  • Designed to clean spaces up to 1,256 sq. ft. in 30 minutes

Knowing CADR filtration capacity of the purifier is not the only attribute in choosing a purifier - I looked at purely CADR across the 300, 300s, 400 and BlueAir 211i max-
I used their specific company website for the information- I am posting a rough estimate from my search.

Model #: 1st # smoke, 2nd dust, 3rd pollen

300: $289 prime
CADR (Clean Air Delivery Rate)
296 (Smoke), 299 (Dust), 390 (Pollen)

300s: ~$400 - $461
CADR (Clean Air Delivery Rate)
285 (Smoke), 306 (Dust), 339 (Pollen)

400: ~ $300 with Amazon prime 10% pretax as estimated low price
CADR (Clean Air Delivery Rate)
285 (Smoke), 358 (Dust), 450 (Pollen)

BlueAir 211i max: ~ $180 pre tax at low
~ 410 across the board I assume since not itemized

The BlueAir 211i max stands out when comparing relative value - form function to price cost

Honorable mention is the
Shark - subjectively this throws a similar amount of air as the Coway 400 (if that helps at all)
Total: $155-170 pretax range at low
Shark - Air Purifier 4 with Anti-Allergen Multi-Filter & Advanced Odor Lock, 1,000 sq. ft. - Charcoal Gray

CADR Shark Air 4 (HE402)
From Rtings.com
Air Cleaning Rate
369 m³/Hour
Average Final 0.3 µm Concentration
100 particles/L

Hope this info helps.

I'd personally spend the extra $50 and get the 400 which is still on sale for $340. Apparently, the 400 is an inch larger in all 3 directions and weighs 3lbs more (21 vs 24lbs). 400 cleans an additional 300 sq ft twice per hour than the 300, too. Otherwise, I think operationally they're the same. I'm by no means an expert on air cleaners or these two in particular. I just snagged the 400 and am happy with it so far.

II think they also need to be "SMART" from a technological perspective as far as features and controls from a smart phone. Maybe they can start getting in other features like whatever data can be obtained from such units to see how the unit is functioning over a period of time.

Definitely this or the air Mega 400 over anything blue Air. The Coways are super heavy duty, which you can tell from how heavy they are. You also only need to change the air filter once a year compared to at least twice a year on the blue Air. Pre filters easily taken off and washable on the coway as well

The only real advantages to the Coways are that they don't use a cloth prefilter (if you don't have pets, this is good. Also, the mesh prefilter are easier to clean) and they use active carbon pellets in their filters instead of the traditional carbon filters.

The BlueAir uses much less energy and is cheaper.

The 400 is definitely a good air purifier. I regret not buying a second one and buying a Levoit instead.

Is Molekule not even in the conversation next to this or Blue Air?
