AP-2015F Airmega 400 Smart Air Purifier (Covers 1,560 sq. ft.), True HEPA Air Purifier with Smart Technology, White

Due to my allergies being worse than usual this year, decided to do an air quality overhaul on the home. This included an upgraded whole-house filter on the AC/Furnace (Merv 16), a Coway Mighty unit for the bedroom and this larger Coway Airmega 400 for the rest of our open floor plan. Immediately I notice the build quality of this unit is really nice. Tight fitting parts, nice design details (magnetic doors, for example). Everything visually looks and feels high quality. It is a step up from the Coway Mighty, for sure.. The filters on this unit are impressive. One side is a honeycomb filter media loaded with carbon pellets for filtering out odors, with the other side being the HEPA. Once I had these unpacked, I installed the pre-filters and replaced the exterior covers and got this unit up and running! Operation is very easy and straight forward. I don’t mind the touch-screen style buttons at all, it’s actually quite nice. Buttons are responsive to touch and work perfectly. You have the power button, fan speed selection (with ECO mode) and a button for turning the lights of the unit on/off. Note, at first I thought my power button was broke until I read the short and concise manual which does state to hold your finger on the power button for 2-3 seconds to power off. Worked like a charm! So keep that in mind if you skipped the manual, like me… Oops! Sound level wise, it is practically silent on low. Even sitting right next to it, you can’t really hear it. Medium picks up a tiny bit of volume, but it’s still very impressive how quiet it is. You start feeling quite a bit more airflow at this point, it seems to the be the sweet spot in terms of air being moved and the volume level if you are occupying the room. On high, it’s still honestly not bad but can be a little distracting depending on what you are doing. The sound is simply just air moving, no motor or other offensive types of noise. For those who really like white noise, it’s quite soothing in my opinion! We have a split level with an open floor plan. We have the unit located on our 2nd floor in the corner of the room. The Airmega really pushes air around, you could feel a draft in the other rooms when the unit is on high. Very happy with that, it really circulates the air well. The air quality sensor responds very well to stimuli when the air quality drops. When my dog jumped on the couch nearby, it kicked on to a higher level. When I dusted window blinds on the opposite side of the room, it detected the change in air quality and quickly kicked on high. Even blowing out a candle in the next room, it was detected. Very happy with it’s performance. The air absolutely feels cleaner. Perhaps it is a placebo effect, but there is no denying that this unit is great for removing allergens and odors out of the house. I am very happy with this unit and would highly recommend it!

Holy grail air purifier. So easy to use and makes a real noticeable difference. Extremely user friendly and easy to clean too. Also appreciate that it is not a huge eye sore. Very quiet. Worth every penny.

This is a fabulous purifier. It's so quiet, I wasn't sure it was on. But then I cooked something in the kitchen and it cranked up. It's really helped by allergies. It's not very heavy. I have to remember to turn it off when I light incense.

I’m going on my 5th year using this device daily, it has rarely ever been turned off. I run it on the setting below the highest, always. I will say it isn’t quiet but it isn’t loud. It creates a nice white noise that is adaptable. I have replaced the filters in it every 9-12 months due to a dust issue living near a lot of farm land, plus I have all hardwood floors, no carpet. I have a small dog in the home who often has company and Im a smoker. Over all I feel like the air is fresh and it helps immensely with dust and dog hair! I never smell my dog or cigarettes in the home. When I come in after work and the house has been closed up all day, I can smell my plugins right outside the front door which is a great thing. I clean the pre-filters weekly and they normally have a good coating of dust and dander that I spray away down the sink. In the summer I sometimes find mosquitoes on the pre-filter! I hit the main filters with the Dyson about once a month as the fine dust does collect and prevent air flow. I have to admit that the original filters did a better job and lasted longer than the off-brand ones that I purchase for about $25 per set but the savings outweigh the loss of quality by far as they are quite comparable with fit and filtration. The sensor is very sensitive to the environmental changes and air flow will increase with change. I love that the front and back are also detachable by sliding upwards and can also be easily removed to be cleaned like the 2 magnetic sides that cover the filters. It has a night mode and a timer feature although I rarely use either. My home is a 1300 sq ft ranch style therefore the layout is somewhat boxy. The device is centrally placed however I believe the lay out of my home would be most benefited from an additional unit as the bedrooms still collect quite a bit of dust but are somewhat partitioned except the doorways. I will definitely purchase another Conway product when my budget allows as I’m very pleased with the reliability and ease of the airmega 400 however it was considered an investment at its price point.

Elegant and super quality feel. I like that it ramps up when it senses particulate in the air. It's very quiet at all other times. Would buy again.
