Your place in the market
Check the current evidence before buying
Verify the exact model suffix, genuine filter, placement, electrical use, ozone setting, returns, warranty and service
01
Before the shortlist
The first four answers do most of the work
A useful ranking starts only after the constraints specific to this market are clear.
- 01
What room dimensions, ceiling height, doors, airflow and particle source define the air volume and target air-change rate?
- 02
Which fan speed and sound level can run continuously enough to deliver the intended clean-air flow?
- 03
Are particles the main problem, or is meaningful gas and odor adsorption required beyond a thin carbon sheet?
- 04
What exact replacement filters, annual cost, sensor, app, privacy, ionizer, placement, electrical and warranty conditions apply?
02
Market education
Read only as far as you need
The path changes with your research stage. Each guide is built around a decision that removes part of the market.
01orienting
Size from CADR, room volume and speed
Use the tested particle flow and a tolerable continuous setting rather than a one-air-change room claim
02comparingCompare filters, sound, sensors and ionizers
Separate particle, gas, automation and ozone questions and keep every claim attached to its method
03comparingPlan placement, filters and smoke readiness
Treat replacement media, airflow, electrical use, source control, returns and service as one ownership plan
03
Buying paths
The shortlist covers different ways to own the product

Market language
The terms a useful comparison should define
- CADR
- Clean Air Delivery Rate, a tested particle-cleaning airflow for a named pollutant under a stated method; it is not the fan's raw airflow
- Air changes per hour
- How often a clean-air flow equals the room volume; the result depends on CADR, room volume, mixing and the speed actually used
- Sorbent media
- Activated carbon or another material intended to adsorb some gases; media mass, chemistry, contact time and loading matter separately from particle CADR
- CARB listing
- A California ozone-emission compliance listing for an air-cleaning device, not proof of cleaning effectiveness, health benefit or universal tolerance
