When David had trouble finding affordable and good-looking air purifiers, he started experimenting and building his own at home. “They turned out nice, but were honestly not the most efficient.” The experience was still valuable when he joined our team that developed FÖRNUFTIG air purifier. The work was much about optimizing all small technical details to make it simple without sacrificing quality and energy-efficiency. “But when we develop at IKEA, we also do it from a home furnishing perspective, and we want FÖRNUFTIG to blend into the home. That’s why you can hang it on the wall, put it on the floor or use the handle to move your air purifier to another room.”

Good to know
The air purifier comes with a particle filter so it purifies the air from various particles as efficiently as possible. You can also buy a gas filter and use the two filters together.
Particle filter included. Gas filter sold separately.
Purifies the air in a space of up to 85-105 square feet, depending on which fan speed the air purifier is set to.
The particle filter is optimized to filter away approximately 99.5% of smaller airborne particles such as PM2.5 particles, dust, and pollen.
PM2.5 are small inhalable particles, that measure 0.1-2.5 micrometers.
The gas filter (sold separately) purifies the air from various gaseous pollutants such as formaldehyde, which can be found in things like cleaning/household products and various fabrics and materials.
The gas filter helps to reduce the odor of smoke, cooking odors and other unpleasant odors that may be present in the home.
You can set the air purifier to 3 different fan speeds and thereby adapt it to the needs of your home.
Set the air purifier to sleep mode, the lowest fan speed with low noise, during the night so you can sleep well while the air is purified.
The air purifier has a clean design, a low weight and a small size ⎼ so it’s easy to place in your home.
Practical cable management on the backside helps you avoid cable clutter.
The pull-tag on the right side makes it easy to loosen the pre-filter in order to clean it, or to remove it to change to a particle and/or gas filter.
Suitable in various rooms of the home, even in the smallest children's rooms.
Check the filter regularly to see if it’s dirty. An LED indicator illuminates when you need to check your filters and possibly replace them. The filter is recommended to be replaced within 6 months.
Clean Air Delivery Rate (CADR) at highest/lowest fan speed: 70/11 CFM (with both particle filter and gas filter installed).
Sound level at the highest/lowest fan speed: 60/28 dB (with both particle filter and gas filter installed).
Maximum wattage: 14 W (with both particle filter and gas filter installed).
Net weight: 6.7 lbs. (with both particle filter and gas filter installed).
The particle filter is tested according to EN 1822-1 and ISO 29463-3 which corresponds to class EPA12.

