Winix - D480 (Refurbished)

Hey all, here's my quick list of requirements that I want * 650 sq ft with 9-10ft ceilings * US * Looking to buy **two** units, preferably under $300-$350 each * No ionizer or UV-C * Not Coway (unless 3rd party filters?) * General filtration. Germs, allergies, etc So I've looking through all the threads and here's my trouble. I don't want ANY ionizer, even if it can be turned off, since the ratings for the unit are done with the ionizer on, and it's a hassle to turn it off every time you turn the unit on (or void the warranty by permanently disabling it). So this rules out Winix or Blueair I also don't want Coway because of their patented filters that have an anti-microbial coating that contains pesticides. Probably won't kill me, but I'd rather skip it. I could use a 3rd party filter in a Coway unit, but then I don't know how well it actually works? I'm looking at the [Honeywell HPA5300](https://www.honeywellstore.com/store/products/honeywell-insight-hepa-air-purifier-hpa5300b.htm) \- but the replacements filters are spendy and the unit is kind of bulky and ugly. So I'm looking for alternatives, but if I can't find any I'll likely go with this unit. Any recs I'm missing? Update - I ended up purchasing two Winix D480 which do NOT have an ionizer and are made exclusively for HomeDepot. The Windmill was another option, but the filters were more expensive and I liked the track record Winix has. Thanks everyone!

Agreed! My main concern with Winix is I'm not sure how well they work *without* the ionizer on, since that's not tested and published.

I have two of the [Winix D480](https://www.homedepot.com/pep/Winix-D480True-HEPA-3-Stage-Air-Purifier-AHAM-Verified-for-480-sq-ft-1022-0221-02/315963577?mtc=SEM-CM-CML-GGL-D29A-029_030_AIR_QUALITY-NA-Multi-NA-DSA-5163653-NA-NA-NA-NBR-NA-NA-NA-MinorAppl&cm_mmc=SEM-CM-CML-GGL-D29A-029_030_AIR_QUALITY-NA-Multi-NA-DSA-5163653-NA-NA-NA-NBR-NA-NA-NA-MinorAppl-20950472636-157401717546-1719180871335&gclsrc=aw.ds&gad_source=1&gad_campaignid=20950472636&gbraid=0AAAAADq61Uf8-WpkyBKFk4Svj20RkSB01&gclid=EAIaIQobChMI5J3mmZXLkgMVPydECB2_khuZEAAYAiAAEgJ0M_D_BwE) and love them! It can only be purchased at HomeDepot. ALL of the other Winix models have an ionizer which can produce ozone, which you'll probably want to avoid. The D480 which is a HomeDepot exclusive is the only one without an ionizer. Coway is also a popular brand but their filters contain pesticides. So I chose to avoid them as well. Honestly, really happy with my Winix and it's in your budget!

It's been great so far! A bit smaller than I anticipated. Also the charcoal filter is not honeycomb, rather a thin sheet like the others (comes with 3 replacements). I much prefer the Winix D480. Much bigger filters, better charcoal filter, no ozone, just plug and play. If you need a purifier overnight like I did, the Mooka is just fine, but if you can wait 5-7 days for shipping, the Winix D480 is the better deal hands down.

My fiancée has bad allergies in all the rooms but our bedroom We have the [winix 480](https://www.winixamerica.com/product/d480-refurbished-3-stage-true-hepa-air-purifier/?utm_source=Google%20Shopping&utm_campaign=Google%20Shopping%20Product%20Feed&utm_medium=cpc&utm_term=183191&gad_source=1&gclid=EAIaIQobChMI87bSpLeZjAMV1YRaBR2llBOfEAQYAiABEgKG9_D_BwE) The link is a refurbished model which honestly is all you need. We bought ours from Home Depot for double that cost

Winix D480. I just bought a refurbished one from them for $110 which is a steal. Idk how well it works for odors as I got mine for dust, but it works great.

It makes sense for air purifiers for the same reason it makes sense for face masks- you want the air to be purified in one go. The misconception that some people have is that air purifiers are supposed to reduce the concentration of particulate matter in the room and hence the highest CFM takes priority. In reality, the actual goal is to reduce the concentration of particulate matter that people breathe in, which sounds similar but has a different meaning. A non-HEPA purifier may theoretically succeed at the former, but it won't succeed at the latter; the mechanism of purifying the air through multiple passes with a weaker filter intrinsically means that particulate matter will be blown across the room and into the breathing space of someone before it can be purified. This why CDC/WHO and many other public health will generally recommend HEPA purifiers and suggest non-HEPA purifiers as a temporary measure for emergencies (I.e forest fires). Some good HEPA filter options are Winix, Smart Air, and Jafanda.

