Winix - C535

First thing I want to say and it's important. The most important thing you need to know is that the air purifier has got to have true HEPA that is not an option ... 3m/filtrete is a joke of a purifier. They are terrible and do not last. biggest problem you have with their air purifiers are they are not sealed purifiers. There is a lot of dust that gets through other places and bypasses the filter in the unit and then what happens is it collects after the output vent so you will eventually start seeing dust there. Another is their filter cost. It's insane. if you look at their filter replacement schedule, it says the filter lasts 12 months used six hours a day.... air purifier are supposed to run 24/7 to have full effect so if you run it 24 seven that’s every three months their filters are also small... but I personally recommend and have used the past is these two for your size room are these I'll link. you get an air purifier that is going to be more powerful in your price range and will last for starters... There’s a reason why you want something with a higher CADR is because it will clean the air more frequently in that room and clean it better. You will get more air changes per hour basically and that’s a good thing. Also, you’re not gonna have dust getting past your filters and leaking out of the top of collecting everywhere else. You will also get a true 12 month filter when you run it 24/7. It comes with a TRUE HEPA and four replacement carbon filters. One of them will even include a additional year of filters if not both of them out of the box. The Coway Airmega is also another amazing air purifier for the price, however the filter costs have you replacing filters every 3 or 4 months with full use. Alen is also expensive from the get go but filters are annual. I have used these Winx purifiers in the past and I love them the plasmawave can be turned on or off I'd it's a concern but it doesn't produce ozone. I am just linking site so you can get all the information on them however I don’t know if you have a Costco membership or they still sell them or not but it was a great place to get these at an even cheaper price. https://www.winixamerica.com/product/c535/?_gl=1*1v4e0th*_up*MQ..&gclid=CjwKCAjwwLO_BhB2EiwAx2e-35mFNXJgc1BeCOGMGegBQ-An_KwmCD6L29mTNy-0yyIBkVrET2C_jhoC034QAvD_BwE https://www.winixamerica.com/product/c545/?_gl=1*u8q5cp*_up*MQ..&gclid=CjwKCAjwwLO_BhB2EiwAx2e-35mFNXJgc1BeCOGMGegBQ-An_KwmCD6L29mTNy-0yyIBkVrET2C_jhoC034QAvD_BwE

So here's what you need to know. Levoit does not HEPA filters. That is a problem. They can't dter as effectively as a HEPA. Next, in order for an air purifier to do its job it should really run 24/7. With that said Coways are amazing but the filters are expensive and need replacement every 3 or 4 months. With your layout if you want to purify the whole home.you need to determine the size of each room and get a purifier for each one. The purifier cannot clean the air in all the rooms or in half the rooms.if you were to have one big one or one for each end of the home, even with doors open. The only way you can achieve that is to have a special whole home purifier installed on you HVAC system which costs a ton of money. Id recommend a Winix per room to achieve what you want. You should measure the sqft per room and determine what size room it should clean. It needs to have atleast 4 air changes per hour. If you are wanting something relatively cheap. I'd stick with Winix, you cannot beat it for the money.

Yes. All of their purifiers use HEPA

I'd go with the winix if that is what you are looking for the 3m is not that great

I use 5500-2's and C535's (costco's 5300-2 made for them) in all rooms, including the bedrooms. I would look at it more as where do you generate the most dust (human dust - aka skin cells). And that'd be the bedroom during sleep hours. I wouldn't go any smaller than the Winix 5500. The CADR / AHAM room size ratings is tested against max fan speed only. Keep that in mind when sizing the filters and the intended speed you're planning to run them at. Match the filter sizes, its easier. Easier when buying on amazon in bulk packs as well.

Thank you for this information. I think the procurement team only approved the Coway AP-1512. you're right that at top speed it'll be too loud at times. I'm thinking of just using a second machine, say a Winix C535 from home, doubling up and running both of medium speed, which would likely give me a total CFM of about 250. I really appreciate your suggestions and efforts on my behalf. They make sense, but they didn't want to spend more money. After doing some research I wanted the AirFanta 3Pro but I don't think they'll go for an unknown. Given how much CFM it moves, even though it's loud at top speed, at about medium speed, it'll still run somewhere in the 300s CFM. Either way, I'll have much more than 67 CFM. The main concern is viruses, COVID, though also the flu and other things. I don't want to get sick for its own sake and for reasons of missing work.

