requires. |
What you give up
Every choice has a cost
If you choose Medify Air MA-112 V3.0
- There is no sensor, Auto mode or app.
If you choose AirDoctor AD5500 Classic
- The 33-pound, 16-inch-square cabinet is substantial and has no published noise range.
