ng stray pieces of styrofoam for 30 minutes after unboxing. It slid out, I removed two pieces of protective styro caps, and unwrapped the shrink wrap. I took off the plastic wrap from the filters (which were already in place so I didn't have to read a book of instructions first to figure out where to put them). Then I simply plugged this sucker in, and it worked on auto right out of the box. It was like unboxing an Apple product -- so intuitive, so seamless, so simple. Kudos to manufacturers. And of course, as first impressions go... it looks good. So I love it even more because it's pretty.

Aesthetics aside, it is also built well... and perfectly sized. I attached photos to show that it's not too tall, nor is it too deep. It is a bit shorter than my nightstand, which is of an average height. It's a bit on the wide-side, but you can position it however you see fit. It does need about a foot on the right side to allow for proper air flow, and probably a good idea to keep the front end free & clear since the "circle" is from where it pulls in air... but I found this guy could be positioned in many places throughout my home without being an eyesore. I have it in my bedroom currently, but I plan to buy one for my family room as well, and maybe the basement also. It really does work. My bedroom is often very stuffy, especially in the winter when we have the heat temperature set to 73 degrees -- I like it warm & toasty, but my nasal passages feel otherwise. I do suffer from pollen allergies, as well as mild allergies to dust mites, grass, ragweed, mold spores, and pet dander (although I still have 2 shed-heavy fur-babies.) But my allergies are never bad enough to warrant any real attention, I just suffer through it since they're pretty mild. HOWEVER, I keep saying mild when in all reality, I didn't know the difference between no allergy and mild allergy until sleeping one night with this purifier running. Man what a difference. My nose was not all dry and cracked up feeling on the inside. It also was not runny or scratchy, which is how it often feels after running my humidifier all night (which I run to keep my nose from feeling so dry!) This machine does not mask the issue, or dampen it, or freeze/cold draft it away.... it CLEANS THE AIR. I know, I know... it's hard to imagine, but boy is it easy to feel. I slept for the last 2 nights like a newborn baby. Granted, I've only had it for 2 days but the difference from walking into my bedroom vs the other rooms of my home, cannot be ignored. My home isn't particularly old, or stuffy, or dirty, or dusty. Yes we have pets, but I am a Dyson maniac and we have a brand new HEPA HVAC filtration system; we have our ducts cleaned regularly; and, there are no smokers or other reasons for contaminated air (at least that I can find.) However, when plugging this thing in... it ran a blue and then purple light for a bit on auto, but then changed to RED (which freaked me out a bit as it sounds rather aggressive). And it ran that way for about 10 minutes. I left it to its job, and when I returned a little while later, it was back to a blue light and I could barely hear it running anymore... but the air did in fact feel lighter, crisper, and easier to breathe. It felt much like the very first time I walked onto my hotel balcony in Vancouver, Canada and took in a giant breath. It just felt... clean.

Air quality is a legitimate thing, and having poor air to breathe makes life a less tolerable for people with allergies or lung issues. Again, not something I suffer from necessarily, but I appreciate the cleaner air this provides nonetheless. So I cannot imagine how much better breathing could be for someone that does have serious allergies, asthma, or other breathing troubles. I would say this gem is a no brainer, if you do. But even if you don't, you'll still notice the difference after plugging this guy in and letting it run for about the first hour.

I do think the auto feature could become a bit of a power monger as I have never witnessed it turn off after being on auto as if to say "okay, I'm done. All clean." So I do set the timer feature when I'm not going to be upstairs and I shut it off when I'm leaving the house for awhile. Another thing to note is that there are studies about potential harmful effects to lungs when using the UV and ion cleaning features. It is recommended that you only use these settings when not in the house as breathing in UV treated air is said to be harmful as a result of O3 air, similar to breathing in air high in ozone levels. So I only set my purifier with these features when not in the room.

I can't yet speak to durability or filter tolerance, but they are priced reasonably enough that changing once or twice a year would be totally acceptable. I will update if I find that longevity or level of purifying impact worsens, or if cleaning/upkeep isn't as great with this machine moving forward, but for now... I am a Coway air purifier believer.