Winix c535 from my local Walmart super center was around $170 out the door and it comes with 2 hepa air filters + 9 carbon filters.

They claim the two filters + carbon filters are good for 2 years total

Winix has helped me tremendously. They are cheap to buy, cheap to maintain, and they work extremely well.

I'd go with the Winix because it has a real HEPA filter and its AHAM certified. Having said that, if the units don't have enough power for the size of your rooms, they won't do much. You can get a much better C545 on Winix Americas website for $130 right now, and if that would put you over budget, refurbished C545s are only $90 (also on Winix America's website). I purchased a few refurbished C535s (the older model) years ago and they served me well.

That's a good one. Just don't rely on auto mode and you may want to buy some blackout stickers to reduce the amount of light coming from those super bright lights.

Credentials : I currently have a Golden and a St. Bernard, before them I had three Great Pyrnees,,,,at the same time. I've also owned 19 vaccuums 😂 I have two Shark robot vaccuums that run on a staggered schedule, constantly. Essentially, they're always "sweeping." I use a silicone broom ,too, and that works way better than I ever expected it to. I also mop with a bissel crosswave every day and swear by it. That takes care of our entire downstairs, which is all LVP flooring.  As for our regular vaccuum, we have a Kenmore Intuition, and I love it for all the carpeted areas. It comes apart just like a Shark- I can do the couch, the stairs, all the nooks and ceannies, etc- except the suction is way better than a Shark (I said what I said.) I don't deal with hair coiling around the brush head all that often so that hasn't been an issue for us.  We also use a silicone broom on all the furniture, in conjunction with a mattress vaccuum, and it works great. We have a Winix air purifier in every single room, I love them. The filters get vaccuumed once a week and we replace them every 6ish months. People always remark that our house doesn't smell like dog, which a huge achievement as a Saint owner lol.  As for the dogs themselves, they get brushed outside every three days, like clockwork. They also get deshedded and groomed regularly at the groomer. Constant brushing and regular grooming really helps with the allergy thing. The bed: duvet covers that get switched out once a week, sheets washed once a week as well. Being a dog owner is just a battlefield of dog hair, the best defense is having a good offense. Between the vaccums, the air purifiers and the grooming, we're doing okay. We may not be winning the war, but by God it feels like we've won some key battles.  Edit for spelling*

I'm on mobile browser so it's hard to link so I'll just tell ya! We have the C535 for all the common areas, and the C610 in all our bedrooms. Then for the bathrooms and pantry we use the LEVOIT Mini Cores (I like these for small areas, but I have to change the filters more frequently.) 

I got a fairly small apartment with 2 bedrooms upstairs and a small basement and I got a Winix T830 in my living room/kitchen area(with my setup basically in-between the 2) a Winix C535 in my kids room a Shark Compact Never change in my room and a Shark Hp100 in the basement. I'd say it's definitely not overkill lol. I've definitely preferred the Winix over Shark

Fwiw after going down a similar rabbit hole to OPs I ended up buying the C535 from the Winix website. I think you can get the filters for that one from Costco but my memory kinda sucks.

Do have the Coway 250 as an option? I got one for $250 open box or refurbished on Amazon. It’s amazing. The sound it makes is very pleasant and it’s easy to clean, and aesthetic. The Coway or 240 is also a good choice and comes in white. The Winix 5500-2 or C535/C545 is also a solid choice and a bit more affordable. I believe Costco has good deals on the C545. Lastly, you could check local marketplaces. I got some Winix, and Blue Air purifiers (the 203 slim, 403, and 503) for a great price.

We bought a Winix. Like it so much that we bought another one. It comes with a set of replacement filters. You can also buy additional ones from Amazon.

One is a C535, the other is a C545.
