aesthetic/stylish air purifier with high CADR / efficacy recommendations

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

Air Filter Recommendations for Los Angeles air quality!

Haven't used either. I own a Winix C909. The Winix C610 is going to be better because the CADRs are higher. The Levoit Core 200S will be very weak for your space and pollution concentrations. Build quality on the Winix is likely better too, although some of their models develop bad motor bearings af

Alen 45(or 75) Vs Allerair Med 1

Re: dust, this is frequently asked. Air purifiers aren't good at removing visible dust as it's large and heavy compared to something like PM10, PM2.5, or PM0.1. See the sticky post at the top of this subreddit and our FAQs wiki page entries: I need an air purifier for dust. What should I buy? Why is

Recommendation for 200ft bedroom with no budget

Air purifiers aren't very good at reducing visible dust because it's relatively large and heavy. You'd have to hugely oversize a conventional HEPA purifier to capture more visible dust, which your budget would support. Whether you feel this is worth doing is another matter... You should be looking a

Which one is better for cat owners?

No, one Winix C610 wouldn't be enough. The Winix 5510 would be underpowered too. I would base my choice off of Clean Air Delivery Rates (CADRs), not Air Changes per Hour (ACH). See the AutoModerator comment about the AHAM 2/3 rule. For an open 500 sq. ft. space, minimum Clean Air Delivery Rates (CAD

First air purifier purchase

Ideally, you should have a ducted range hood that exhausts to the outdoors. Cooking pollutants (including odors) are best handled via exhaust ventilation. See our FAQs wiki page entry "Which purifier should I buy to control cooking particulates or odors?". Are you looking to remove chimney smoke par

Air purifier to address upper airway resistance during sleep?

That's a MUCH better response that the first one you gave me, since it actually has some substance, rather than just calling something "shit". So let's talk. Your point about a good seal being needed to keep the fan blades from getting dirty is an excellent one. Do all the major purifiers (Coway, Wi

The Best Air Purifiers Right Now?

I have 6 Alens. 2 x BreatheSmart 75i, 2 x BreatheSmart, a T500, and a Paralda. I like them. They are quiet, the sensors (on the 4 bigger ones) seem to be accurate and ramp up cfm when air quality calls for it. I live in the lightning capital of the world... God's Lightning Rod, FL. I had 2 older one

First Impressions - Coway Airmega 400

Thanks for the input! I just finished measuring the rooms in my lil’ 2br house. There’s a galley kitchen, with just a counter separating it from the living/dining room space. So I’m hoping one unit is enough for that combined space. If I did it correctly, the space is just under 400 sqft. Each bedro

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