** UPDATE - after 7 months of constant use, I will say that my initial reactions were still pretty accurate in that this purifier does do what it claims to do. I notice that it is reactive to smells, smoke and other air-purity issues when they are occurring, even when I am simply cooking sausage or something extra smokey or fragrant in the kitchen -- while I have this unit upstairs in my bedroom, which is a considerable distance from the kitchen (bedroom in front of the house on 2nd floor, kitchen in the back of the house on the 1st floor.) So I know that it indeed works because I can hear it begin to run rapidly when I accidentally burn something or even when making bacon or something that has a smell or odor. I also know that it is filtering dust and pet hair, because both of my Coway purifiers (I have one upstairs and the tower unit downstairs) needed HEPA filter replacements at 6 months. The manufacturers suggestion is 6 months for the carbon odor filter, and 1 year for the thick, HEPA filter.. but my HEPA filter was so dirty at 6 months that the "change filter" light came on for the tower unit, so I figured I would change this 1512HH unit at the same time, and it definitely needed it. The filters were both clogged with so much dirt, dust and pet hair.. I couldn't believe this stuff was floating around my house for it to grab. In fact, even strands of my hair were in the filter! And my hair is pretty long, well below shoulder-length. I figure it must have sucked it in from the floor. Pretty cool purifier... I still give it 5 stars and 2 thumbs up after 7 months of use.

抛开设计方面，它也很好......并且尺寸合适。我附上照片表明它的高度和深度均为适中。它比我的床头柜略短，高度很平均。它有点宽，但你可以根据自己的需要来放置它。它确实需要大约一英尺的右侧以允许适当的气流流动，并且可能保持前端开放而透气是个好主意，因为“圆圈”是它从空气中拉出的......但我发现这个可以放在我家的许多地方，而不仅仅是一个位置。我现在在卧室里有它，但我打算为我的家里再买一个，也许还有地下室。它确实有效。我的卧室经常非常闷热，特别是在冬天，我们将温度设定为73华氏度 - 我喜欢温暖的烤着面包，但我的鼻腔道则不然。我确实患有花粉过敏症，以及对尘螨，草，豚草，霉菌孢子和宠物皮屑的轻度过敏（虽然我仍然有2个尚在襁褓中的婴孩。）但我的过敏症从来都不足以得到任何真正的关注，我只是忍着，因为它们非常温和。然而，在所有现实中，我一直说温和，我不知道过敏和轻微过敏之间的区别，直到这个净化器在我睡觉的时候运行了一晚。我的鼻子并没有干燥和破裂的感觉。也不是流动或沙哑的，这是整夜运行加湿器后经常会感觉到的（我开着加湿器是来保持我的鼻子湿润的！）这台机器没有掩盖问题，或者阻止它，或冻结、冷冻它......它净化空气。我知道，我知道......很难想象，但男孩很容易感受到。我像刚出生的婴儿一样睡了2个晚上。当然，我只有2天，但走进我的卧室与我家的其他房间的区别，不容忽视。我的家没有很旧，或闷，或脏，或尘土飞扬。是的，我们有宠物，但我痴迷于戴森，我们有一个全新的HEPA HVAC过滤系统 ; 我们定期清理我们的管道 ; 并且，没有吸烟者或其他污染空气的原因（至少我可以找到。）然而，当插入这个东西时...它会在汽车上运行然后发出蓝色和紫色的光，但后来变为红色（因为听起来相当激进，我吓了一跳）。它运行了大约10分钟。我把它留在那里自己工作，当我稍后返回时，它又恢复了蓝光，我几乎听不到它运行的声音......但实际上空气确实感觉更轻，更新鲜，更容易呼吸。这感觉就像我第一次走到加拿大温哥华的酒店阳台上，并且喘不过气来。它感觉......干净。

空气质量是合乎标准的，呼吸空气不足会使过敏或肺部疾病患者的生活难以忍受。同样，不是我必然会受到的影响，但我很喜欢它提供的清新空气。所以我无法想象对于有严重过敏，哮喘或其他呼吸困难的人来说，呼吸会有多好。如果你这样做，我会说这个是没脑子的。但即使你不这样做，你仍然会注意到这个插入后并让它在第一个小时左右运行后的差异。

我确实认为自动功能可能会成为一个强力监控器，因为我从未目睹它在关机后关闭，好像说“好吧，我已经完成了。一切都很干净。”因此，当我不打算上楼时，我会设置计时器功能，当我离开房子一段时间后我将其关闭。另外需要注意的是，当使用紫外线和离子清洁功能时，有关于肺部可能有害影响的研究。建议您不要在室内使用这些设置，因为据说O3空气会吸入紫外线处理过的空气，这与臭氧水平高的空气呼吸类似。因此，当我不在房间时，我只将这些功能设置为净化器。

