ZERO+ PRO (5-Stage)

Hi OP! An Australian based recommendation that I use is the Winix Pro https://ausclimate.com.au/products/zero-pro-5-stage-air-purifier It has a CADR of 470m3 per hour. Because it is an Australian based company - the filters are relatively affordable to replace and they’ve been around a long time so stable and likely won’t be going out of business anytime soon so worth the upfront investment. Lots of positive reviews so please don’t take my word for it! I have mine in between my bed and my door. Sending lots of solidarity from bed! Good luck

I agree with the above comments. I am extremely chemically sensitive and my condition started in an office where we brought in a lot of IKEA MDF tables. We returned the tables, but my condition remained. I recommend the IQair Multigas if you want the best home machine for removing formaldehyde and VOCs. It’s expensive though. For basic filtration at a much lower cost, I’d go with Winix. We have the pet one and it’s actually amazing at eliminating smells in the kitty litter room. Replacement filters are also not too expensive. To solve the CO2 issue, you have to exchange indoor air for outdoor air. Purifiers don’t remove CO2 and create fresh Oxygen. Trees do and for trees/plants to work sufficiently indoors hid need them almost wall to wall (there are a lot of myths about like you only need one spider plant etc. but you’d actually need to live in a greenhouse of plants). For CO2 you’ll need to open windows or vent. However, when you use a vent, like a bathroom fan, you’ll likely be pulling replacement air from someplace else in the building, not necessarily a better place with fresher air. A fan blowing in pulling fresh outside air in can get a lot font in a short time. Even ten mins can make a big difference. Go search on YouTube for air purifier info. There is a lot of expertise out there. I learned about the IQair/Winix combo from a researcher in Beijing. Using both makes the IQair filters last longer. Also avoid Levoit. They just got caught lying about being hepa in several of their models. They do have good air purifiers, but some are apparently crap. Last note: because all air purifiers are noisy when they are on high, it’s better to get one that’s for a much larger space and run it at a lower, quieter speed. Consider getting two Winix purifiers or 2 of some other kind with some carbon in the filters. Winix is at Costco.

Levoit just got in trouble for lying about having hepa filters in some of their purifiers. This makes Levoit a big no in my estimation. I’d choose Winix. I have 4 IQair multigas units, 1 Winix and 4 tiny BlueAir purifiers. I appreciate that the Winix had no odor right out of the box. My house is big, we have an apartment with fragrant renters and I’m allergic to fragrances so I need the big purifiers.

Just make sure buy a modern model. HEPA filters have evolved a bit over the years and so has the regulation. Old "HEPA" filters might not be true HEPA by today's standards. Just make sure you don't buy one with an ozone generator, or if you do, since many come with it (my Winix with PlasmaWave, for example), remember to deactivate it. They are not very good for people's health and I guess they are far worse for birds For reference, I have a Winix Zero Pro

Air cleaners/purifiers (I have one in every single room, 2 in the open living dining kitchen area). Some brands offer pet specific filters (I use Winix plasma waves in larger rooms, and Levoit for smaller rooms, both the cylindrical and the rectangular). Regular vacuuming. Blankets on furniture that can be put in washing machines. If you have hardwood, minimize your area rugs and mop once a week, if possible. If you need area rugs, try washable rugs you can toss in the washing machine. I have three dogs, a breed that is notoriously difficult to house train. I keep an armada of enzyme cleaners and a black light on hand. They are also a breed that loves blankets, so I use specially formulated enzyme cleaner in the washing machine when I wash their blankets. The washing machine runs daily here.

Just bought a Winix Zero S and really working wonders! It stopped most of my dust-related morning allergy. Would 100% recommend for the price. I know I’m gonna get flamed for this but my Dyson TP09 does an okay job too in my office. Just takes longer to clean the room (and it’s more noisy). At least it clears the high levels of formaldehyde that my office seems to have. (With severe allergies stay away from Dyson though)

My Winix Zero S has made wonders for my stuffy nose. I used to wake up and spend the morning blowing my nose. Now I’ll just do it after waking up and be good for the rest of the day (most of the time). The important thing is you have it running at full speed at least 30m before you enter your bedroom, then you can switch it to lower levels for the night. I have a Dyson TP09 running in my office as well, that might be helping too (this one starts running at full speed 2h prior to my arrival to the office, since it’s a big room with high ceilings).

I have a Dyson tp09 and a Winix Zero S. The Winix destroys the Dyson in every aspect. The only thing the Dyson has over the Winix is the fancy meters and cool app. If you are still gonna go for a Dyson I can sell you mine for cheaper (so that I can go buy more Winix purifiers).

That Coway should not be over the Winix. The carbon filters in it are trash. Also, Dyson combo unit on the list? 🥲

If its just 1 room and youre on a budget you can try the winix zero (s). The zero was less than 100 pounds in the netherlands. No smart. But filters are very affordable compared to other air purifiers + good cadr. It wont help much with smells, but you said you care less about that.

The winix zero will be great. It is for bigger spaces, but that means you dont need to run it on max speed to keep your smaller room clear(less sounds than a smaller one). If there are a lot of VOCs everyday the filters will need replacement more often, but that is the case with every air purifier. There's many off brands that sell cheaper filters because its a popular brand.

UK here, I got a Winix Zero a year or so ago. It has a carbon filter and HEPA filter and it hasn't flagged it needs its filter replaced so far. It has an air quality sensor and you can turn off the "plasmawave" if you wish. Very good, would get one again.
