IKEA - FÖRNUFTIG

I have 2 of the [Ikea FÖRNUFTIG Air purifers](https://www.ikea.com/us/en/p/foernuftig-air-purifier-white-50461961/) in my 800sqft apartment with the carbon filter and they work great one in my bedroom and one in my living room might be overalkill having two. Bought them originally for having cats, but these past two weeks have really noticed the difference from inside my apartment to the almost immediate allergies and throat itch as I step out my door. Pretty great and compact mounts on the way and blends in well.

The IKEA rectangular one. Seemed cost effective on paper but maybe it’s not the absolute best one out there. https://www.ikea.com/ca/en/p/foernuftig-air-purifier-white-50461961/

Just to conclude, I bought IKEA air purifier with Carbon Filter yesterday. I hope this will be good enough. Thanks

I like it. As with some PLA brands, occasionally my Air quality detector beeps occasionally as they give PM2.5 a bit more for some seconds and with this purifier running at 1st speed (silent completely) don’t let the detector beep anymore.

Yes I noticed for sure

IKEA FÖRNUFTIG. $60. Works. Next question.

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.

I had the IKEA one got rid do it because I didn’t have space for 2. It was in my bedroom. It worked pretty well TBH. My other one is a levoit 400s for comparison.

Get an IKEA FÖRNUFTIG air purifier and the optional “filter for gas cleaning” (it’s a big carbon filter that goes inside). Works great, easy to set up, and relatively quiet depending on the ambient sound in your room. https://www.ikea.com/us/en/p/foernuftig-air-purifier-white-50461961/

According to Wirecutter: ( https://www.nytimes.com/wirecutter/reviews/best-air-purifier/#the-competition ) The IKEA Förnuftig is neither a true-HEPA purifier nor an especially powerful purifier, period. It’s designed to capture PM2.5—particles 2.5 microns in diameter and above, in contrast with the 0.3-micron HEPA standard. That means it’s optimized for larger airborne particles, such as pollen and mold spores, rather than for very fine particulates, like wildfire smoke (as HEPA filters are). We tested the Förnuftig in a 200-square-foot room, focusing on how well it removed 3-micron particles from the air. It disappointed, removing just 85.2% of 3-micron particles in 30 minutes on high and 73.6% in 30 minutes on medium. Its performance on 0.3-micron particles was, as expected, worse: 64.5% removed on high and 53.5% on medium. Compared with other small-space purifiers we’ve tested in the same space, that’s very poor.

The figures don't sound bad compared to waving your hand in front of your face and saying "shew, it's dusty in here!", but it is way worse than everything else they tested. The IKEA machine is way cheaper, so it isn't like you are getting super ripped off if you buy one, but you would need about TEN of them in a small room to remove as much 0.3 micron particles as their top pick, the Coway 1512. Ten! It would be like using Christmas lights in your grow house because you like the way they twinkle. If you don't care about smoke and only care about pollen, then it might make sense, but it is just a whole other category of appliance.

They seem to work really well, too, despite being so much cheaper than other brands. I've got serious hayfever this year, and they've been a lifesaver round the house.

The Fornuftig. Being able to mount it on a wall was the main selling point for me, I don't have many free surfaces in the house.

One thing I will say, just to be aware of. It's very quiet on its lowest setting, you can't hear it at all. But its middle and highest setting are pretty noisy. Its a big leap in dB from low to middle. Not a problem if you have small rooms, where the low setting will suffice with air changes. It's not distractingly noisy, no more than most budget fans, but something to be aware of if sound is important. I think they have dB measurements on the Ikea site.

the ikea one has a great value for the price, and the cheapest of all replacement filters I know off.

Ikea also has the cheaper non-smart  FÖRNUFTIG that you could control with a ZigBee switch. In my room I let it run when the magic area presence state is "extended". When I'm in the room more than 5 mins.
