Game-changer for air quality
Iâve been using the Coway Airmega for months now, and itâs made a noticeable difference in air quality. Itâs quiet, efficient, and the filters work well to remove dust, allergens, and odors. The sleek design fits seamlessly into any room, and the smart features like air quality sensors are a nice touch. Overall, itâs a high-performing air purifier thatâs easy to use and definitely worth the investment for better indoor air. The wifi ability makes timing it handy but I generally have it on the entire day on the lowest setting. I have several air quality monitors that show a marked difference with this in action

Absolutely fantastic
I purchased this in July 2022 and itâs been on pretty much continuously 24/7 ever since.My partner has all sorts of allergies and suffers a lot, having to take antihistamines etc especially at night in the summer time. We also have cats and ongoing battle with mould in the house.Since using this product Iâve seen a dramatic improvement in my partners symptoms, so Iâm sure it works! The amount of dust, cat fur and other nasty things that accumulates on the washable pre filter is disgusting! I regularly vacuum the house so itâs surprising the amount that this collects. The pre filter is washable and manufacture recommends cleaning every 2-4 weeks. Easy to do I usually just wipe it off and run it under the tap.It has an indicator to tell you when to replace the odour and hepa filters. The indicator is smart and is based on actual usage as opposed to fixed amount of time.The filters arenât the cheapest, I just paid £40 directly from the manufacturer for a hepa filter and 2 odour filters. Considering this will last me a year thatâs about £0.11 a day which given the benefits of using this is well worth it.. I havenât tried aftermarket filters, I wouldnât this product is very well engineered and I wouldnât trust any cheaper 3rd party filters to be 100% as effective.The air quality sensor is incredibly good and reacts so quickly. I no longer smoke but use vapes, if I take a couple of puffs over the other side of the room it notices immediately and speeds up to filter. Changing bedding it always goes red and speeds up. Opening loft hatch it went red. Thereâs always a reason why and it never does it randomly which is good.Itâs quiet on the lower settings. I run it in auto mode. Itâs a bit noisy when it goes into high speed but it doesnât ever stay there for long as itâs so powerful it quickly clears the contaminants.Itâs a decent size, you need to make sure to leave some space around it to for it to work properly.Quality is great.If there could be one improvement it would be on the air intake cover. Dust sticks there and itâs awkward to clean. I ended up taking it apart which I donât think the manufacture intended. Itâs only a few screws but thereâs a small magnet that fell out without me noticing. This magnet is essential for it to work it tells the machine the cover is on. Now I know itâs there itâs no issue to take apart and clean.

Better than my Dyson Purifier
I donât want to knock Dyson too much as I have 9 of their products. But this completely annihilates Dyson on price, what I feel is the quality of the air and most importantly is how silent it is at night. As you can probably guess I have this in my bedroom and the reason I moved over from Dyson was over four years Iâve had the Dyson product has become very noisy and was making it hard to sleep at night. In addition to this because the model is four years old now the filters from Dyson were really expensive and it was virtually impossible to purchase the filters from the Dyson site so I ended up having to spend about £65 per filter. This one has filters that cost about £20.The only disadvantages are that this does not produce a stream of air to call you down in the summer (but quite honestly the Dyson didnât produce a particularly strong flow of air either). And also there is no app so you can monitor the quality of the air.However the ability to analyse the air is really quite pointless. Itâs nice to have and itâs something I would show my friends but in reality this system is perfect because you just switch it on and forget about it.I have to make it clear that when the air quality does drop and it kicks in to a higher speed level it can be noisy but it does not disturb your sleep and quite frankly it does such a good job of cleaning the air that itâs rare that it kicks in to a high fan rate.I would highly recommend this product and if you do currently have a Dyson which you find noisy I personally felt the cost was justified just to get a good nights sleep plus over the years it will pay for itself with the cost saving from the filters (although it will take a few years to pay it back).

Good value
Bought 2 of these, one for downstairs and one for bedroom as missus has allergies. They seem ok, very simple to use and clean. Silent on the lowest setting but it gets very loud. My only problem are the sensors, both machines suddenly ramp up to max speed for no apparent reason in the middle of the night and this will wake you up, sounds like a tornado on max! Annoying and apart from turning it off completely doesn’t seem to be anyway of stopping it doing this automatically!One side note I have seen comments saying the sensor light is too bright with no way to turn it off. There is, you just have to hold the button for 3 secs 🙂

je merkt het verschil. in de eco en nummer 1 stand is hij erg stil. Op stand 3 maakt het wel lawaai. Ik ben er blij mee.

