How long for new-filter smell to dissipate on the Coway Airmega ProX?

I appreciate the upvote. I was blissfully unaware that down voting was even a thing here. I am pretty new to this forum and hadn't noticed. Kindof sad that I know that now! I appreciate all your calculations.. I have done much of the same trying to find the right combo of dB, CFM, and cost. And yeah

Coway Airmega 400s

4.8-5 represents the minimum recommended Air Changes per Hour (ACH), not CADRs. CADRs are the more important metric.

Setup for 1400sqft apartment

We need to calculate room volume since your ceilings are higher than 8 feet. This is covered under the "CADR Particulate Types and Sizing" heading in our How To Choose An Air Purifier for Particulates [Comprehensive Guide]. Bedroom: 160 sq. ft. × 10 = 1,600 cubic feet volume. 1,600 cu. ft. ÷ 8 ft. =

I’m in the US, my bedroom is between 300 and 400 square feet with 12 foot ceilings

Do you need quieter operation at night? Unfortunately because of the high ceilings, this increases room volume and in turn, requires a bigger purifier. A large HEPA purifier isn't in your budget (e.g., Coway Airmega ProX or a Coway Airmega 400). Hard to recommend accurate CADRs as you don't have an

For the Love of god

Clean Air Kits does offer the option of pre-assembled kits. In choosing the Assembled - UL507 and Mesh Guard options, this significantly increases the price of the Luggables XL Ultra - 7 MobiusP to $499. Claimed top CADR for the XL Ultra - 7 MobiusP is 401 CFM. Are you able to assemble the AirFanta

Kitchen Odor Issue - PLEASE HELP!

I take it you can't have a ducted range hood installed? These exhaust cooking pollutants outdoors and would be the best solution. If you already have a recirculating range hood, try to clean the metal grease filters the best you can. Is there a window in your kitchen? I would open it and use a fan t

Air purifier to address upper airway resistance during sleep?

That's not what the data shows. I've not tried the Alen, but I've tried several other air purifies, and have found the reviews on Consumer Reports and HouseFresh.com to be accurate. And based on those reviews there are other units that provide less noise for the same clearance rate. Specifically:SPE
