Airmega 100

Thanks for replying! I ended up ordering the Coway airmega 100 yesterday out of desperation 😭 wish id known about the Winix, it looks good! I hope its helpful for your brother! Ive seen those scratching stars, they look good. However I think my little one is a bit too young to be able to use something like that yet. Also theres a site called MooGoo which make skin friendly products for eczema, sounds like your brother is not a baby, so that might be worth looking into for him!

I have a couple! The AirMega 100 is the smallest I have and the air mega mighty ap-1512 is the biggest— I also have the air mega 160 which is a great midsize one if your space isn’t too big. https://cowaymega.com/products/mighty-ap-1512hh?

I just wish the Airmega 100 was like... 2 inches (5 cm) shorter in all dimensions. It seems just bulky enough to be kinda a pain to move around. The Levoit Core 300 is about the same dimensions as well. I've been eyeing the Airmega 50 because it's much smaller, but at the cost of CADR (my bedroom is very tiny though). Yes - the Levoit is not "technically" HEPA because they've not gone through the actual qualification / testing process (or something along those lines). However, people do say the filters are still very good and work as described and to the same degree as HEPA. Since I have a Coway already, I'll probably stick with the Coway lineup, just because I haven't had any issues and I've developed a trust of the brand. I'd maybe look into higher-tier brands like Allen or IQAir in the future if I really want to go all out. But after being burned by Blueair, I'm hesitant to try other entry to mid-tier brands. With that being said, I have a Levoit vacuum that I do really like and I would probably try one of their purifiers in the future.

Did you make the “IKEA enclosure” or did it come with the printer? Some of them come with ventilation w/ filters. Despite my recent post about my makeshift printer purifier, FDM is (relatively) very safe. At least compared to resin printing. I print both PLA and PETG and haven’t had any issues. I don’t have an enclosure. The only material I’d avoid is ABS without proper ventilation. With your enclosure any airborne sediment is going to either collect on the inner walls or fall back down. It’s unlikely that any significant amount of VOCs will go beyond that. People here will most likely say, “that budget is too low for anything meaningful to protect against VOCs.” But, I’d say if you’re really worried about it and want something for peace of mind (knowing that it’s an imperfect solution) you can look at the Levoit core 200, Coway Airmega 100, or other SFF purifiers. Their CADR is pretty low and they have only a little bit of carbon, but it would at least be something. The reality is smaller / more economical purifiers are going to be limited with their performance. And that removing VOCs requires (large amounts) of carbon, you’re in a tight spot. However, unless you have existing medical conditions or are incredibly sensitive to air pollutants the risk factor is pretty low. I’d personally either: 1. just rely on the enclosure. 2. Create a makeshift vent with a PC fan + carbon sheet 3. Add a small purifier as close to the enclosure as possible.

As dust particles are heavy they can settle to the floor before reaching the filter. That's not to say that filters don't catch dust. Just replaced the pre-filter on one of my machines which was saturated with dust. According to U.S. Consumer Reports (subscription required) where the top rated model got an 85: BlueAir had the best overall ratings of all manufacturers with all models in 1st or 2nd tier, 62 to 81. Best overall ratings of all manufacturers with all models in 1st or 2nd tier [https://www.consumerreports.org/appliances/air-purifiers/c29550/](https://www.consumerreports.org/appliances/air-purifiers/c29550/) Levoit: Out of 10 models tested.  3 in 2nd tier, 5 3rd tier, 1 in 4th tier, 1 in 5th tier with scores ranging from 32 to 74.  None in tier 1 (the best) where the highest rated filter rating is 85. Winex: Only 2 out of 7 Winix models rated good to fair, the rest poor       Coway: 1 Coway model rated excellent out of 9 models tested. None of the others fell in their 2 top ratings categories. One is in the lowest rating category. Ratings range from 48  to 85. Coway 100 got a 38, Airmega ProX 85, 1512 57. Winix: out of 6 tested models ratings none were in the top ratings tier. Ratings ranged to 51 to 74 where the top rated model got an 85.   2 were in the 2nd tier, 4 in the 3rd tier. Dyson: 2 models tested with ratings of 49 and 69

Do any of your coway unit make a strange rubbing notice in the motor? This seems pretty common from what I can find and I just purchased an airmega 100 for a small room and it has that strange noise. It almost sounds like a bearing or something may be impeding the path of the fan just oh so slightly.

Second vote for stainless steel litter boxes. The plastic ones really hold onto the pee smell. We also clean the boxes at least 2x daily and after every poop. We have 4 Coway Air Mega 100s in our 2000 square foot home that run continuously. We have 5 cats and when I come home, I just smell the pleasantness of our home. Sometimes I used to smell a hint of "animal" smell, but switching to stainless steel litter boxes and adding 4 air purifiers has eliminated that!

I just did a bunch of research on air purifiers and ended up with a Levoit Core 200S for my bedroom and a Coway Airmega 100 for my livingroom. Hope this helps.
