If i were re-buying for a large space, id consoder trying to get my hands on the airmega 240 but it seems to be out of stock https://cowaymega.com/products/airmega-240 Or the airmega250 https://cowaymega.com/products/airmega-250?srsltid=AfmBOopMFwg2kp4uHXLg6CFV-JDBNwspkjiAVJNPEuy2c7nXEakKbirz which is also often sold out apparently. we have an airmega 150 in each bed room and they are awesome https://nl.coway.com/products/airmega-151?srsltid=AfmBOoo63FcMmUk2KnsIu0J6h55Q6nfrxzyrCVz05W6ltykwF44dmMC3q We have the airmega mighty in our large living dining kitchen area https://nl.coway.com/products/airmega-mighty-1?variant=39686230671432 it works well but is uglier than the 240 and 250 that are currently sold out. You can find more information on this sub https://www.reddit.com/r/AirPurifiers/ including threads that will explain what you can and cannot expect from an air filter (not do much heavy dust removal unless you buy units much much larger than the minimum, how to calculate the needed air turnover rate for your case and space, etc...)
Idk anything but I have a levoit and coway. I prefer the coway bc it has an ionizer and hepa. I don't think the levoit does. It gets rid of smells more than anything. You'll still get hair build up.
I have the air mega 200, I linked it below but you can probably find it on Amazon or Walmart cheaper. https://cowaymega.com/products/airmega-200m?srsltid=AfmBOopQz9sdFtqEVRtH7iB_IcS4QjmIzJotussspAV4Afzq2-i6j2O_ The levoit I have is a vital 100s https://levoit.com/products/vital-100s-smart-air-purifier?variant=43165376381079&country=US¤cy=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&utm_source=google&utm_medium=cpc&utm_campaign=us_gg_pmax_ap_eg_lofu_04172024_br&tw_source=google&tw_adid=&tw_campaign=21192607823&gad_source=1&gad_campaignid=21192608285&gbraid=0AAAAACKUb62oakHBhZoQgq1c0Mmuj417A&gclid=Cj0KCQjwlrvBBhDnARIsAHEQgORTFzYnRddupRtN4i8NXUIU6zlY7c3vRd0GhalmX3pqqsfdTgVqZs0aAgwXEALw_wcB Random note, if there are any local companies around you that do liquidation auctions you can snag air purifiers pretty cheap. I bought the levoit from an auction company in Cleveland called 'Online Liquidation Auction' for $24 and it was basically brand new (retail $139). I just thought I'd mention it because I'm a cheap bastard!
The [Coway Airmega 150](https://en.coway.com/products/airmega-151) does have lower CADRs than the [Airmega Mighty AP-1512HH](https://en.coway.com/products/airmega-mighty-1), but the latter is louder. Some find the Mighty too loud on the highest airflow speed. The [Levoit Vital 100S](https://levoit.com/collections/air-purifiers/products/vital-100s-smart-air-purifier) has similar CADRs to the Airmega 150. Do you have a maximum budget and what is your room's size (length x width x height)?
I own a Winix C909 and am very happy with it. But the feedback I've read in this subreddit and seen in reviews is that Coway makes better quality units than Winix. The only Coway purifier quality issues I've seen are rattling/balance issues with the Airmega Mighty AP-1512HH. That and some people complain Coway filters off gas.
I'm a big fan of the Coway Airmax line and got my original recommendation from another pet community. I have both the big square shaped guy and the smaller cylindrical one for a smaller guest room and both keep the smell way down.
It definitely helps with the dander/dust, but it's unfortunately most effective when you change or clean the filters pretty regularly. Don't let Amazon bully you into getting the name brand filters and get the off-brand ones, it doesn't know the difference. I have two short haired but large dogs and one small cat so we have a lot of fur flying around. I clean a good deal of it out of the filters each time so it's surely doing its job! I definitely feel a difference when the filters are new or clean. When they're in the top intensity mode they're a little loud, but most of the time they're whisper quiet at level 1.
I have one of these, but I think multiple individual smaller units are more effective. Their Mighty is $150 on their website.
1) I have a Coway 1512HH Mighty and 2 of the Winix 5500s... and they are both really good units for particle filtration for the money. I've also dealt with a lot of customers with both units, through the years, who were quite happy with each of them. 2) Are you Chemically Sensitive? 3) If not, I’d try to get another Coway 1512HH Mighty to see if it offgasses less. It is currently on Amazon at a really good price. I’m new to Reddit, so IDK if I’m able to mention the pricing specifics of units. 4) I am currently not a big fan of Filter Monster replacement filters - I think they are possibly not as good as the filters coming from the actual manufacturers. As, I got one that is supposed to be the exact same filter as the one I have in my Austin Air Healthmate. However, it was about 23% lighter in weight and didn’t seem to be of the same quality… so, I’m not 100% sold on the quality of the Filter Monster brand. 5) The Winix 5500 was recently replaced with the 5510 so, that would probably be the next unit I’d consider, in the same price range. I think the Coway Mighty is sealed a little better than the Winix… but if you can’t use it - you may be happy with the Winix solution…
I ended up getting the mighty and it's been great! I'm not an expert but would recommend it. It has helped a lot with hayfever I think. I don't find it overly loud on setting 2 (which is what we leave it at). But yeah if you can keep the door closed I would have thought that would help a lot! I'm now looking for a bigger one for the living room downstairs. From memory I paid around £190. There are deals here and there where you can get it a bit cheaper (like £20 cheaper or so) but didn't want to wait as needed it asap. Good luck!
Was comparing the sales and planning on getting another Coway air purifier for my house cause I loved the previous two we got. Seems like you get a better deal on cowaymega.com. Dropping this here for anyone who needs!
Wanted to clarify this is the Coway Airmega Mighty or Coway AP-1512HH Mighty air purifier, the same one Wirecutter has been pushing the last ten years or so, in case anyone was confused!
