ProX

Per the AHAM 2/3 rule, a 732 sq. ft. apartment would need minimum CADRs of 488 CFM. The most stylish is probably the IQAir Atem X. It's made in Germany. But it has a top Smoke CADR of 415 CFM. It's also very expensive at $1,399.99. The Coway Airmega ProX has a top Smoke CADR of 568 CFM. It has wheel

With a 150 ft^3 bedroom, you need a CADR of 100 to get the recommeded 5 air changes per hour (assuming 8' ceilings). You could put something like a Coway AirMega ProX in the bedroom. On silent mode, I measured it at a CADR of 170, and there's nothing wrong with overkill. And it's probably quieter th

See the AutoModerator comment - purifiers aren't good at reducing visible dust, as it's large and heavy compared to "invisible" pollutants like PM2.5. VOCs are usually difficult to mitigate with purifiers. Heavyweight activated carbon or sorbent media models are costly and very loud. Depending on wh

Going off the overall area, a 500 sq. ft. space (with an 8 ft. ceiling) needs minimum particulate Clean Air Delivery Rates (CADRs) of 334 CFM. This is according to the AHAM 2/3 rule. If you have allergies/sensitivities or high particulate pollution in general, increase CADRs. Wildfire smoke treatmen

If you're in a major city. Try Facebook marketplace. Coways are made better (quality). That's all I say. I own 2 Coways and a Levoit Vital 200s The coways weigh a lot more. Feel more study The app on the Coway is better if you decide to go smart and that matters to you. I got a used Coway Airmega 40

I almost ordered the coway 300 or 400, but was pretty sure would be louder for less cfm and more difficult to move around with its design. Thanks for confirming. Glad the Pro x works for you!

I tried the Coway 400 which has 51 Db(a) and it was CRAZY loud. Immediately packed it up and returned it that same day. So I ended up getting another ProX since I know I love everything about it (you are right about the wheels not rolling on carpet, though). I wanted to try the alen 75i, but after t

I have an Austin bedroom machine, a Coway airmega, and a gigantic Midea dehumidifier. Austin takes up a lot of space and I wouldn't say for sure that it works better than the Coway, which was less than a fifth of the price and has a small footprint. One issue with the Coway is that it has lights on

The green color is for marketing.I thought the same thing.The green hepa is used on several of their machines. On sale you could buy 3 off the Coway Airmega 450's.The Coway 350 lacks the laser sensor,wheels on the bottom,and less airflow. I bought the 450 for less than $350 and the 350 for $239. If

If you want the absolute best for the bedroom at night, you want the maximum airflow (so the air is filtered multiple times per hour) with the minimum noise, and for that you need a big air purifier running at its lowest speed. I'm currently testing air purifiers, and I've found the Coway Airmega Pr
