David Wahl

  • 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 8-10 square metres, depending on which fan speed the air purifier is set to.

    The particle filter is optimized to filter away approximately 99.5 percent of smaller airborne particles such as PM2.5 particles, dust and pollen.

    PM2.5 are small inhalable particles, that measure 0.1-2.5 micrometres.

    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 odour of smoke, cooking odours and other unpleasant odours 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: 120/25 m3/h (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: 3.05 kg (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.

Air PuriferYasminThis is a godsend for my sons room. The price was affordable, compared to others available elsewhere. The streamline design is perfect to mount on a wall.5
Great product but the frontMaureenGreat product but the front cover keeps falling off4
Pleasantly surprisedCharlesWhat drew me to eventually purchasing this was the price as well as the price for replacement filters, both of which are significantly more affordable than even base models on the market. The price is almost deceptive; one would perhaps expect to sacrifice a degree of product quality for the price point however there is little to none and I was pleasantly surprised. Within just 30 minutes of use there was a notable difference in the air quality of the room I have installed it in. I did have a dust problem, and am particularly sensitive to dust, which is what finally motivated my interest in getting an air purifier and this has virtually eliminated that concern. At the lowest setting, unless you are specifically listening for the noise it is barely there if even noticeable. The caveat is that at the highest setting you can definitely hear the fan at work but can not say I am particularly bothered by it as it's almost like a white noise. It could not be simpler to use with only the single knob allowing for three fan speeds and the unit is very light so moving it around say from room to room is not an issue. It comes apart very easily for cleaning or installation of filters, once required. In addition to that, it was easy to mount on my wall with the guide provided which made up part of the packaging box which was a nice touch, and if not mounting the stand works just fine too. I love the design of it, allowing it to be an accentuating stylish feature of the room decor as opposed to appearing as another appliance. As mentioned, the price of the replacement filters is also a huge positive in consideration of this product. I have had it running for most hours of the day since purchasing it. I regret I had not purchased it sooner. I have been enthusiastically recommending this to family members and friends. A great purchase.5
Good for getting rid of smoke from bushfires in a roomDarrylLets us sleep easier at night with clean air in the room. Need to seal up the room and have it on for a 2-3 hours, but it makes a noticible difference to the room4
It was an impulse buy.SharonIt was an impulse buy. I prefer to leave the doors open to outside air. But it does get used occasionally is is relatively quiet.3
Pretty good little filterCharlotteI was living on a main road and it was very dusty. This filtered out a lot of the dust in the room and I also used it with the gas filter while cooking. Though not sure how good the air quality really is compared to HEPA filters but still great value for money. I did notice if I didn’t have it on at night I was more stuffy in the mornings. It’s also great for white noise at night for sleep. This was a second purchase for a second bedroom. Overall a great product5
Allergy SufferersJoannaI have been having a lot of sinus issues while trying to sleep where one side of my nose will completely block to the point I can’t breathe. This causes my mouth to open and then I wake up too often during the night. After a week of using this product I’m getting better sleep each night as I can breathe easier while trying to sleep. While I do have some other sleep issues that need addressing this has helped immensely in the interim.4
Works very well, I’m sureJanetWorks very well, I’m sure it helps me sleep easier5
Reasonably priced Air purifierRossThis is a very good air purifier but the design is very basic with mundane colours. The unit is a bit noisier than what I expected. The high speed setting is noisy and something I find I cannot use if I am in the room.4
Great productMarkGreat product5
Work perfectlyPedramWork perfectly5
Starts out great but...JohnWe purchased two of these units and both were extremely quiet at first. They certainly do work well as air filters but within two months the one we had in the bedroom became too noisy and had to be swapped with the one in the lounge. Since then the other unit has also become noisy. They both have a very irritating rattling sound that I've tracked down to poor quality bearings in the fan motors. Now, less than a year old, we're looking at replacing both units with different, hopefully much higher quality, air filters.1
Nice ,coolEuiI'd like to recommend this product. It's really quite in Night time. So nice and cool item. I love it.5
Incredible value for moneyKtThe desire for a air purifier with a HEPA filter was solved by the Förnuftig. Low speed is so quiet it doesn't interfere with our sleep and higher speeds provide a comfortable air flow. Add a gas filter for bathroom cleaning and removal of unwanted chemical smells.5
On par with $500 air purifiersKatieI am absolutely happy with this product. Decent air purifiers can cost upwards of $500, so if Ikea want to charge me $100 + $20 for an additional filter, I am more than happy to! When I am home, I run it on setting Medium or Low, and turn it up to High when im out of the house! As we have cats, we have noticed a remarkable difference in the air quality. I will be purchasing another one for the bedroom!5

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

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 optimising 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.”

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.”
