We have an Alen Breathsmart Fit50. The Alen is the best air purifier we have owned but it's pricey, replacement filters are pricey and after a few years the driver belt will loosen and you will experience reduced airflow. It has a lifetime warranty but only in the US.
Instead of replacing the filter for the Alen we decided to buy the Coway for a little more than the price of an Alen filter.
We got it over the Coway Ap-1512HH since the Coway website has posted nearly similar airflow for the AP-1216L and we liked the slim profile better.
Quiet: at the lowest setting is super quiet, silent, much quieter than the Alen at the lowest setting, the downside is that it barely moves any air. Great for sleeping but you would have to use it at the 2nd setting to get it to work as well as the Alen and at the 2nd setting the noise level is comparable to Alen's lowest setting.
Cheap: costs a little more than an Alen replacement filter.
Small: with its tower like shape it takes less space and it's less visible in the room.
Smart(?): if you remove the front cover you realize that it's 2 small air purifier stacked, I guess they were able to keep cost down by not creating custom parts and filters, smart.
Some people complain about the night mode, it's really 2 small lights, you will not have a problem unless you need a pitch black room to sleep.
Air quality sensor: similar to other reviews it was working fine out of the box for the first couple of days, changing colours and cycling to different speeds in auto mode. But after a while it's been staying at blue/clean no matter what so we had to resort to keep it off auto and on a manual setting to make sure it was actually purifying the air. We ran a test and move the Alen in the same room and the Alen cycled through all of its settings. I guess the cost cutting continued all the way to the air quality sensor.
This is really the only con, but at the price of an Alen filter you can't complain and in a few years when the belts on the Coway loosen, we'll just buy another one for the price of a filter, not the most environmental friendly option but yeah...
Ordered this to combat all the smoke from the Camp Fire here in California. While this product is working as advertised, this is absolutely inaccessible if you are blind. The whole unit is run from a smooth touchscreen with no haptic feedback, buttons, or anything on the device to get it up and running without sighted help. This is very frustrating since the flat, visual-only interface is not mentioned at all in the product description and is the very definition of exclusive design, making it impossible for the blind and visually impaired from using this device independently. My Hamilton-Beach True Air filter for smaller rooms just has a physical dial which works perfectly, and I wish that this Coway tower had physical buttons so I could use it without help. I don't care how "cool" the interface looks, I just needed a purifier with the strength, quiet operation, and versatility for cleaning a larger space and was extremely disappointed with the lack of accessibility from the Coway designers. Shame on them.
I'm torn in the decision to keep this or return it. After reading the manual it states "This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm." How can an air purifier have a chemical that can cause a health risk? I enjoy the sq.ft that it covers, the sleek modern design and on low to medium fan setting it's barely noticeable that it's on. Although there is a function to turn off the light this only turns off the indicator of the quality of air; the other features such as fan are on. I also will point out that the manual mentions that it should have it's own designated outlet - not shared with another device. Not having many outlets in my home causes this can be an issue.
Overall this is a very nice air filter for a small bedroom. My only gripe would be with the Hepa filter fitting rather loosely. Unfiltered dirty air can and does make its way around the sides of the hepa filter and you'll need to vacuum out the dust. I have other units from Germ Guardian and the Airmega also from Coway. Those units solve this problem by using foam rubber as a gasket around their hepa filters. Coway needs to do that for the hepa filters for this unit, it's a simple fix. In the meantime I was lucky to have some leftover weather stripping laying around. I used it to create a gasket around the hepa filter so it fits snugly.
I’ve notice it kicks on to high levels automatically when a friend that smokes is over. That’s cool, but I don’t really notice a major difference in odor or dust/dander control. I’ve taken the filters off multiple times to see if they’ve filled up and find barely anything. I manually put it on high after dusting and vacuuming, and still don’t notice a huge difference. Our sinuses haven’t really improved either. Quite possibly was a waste of money, but I’ll give it some more time.
Lights are bright, might want to turn lights off at night, unless of course you want to use as nightlight. High is very powerful, takes up very little space. Very easy to read because the controls are on top!!!! Had to return because within a week the on/off button didn't work, and the other controls quit working. Very sad, because I really liked it. Don't think I'll buy again.
I do not recommend this device for a bedroom unless you're okay with bright lights. Even though they advertise that you can turn off the ring light, the remaining indicator lights *will* light up your room and are quite annoying.
Positive things: - device is quiet - looks nice - has a 12hr timer
Negative things: - cannot schedule the purifier - indicator lights (not the ring light) are too bright - Coway seems to like lighting up bedrooms :\ :\ - if you disable the ring light the ionizer is also disabled (this is a design flaw as mentioned by another reviewer) - purifier is quite large (tall and wide)
I got the Coway AP-1216L due to its aesthetics and also the fact that it cleans air up to 330 sq ft. However, after using it for a couple of days, I really don't notice a difference with the air quality, and the sensor doesn't seem to work as it never turned purple. I have read reviews that mention that the sensors are not sensitive, although you can adjust the sensitivity level. Once my gas was leaking and it was still blue, I even tried farting next to it once, and it still stayed blue (indicating that the air quality is good). I guess it does not detect odors, only the amount of dust particles in the house.
Another thing to note is that the air gets sucks in from the front from both sides, and flows out on the right. I'm not sure if this is good for air circulation as I don't smell fresh air as the Revital Air Purifier I have for my bedroom (and that one's under $65, which is a good deal (It's a 5-in-1)
However, this Coway unit is so beautiful and blends so well with the whole interior of my living room that I'm wondering whether I should return it and exchange it for the one that looks like a big iPod nano.Both work in room sizes over 300 sq ft and that one even has an eco mode, This 1216L however, looks more high tech and futuristic since it uses a touch panel, and matches my Dyson fan.
