Coway - Airmega Jet

I have the Coway Storm and Jet. Can’t really hear them on medium speed, slight noise on high.

I mean what an amazing reply - this is why I post on Reddit. Yes im in the UK sorry about not mentioning that! Im totally sold - will get the coway mega air jet 🥰 Thank you so much for your detailed response and recommendations!

Up front: air purifiers aren't very good for visible dust. It's relatively large and heavy compared to something like PM2.5. Therefore it tends to fall and settle on surfaces unless very close to the intake. That being said, you will capture more dust if you "oversize" the purifier. And if you have pollen allergies, we also recommend oversizing. Coway is generally one of the best consumer-grade brands. The [Coway Airmega Jet](https://en.coway.com/products/airmega-jet-1) would be great, but on my end I can't seem to find replacement filters easily. They're currently sold out on Coway's UK website and Amazon UK doesn't seem to have them either. Uses 50 W on the highest setting and CADR is 402 m³/h. The next best choice might be the [Coway Airmega Mighty](https://en.coway.com/products/airmega-mighty-1). It uses a bit more energy at 82 W (as listed under Performance & Controls) on the highest setting and CADR is 421 m³/h. Keep in mind the Mighty uses an ionizer which can be switched on or off. We recommend keeping the ionizer off if you have pet birds or small animals. CADR may decrease if the ionizer is turned off, but it shouldn't be a significant drop.

I would recommend the [Coway Airmega Jet](https://en.coway.com/products/airmega-jet-1). It's more energy efficient (50 W) and may be a bit quieter (top sound level: 50 dB) than the Airmega Mighty. Keep in mind the CADRs listed for purifiers apply to the highest airflow speed/setting only. Lower settings have lower CADRs, which reduces cleaning effectiveness. There's a little bubble in the bottom left corner of the product page offering 5% off if you sign up for Coway's e-mails.

I had to look through your profile for clues - I'm guessing you're in the UK? Shark is low quality. They're dishonest in their marketing (e.g., "NeverChange" filters schtick is bogus). We've seen numerous problems with the air quality display not working. And if a model is discontinued, filter availability afterwards can be pretty short. I assume by "dust", you're allergic to dust mite allergens? If you haven't already, you'll probably need to take multiple approaches to controlling dust mites. This includes washing bedding in hot water every week, using allergen covers on mattresses & pillows, wet-dusting with quality microfiber cloths, and keeping relative humidity (RH) below 50% for prolonged periods. Dust mites can't survive in low humidity environments. With significant allergies, I'd use a bagged vacuum with a HEPA exhaust filter such as Miele or Sebo. Bagless vacs are often leaky. Obviously an air purifier will only help with airborne allergens and not the ones settled on various surfaces. **For rooms measured in meters, I would seek out a Clean Air Delivery Rate (CADR) 6 times greater than the room's volume. So** ***if*** **your ceiling height is 2.4 meters, this means your room's volume is 60 m****^(3)****. 60 m****^(3)****/h × 6 = 360 m****^(3)****/h. You need a CADR of at least 360 m****^(3)****/h.** Coway is one of the highest quality consumer-grade brands. And yes, they're more expensive. However, Coway units tend to be more energy efficient and quieter than others. A recommended model would be the [Coway Airmega Jet](https://en.coway.com/products/airmega-jet-1). Top CADR is 402 m^(3)/h. The [replacement filter is £59.99 directly from Coway](https://en.coway.com/products/airmega-jet-filters?variant=40840000077917) (GreenHEPA + activated carbon). Filter set is a bit cheaper on Amazon currently. If you were to go with Levoit, I'd buy *two* [Levoit Vital 100S](https://www.amazon.co.uk/Purifiers-Bedroom-Washable-Quality-Allergens/dp/B0CLY1ZG1F/?th=1) units. This is because top CADR is only 243 m^(3)/h. Important: keep in mind the CADRs listed for these purifiers applies to the highest airflow/speed setting only. Lower settings have lower CADRs, which reduces cleaning effectiveness.

No, Dyson is one of the worst! The HP09 has terrible Clean Air Delivery Rates (CADRs). They just know how to market effectively. As **Rule 4** and the AutoModerator comment repeats, it's helpful to know the ceiling height. I'll assume it's 2.4 meters. 60 m^(2) x 2.4 = 144 m^(3). For rooms measured in meters, CADR should be at least 3 times a room's volume (in m^(3)). So the minimum CADR should be 432 m^(3)/h. If you have [allergies, health conditions, high pollution, etc.](https://www.reddit.com/r/AirPurifiers/wiki/index/how_to_choose_an_air_purifier_for_particulates/#wiki_when_higher_than_normal_cadrs_may_be_needed), multiply the room's volume by 4-6. So CADRs of 576 - 864 m^(3)/h. Coway is a high quality brand that's relatively quiet. I don't know exactly where you are, so I don't know what's available to you. But the [Coway Airmega 400](https://www.amazon.co.uk/purifier-restaurant-certified-HyperCaptive-filtration/dp/B099S9Y285) would be a very good fit (Amazon UK website linked). If you can't find that, the Coway Airmega 300 might suffice... although you may want to supplement it with a smaller Coway model like the Coway Airmega Jet.

I’ve been using Nature’s Miracle for spot spraying. I’ve been debating pouring it in with cleaner for the eufy robot vacuum we have.  It helps a bit with the smell when coupled with candles and a big Coway airmega air filter.  I’ve found the biggest help is just getting fresh air in, but that will be an issue with winter soon.

Buy the Coway air mega it usually goes on sale pretty often. 10/10

If I’d known about Austin Air when I bought my Coway Air Mega and Blue Air, I would’ve definitely picked Austin Air and I may still get one. It’s pricey, but so are Coway and Blue Air when you add up the cumulative price of filters. And, I find I need filter replacements much more often than recommended further increasing the cost.

Coway has a better reputation than the models Costco carries. Love our Air Mega. Bought directly from Coway at a steep discount. Just have to wait for sales.

Thirding this one!! Our are great

I like this one too. It’s easier to maintain than corsi rosenthal boxes and is less noisy.

For what its worth, NY Times Wirecutter blog tested a bunch and ranked the Coway Air Mega as the best option. I bought one and am happy with it. https://www.nytimes.com/wirecutter/reviews/best-air-purifier/
