Airmega Jet

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 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!

If you cook a lot, you're generating a ton of stuff that is likely better vented outside—doubly so if you have a gas stove. No air purifier is going to be better than a box fan in the window of your kitchen blowing out. We've used a variety of fans in our kitchen window for the past decade, and an air purifier we have just outside the kitchen(a Coway Airmega fan that has a smart feature) doesn't have to ramp up much anymore thanks to the volatiles never actually making it out of the kitchen.

bought a coway air mega last yr. no complaints, no smells ever :) tried that box fan nonsense-even after sealing all gaps around frame/filter, still mostly recirculated the air right near it. worked terribly (regular 20 buck lasko box fan)

I bought an Airmega for our bedroom a year ago. My wife says my nighttime snoring has almost completely stopped. We ended up being so happy with it we bought another for the DR/LR.

I use horse bedding pellets from Tractor Supply, I pour them on the bottom of the litter bin and then put a bunch of hay on top. It works pretty good, someone on here said they found something even better but I forget the name. As far as air purifiers? Absolutely. A great air purifier sucks up so much fur - not perfect, but I vacuum mine every day so it’s easy to see the good work it does. It’s a Coway Mega. Works very nicely. If they’re shedding fur is crazy then they may be shedding, brushing will always make things easier but the purifier is great

I love my winix plasma wave. I also have a Conway air mega that’s sized for my bedroom that’s been going strong
