IMHO the benefit is less “things are cleaner in my house” and more “I’m breathing less PM10” and such
Ah dang, I’m sick of dusting stuff
Since that’s something you care about, I will offer an out of topic advice: robot vacuums (in general: vacuuming a lot) decreases the amount of dusting you end up doing.
Depending on what’s on your shelves, you might find my solution of use. Whenever things are a bit too dusty in my house I put on a filter mask and fire up an electric leaf blower. Blasts all the dust off of the various hard-to-reach surfaces and into the air. Then I either use a high-volume blower fan to circulate the air out of the house through a window (if the weather’s nice) or if it’s winter I just let it settle and vacuum it out of the carpet (some ends up back on the shelves, sure, but most surface area in the house is floor so it’s still a net win).
Some other stuff gets knocked off the shelves in the process, but I just consider that a sign of weakness. Those things didn’t deserve their prominent position on those shelves to begin with.
You are insane and I like that!
Are there dumb robot vacuums? I don’t want to buy a little spy robot that maps my apartment layout to sell to advertisers or whatever.
- Only dust in the air that passes through it
- Only if the filter is maintained
- Surface dust is unaffected
Its a noticeable amount, but not likely all of it
When you say surface dust is unaffected I assume you mean the dust that’s already settled prior to getting a purifier right? If I were to use an air purifier I’d need to dust surfaces less often right?
Air purifier? That’s a less than ideal term since it gets applied to stuff like ionizers that are of dubious efficacy.
But a straight up filter, hell yeah they work. Just check the filter on your furnace/heater sometime. Same with any AC unit.
If you have something that has a filter, it will reduce dust, period. Without a filter, you aren’t going to reduce dust worth a damn, if at all.
But you also need to make sure it’s turning the air over often enough. I haven’t looked the info up in ages, but if you want a decent reduction in particulates, the device has to move air fairly significantly it it isn’t going to about to much.
Like, my house is right around a hundred years old. Four humans, and various animals over the years. Shit is dusty what with the dead skin, particles from things like carpet, pollen, dander, etc. Enough stuff gets produced that even with the regular furnace/ac filter, and a handful of one-room filters spread throughout the house (which tends to be better than one big one imo) we still get dust buildup on everything. But if we don’t run the filters, you can both visibly and nasally tell the difference.
A newer house isn’t going to have as much, so you can likely get away with less air turnover, short term, and need to dust less. But you’ll never be totally dust free just because you can’t move enough air to prevent at least a little settling.
