I don’t know who needs to hear this in San Francisco but a dehumidifier and an air purifier changed my life.

Sure! I have the Coway AP-1512 in my living room and the Coway Airmega 300 in my bedroom. Big fan of the Coway products. If you keep an eye on marketplace or Craigslist you can get a good deal on them secondhand since so many people bought filters during the fires and end up selling them

Anyone else lethargic?

I have had a mild headache and scratchy throat since the smoke started and a bit sleepy, happens every time we get smoke like this. I use a Coway Airmega 300 in my small apartment for the past few years and happy with it, although it's one of the more expensive ones out there.

Wat te doen met rookoverlast van buren?

Ik heb een Coway Airmega 300. Als je die voor onder de 300 euro ergens kan vinden heb je daar een hele goede aan. Exact dezelfde oorzaak overigens, en ik zou nou niet meer zonder willen.

Air filter recommendations

I have a couple Coway airmega ap-1512hh in bedrooms and a Airmega 300 for my living room (available on amazon). Pay attention to the cost of replacement filters. It will be a bigger cost than the machine over time. Clean and replace them regularly. I vacuum weekly, change the carbon filters monthly

ISO: 3 air purifier for tall ceilings

Just so you know, listing room dimensions in meters is perfectly fine. Most common brands (i.e., Coway, Winix, Philips, Levoit, etc.) have very little sorbent media for gases, vapors, or odors. They are designed more for particulates, like smoke particles. Sorbent media = activated carbon, activated

Two air purifiers already do I get another?

The only 2 air purifiers that I consistently recommend to my clients are the IQAir and the Austin Air. 2 very different use cases - the IQAir is best overall, all-around, it's also very expensive. The Austin Air has a 15lb carbon block, way more than any other purifier and it's the best unit for fil

Recommendations for HEPA purifier, focus is virus reduction

Could you tell us the ceiling height in meters? This is needed for Clean Air Delivery Rates (CADRs). Unfortunately air purifiers won't be great at reducing dog hair, as it's very heavy and large compared to "invisible" pollutants like PM2.5. Hairs shed very close to the air intake will be captured,

Help Before Black Friday Sales End!

Yes. The Coway Airmega 400 sometimes drops in price enough to justify purchasing instead. Last year in the run up to Black Friday, the Airmega 400 was $349. In 2024, I also saw the price around $369 occasionally. Right now, the Airmega 400 is full price. This usually happens before a significant sal

Looking for purifier for small office with no circulating HVAC

Get the Coway Airmega 240. Its on sale and should be around the 1512 price and it's more powerful. You want to oversize it so you don't have to run at max speed. If you got the space and money the Airmega 300 is a nice unit also. Blue air is garbage!