Ik ging af op de vele recensies en het toestel voldeed aan veel normen waar ik het voor nodig heb maar helaas toch niet wat ik zocht. Ik merkte weinig verschil als het om geuren ging en met de winter vond ik de uitblaas van de verse lucht toch wel fel koud aanvoelen als je bijvoorbeeld in de zetel zat. Ik heb zowel honden als vogels in huis en dat brengt toch wel aardig wat stof met zich mee, ook slaap ik in dezelfde ruimte en merkte geen verschil bij de lucht, nog steeds hoesten en verstopte neus dus hier voldoet dit toestel helaas niet, enkel misschien als hij constant op hoogste stand draait maar dat is dan net iets te lawaaierig. Op zich is het een heel mooi en leuke luchtreiniger die de ruimte siert dus ik denk voor gewoon gebruik dat het idd wel een toptoestel is maar niet voor hier.

Uso questo purificatore in cucina da circa una settimana, devo dire che sono molto soddisfatto: ha una buona sensibilità , rileva subito il cambiamento dell’aria e la purifica in automatico. Lo tengo sempre acceso con la funzione Eco, che non mi accorgo nemmeno che è in casa: è molto silenzioso.

Haben das Gerät im Wohnzimmer/ in der Galerie (>35m2) im Einsatz. Hierfür ist es, in meinen Augen, gut geeignet. Es ist zwar nicht gänzlich lautlos, jedoch in der ersten der 3 Stufen angehm leise (Luftqualitätsanzeige blau im Automatikmodus). Geräusche entstehen nur durch die notwendige Luftbewegung, nicht durch die Mechanik selbst und sind somit auch nicht störend. Zwei Levoit Core 300 (S) hatten demgegenüber vernehmbare Lagergeräusche, welche aufgrund ihrer Charakteristik wirklich nerven.Die 2. Stufe ist klar hörbar, aber ebenfalls nicht störend/ tonal unangenehm (Luftqualitätsanzeige lila) Diese Stufe wird, zumindest bei uns im Automatikmodus, nur eher selten genutzt. Stufe 3 ist demgegenüber nun sehr laut, jedoch geht dies auch mit einer âorkanartigenâ Luftbewegung einher, die die Leistungsfähigkeit des Geräts eindrücklich unter Beweis stellt (Luftqualitätsanzeige rot). Das Gerät läuft bei uns im Eco-Automatikmodus, d.h. sofern die Luftqualität ca. 30 min gut ist, schaltet sich der Lüfter aus und läuft erst wieder an, wenn sich die Luftqualität verschlechtert. Funktioniert bei uns bestens und erspart bislang die Einbindung ins Smarthome. Ãberraschend ist der Energieverbrauch des Geräts, Stufe 1 benötigt ca. 3.5W, Stufe 2 um die 7 bis 8 W. Das ist schlicht und einfach top und entspricht sogar den Angaben des Herstellers – was man so nicht immer erwartet. Die bereits erwähnten Levoit sind hiervon meilenweit entfernt, den Core 300 in unserer Küche habe ich mit 15W in Stufe 1 gemessen – bei geringerer Wirksamkeit.Der Vollständigkeit halber: Stufe 3 des Conway zieht bei uns ca. 77 bis 80W, diese Stufe will man aber lautstärke- und zugluftbedingt nicht wirklich länger als unbedingt nötig laufen lassen. Im Automatikmodus läuft diese Stufe bei sehr uns selten, jedoch jetzt im Winter verstärkt nach dem Lüften, da es hier tatsächlich noch Kohleverfeuerer im Viertel gibt oder die üblichen Hinterhaus-Gemütlichkeitsfanatiker, die allabendlich ihre Feuerschale abfackeln und damit nachweisbar zum luftverpestenden Feinstaubemittenten mutieren. Der Brandgeruch wird dann durch Stufe 3 auch recht zügig aus der Raumluft getilgt.Interessant ggf. für die Nutzung an einer schaltbaren Steckdose (hier:Ledvance/ Osram über Hue): Das Gerät âmerktâ sich offensichtlich den Betriebszustand und läuft nach dem Einschalten der Steckdose wieder an. Lässt sich damit also auch ohne herstellereigene App ins Smarthome einbinden – der Levoit Core 300 kann das z.B. ärgerlicherweise nicht, wahrscheinlich um das appgesteuerte S-Modell des 300 verkaufen zu können.In Summe ist der Conway ein empfehlenswerter Luftreiniger der bei uns unauffällig seinen Dienst verrichtet.
