Airmega Jet

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.

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!

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.

A True HEPA H13 filter is non-negotiable, as it traps 99.97% of harmful pollutants like PM2.5, allergens, and viruses. First things first, buy an [AQI reader/monitor](https://amzn.to/4fsfyrx) in case the air purifier is not fitted with one, or you want a comparison. If you prefer something that's not noisy and also economical, you can go for the [Coway Professional Air Purifier](https://amzn.to/47aYClJ). Effective and works as expected. It's also highly not recommended to go cheap when it comes to air purifiers, but if you want to restrict your budget, here you go: [Honeywell Air Purifier for Home & Office](https://amzn.to/40Ytq78) For portable air purifiers, go for [AirTamer A320 Rechargeable Personal Air Purifier](https://amzn.to/3H4EJnz) if you're looking for features.

Filter going from 2019. Machine menu says no need to replace yet .

Cowin . Used only in Delhi winter pollution

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

I have two Conway airmegas (and two blueair and two winx… small house but multiple levels). LOVE the Conway airmegas. Two cats, one dog and two people. I have them mostly at room transitions (near doorways and stairs). The amount of dust and pet hair they pull in is amazing.
