I live in a large loft-style apartment on two floors which is actually a large room. There are only a few windows and they are placed in a way that no air draft gets created.
When I bought a purifier, one of the things I was looking for was air movement. I position my Dyson so that there's a draft throughout the apartment.
I thought this would improve the air filtration because the air would move through my home and eventually reach my purifier.
My previous experience with a purifier was a Honeywell tower that didn't move air. I noticed an improvement when I switched to a unit that moves air better.
Am I wrong? Should I give up Dyson anyway and choose another product?
- ortusdux 6y agoMy issue is the cost. My local costco has these units in store for $800 USD. Further down the isle they have oscillating tower fans for $30, and smart air filters for $100. I bought two pairs of each before winter. The fans are quiet, have plenty of control options, and non-volatle memory so you can use them with smart plugs. The air purifiers are 4 stage, with active charcoal and a long life (6 mo, 20$) hepa filter. They are wifi enabled, monitor and log air quality, and controllable from a phone. The purifiers should filter my bedroom's air once every 10 minutes, and ~15 min for my living room. This was all under 300$. Edit: to answer your question, the regular dyson fans are great. They quietly and efficiently move air. Pointing one at a real air filter should really help the filter do its job. My issue is that dyson built a small filter into their fans and doubled the price.
- hoytschermerhrn 6y agoDyson, like Apple, doesn’t make products for nerds like us who are willing to go through that level of effort. Their prices are high because their products are simple and “just work” without much fiddling.
- TeMPOraL 6y agoWhat's being questioned here is whether this product actually works (as air filter, as advertised).
- NullPrefix 6y agoSold for a high price and andertised as a working solution is equivalent to a working product, in the mind of a normie.
- Karawebnetwork 6y agoWhile it may not be the best, it still does the job. My partner smokes indoor when I am not present and there's no smoke odor when I get home. According to the chart on their app, the peak low air quality from several cigarettes goes away within an hour or so. https://imgur.com/a/0qgwT1F https://imgur.com/a/0qgwT1F
- ortusdux 6y agoI'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.
- IgorPartola 6y agoI recently got into building DIY air quality sensors. Any kind of smoke hangs around in a room for many hours well past when you can smell it. My house periodically spikes in air pollutants (still looking for the cause but we are moving soon anyways). The one night when PM2.5 spike from safe levels of below 12 ug/m^3 to over 1000 for one night was the worst sleep everyone in our house got. It seems that it was the equivalent of smoking something like 44 cigarettes in a day. Don’t smoke, especially indoors. It’s a bad time.
- driverdan 6y agoThey charge high prices because of marketing. Suckers are willing to pay more than their products are worth because marketing has them convinced it's better.
- pmontra 6y agoSerendipity happens: I was looking at a number of videos about DIY Dyson fans after I learned that bladeless fans exist. Then this post on HN. Examples https://youtu.be/vyJ4wA-3dnY https://youtu.be/vyJ4wA-3dnY https://youtu.be/sFRXkH2XjsU https://youtu.be/sFRXkH2XjsU
- ortusdux 6y agoThey 3d print well if you have a good printer. I've seen designs that use standard size computer fans, which make them cheap and easy.
- throwaway180118 6y agoI wonder if the porous surface of 3D printed materials affects the airflow
- Normal_gaussian 6y agoYou can coat them - and should, otherwise dust gets lodged in and its a PITA.
- joncrane 6y agoWhy 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.
- Karawebnetwork 6y agoThe 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 filters for my Dyson. That way, it would continue to work as a space heater and fan but the air purifying would be done by a dedicated device. Makes sense as by rule of thumb, no "jack of all trades" devices will ever be better than a dedicated device. Hindsight is 20/20.
- timthorn 6y agoThe Unix philosophy of air handling.
- ortusdux 6y agoIt sounds like you need a ceiling fan. I have an ADU with a half loft and 26' ceiling over the other half. One decent fan really moves the air.
- koolba 6y agoCeiling fans are awesome. Especially when you operate them in reverse in the winter.
- Karawebnetwork 6y agoSadly the second floor is a low and angled ceiling. We had installed a ceiling fan with an adapted mount but it wasn't long before one of us hit the fan while removing a shirt. This sent the fan spinning at a weird angle and it hit the ceiling. This broke the wooden blades and sent them flying in all directions. So floor fan it is now.
- noodlenotes 6y agoIt sounds like you're using the Dyson as a fan and something else as the actual purifier. Sounds like that setup works great for you, but it does prove the point that the Dyson is a fan, not a purifier.
- Karawebnetwork 6y agoMy previous experience was with a Honeywell tower but I do not have the device in my apartment anymore. What I am describing is that the Dyson ends up doing a better job alone than the Honeywell did. Especially when it comes to the second floor. However, as you said one could quite likely achieve the same result with any air purifier and a strong fan.
- winkeltripel 6y agoThe answer is always a boxfan taped to whatever filter you want to use.
- hinkley 6y agoVornado used to make an air filter that fires straight upward, but they discontinued it in favor of a design with proprietary filter media. Air filtration shouldn't be this expensive.
