I changed ours to a 3rd party filter about a month ago (this model [amazon.com]). Honestly, without an air particle detector, I'd be hard pressed to say there's been any difference in our air. I'm currently weighing whether to spend more than 55% more to get one of the Coway branded filters. Leaning more towards just getting another of the 3rd party.

I'm on my second set of this particular 3rd party model linked here - they are just as good as the OG. No noticeable difference even after being OCD about it for about 4 months. I'm sure there are some crap 3rd party ones but these are top notch.

Some will say '3rd party weighs less' <- I don't think they do. HEPA filters weigh more after 6+ months of use given the particles they collect - it's a noticeable weight difference. Same weight delta for changing 3rd party to 3rd party as it was changing from OG to 3rd party.

All that being said, if you're not convinced of 3rd party, this is a rare deal for OG filters for only 20 or 25 more than the linked bit.

EDIT: I actually went for a S&S for the third party one you linked at 42 USD for next year's refresh.

I've been washing my filers with garden hose every year. And it's been working just fine...
The hose isn't going to get what is needed out of those filters other than large particles. Expect your 2nd year to be about 50% as efficient (this is from research a long time ago, but I don't think hepa filters have changed at all) in filtering air. Not sure if that just equates to drawing more watts or reduced airflow (probably both) - but I'd argue dropping 50 to 75 on 1st party or 3rd party every 12 months is going to cost you less for the lifetime of the product than hitting them with a hose and it'll work as designed and clear the air as rated as opposed to being hobbled and straining the whole kit.

Curious if you noticed a difference when you first bought your Coways? Meaning when I bought mine I immediately noticed a difference the next morning when I woke up... as I have been smoking for a couple of decades. It's been ten months now and for the last few months I have been waking up to congestion more and more. I know I need to change my filters, and would love to save some money, but don't want to go the aftermarket route unless I know for sure they will work as well as the Coways.
Thanks for any more input you can give.

I just went and washed mine out because of the comment. Not a single drop of water made it through. Which tells me not a single molecule of dust was pushed out. Complete waste of time.

I'm kind of in the same boat, while I don't smoke ciggies anymore, I do consume a lot of weed like it or not. So I change my filters more often than normal as smoke will radically shorten the life of the filters. Exactly how much I don't know, but I don't think it's too much of a stretch to assume about 1/2 of the 12 month life for filters on this unit if you smoke.

Having just switched the filters through the entire house (The 400, the smaller conway, and a winix) I do definitely perceive a difference and am less sniffly, but also who TF knows what is going on with the weather as of late, so I'm sure it's wrapped up in the crazy stuff going around after a drought, etc. as much as filter replacement. Beyond filter replacement, I'd consider playing with location, speed, and auto for placement.

As much as I stand by the third party filters the other Slickdealer linked, if you're on the fence for your first switch go for the Conways at this price so you don't second guess the effectiveness of it. The third party ones will stay about 50% less when the next set of OGs give out so you can mark the difference on the switch after you've sussed what a 'proper' replacement looks like. As I mentioned in the other post, this is a great deal for OG filters if you don't believe in 3rd party.

EDIT: If the question was a general 'do you find them effective?' absolutely yes. But that's after some objective thought put into it after doing HEPAs for about 3 years pretty hard - the first year or so I'd shrug if you asked me how much of a difference they make - after rocking them for a while I've just noticed fewer respiratory issues. They're a very fluid sort of product though - you won't get effective use out of them if you're not savvy on how air flows through your joint and space. In general, auto mode aside, you don't need to be running these things if you're not home or in a different section of the house as the area will go back to normal pretty quickly when it isn't actively filtering. A.k.a. if you switch it on an hour before you get home you'll find the same air quality if you had been running it continually for 8 hours, etc. I put a lot of thought if I'm in a room and can close the door, leave it open, or where the doggoes are hanging which makes a big difference in effectiveness IMO. It becomes as second nature as messing with a light switch when I enter a room but YMMV.

Envious of your ability to quit. Gratz on that btw. And right there with ya on the other. I have a weird setup in the house. Upstairs is HVAC'd and have three 200s in the bedrooms. Downstairs has wall unit and a 400 sitting under it. I keep the 200s on 2 and ion turned on and the 400 was on 2. but now the 400 is on 3 and runs like it is on 2. I don't like auto on the 200s because when they ramp up.... I have to turn the tvs up. Then down. etc.
At any rate I think I'll just go with the 3rd party link. Just been scared because you never know if the comments and answers are from Coway people/fans, if they saw one comment online and decided that that must be true so now they spread the lie elsewhere, or if it's just a person that got a HEPA because they were scared of COVID and don't know any better. Meaning they are healthy already and they wouldn't know a difference between Coway and Aftermarket. So I have been hesitant to save the money. You convinced me otherwise. Enough at least to where I'll give it a shot. Thanks.

edit to your edit: Thanks for that info. Makes sense.

The third party filter link is down. Can you post the name of it on Amazon so we can search for it?

As someone that is very wary of buying 3rd party versions of things like this I have to say I started buying these from Filter Monster and have been very happy with them. Indistinguishable from the 1st party ones imo. https://filter-monster.com/products/co-400-fm1

Since you're too busy watching Fox news instead of using your brain, I looked it up for you...

"A plurality of California's federal land (43.5 percent, or over 28.8 million acres) are owned by the U.S. Forest Service...

The state park system consists of 280 parks, beaches, trails, wildlife areas and other public lands. The system comprises approximately 1.59 million acres."

This Wirecutter review tested the same brand Cabiclean filters (using the smaller AP-1512HH). The tests seem to show no noticeable difference from OEM.
