IKEA - UPPÅTVIND

Not much. Easiest explanation is this. So HEPA filters are tighter. Which ofc means that it catches more particles in one go, but EPA12 filters, because they are looser than HEPA, can pass more air through its filters. So for the same given power output, you are cleaning more air - and in each pass, EPA can also catch almost the same stuff that HEPA catches, but at lesser amounts (but it gets more passes of air for the same power output). There's quite a lot of discussion between HEPA and non-HEPA filters in this sub itself if you are interested in a more thorough reading, but the essense is, unless you are building a hospital style clean room, HEPA is probably overkill anyways. I own multiple units of the Uppatvind that I keep in multiple small rooms. They work great for small rooms, bringing the AQI way down. I also have one Starkvind for my living room since its bigger and it does the job. I don't have the table version though but its essentially the same thing - so if you want an airpurifier but anyways also want like a side table, then its a good idea. So if you are buying an Ikea air purifier, I'd either recommend the small uppatvind or the big starkvind and I'd recommend staying away from their mid size variant fornuftig. That one is in my opinion way too loud at the highest setting for what its worth.

If you want it cheap and still good the basic model from IKEA does its job for smaller rooms. UPPÅTVIND costs 30 Euro and the filter for it 5 euro. Much cheaper you can’t gets filters and it’s standard and works fine for PM2,5 for me.

I have nom smart purifiers from IKEA (FÖRNUFTIG and UPPÅTVIND) connected to a smart power outlet. Works pretty well and losing the power doesn't lose the selected speed.

The IKEA filters seem to do the job for me. I similarly am allergic to spring. In early spring I now replace my furnace filter with a MERV 13 and setup and turn on the 2 FÖRNUFTIG in my 2 larger rooms and the smaller UPPÅTVIND in 3 bedrooms and my office. They are very reasonably priced and better the filters are cheap.

My office is pretty small, about 8m² that's why I just use a small unit from IKEA (Uppatvind). It only has a particle filter but with the basic materials I couldn't really measure VOC emissions so I think that's fine. It's probably one of the cheapest filters on the market and it reduces the particle measurements I do to zero or almost zero after about half an hour. So if you have a small room this might be an option. Purifiers for bigger rooms or with VOC filters added usually are pretty pricey I think.

Im on a tight budget and im also canadian (lol) so things are a lil pricey over here. Coway 160 seems to be in my price range just need for my bedroom. Is that a good model? How does it compare to the big boys? Edit: i bought the ikea uptavind and not really happy with the results

Yes, but none of them will deal with the issues in the way you might assume. They work on scrubbing the air over the course of an hour (air changes/hr), they don’t just make ‘smells’ (VOC’s and particulates) disappear. You can make the system more efficient by connecting all of the exhaust’s in parallel and connecting the resulting main exhaust manifold directly to an air scrubber (smoke box) so that 100% of the exhaust is forced through the carbon and HEPA filter sections before returning to the room. There’s a ‘smoke box’ model available on MakerWorld that uses the 30 bucks IKEA Uppatvind for exactly this purpose. The model adds one (or more) activated carbon filter modules to the stock HEPA module along with a 100mm (4” in neo-fascist units) inlet port to draw printer exhaust through the filter. That’s reasonably effective, the replacement HEPA filters are cheap as chips and the activated carbon section can be loose filled or foam type, again cheap as chips. Other room air scrubbers using proprietary filter modules can cost 100 to 300 bucks, with replacement proprietary filter modules being 50 to 150 bucks, which will need replaced every 2 to 6 months! Here’s the fella I’m referring to: https://makerworld.com/en/models/1450535-h2-smoke-purifier-air-purifier-uppatvind That’ll let you know quickly and cheaply what to expect. WRT the H2D, also print the additional internal filter model (it fits in above the chamber filter in the empty space directly in front of the exhaust fan in the H Series) and fire the VOXELPLA ’VENTO’ external scrubber too. You can get it direct from VOXELPLA or print it via MakerWorld and only buy the filter elements from VOXELPLA. Finally, remember that only the IKEA ‘smoke box’ will have any affect on the H2D when printing PLA or PETG as the stock filters are bypassed for these materials in the H Series. The small negative chamber pressure created by the Uppatvind will ensure these are drawn through the filter sections for those materials too. Note: this does require removal of the ‘VENTO’ first, to allow for fitting of the BL smoke hood cowl to the H2D exhaust. Hope that helps a little and doesn’t just depress you? You can try a room scrubber, but my personal experience is that it clears the ‘smell’ within and hour or so of printing finishing and does reduce the odour slightly during printing, but not to the extent that I would want to be in the same room. I only print trickier filaments on my H2S and the small spare bedroom (3.5m x 3.5m) has a small closet, so I ended up putting it in there with the IKEA mod AND a room sized air scrubber in there with it to deal with the ABS/ASA stench. That reduced it to a barely noticeable smell (the smell being a reasonable analogue for VOC and particulate pollution).

if you ever feel like making your own air filter, check our r/crboxes for some inspiration. I have an coway airmega, a 6 fan cr box from NorthBox, a levoit mini, and one of the tiny ikea air filters. every room gets a different size and type of air filter according to the needs of that room.
