We have four in our house and they are workhorses. Still running strong and quiet 3-4 years later of running 24/7. Probably one of the best things I've ever bought. They are also popular enough, and have been around long enough, that there is an "ecosystem" of third party replacement filters that are affordable and capable. The sound of the Coway is also quite nice for sleeping in our opinion. It's a quiet "whoooosh"…

What benefits do you feel from having four filters? Not hating, genuinely curious. It's just never occurred to me to filter the air in my home aside from burning something on the stove or similar

It depends greatly on your climate. I didn't need one in the midwest, where air quality is pretty good and there's a lot of humidity in the air, but when I moved westward I definitely noticed the difference in air quality (my asthmatic symptoms came back which I haven't had since I was a child).

Especially in autumn when the wildfires start up - even if it's many miles away there is a very noticeable degradation in air quality.

Why wouldn't you just use a cheap fan in place of the Dyson? Sounds like you have a separate purifier that does the cleaning, and all you need is something that will move air.

The only fans I can find that are big enough to move air over two floors make more noise on their low setting than the Dyson's on its high setting. Then there's the issue that the fans would need to be connected to an app in order to power automatically as air quality drops. (I don't have the Honeywell anymore as it was my ex's) This conversation makes me want to buy a second purifier and simply stop purchasing filte…

The Unix philosophy of air handling.

From what I can tell getting a good air purify is all about how much air the thing is actually able to move through the filter, which is primary a combination of filter size and the design of the fan itself. At its core, an air purifier is a remarkably simple product. The biggest mistake people make when buying these things is getting something that cannot exchange enough air to keep the room it is in clean. Manufactures contribute to this problem by overstating the square footage their units can cover.

With respect to Dyson, I think that their cordless stick vacuums are pretty good, and you can sometimes find good deals on them that can make them not too expensive. They have decent suction that probably compares okay to many low-end corded vacuums, and the battery life is reasonable. If you have only a small area to vacuum, and it is mostly hard floors, the Dyson cordless vacs are a reasonable purchase. Just don't expect them to compare to a decent corded vac in the same price range in terms of power.

The recommended pick from the Wirecutter is the Coway AP-1512HH Mighty (as of this post, the recommendation was last updated January 15, 2021) [0]. The CADR is available on Coway's product page in what I assume to be imperial units given the units of the other specifications: "233 (Smoke), 246 (Dust), 240 (Pollen)" (under "Specification") [1]. This CADR score puts it just between the BlueAir Blue Pure 211 and GermGua…

Some additional info about this device is available from Energy Star to confirm the CADR ratings are in cfm. [0] This is odd, as the standard for CADR is often in m3/h. That works out to about 420 ish m3/h in this case. I rememeber seeing a video on YouTube indicating this device takes 2.2W on low, 4.4 on medium, and about 40 on high. [1] The disparity is reasonable, as the fan laws state that power increases with th…

> [0] This is odd,

I suspect by "odd" here you just mean "american". US consumers really don't like having to convert units.

I think Dyson benefits from the same effect as Apple/Tesla/Beats/etc. Their products are good but their triumph is upselling. Dyson cordless vacuums are like $800+, was your previous one that expensive?

My dyson cordless vaccum (v7) was 399$ (CAD) so it was not insanely expensive and I would not go back. Their tech can probably be imitated at a lower cost, but I won't take chances with the cheaper knockoffs, the tradeoff is not worth it.

Their tech probably can't be imitated at the moment because they've got it patented up the wazoo. Luckily patents have a sane lifetime and once they expire I'd expect many competitors to show up with similar designs at lower price points and possibly better engineering.

Dyson : Air Products :: Beats : Audio Products Pretty much every Dyson product I've used, from the public bathroom air "blades" to the vacuums, seem like a gimmicky, inferior products with a premium price tag. None of them do their intended job better than older, cheaper products in their category. I know James Dyson is regarded as a genius engineer, but the consumer product company bearing his name seems to be 99% m…

Their handheld household vacuums are so nice. We have one on each floor. So light, powerful and always ready.

The public bathroom air blades drive me crazy. It keeps splashing the water back and forth, the air speed is too high and my hands inadvertently touch the sides and probably there are a bunch of germs circulating inside, as not everyone washes their hands thoroughly. The old school super blowers that just do hot air down, or whichever direction you turn, probably consume more power, but certainly dry my hands faster…

I prefer the Excel XLERATOR hand dryers, and usually spec them over most other models. Hands dry in ~10 seconds, not spashing onto a lower surface, etc.

I thought those were considered to be a bad idea because they blasted all of the germs from your hands all over the room?

Also, my kids won't use them because they're too loud.

I currently use dyson v11 cordless vaccum. I am in the market for a new one, what do you recommend instead ? Price is not too much of concern for me ATM.

I really like my Miele canister vacuum. It's light, quiet, and powerful. I find bagless vacuums, including Dyson's, to be a pain in the butt to clean by comparison. However Miele is certainly not a good value brand either. I've never used a cordless vacuum, but I find the concept suspect for basic physics reasons. You're either giving up weight, power, or both compared to something you can plug into a wall.

Is there a vacuum that doesn't have a battery but uses the same form factor? I don't mind plugging it in but I don't want to drag around another object I just want to use it like a swiffer.

I hate them because they are too loud. Sure they work fast, but I need to put air plugs in before using them, and those are never provided.

The noise is a feature. It is a social signal that you are clean for everyone in the establishment, or at least for everyone who can see the entrance to the restroom.

I have used a Miele bagged cannister and a Dyson bagless cannister, both corded, and a variety of cheaper units. Miele all the way.
