iKea fornufti Features

With the Ikea FÖRNUFTIG air purifier, less is more. This minimal model offers only one control knob and an indicator to reset the filter, yet it still packs a functional punch with its smart plug connection capability.

For those seeking sleek simplicity without distracting buttons, this no-frills design provides just what you need for clean air in your home or office space – not any extra features that can cloud your judgment.

Filter Reset Indicator

iKea fornuftig

The Ikea FÖRNUFTIG includes a filter reset indicator positioned at the top, near the control wheel that notifies you when it’s necessary to replace your filter. Generally, this timeframe falls within 4-6 months.

Wall mounting

Wall mounting is a great way to create an aesthetic look in any room, especially with the Ikea FÖRNUFTIG that can instantly lend it a modern vibe. I recently tested this out for myself when installing the Aura Air air purifier on my wall – easy and efficient!

Smart Plug

To reiterate, the FÖRNUFTIG employs one wheel to regulate fan speed – its only control system. This mechanical component can be connected to a smart plug, making it partially “smart” despite its simplicity.


It’s almost unfathomable that Ikea doesn’t provide any assurance for their FÖRNUFTIG air purifier. When attempting to contact the company’s customer service, you may find yourself stuck in a rut due to their lack of publicly accessible email and real human chat support; even Facebook chat is disabled!

iKea fornufti Design and Size

The Ikea FÖRNUFTIG air purifier adds a stylish, modern touch to any space with its sleek white and black color options. Its front cover is always grey for an elegant look no matter the choice of colors.

Ikea’s build quality is top-notch; the plastic construction should be expected for a device of this caliber. Most impressively, Ikea does not give off the impression of being an inexpensive air purifier.

The Ikea FÖRNUFTIG provides added convenience by offering feet that can be easily attached from beneath the device, allowing it to rest on any hard surface. Plus, if you’d rather mount your device onto a wall for extra security and stability, no problem! The necessary mounting holes are already pre-installed at the back of this handy gadget.

The designers of the FÖRNUFTIG have shown remarkable effort – it’s clear that no detail has been overlooked. The carrying handle provides easy portability, while a power cord that is just the right length allows you to place this device in any room without sacrificing convenience.

Control Wheel

At the top of this device, you’ll find both a control wheel and a filter reset indicator. The control wheel is your primary tool for powering the device, as well as changing its fan speed!

Room Coverage 

Ikea FÖRNUFTIG has the power to uplift any room up to 108 sq. ft., with a CFM of 82.4 or 140 m3/h, giving your space an invigorated and stronger airflow – even when paired with its accompanying carbon filter, there’s still no major loss in performance!

Set your control wheel to 0, and with each successive clockwise click, you’ll switch the device to the following velocity. With three full speeds available, you can then shut off the apparatus simply by returning back to its initial state of 0. Plus this mechanical wheel serves as an excellent link between your device and a smart plug for additional simplicity!


As for the Ikea FÖRNUFTIG, it already comes equipped with a prefilter and HEPA filter. However, to get the full capacity of this product I decided to also purchase an additional carbon filter as part of my review process.

By integrating the optional carbon filter, we can recognize the Ikea FÖRNUFTIG as a premium 3-stage filtration air purifier. These filters are cost-effective and have sufficient power to offer total satisfaction to everyday household needs. It must be noted that they’re not washable and require periodic replacement for maximum efficiency.

HEPA filter

Ikea FÖRNUFTIG is the perfect solution to protect your home from impurities with its HEPA 12 filter, which shows amazing results despite not being as efficient as a True HEPA filter. For those looking for even greater protection against smaller particles, an additional upgrade of a True HEPA filter can be yours – included in the same purchase!


The pre-filter acts as a preliminary filtration stage, with its fabric-attached plastic construction designed to capture the bigger debris and dust particles such as hair strands, pet fur, and any other large particulates. Doing so preserves the lifespan of your HEPA filter for longer use

Carbon Filter

An effective yet often overlooked solution for eliminating unwanted odors is the addition of a carbon filter. Though it typically isn’t included with most devices, this piece can be purchased separately and adds an extra layer to your filtration system that neutralizes noxious smells. For those seeking improved air quality indoors, integrating a carbon filter into their strategy may provide just what they need!

iKea fornufti Performance

The Ikea FÖRNUFTIG air purifier may be small in size, but it still packs a punch for rooms up to 108 sq. ft. It doesn’t take advantage of all the latest filtration technology such as True HEPA filters or carbon capture systems – and that’s evident when it comes to gas interception tests –

however, you should not easily underestimate its performance; under certain conditions, this little powerhouse can surprise even the most skeptical critics!

120 sq. ft. Room Test

The Ikea FÖRNUFTIG air purifier impressively demonstrated its efficacy in a 120 sq. ft. room, reducing the air impurities by an impressive 91% within just one hour of operating at maximum speed!

194 sq. ft. Room Test

I evaluated the Ikea FÖRNUFTIG in a space slightly bigger than what is suggested, and it ran on speed 3 for an entire hour. Astonishingly, the air quality improved by almost 90%, thanks to its MERV-12 HEPA filter – I am very satisfied with this result!

iKea fornufti Noise

The Ikea FÖRNUFTIG is equipped with three speeds, allowing me to easily test the audibility of this machine. This makes it a breeze for me to determine its volume output!

To start, I am frustrated that this air purifier doesn’t have a sleep setting. Even with the lowest fan speed, it is still much noisier than other comparable products on the market.

SpeedValue (dBA)Speed 142.2 dBASpeed 249.3 dBASpeed 358.2 dBA

iKea fornufti Power consumption

The Ikea FÖRNUFTIG is a cost-effective air purifier that uses only 19W of power. It’s efficient enough to run 24/7 at speed 3 for just $1.2 per month, making it one of the most affordable options in its price range – even more so than the Blueair 411! With this bargain energy consumption rate, you can enjoy clean and purified air without breaking your wallet.

Not only are electricity costs minimal, but so too is the cost of replacing filters! Even if you opt for a HEPA filter solely rather than one with carbon, maintenance expenses remain incredibly low and you can feel secure that turning off your machine isn’t worth it.
