Clean Air Optima CA-507 specifications
The numbers that matter first, then every fact by group. As published by the maker or the shop we read it from.
Consumables: The filter lasts about 4 months.
Cleaning performance 4 facts
- Clean air delivery rate (CADR)
How much clean air the purifier delivers an hour, measured with smoke, dust and pollen. A higher figure cleans a bigger room or the same room faster.
- 350 m³/h
- CADR measured to
The test the CADR comes from. AHAM AC-1 and the DOE test are independent and comparable. A maker's own test is not.
- Not stated
- Room size we compare on
The room size where the purifier changes the air 4.8 times an hour under a 2.5 m ceiling, worked out from its CADR. We use it so every model is compared on the same rule.
- 29 m²
- Room size the maker claims
The room size the maker states. Makers use different rules, so we show it but never rank on it.
- 70 m²
Filter 3 facts
- HEPA filter class
How fine the filter is. True HEPA and H13 catch at least 99.97% of particles at 0.3 microns. HEPA-type is a weaker claim with no test behind it.
- H13 HEPA
- Filter layout
Whether the particle and carbon layers are one filter or separate ones. Separate filters let you replace only the part that is spent.
- One combined filter
- Activated carbon filter
A filter of activated carbon that takes out smells and some gases. It does not catch particles.
- yes
Running costs 1 fact
- Filter life
How long the maker says a filter lasts, in months of normal use. A filter that is spent cleans less.

- 48.9 cm
- Weight
What the purifier weighs. It counts most if you move it from room to room.
