Airmega 450

I wouldn't focus on coverage ratings, as brands like to inflate them. With a big number like 1,700 sq. ft., this is probably at 1-2 Air Changes per Hour (ACH) which is too low. Generally you want a minimum of 4.8-5 ACH. Even so, the more important metrics are Clean Air Delivery Rates (CADRs). And ye

Going by the AHAM 2/3 rule, your 15' x 15' x 10' bedroom needs minimum Clean Air Delivery Rates (CADRs) of 188 CFM. The Coway Airmega 250S can achieve that, although I don't know if you have allergies, high pollution levels, or other circumstances that need increased CADRs. The Coway Airmega 450 doe

I assume the 500 sq. ft. you mentioned in another comment is an open space without walls. (You need a purifier for each room, as they can't overcome walls and doors.) If the 500 sq. ft. is open, you would need a minimum of 334 CFM CADRs. These figures are for normal pollution levels. You may have el

I see, thanks. FYI: unfortunately purifiers aren't good at reducing visible dust and pet hair. Both are large and heavy compared to "invisible" pollutants like PM10, PM2.5, and PM0.1. See the sticky post at the top of this subreddit and entries from our FAQs wiki page: I need an air purifier for dus

With dust mite allergens, you can try reducing relative humidity (RH) below 50% for a prolonged period. (Another study recommended RH of 45% or lower if I recall correctly.) This should kill them off. For the bedroom: of the two, I would tend to choose the Coway Airmega 350. You'll definitely need t

I assume you're an expatriate living in the US? Most Americans don't use "whilst". 😉 Unfortunately if you have high levels of particulates (pollen, dust, mold, etc.) and gases/vapors/odors (including VOCs), you generally need two types of air purifier. This is because particulates-focused purifiers

Wait until the Coway Airmega 450 goes on sale. This unit moves a ton of air if you can deal with the noise.I picked up a white one for about $350 around Christmas.I think the 400 was on sale a while back for $349.

Yep, should be adequate for the space. In the USA, Airmega 350 debuted just under a year ago. It seems to have good reviews so far. Keep in mind the Clean Air Delivery Rate (CADR) listed for it applies to the highest airflow speed/setting only. Lower settings have lower CADRs which reduces cleaning

Unfortunately if there is wildfire smoke, Smoke CADR needs to equal your studio's area (assuming an 8 ft. high ceiling). So Smoke CADR should total 900 CFM. FYI: the Smart Air Blast MKII composite CADR of 950 is in m3/h. This coverts to 559 CFM. Do you already own the Airmega 450 and the Airmega 240