Plug BreaksShelieI purchased one, the plug separated; received a replacement, the same thing has happened. This isn't a part that can be easily replaced so I've very disappointed with this air filter.
Good but the price of filters keeps going upTaraI've had this for over 3 years now and every couple months the price of the filters go up it started at $9 now it's up to $17 for the same filter it's getting ridiculous
Great little air purifierJoshAs with most Ikea things, this thing is cheap, but it works well and I have no complaints. I use this with the gas filter in the room I keep my cats' litter boxes in and it has made a noticeable difference in air quality. I have had mine for almost a year now and have had exactly zero issues. When I replaced the filter for the first time, the white filter was substantially darker than the replacement so I know it really does do its job. I also really like how on the lowest setting, it is just about silent unless you get close to it and really listen for the whir of the fan. Overall a great product for use in smaller spaces.
Amazing Purchase!RichardThis product works really well, especially for the price!
Really nice actuallyMI was worried about buying this because of the reviews but I'm on a budget and decided to take a gamble as these were more affordable. I'm glad I did. I've had it for about a month now and it works great! The lowest setting is so quiet you can hardly hear it, I wasn't sure if it was on at first. The second setting has a steady noise but it's not too loud and is like a soft white noise, so it's not bothersome. I have it right next to my bed and it's not a problem, though I like white noise when I sleep. I bought two of them and will be moving soon so I haven't set the other one up yet but will post a review if anything is different. I would say give it a try. If you like white noise or want something on a budget this is a good option. I had a different, more popular brand air purifier and it had all the same problems in these bad reviews and ended up making an awful, loud noise. It's hit or miss with any product you buy these days.
This has made such a difference in our home LaforestWe think this is great to have. The air quality is excellent.
Didn’t work KrystaPurchased and it never worked had to return. They had a few people try and get it to work and nothing. Ended up getting money back
NoisyLucyLike other reviews have stated, was ultra quiet for the first month of use but now makes a whirring sound, even at the lowest setting. Didn’t keep my receipt so can’t return it. Would not purchase for a bedroom.
great air filter, still going strong RebeccaI have had this little guy chugging along almost continuously for over a year and it really helps with dust, odors and seasonal allergies. It's also very quiet even on high speed.
One of the reasons I purchased this was the price of the filters, and as a bonus, needing to but filters gives me a reason to go to ikea.
Failed in less than a yearMarkLooks nice but after about 6-9 months of usage in a small room the motor is shot (still runs, just extremely loudly, and possibly with less airflow). I have several other air purifiers that have run nonstop for years without problems.
Ikea does many things well but not this one.
Broke after less than a weekIreneLoved it at first, but after about 3 days of use it went kaputt.
Works wellMariagood design, easy to assemble and works well in our living room and office. We have two cats and dog. It really makes a difference.
it works well with my small bedroomAnonymous reviewerI had it for few weeks
so far so good
it will take a six months time to find out how good it performs
No warranty - noisy after 10 monthsWilliamI was happy with this unit until the fan began to show signs of failure and became noisy during use. After speaking with IKEA staff, for this product there is no warranty and no spare parts option - just an expired 6 month return period. This is not a lasting product, based on my experience. Would not buy again.
It works amazingly!MichaelSince the pandemic I have become more intolerant to certain airborne particles within my house. I vacuum religiously every weekend and dust as needed. About 18 months ago I bought one of the förnuftig, placed it next to my bed and turned it on to the lowest setting. I no longer wake up coughing and sneezing. I also noticeably have less dust in my bedroom which made the decision to buy 3 more for the house a no-brainer. Thank you for making a product that has improved the air quality within my house, and saved me cash on replacement filters!
Great alternative to big bulky air purifiersJacobI replaced my old air purifier because the company stopped making the filters for it(AFTER 8 YEARS lol), so I got rid of that big bulky(but great) thing and replaced it with 4 of these foernuftig purifiers; I hung one in the living room, workout room, bedroom, and the kitchen) around 70% high from the floor and let say that they work SO GOOD at cleaning my air! I set them all at medium and my little apartment doesn’t have a SPECK of dust and it’s so easy to breathe now living next to a busy road! I only bought one of the charcoal filters for the kitchen purifier to help with cooking smells and I bought some long charcoal filter media and cut them to size for the other three! Coming up on half a year and I can say these Foernuftigs were well worth the money! I got 2 for 59.99 on sale. If they’d keep these that price all the time I might buy 2 more(1 for the bathroom and one for the master closet to keep lint down)! A side note high is noticeable but not super loud as some say.
Works wellCarolynI bought this purifer to help with odors in my small kitchen ,as there is no exhaust fan. I've had it for a couple of months now, and so far it seems to be doing a good job keeping the air clean. On low setting it is barely audible but a little noisy when on high. I generally keep it on medium as a compromise.
It is an attractive unit and doesn't take up much space sitting on the counter.
Air purifierAshleyGreat for a small room! My child’s allergies have stoped significantly since we’ve been using it
Sleek and space savingMistyWay better than the bigger bulkier purifiers you get elsewhere. Looks chic and can even be wall mounted
Effective, but loudJulieA little on the loud side, but a good price e. Replacement filters are also relatively inexpensive.

Story
Furnish with cleaner air
Pollution in a busy city can often be visible to the naked eye. But, did you know that the air in our homes also contains pollution from dust, pollen, cooking and gas chemicals that are bad for our health? Airing out and cleaning help to a certain degree, but with an air purifier, the particles and gas chemicals such as formaldehyde are effectively filtered – while you do other things.
David Wahl works as a Product Designer at IKEA. In connection with a move some years ago, he became more aware of how much the indoor air means to our health. “All homes contain particles and gas chemicals in different shapes, and today when we spend more time indoor, they can lead to, among other things, allergic reactions and bad sleep.”
An air purifier that blends in
Cleaner air for more people
FÖRNUFTIG is quite far from the first attempts David did at home. In a team with various competencies, there are better preconditions to develop a reliable air purifier that can make a difference for more people. “Air pollution is a serious problem, and we want to provide solutions that help people breathe cleaner indoor air.”
