Style: 400 WHITE
I bought a 300 for each bedroom on sale and, when they went on sale shortly after, a pair of 400s to cover the rest of the house. Pre-tax ~ 320 and ~ 370 usd, respectively. The 400 is about an inch bigger in each dimension, so size feels the same. The 400 is around 25pct more powerful. 1560 vs 1256 sq ft stated in this listing more or less tells you that, and CADR is there if you dig around each product page on Coway's site (3 CADRs per product). Above were facts you could look up. Now for the stuff I couldn't find before buying. (Note: Coway failed to mention the button differences and denied the sound differences existed when I interrogated them on email repeatedly and then on phone about any/all differences.) The 400 is a lot louder on 2 speed. My phone app standing near the front of the units says 50db and 55db, respectively. With respect to pitch, the 300 sound is a low whoosh and the 400 has a higher pitched undertone. Two household members agree these differences are clearly there but don't mind either sound much; one person can sorta stand being in a room with the 300 on 2 speed but not at all the 400. The 400 is similarly louder than the 300 on 3 speed, though i only measured 2 speed as i wouldnt plan to be in the room with them on high. Both are whisper quiet on 1 speed. The two units have the same power button and same light/timer/etc buttons on the left. But the buttons you really use the most are different. Look closely at the pix and you can see the 300 has one button (between the power button and the s for smart) while the 400 appears to have no buttons there. Actually, the 400 has a series of non-labeled buttons in a little arc - separate buttons for smart, night, 1, 2, 3. I thought, "oh this is much better" when discovering this upon hooking up my first 400. But, definitely there are more failure points and these buttons seem each to be inherently less likely to last forever than the type of button used on the 300 (where i have to press/beep several times instead of just once to get the setting i want). Then I noticed that the 1 speed button on that unit only worked less than 10pct of the time. I returned that unit and got a replacement 400... that was immediate and before I used them at all and when I just knew I wanted the larger model for the non-bedroom rooms; having had both models for a week or two now I'm not sure which i'd go with if I had that decision again. My cats activate the buttons on both units when the stand at the units like a counter, and when they use them as "butt coolers." There is no control lock. I plan to cut up a 1/10" plastic sheet from HD and drill/countersink button access holes that are big enough for fingertips but not big enough for paws. I might also lightly spraypaint the underside of that plastic, as the indicators are very bright and cannot be dimmed. On both, the lights (except the smart/night/1/2/3 lights) turn off at one button press. You can't turn off the beeps. Both need the prefilters cleaned weekly or so - takes seconds to pop the sides off and do it with the hand brush attachment on a vacuum. In my limited experience, the 400 has a better sense of smell - it kicks on more often in smart mode. (I have all units set to maximum sensitivity.) On both, you can use a smart plug if you want. It starts on the same setting as it was when it lost power. On the 400, I probably nevwr will but you could use those button bots if you wanted - eg, one for 3 speed and one for 1 speed. This wouldnt work on the 300 since it's just one button and couldn't keep track of the setring (unless you also had a camera, i guess...). One comment that isnt a comparison of 300 and 400...After my very brief experience with Mila prior to finding Coway, I have zero appetite to try a purifier with built-in connectivity. Mila was much louder than either Coway, buttons werent responsive, manual speed had a known bug that it would change itself, power up took minutes not seconds and didnt resume previous speed, it couldnt smell anything even if i shook out pine pellet cat litter right next to it, and a few other things. The reviews have me convinced that Coway smart is also not fun. I can get all the convenience and control I could possibly claim to need - and a device with less in it to break or annoy - with a $7 smart plug (or without one and let it run on smart or 1 or 2 nonstop). I doubt there I'd a product is prefer. Gimme control lock and dimming on the speed lights and it is perfect. EDIT after a few more weeks: another 400 was also defective. Rhythmic, loud noise on 1 speed that would sometimes find its stride/resonance/whatever and be heard all around the house. Amazon limits qty of 400s per account; due to defects, I had to switch to my spouse's forgotten, linked account in order to buy the 4th one. 300s: 3 for 3... 400s: 2 for 4. Also, I figured out how to reduce the volume overall and practically eliminate the high pitched noise on the 400... either add very thin weather stripping to coway filters (HD has a 17' roll of 1/8" foam that is very compressible, will try applying that on next filter change but should work).... or replace them with cabiclean filters for 400 which are a snugger fit and 1/3 the price but otherwise identical (I did this for now, bought backup cabicleans in case something changes with price/availability and set aside the originals). I started using smart plugs as timers for all units; the blue light on front defaults to on which can be annoying in bedrooms, but easy to dim with some tape and a piece of copy paper (folded in half and then thirds seems perfect) after popping off the front cover. Lastly... the 400's far left light is a white ring that starts to disappear as an indicator that time to vacuum the pre filters is approaching; the 300s turn orange (either orange or not, no gradual indicator) when that circle on 400s is still more than 2/3 full. I do all 5 once one goes; in my house, they all appear to (equally) need it at that point.

