Why not replace the main air circulation filter with a HEPA filter? E.g., I have two filters on my AC/heating system that I replace every month or so even though they're still pretty clean. I'm tempted to simply put HEPA filters in instead. Any problems?

Or I could jury-rig it so that only half of the filter was HEPA and the other half MERV. That would still cut down tremendously on finer particles.

Was wondering if I’d see this model mentioned. I’ve bought four of these, given one away. One in living room, bedroom, one is boxed for an office I’m setting up. Couple notes on this: It is the iPod of air conditioners in its UX and look. The lights on the top are too bright and can’t be dimmed, we cover them in the bedroom with a taped piece of heavyweight paper. The filters do need to be either clean or replaced on…

If you have a new model, hold the ionizer button for 5 seconds and the indicator light will turn off.

Hey I didn’t know that! One of mine has that, but it still doesn’t turn off the green fan speed or ion status lights. I cover those up normally.

I can't tell if they missed the joke about losing 10 fingers and having to stop there, or if you missed their joke that you can insert the same finger multiple times as long as you only lose a bit of a finger each time.

All the above forgot toes

Those are not fingers (at least not in English).

I've never claimed that it does not filter, just that it is a fraction as effective as the alternative at 5x the price. We heat with wood in the winter and some smoke escapes when you open the door to tend the fire. My $100 unit filters the living room back down to the baseline in ~15 min.

Can you let me know the unit you have please?

There are definitely better units out there, but not for $100. That was the sale price at Costco when I got mine.

I still cannot get over this product. They whole selling point of a dyson fan is the 'air multiplier' tech, which creates a low pressure zone that propels air through the ring. According to dyson, this tech can move 15x more air than the fan in the base of the unit. Why in the world would you build an air filter around a system that does not directly interact with 93% of the air it moves? https://www.jameco.com/Jamec…

The fan also sucks compared to something like a Vornado. "Buffeting" of air is not a practical issue when using a fan - you want a fan that can create a lot of air flow. The Dyson fan comes across form first then making up reasons to explain the form retroactively. It feels like an interesting look is the goal rather than something that's actually better. Am I wrong about this? Do people that have the fan like it? Is…

These are some fair critiques. I like the form of the Dyson + Heat I have (not an air filter), but more importantly, I like that it's constantly drawing in air and sampling the temperature much more accurately than a typical space heater which is basically just hoping the bi-metallic strip eventually flips the thermo off. The Dyson seems to do a really good job of holding a fairly consistent temperature, plus it looks cool.

But I got my refurbed on Woot for like, $100, not the $450 brand new they wanted, which is lunacy.

Interesting since the cordless vacuum (dyson v11) I use at home seem to work really well. The previous big corded model we had (Dyson DC33) was also built like a tank and served for almost 10 years before being passed on and still works so maybe I bought into marketing or maybe just different people have different experiences with Dyson products?

Yea, it's weird reading this thread to me. I have a cordless Dyson vacuum and it is by far the best home vacuum I have ever used, both in terms of suction power (even compared to non-cordless ones) and in terms of other usability/features.

I actually hate my Dyson vacuum (animal 8 I think, or something like that). To me it's absurd that it has a trigger - very inconvenient when carrying it around, and tiresome to use for extended time. Made me think that Dysons are form over function, so the linked article plays well into my bias.

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…

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…

They released a new version that fits the form factor of traditional dryers where you only put your hands under it without having to dangle them between 2 pieces. They work pretty well although they do make the table/floor wet since they are blowing the water off your hands rather than evaporating it.

I always found the traditional hot air ones to be useless and I would walk away with wet hands after using one.

Some of the best air filtering systems (and also among the most expensive) are systems like the IQAir [1], which are essentially boxes with a fan at one end and a series of filters arranged in an alternating diagonal pattern: Note: / and \ are each separate filters Filter box ___ | \ | Inflow --> / --> Outflow | \ | | / | ‾‾‾ This maximizes the filtration while reducing the static pressure, since the filtration is di…

How do you think their standalone purifiers, like the IQAir Health Pro Plus, compare to the smaller Blueair Blue Pure 211+? The article measured a CADR on the Blue Pure of 325cfm, while some hits on Google show a CADR rating of 300 cfm for the IQAir one. I'm mainly interested in filtering pet hair, allergens, viruses and SLA 3D printing smells.

It's important to not just consider the "max" number but what it's like while doing that.

I have one of the BlueAirs (forget the exact model number, it's fairly large but not the largest). On any setting other than low (but espeically on high), it's quite noisy.

Like, not just "I can hear this", but "I wouldn't want to carry on a conversation within 10ft of it".

I was of a similar attitude to you until I tried and failed to get a decent cordless vacuum cleaner that has a proper wall holster (i.e. putting it in/out of the holster also plugs/unplugs the charger) I went through several other brands (both well known and no-name things from china) and then returning them to amazon because they were either just crap at cleaning, and/or the wall holster was a glorified hook that re…

I have found dyson to simply be reliable. Yes it might not be the best value for money but when you buy a dyson product you will almost never be disappointed.

Mine run 24/7 on low for a few years so far, one is going on 3 years and the other is about 8 months. No issues other than periodic cleaning and filter replacement. Main hint: keep a spare filter before California fire season.

I've actually been running mine on "2" the ("medium") setting for 3-4 years with no problems. I have asthma, allergies, and pets so.... yeah. Medium it is for me.

I check my indoor air quality and I only have to raise them to medium/high when air quality is bad outside (winter temperature inversions, summer fire season) or when cooking (often don't bother but I'm not as sensitive)
