    r/AirPurifiers · Best Value Air Purifier? (Coway, Winix, Blueair, Shark, Sans, etc)

    The 2,640 sq. ft. coverage figure is for 1 Air Change per Hour (ACH). This is too low. Generally you want minimum of 4.8-5 ACH. But I think CADRs are the more important metric. The Airmega 350 is low on Dust and Smoke CADRs. Not a huge fan of the integrated pre-filter either; usually a separate permanent pre-filter is better.

    Thanks for your links. I was about to purchase the 400, but as you stated the 50’s seem to have a better CADR rating. Combined with the coupon code, it’s less expensive. Pulled the trigger this morning.

    I have both a 350 and 450. I run them both on AUTO. The 350 adjust speed automatically and seems to do a good job. At night once the room is dark, it automatically goes into sleep mode and turns all lights off. I’m on my third 450. The first two always stayed in auto mod. Finally the third one works and self adjust when in auto mode and goes into sleep mode went the room is dark

    r/AirPurifiers · Need dust Air purifier. Recomendations? Coway?

    Yes IMO the airmega would be better for your room size. The CADR and ACH for dust on the airmega is double that of the Blueair. (284cfm vs 133cfm). Honestly the Blueair is slightly underpowered for your room, but the airmega is slightly overpowered for your room. When it comes to airpurifiers always go with overpowered!

    Think the 350 and 450 just came out recently! 'm a big fan of anything that gives 360 degrees purification on the cylindrical models cause I feel like it sucks in particles better. Also love that the top has an anti-dust grill so I can clean less.

    r/AirPurifiers · Help me decide: Coway Airmega 250 or Airmega 350

    I use a Coway 250 in my master suite - 13x16 plus en-suite bathroom - and it is fine on medium 24/7. The 300/400 are for larger spaces. I’d recommend the 250 for a large bedroom, the 150 for a small bedroom, and the 300 or 400. I don’t recommend the 350 - the round design is inherently inferior to the others on this list.

    Ah, you're fine as long as they start offering the replacement filters soon... What I said are minor nits. I have no idea why manufacturers don't put carbon on the outside of circular filters just like how it's done for flat ones - maybe cost? Who knows. And I tend to buy a bunch of filters to keep in storage whenever they go on sale, so the space savings helps, but if you're just buying only when it's time to replace, the space savings isn't really meaningful.

    Just a word on filters - they are still not available yet AFAIK :(, and the design is such that the carbon is behind the HEPA unlike the non-50 series which has the carbon on the outside. My understanding is that the carbon-behind configuration leads to a shorter lifespan on the HEPA. Both seem to have a pellet-type carbon filter but an owner would need to confirm. One other note - storing round filters is space-inefficient.

    Hey! I stayed with the 350. Coway finally responded but wasn't helpful. They said they don't know when the filters for the 350 will be released. I actually reached out to Amazon (where I purchased from) and they were happy to extend my return for 3 months. The 350 comes with a 1yr manufacturer warranty, so I'm hoping they will release the filter replacement for it within that time. Or I'm returning. Lol. The 350 is amazing. Very quiet. Looks sleek and doesnt take up much space. So far quite happy with it. I also have the airmega ap-1512 for the bedrooms.

    So I literally just bought the Airmega 350 on Amazon and immediately regretted since I can't find the replacement filters for sale anywhere. Like you said, maybe it's fairly new and filters are not released yet. I tried to reach out to coway multiple times via email as well as phone (waited over 30 mins) and haven't had any luck hearing back from anyone 😫. How are you guys liking the Airmega 350? Do you think I should return it for the 450 or just start using and wait it out (hopefully) for the filters? The space I'm using it for is in the living/kitchen/dining area and covers around 2000sqft.

    That's the issue with the new Winix 5510/5520 and the Coway 350/450 series. I'm sure we'll start seeing third-party filters as these devices get good reviews and become more popular. A removable and washable pre-filter would have been nice, though that's rare with round units.

    I have the 350 and i think it runs pretty nice. Its pretty big and has a pretty huge filter which is always a plus to see in a air purifier. I made a quick video about my initial experience with it. I am hoping the fitlers wont cost an arm or leg.

    I was wondering the same thing about this unit. I am also interested in the 350 but I I don't really want to purchase it before I know how much the replacement filters are. A big factor for me is the annual cost of upkeep for an air purifier.

    r/AirPurifiers · Need dust Air purifier. Recomendations? Coway?

    I can definetly return it, I just gotta carry it there haha. It just worries me how the coway product is more marketed towards pollen and viruses rather than dust, which would be the purpose for me. But yeah, so you think the airmega would reduce dust, and my sneezing just as much, if not more, than the Blueair one?

    So glad I stumbled upon this post. I was about to pull the trigger on a mighty, but ended up using the promo code to get the Airmega 350 for not much more than the mighty! Thanks OP!

Questions fréquentes

Le Coway Airmega 350 filtre-t-il bien la poussière ?

Les avis Reddit sont majoritairement positifs sur la filtration, notamment grâce à l'aspiration à 360 degrés et au grand filtre. Quelques utilisateurs jugent toutefois ses CADR poussière et fumée modestes et regrettent l'absence de préfiltre amovible et lavable.

Le Coway Airmega 350 est-il silencieux ?

Oui, les utilisateurs Reddit le décrivent comme très silencieux. Son passage automatique en mode sommeil, avec extinction des voyants lorsque la pièce s'assombrit, est également apprécié.

Trouve-t-on facilement les filtres de remplacement ?

Non, c'est la principale inquiétude exprimée sur Reddit. Plusieurs acheteurs ne les trouvaient pas encore à la vente, et leur prix comme leur date de disponibilité restaient incertains malgré les annonces de Coway.

Convient-il aux grandes pièces ?

Les avis Reddit sont partagés. Certains le jugent bien dimensionné, voire légèrement surdimensionné pour leur pièce, tandis que d'autres rappellent que la grande surface annoncée correspond à un seul renouvellement d'air par heure, jugé insuffisant pour une filtration soutenue.