Style: ProX Beige
Initially purchased an Airmega ProX and Airmega 350 to supplement our older Alen Breathesmart flex. Surprisingly, the larger ProX is the quietest of the three. It emits a soothing sound on level 2 and on level 1 it’s hard to hear it running when more than a few feet away. As someone that struggles with chronic allergies and allergy related headaches, the air feels very clean and our cat has been sleeping a short distance from the ProX due to the soothing sound. The main downsides of the unit are the filter costs and the size, however, Coway has been selling filters discounted on their website. The difference in build quality and sound compared to the 350 was enough for us to return the 350 and swap it with a second ProX for our oversized bedroom. We run both now at 24/7 on level 2 no problem, not audible during work meetings or anything.

Style: 400S WHITE
I love a lot about this air filter. I really like the smart features. I originally thought they would be gimmicky, but after living with it for a few weeks I have experienced the value. I love that it detects the airborne contaminants, and increases air circulation to clean the air. I’ve noticed that it increases air flow during high traffic and vacuuming, among other things. I like that I can check the app for air quality, and I can see past air quality as well. I like that the filter knows when it’s bedtime and decreases airflow, in order to keep noise pollution down, for quiet tearfulness. Now on to effectiveness. We have a nearly 3000 square foot new construction home. It’s about three years old. Most of our air contaminants likely come from area construction, as well as a year round growing season, with year round pollen and similar contaminants. My oldest child has had a persistent hack for the last couple of years. I would not really call it a cough, so much as a hack. Every few minutes he would do a throat and lunch clearing cough. It never seemed short of breath, just seemed to be clearing an irritant. We took him to doctors, who suggested everything from allergies to asthma. We sort of ruled out asthma because he is athletic, and has no issues out working other children, and displays no unacceptable shortness of breath, other than what you expect, and recovery times are quicker than normal. As a previous asthma sufferers myself, that does not resemble asthma to me. We opted to try daily allergy medications, and they seemed to help some, but did not eliminate that dreaded hack. Now I said all of that to say this. Since we added this filter, we hardly ever hear him clear his lungs. I’m actually surprised, because I assumed it would take much longer. I figured he had been doing it long enough that it was a habit by now. But after a few days of filtering, his symptoms diminished, and after a week or so, he almost never does it. Now our home is nearly double the size of the the filters rated coverage area. But the design of our home, I think, allows one unit to work. Our central air unit has only one air return, and it is at the blower unit. This is located centrally, upstairs, in a closet with a vented door. The area around that closet is sort of an open landing area, that opens to a large family room. I think what is happening is that the filter can clean large volumes of air, that then get circulated through the house. The dirty air is then pushed back up to that open area, and filtered by the unit. The unit can tell when air is clean or dirty, and increases, or decreases circulation, accordingly. Anecdotally this seems to be a successful test, eliminating our primary concern. The side benefit is the remainder of our family is now breathing cleaner, healthier air. It just took one sensitive member to illustrate the need. I wish I had known this would solve the problem, and I wish I had done it sooner. I expected to need to units to have a successful result, and I’m so pleased that one unit does the job. Not every home may have the same results. Some may actually need two units to do the job. Also, I opted to shop the amazon warehouse deals and save a bunch of money. I bought a used acceptable condition unit. It arrived in a generic box, but everything was still protected by the factory foam, and cling wrap. Everything appeared new, and worked perfectly. If you want to save s big percentage, I highly suggest checking out the warehouse deals. If your displeased with the condition, Amazon has a very generous return exchange policy. My filters in my unit looked brand new and unused. But if I were concerned, new filters are about $100, so you could still have significant savings, even if you opted to put brand new filters in it right away. At first I was put off by what seemed like a high filter cost. Then I recognized what I was spending on allergy medication each month, for one child. The filters provide clean, allergy free air for the whole family, at a fraction of the cost of allergy medications for one child. By reducing our allergy medication costs, we can replace filters as needed, an no added cost. I would have thought building a new home would prevent these issues, but the other new construction in the area, seems to exacerbate the issue. I also weighed the option of an Aprilair, or air bear system on our central air unit, but I was concerned about the designed air flow for our system, and any disruption could shorten the central air life, increase energy needs, and decrease overall home comfort. Those air filters work great for a system designed and tuned for their use. But for a system designed for a more or less open fiber filter, it could cause problems. So I decided a stand alone filter would be the better option. Also those air handler systems that go on your ariconditioner unit, are not usually helps rated. The AIRMEGA 400s is. And it is constantly monitoring, and cleaning the air. It also uses no harmful ozone. I’m an ozone fan, and I own an ozone generator. But I like to use it in specific situations, under controlled conditions, when all occupants can be out of the house. I don’t want ozone to be a part of my primary home air filtration system. Others may have different priorities, and I encourage you to research the benifits and precautions, and choose according to your needs and priorities.
