No, Dyson is one of the worst! The HP09 has terrible Clean Air Delivery Rates (CADRs). They just know how to market effectively. As Rule 4 and the AutoModerator comment repeats, it's helpful to know the ceiling height. I'll assume it's 2.4 meters. 60 m2 x 2.4 = 144 m3. For rooms measured in meters,

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.

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.

Fakt ? Mám černý stůl. Coway Airmega 300 čističku která se bere jako už celkem upper mid range produkt. Osobně mi nepřijde že je rozdíl ve frekvenci utírání prachu mezi zapnoutou a vypnutou.

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

Luckily 500sq ft isn’t too big, so you can probably get something like the Levoit 300 for the main room and a smaller one for the bathroom. My advice is don’t get something too small for your main room, or it won’t work. And if you want serious air cleaning, then something large and rated for 2x or

I personally use 3 Winix 5500-2 units, one in each bedroom, a Coway Airmega 400 for the larger living area with kitchen, and a Coway Airmega 300 for my smaller living area and really like my setup. We have 2 cats, a dog, and 4 small birds, so they all definitely work overtime, but the air is very cl

I've never had a problem with Coway or Winix models except that the filters need to be changed every couple of years. Coway Airmega 300 is good.

Since you listed measurements in feet, I'll be using the AHAM 2/3 rule for minimum Clean Air Delivery Rates (CADRs). This assumes an 8 ft. high ceiling. See the AutoModerator comment as well. A 12' x 25' room needs minimum CADRs of 200 CFM. A 12' x 12' room needs minimum CADRs of 96 CFM. These CADRs

I'll use the 90 m3 measurement so I'm not underestimating any subsequent values. The Clean Air Delivery Rate (CADR) should be at minimum 3 times your room's volume when measured in m3. This is for normal pollution levels or user scenarios. In this case, 90 m3 × 3 = 270 m3/h CADR. Note: CADR values a
