CalmSeaweed1360I’ve got two cats and a golden retriever, so air purifiers became non-negotiable for me. The one that’s made the biggest difference is the Coway Airmega 400S.
Cicada-fwiw, I’ve had 3 Coway airmega 400S’ running nonstop since the COVID lockdown and they’re all doing fine 5+ years later
confused_megabyteUgh. I just bought a 400S a week ago. Should I return and get the 400 instead? I do like that I can tell google to turn it on or off. But it’s almost a 200$ convenience.
They aren’t going to price match 400 price for 400S. The price of 400S hasn’t changed.
Fit-Interview-3886I’ve got two cats and a dog, so air purifiers were kind of a must for me. I’ve tried a few, and the one that made the biggest difference was the Coway Airmega 400S. It’s pricey, but it actually cleared that faint pet smell that never goes away no matter how much you clean.
IHaveASlothWhy 350/450 for large open spaces? Is my 400S not optimal for large open spaces? I have a huge open floor plan on the main floor which is where it is now.
Klutzy_Monk1880One in every room. Living room has a Conway 400s so it’s like a rectangular shape one that blows air upwards. I put a standing rack on top of it so I can dry things like ziplock bags and whatnot faster using the air it’s always blowing. lol.
lalabearosecond the airmega! I did a lot of research and my pediatrician recommended it as well (not that she’s an air quality expert, but I do trust her opinion on a lot of things!) I have a double coated dog and a cat and I really think it helps a lot. I will also say, we recently moved into a house with a lot of carpet so we bought a new Miele vacuum. My dad who has really bad pet allergies commented about how little he felt his allergies coming on the last time he was over.m
mikebrooks008I've had mine for about a year now (the 400S model) and you can genuinely feel the difference. I used to wake up stuffy every day because of city air and bad allergies, but after running the Airmega overnight in my bedroom, it pretty much solved that issue for me.
Same here! Got one for each room last year, and very satisfied with it so far.
Second the Coway Airmega! It is a beast, honestly. I’ve had it in my bedroom for over a year now, and you can literally feel the difference in air quality.
I bought the coway airmega last year and love it ever since. The filter is really easy to change and it runs pretty quietly on low settings.
