HR900/HR950/HR1000 Series

The c545 doesn’t have an ESP in it. The guide I followed has you add the ESP. Looks like there are quite a few supported models. Winix C610, AM90, HR1000, C909, T800, 5510, and 9800. https://github.com/iprak/winix https://github.com/mill1000/esphome-winix-c545?tab=readme-ov-file

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.

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.

Sharing some info. that I put in another post in the hopes that it’s helpful. Agree that air purifiers are vital. A Winix HEPA air purifier in each room will reduce dander and odor. This is an excellent brand. Vacuum daily. Highly recommend a robot vacuum/mop that self empties. It will make your life so much easier. In this event, you can do one big vacuum once a week. Reading reviews and researching here on Reddit is important to make sure you get the robot vac/mop that’s perfect for your needs. Uproot makes a fantastic pet hair cleaning rake for rugs and carpet. It comes in different sizes and goes much deeper than a vacuum. It pairs well with vacuuming so you can make sure that pet hair is not staying deep in fibers. Recommend Seventh Generation Fragrance Free Disinfecting Cleaner with Hydrogen Peroxide. It deodorizes and disinfects with hydrogen peroxide, as opposed to bleach, which is better for your pups. As others have noted, an enzyme treatment is key for dealing with pet odor and stains. You can use it for accidents and also clean with it to remove odors. For spot treating, spray the enzyme treatment on surfaces and allow to dwell for a period of time - at least an hour and let it stay wet. Reapply, if needed, or cover areas with plastic or damp towels in the case of carpet or rugs. After this period, blot excess, and do not rinse. For maintenance cleaning when you want to remove odor, clean first with a regular spray cleaner and rinse. Follow by spraying the enzyme cleaner and letting it dwell, then blot excess. Don’t rinse. You can use this anywhere in your home, including baseboards, floors, cabinets, bathroom, etc. BioKleen Pet Bac Out Stain & Odor Remover, and Ecostrong Pet Stain & Odor Eliminator are both excellent products. You can purchase both on Amazon. Recommend purchasing an inexpensive black light flashlight on Amazon. You will be able to find any places with urine, vomit and any other biohazard to treat them. For odor and laundry, suggest using a detergent that contains the enzyme lipase. Most liquid detergents in the US have removed it because of cost. It removes human and animal oils. Recommend Tide Clean & Gentle Powder, which contains a complete enzyme, package and oxygen bleach, a.k.a. what makes up OxiClean. It makes a big difference when getting dog items thoroughly washed. Powders tend to be more efficient and this is unscented, which is better for your pup. It’s a marvelous detergent and a favorite in the laundry sub. If you want to keep your current detergent, but it doesn’t contain complete enzymes, add Biz Stain & Odor Eliminator Powder (not Biz Liquid). It contains a complete enzyme package and oxygen bleach. It’s highly effective product. Available at Walmart. Uproot, which makes the cleaning rake mentioned above, also makes what I feel to be the best washing machine cleaner on the market, as it specifically formulated for pet hair. It has citric acid and a complete enzyme round up. Recommend doing this every two weeks on a self clean cycle to remove dog odor and hair buildup.. As well, recommend running a bleach cycle at least once a month. A cup of bleach on the self clean cycle, followed by a rinse cycle so a follow up load doesn’t become stained from the bleach residue. Recommend Chom Chom Lint Roller, which is reusable and excellent for pet hair. It’s become indispensable. Zep Wall Cleaner and Zep Grout Cleaner are brilliant products for when you need to do deep cleaning. Would recommend the pets not be in the home when you’re using these products as they’re strong. You could have them outside or in another area of the house where they can’t smell the odor and be sure you’re ventilating the areas properly. Keeping air vents, fans, and air conditioners regularly clean will also help. They collect much dust hair and dander. Pet Parents Brand has waterproof washable rugs that are good size to put on your bed or on furniture. Washable furniture covers are also helpful. Please avoid plug-ins, and other products like this that just mask odors and are terrible for pets.

Recommend Kids ‘N’ Pets enzyme cleaner. It’s one of the best out there and I’ve tried most all of them. You can clean with a disinfectant cleaner first such as Lysol Disinfectant Cleaner, then thoroughly rinse, or the enzymes won’t be able to work. Then apply the enzyme cleaner, which you can do to any surface in your home, including carpet, let it dwell for up to an hour, and then rinse thoroughly. You can use it in a shampooer. It will make such a significant difference. You can use it on hardwood, baseboards, walls, etc. Because of cat hair, recommend thoroughly cleaning, air conditioners, vents, ceiling fans, hood vent, bathroom fans, etc. They will hold onto hair and thusly odor. Air purifiers in all rooms with the cats will significantly help odor and air quality. Winnix and Conway are both great brands. You might clean out your garbage disposal, using a garbage disposal cleaner. This should help with the odor, and if you have a dishwasher, clean out the inside first, and then run the longest cycle with a dish dishwashing cleaning tablet. You can also periodically pour the enzyme cleaner down your drains, which will help with odor. One of the best detergents to use with pets is Tide Clean & Gentle Powder as it has a complete enzyme package, including protease and lipase. Lipase is key for animal and human oils. Lipase has been removed from many liquid detergents, including all Tide and Persil liquids. It also contains color-safe oxygen bleach, a.k.a. what makes up Oxiclean. If you don’t want to go the Tide route, Whole Foods 365 Powder has the same enzymes and oxygen bleach powder and is unscented, as well. The laundry sub shares helpful information about this. Recommend a thorough clean of your washer, if you have one, via this [method](https://www.reddit.com/r/laundry/s/75UxN3mbt5), followed by running a cup of chlorine bleach, a.k.a. Clorox, on the self clean cycle, or if you don’t have the setting, the hottest, longest cycle on your machine. If it’s a front loader, scrub out the gasket, it’s it’s a top loader, scrub out the inside of the agitator. Clean out the detergent tray.

Thirding air purifiers! I finally gave in and traded my two big winix HEPA guys for a gigantic corsi rosenthal box made of four 20x20x4-in home AC filters. It's much louder but the performance is out of this world, and the filters last forever now. My two 1,200sq ft rated filters struggled in my 500sq ft space with even monthly changes (desert life, lots of animals, massive grading project nearby, endless dust), but this one box handles it no problem, and for many months now.

Both of my Winix air purifiers started smelling like smoke, they are different models, cleaned weekly and filters changed regularly, I don’t recommend them.

you can't beat the physics. what you want is the big size as prioirty thing to look for first. then you can look into other things but the size of purifier(filter) has biggest impact. winix is solid imo for basiaclly 99% of the use case.

I have the Winix. No issues to date. I don’t use the plasma wave feature.

We mainly use the winnix ones. They are fantastic.

Definitely recommend Winix. Australian and comes out top of various tests. (If you haven’t been warned- don’t buy Dyson) Super sensitive to more than just particulates and has a ‘pet filter’ that is changed monthly that goes around the main filter and prevents it getting clogged with dust. Helps to prolong its life if you have pets