Winix D360/D480 explicitly don’t have an ionizer and work well, I have similar standards as yours and it works well for me. You can get 2 D360s for 300 dollars which would be a bit below 5 ACH or get a D360 and a D480 for 360 bucks which would be above 5 ACH.

In very grateful for my air purifier. I grabbed the Winix D480True HEPA 3- Stage last year and it has helped us so much during these bad air quality days, and in general. It was like $200 but definitely a solid purchase. Would recommend. I live in an old drafty 1910s build and before having a good purifier the high aqi would make my throat hurt even indoors. ETA: we have a dog and rub ours all the time. It helps a lot with per hair and dust. Also if someone sprays perfume or sunscreen or lights a candle the light changes and it filters it out but reminds me that there are so many toxins we breathe daily even without the aqi like this

Alen and Winix are definitely better brands, your best bet to mitigate dust storms is to get a air purifier that just runs, same speed 24/7. Oversize everything so you can run at lower speeds, all air purifiers are rated at their highest speed which is also their loudest speed. I happened to notice the Winix D480 is currently on sale and is a great no frills just runs air purifier.

I have the D480 and have been pleasantly surprised by it. Thought it would have made the list

I suffer from pretty bad allergic rhinitis and sinusitis, even post surgery with 2x/day saline and steroid flushes, due to exposures overseas on multiple deployments. Service connected at 0% each, thank you VA... For \~$150, the Winix D480 from Homie Depot is a life saver! https://www.homedepot.com/p/Winix-D480True-HEPA-3-Stage-Air-Purifier-AHAM-Verified-for-480-sq-ft-1022-0221-02/315963577 At \~350CFM through the carbon and HEPA on "turbo" it will filter all the air in a 580FT² 4x/HR. I have one on each floor as well as one in the bedroom that I carry with me when I'm going to be in the office/livingroom/workout room/etc for an extended period. No wifi connection or even bluetooth app nonsense. Does have an auto function where it monitors air quality and ramps up fan speed as needed. Also has a light/noise sensor to go into sleep mode at low speed, so long as air quality is good, at night and is whisper quiet. Carbon filters are changed quarterly and the HEPA annually. Comes in a \~$55 pack (https://www.homedepot.com/p/Winix-Genuine-D4-Replacement-Filter-for-D480-1712-0100-02/315963579) Am going to invest in a Reme Halo, [https://rgf.com/product-category/air/residential#view\_all\_products\_res](https://rgf.com/product-category/air/residential#view_all_products_res), next spring after I do some duct and HVAC work as well.

Yeah sorry if that seemed overly snarky but basically - although most people have stuff in their air, it’s not clear that everyone needs an air purifier. The first question I always ask is what problem you’re trying to solve - if the answer is (as it sounds like) “well I must have stuff in my air”, then I advise you to get a very basic unit and run it in your bedroom with the door closed to see if you notice a meaningful difference. At the $100 price point you could get a Levoit Core 300, of course we tend to recommend jumping up to $150 and getting a Coway Mighty or Winix. But without knowing your actual air composition or any health issues or concerns, all we can do is recommend a general purpose unit. And honestly it may or may not even be necessary.

1. You don’t really want an app. It is t useful in any way. Why? Because the sensor on the unit isn’t accurate, so the app won’t really tell you if your air is clean. Also because the only way to clean air is to run the unit on a constant speed 24/7. So unless your use case is very specific (vacation home, away for long periods, etc.) then an app isn’t helpful. 2. Shark is junk. Levoit cleans air just fine but is not HEPA, if that matters. Blue air is the best of the three, also isn’t HEPA but has a static generator which bothers some people. 3. Consider winix or Coway. They’re better in every way.

They work just fine. Best of the best. The bipolar ionizer in the winix doesn’t skew their numbers.

Where do you live? No US doctor would have recommended ANY of those brands. Dyson is junk and those others are cheap. Coway, Winix, maybe Levoit. Go that way.

Winix isn’t noisy but some people report them getting off kilter after a while. I’d go with Coway specifically.
