COWAY Air purifier for Home Bedroom, ECARF Quietmark Certified 20dB Sleep Mode, Removes up to 99.999% of Harmful Particles down to 0.01 µm for Allergy, Smoke, Pollen, Pet - Airmega 150 (White)

It has an automatic sensor and good air purification technology, it automatically detects when the air quality is poor and starts up on its own, it is quite quiet and the lower setting and even on the higher setting it is not too much of a nuisance. It is very light although it is not small but also not big in size, it's very good quality and value for money especially on the discount that I got meaning it cost about £110. It does not disturb my sleep at all in fact it has helped with sleep considerably because I can breathe better through my nose due to the reduction of allergies. I saw this written in a lot of reviews and was dubious however it is true, I wish I had got this sooner. Overall the functionality is good it is quiet and works as expected and looks like a good quality device.

Purchased due to having a night time cough made worse by opening the window at night. The unit is neat and easy to operate.Mode 1 - Auto mode which cycles between a very low fan speed which increases if the unit senses a rise in particulates in the surrounding air.Mode 2 - Night time mode, lowest fan setting for minimal noiseMode 3 - Fan speed 1Mode 4 - Fan speed 2 - max, much louder but clears the air much more quicklyThe sensor light moves between blue (cleanest) to green, to white and finally redIt is has a default setting for particulate sensing that can be altered in addition to the light on the unit can be mostly dimmed at night for minimum light intrusion.The unit has 3 filters - a dust filter (easy to clean), a carbon filter and a hepa filter (both are recommenced to be replaced every year or less depending upon the environment it is being used in.Having used the unit for a week I have found the air in our bedroom feels much fresher and even on fan speed 1 with the lights dimmed at night it is not intrusive.Generally very pleased but will be interested to see how it performs come the spring and hay fever season.

I love this air purifier.First, it does its job very well! It purifies the air so well that I get excited when I enter my room cause of the air quality. My place was dusty and had some paint smell, and I felt like I couldn't sleep well because of that. But after having this purifier, I no longer smell pungent and my sleep quality increased.Second, I really like this design. The color matches well with my white wall. Also, since it's rectangular shape, I can put it away in between furniture when i don't use it. Sometimes i intentionally leave it there cause it's kind like a nice looking object in my room.Third, super silent. It's very, very quiet. Somtimes I forget to turn it off cause it's sooo quiet that I don't even notice my purifier is working.100% recommend purchasing it.

My home is quite modern, so it was hard to find an Air Purifier that didn't stick out too much. But this is easily one of the nicest looking air purifiers you'll find. It's a nice size so fits nicely next to a side table in the living room, or bedside table at night.We have a large dog who sheds a lot, so it was important to us that it be able to cope with fur and dander without clogging up, needing constant filter replacements, or breaking easily and it has definitely stood up to the test in the 6 months since we got it.In that time, we've not had to change the filter, but give the pre-filter the occasional vacuum as general maintenance. Even if you didn't, the design of the unit means that the dust shouldn't gather visibly on the exterior. Though if you're forgetful, it also has a small LED to let you know when the pre-filter and actual filter need to be changed. It also has a light to indicate the current air quality, which can be turned off at night if it would keep you awake.Since getting this we've noticed that the air on the floor it is on feels much cleaner, doesn't have any bad smells (not even wet dog after a bath), and there's less dust in the air and collecting on surfaces.For operation modes, there's auto, silent, 1, and 2. We normally keep it on 1 in most rooms, but will put it on auto in the bedroom as it'll typically idle at silent but occasionally bump up to 1 if needed.My only negative is the auto mode. It's probably perfect for most people but I do occasionally wish I could set auto mode to not use silent. It is based on the current air quality, but I'd personally like it if I could have it idle at 1 and kick up to 2 if needed.A side note for anybody looking for a smart air purifier: While this one isn't smart, it nicely remembers its settings when you disconnect the power, so can be used with a smart plug if you need. If it is on when you turn the plug off, when you turn it back on it'll start back right where it left off. Bonus!

It great Purifier, with a solid build, and the filters look good quality. Blends well in the room if you have white walls. Minimalistic design, if that's what you want. Super quiet in the room, we have one in the bedroom and one in the lounge, super quiet and it seems to do a pretty good job for a bungalow of 100+ sqm, can tell the difference. Makes the air fresh and removes any smells. I think will be a great asset in the winter just to get air moving in the house. Time will tell but so far it is great. Highly recommend (bought 2 already)
