Pros

  • I recommend the 240 over the 250 as it's essentially identical in terms of specs but cheaper.

  • Our master bedroom (400 square feet for the suite) has a Coway 250 in it and we love it.
  • Coway 250 in the master suite
  • I decided to not overthink the green HEPA and I bought to Coway 250 on black Friday sale. It arrived yesterday and I LOVE IT. ... I can feel the air quality difference even having it on level 2 because it’s oversized for the room I have...

Cons

  • I was looking at the airmega 250 which is in my budget and would cover my needs but both models (the 250 and the 300) seems to have the green HEPA filter which is claimed to be harmful by some.
  • Everything on them other than CADR should be nearly identical. Although the 350 does have 360 degree air intake whereas the 250 has side/front intake.
  • I know the 250 has lower cleaning rates (I don’t remember the exact terminology 🤦🏼‍♀️), and is louder.
  • The 250 has lower CADRs than the Airmega 240.
  • By contrast, the Airmega 250 uses activated carbon pellets which are greatly preferred. But the Airmega 250 does not have a significant capacity for removing odors or other gases.

Parent context: Thank you for the informative response! I think I may go with the 250. It was one of the ones I’m eyeing. Reply: I love it. Looks retro futuristic, has a pleasant noise output, and makes the air VERY CLEAN. Filters last longer than most and it has both a washable pre filter screen AND carbon grid which can be vacuumed off.

I decided to not overthink the green HEPA and I bought to Coway 250 on black Friday sale. It arrived yesterday and I LOVE IT. ... I can feel the air quality difference even having it on level 2 because it’s oversized for the room I have it in. ... I also love that it has a cleanable prefilter and how long the filters last!

Coway AirMega 150 (bedroom) and 250 (larger main room) - these have a very good CADR for the room sizes, and I have had good luck with Coway filters in the past.

Yes. I have one and love it. The smart/auto mode is intuitive. It’s quiet and handles my 65 sq meter living space kitchen really well. I’m happy with it.