我还不能评价耐用性或过滤器耐受性，但它们的价格足够合理，每年更换一次或两次是完全可以接受的。如果我发现使用寿命很长或净化冲击水平恶化，或者如果这台机器向前移动时清洁、保养做的不是很好，我会更新，但现在......我是Coway空气净化器的信徒。

**更新 - 经过7个月的持续使用，我会说我最初的反应仍然非常准确，因为这个净化器确实做到了它声称要做的。我注意到，当它们运行时，它会对气味，烟雾和其他空气纯度问题产生反应，即使我只是在厨房里烹饪香肠或者多余的烟熏或香味的东西 - 而我在卧室里将这个东西放在楼上，距离厨房相当远（2楼房子前面的卧室，1楼房子后面的厨房。）所以我知道它确实有效，因为我不小心听到它开始快速运行然后在烧一些东西，甚至在制作培根或有气味或气味的东西时。我也知道它是过滤灰尘和宠物毛发，因为我的Coway净化器（我楼上有一个，楼下有塔式单元）需要在6个月时更换HEPA过滤器。制造商的建议是碳气味过滤器需要6个月，而厚的HEPA过滤器则需要1年......但我的HEPA过滤器在6个月时非常脏，因此塔式装置的“更换过滤器”灯亮了，所以我想我会同时改变这个1512HH单元，它肯定需要它。过滤器都被污垢，灰尘和宠物毛发堵塞了......我简直不敢相信这东西漂浮在我的房子周围以便它抓住。事实上，我的头发甚至都在过滤器中！我的头发很长，远低于肩膀长度。我认为它必须从地板上吸入它。非常酷的净化器...使用7个月后我仍然要给它5颗星，举起两个大拇指为它点赞！

rty room, so I figured it wouldn't take long to filter; the thing ran on high for close to 40 minutes and then medium for another 20! I began to have doubts and contemplated returning it, as it seemed to be cycling from medium to high back to medium constantly without my perception of a change in air quality. I decided to give it a week to see how I felt before returning....and I am so glad I waited. Three days later I was waking up able to breathe through my nose with no issues. I suffer from allergies that worsen while laying down and had resigned myself to either suffering with that or elevating my head, neck, and shoulders with pillows. This air purifier has definitely been a blessing! When I replaced the odor filter after 6 months per protocol, I was again sold. There was so much dust and dirt on the first filter screen, less on the odor filter, and none on the HEPA filter. I hadn't been using the ion setting, as I wasn't really sure it did anything, so I decided to turn it on and see if I could tell a difference. Two months later I noticed dust collecting just inside the gray ring on the front cover, but didn't think much of it. Another two months I noticed even more dust but thought it was because of some work being done in the hallway outside the bedroom. Finally, after another two months when it was time to replace the odor filter again, I was blown away when I opened the front cover. The screen was covered with dust and dog hair (my dog had only been in the bedroom once for about 5 minutes and no shaking or scratching), the odor filter was gray from all the dust, but still nothing on the HEPA filter.

There is the option to control the fan speed: low, medium, high. Low makes almost no noise and I sleep with it on low every single night without being bothered. Medium is a more noticeable noise, but still not unbearable. High, however, is pretty loud. I leave mine on Auto 24/7 and have no issues other than the light given off by the buttons on top. They are easily covered with a towel (or tape or thick paper) if light is bothersome while sleeping. Occasionally it cycles to medium, but quickly goes back to low. The Eco setting is nice, but with my allergies I prefer to keep the unit running all the time with the Auto setting.

TL;DR This is a superb air purifier that performs fantastically. I HIGHLY recommend!!

可以选择控制风扇速度：低，中，高。低速几乎没有噪音，我每晚都在低温下睡觉而不被打扰。中速运行有明显的噪音，但仍然无法忍受。然而，高速运行时很大声。我选择了Auto 24/7，除了顶部按钮发出的光线之外没有任何问题。如果在睡觉的话光线很麻烦，它们很容易被毛巾（或胶带或厚纸）覆盖。偶尔它会循环到中速，但会很快回到低位。 Eco设置很好，但是对于我的过敏，我更喜欢使用自动设置让设备始终保持运行状态。

最后：这是一款极好的空气净化器。我强烈推荐!!
