"It's still not providing 4-5 air changes an hour to 3,000 square feet ... It's common for air purifier manufacturers to mislead on square footage coverage. The 3,000 square foot is likely based on one air change an hour. That won't be enough for someone wanting a purifier to help with allergies, viral load reduction, dust reduction, etc. ... The Blue Air website recommends 635 square feet for 4 air changes in an hour. ... The 635 square feet assumes the device will be ran on the highest fan speed to achieve the 4 air changes an hour. ... After doing some deeper digging I learned not to trust the advertised square footage. Even some big name publications are just trusting manufacturer claims and are not doing their own testing to verify. Members of this forum like myself try to educate people that we can't always trust the advertised square footage. ... It's unfortunate we can't always trust the advertising. I wish manufacturers would give a straightforward number on air changes you can expect in an hour within a certain square footage and ceiling height. For ex: 4 air changes an hour in 500 square feet 1 air change an hour in 2,000 square feet"


"Energy Star rates the Coway Airmega 100 for 169 square feet. ... Sadly it's very common for air purifier companies to overinflate their room size coverage. ... Energy Star and the Association of Home Appliance Manufacturers are great sources for seeing the recommended room size. Even then, the room size is based on the highest fan speed. Sometimes there can be big differences among the different fan speeds."


"However, it claims to have 3500 sq foot of range but it doesn’t have the best range as I disconnect once I get to my front door. The router is upstairs with nothing directly blocking it."

Hi, I've 4 coway air purifiers at home (2 bkh). 3 cats furry cats, fabric sofas and couple of large carpets. I'm extremely sensitive with dust and I can feel it in my nose and throat even if it's very little dusty. After getting these coway air purifiers I feel sooo much better. I've used Dysons, Mi, blueair. Out of all of them I love the coways. I have a [Coway Airmega 400](https://uae.sharafdg.com/product/coway-airmega-400-air-purifier-ap-2015f/?cpn=21923874463&pl=&kw=&adg=173662259467&ch=g&utm_source=google&utm_medium=cpc&utm_campaign=LS_SharafDG_Std_Shopping_Bilal_18112024&utm_term=&device=m&utm_matchtype=&utm_network=g&utm_placement=&utm_content=721914495737&utm_Adposition=&utm_location=9198260&utm_Sitelink=}&utm_Audience=pla-2455809539967&utm_campaignid=21923874463&utm_adgroupid=173662259467&gad_source=1&gclid=Cj0KCQjwkN--BhDkARIsAD_mnIr3GqdSYguutizgQurZxifbzxMiU0evhunlX8jR6u0HUgUsoYxvx3MaAvuyEALw_wcB) next to my bed. 2099 AED.

All of the conventional options recommended won’t cut it if you’re being serious. I have a few coway airmegas and blueairs and they don’t do much for real VOCs/smoke. You need a lot of carbon for that. My airmega has like 1lb of carbon, I’d recommend an allerair- I’ve got two airmedic 6 pro and the difference is remarkable. I think they have 25+ lbs of carbon. Very simple design, no bells and whistles, but very effective.

When I turn the purifier off, the indoor reading goes back up to match the balcony level. So the purifier is clearly making a big difference.

I got a Coway Airmega because it was highly reviewed on the Wirecutter website after my previous Levoit broke after only a couple years and wasn’t fixable (circuit board inside was fried).

1) Recirculating air purifiers don't need to be medical grade. CADR (Clean Air Delivery Rate) matters more. Example: An EPA E12 air purifier vs a HEPA H13 (True HEPA / medical grade filter) air purifier having the same CADR -> The EPA E12 is better. True HEPA is way too air restrictive and CADR already takes the filter efficiency into the equation which is why CADR > filter efficiency alone as it also accounts for the airflow within the filter. It doesn't mean that True HEPA is bad. It's just gonna usually be more noisy than an E12 for the same performance. More info on this here: [https://www.reddit.com/r/AirPurifiers/comments/1hne7sy/stop\_buying\_true\_hepa\_hepa\_h13\_air\_purifiers/?utm\_source=share&utm\_medium=web3x&utm\_name=web3xcss&utm\_term=1&utm\_content=share\_button](https://www.reddit.com/r/AirPurifiers/comments/1hne7sy/stop_buying_true_hepa_hepa_h13_air_purifiers/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button) 2) Air purifiers are better used in specific rooms. If you have 3 rooms then u need 3 air purifiers, one for each room. I need to know the room size in sqm/sqft and also if u have more than the normal 8ft/2.4-2.5m ceiling height. 3) You should buy a bigger air purifier than you need. The reason is since your family member has a health issue you 100% need the purifier to have AT LEAST the 4.8 ACH (Air Change per Hour), and since you might not want the air purifier to work at max speed all the time, you need to go at least 50% more if not double the power that you need. I generally recommend 50% more than what people need and let it run on low speed but in your case i recommend 2x more than what you need and run it on at least medium speed. 4) Good products that I recommend are either Philips PureProtect Series (3200 / pro 4200) or Coway Airmega 300/300s/400/400s. 5) Not related to air purifiers but look into fasting. Prolonged water fasting for at least 3 days, than refeeding with carnivore diet. Also the stem cell protection that a 3 days fast gives you on doing chemotherapy. There is more to it but here is a starter video : [https://www.youtube.com/watch?v=Wzmacu2TgFg](https://www.youtube.com/watch?v=Wzmacu2TgFg) Cancer works by feeding on the same feeding system as your body which is carbohydrates that you eat. If you switch off a carb rich diet and go carnivore diet you won't have any more external carbs (you ll feel like crap because of low glycogen stores but so will the cancer) so it will slow down the cancer's growth, since the cancer's main food source is your energy source which are the carbs. Moreover autophagy is your body natural system of getting rid of bad cells. It's a hunt for them. In a normal setting your body is just fighting bad cells. In autophagy mode your body hunts the bad cells to eat them as food. Guess what cancer is and what your body will do with it. There are plenty of cancer cases where autophagy helped. Do your research on it. Also your family member needs to have some fat/muscles to be able to do this and the refeeding needs to be aggressive to put back the lost fat and muscle during a fasting period. Salt is also required in the water but you'll learn about all of this if you do proper research. Not a medical advice since I don't know the specifics of your case but please look into it.

We have two Coway Airmega units, one on either side of the house. They have been on 24/7 for several years now. Maintenance and cleaning are very minimal. Cost is about $150-200, although there are larger units based on how big of an area you need to filter. We are very happy with them! Whichever purifier you choose, I highly recommend you look into one with a replaceable HEPA filter. Other filtration methods just won’t give the same results.

Agreed! And they now offer different filters depending on what is most important to you to filter: one for smoke, one for allergens, etc.
