Ikea FÖRNUFTIG Air Purifier – Is it Good Value for Money?

The Ikea FÖRNUFTIG is a small, very affordable, and very stylish air purifier that has been making a lot of noise lately on the market. This tremendous popularity and interest from users are justified, especially because Ikea’s air purifier can be bought almost anywhere in the world.

The trade-off in price is the lack of True HEPA filters, which directly affects the device’s overall performance.

Ikea FÖRNUFTIG - Air Purifier Review

I have noticed that Ikea has released several different models since the FÖRNUFTIG and is very actively entering the air purifier market. This small air purifier is designed for rooms up to 108 sq. ft. It is ideal for a small bedroom, a small living room, or a similar smaller room.

The Ikea FÖRNUFTIG is essentially a beautiful air purifier that is very easy to set up and use.

Like all air purifiers so far, I tested the Ikea FÖRNUFTIG air purifier’s performance to see how loud it is, how much electricity it uses, and whether this air purifier is actually worth buying. Read on to discover the answers to any doubts you may have about this air purifier.

Installation and Setup

Specific preparations must be made before using the Ikea FÖRNUFTIG air purifier for the first time. As the HEPA filter is packaged but already inserted into the device, it must be removed, unpacked, and returned back into the device.

If you buy a carbon filter, it must also be unpacked and inserted into the device below the HEPA filter.

The next step is to set up the stand where the Ikea air purifier is placed. This stand is made up of three metal parts that need to be assembled and inserted into the holes at the bottom of the device.

If you decide to hang the device on the wall, you must first screw the screws into the wall and then attach the FÖRNUFTIG to them. Something similar to when you hang a picture on the wall. But remember that the screws are not supplied with the FÖRNUFTIG. When the appliance is ready to use, plug it in, place it in the desired location and switch it on.

If you decide to hang the FÖRNUFTIG on the wall, Ikea advises you to put the cardboard included in the package between the appliance and the wall.

Design

Ikea FÖRNUFTIG is designed as a simple air purifier with a modern look. This air purifier is available in white and black color; in both versions, the front cover is grey.

Ikea FÖRNUFTIG Air Purifier - Design

The build quality is second to none, the plastic is ok, as it should be for a device of this kind. In fact, the most important thing is that Ikea does not leave the impression of a cheap air purifier. The Ikea FÖRNUFTIG has feet that can be mounted from underneath, and then the device can be placed on any hard surface. Or, if you want to mount the device on a wall, you can do so because the mounting holes are already fitted on the back of the device.

I like that the designers have thought through almost every detail. They put a carrying handle on the top, making it very easy to move the FÖRNUFTIG from one room to another. The power cord is long enough, just enough to place the device almost anywhere you want.

All in all, the Ikea FÖRNUFTIG is a stylish air purifier that exudes minimalism and modernism in its appearance and can easily fit into almost any ambiance.

Control Wheel

On the top side are the control wheel and the filter reset indicator.

The control wheel is the primary means of operating this device with which you switch the device on and change the fan speed.

Ikea FÖRNUFTIG Air Purifier - Control Wheel

The initial state of the control wheel is 0; with each clockwise turn, the mode switches to the next speed, a total of 3 speeds. To switch the device off, the steering wheel must be returned to position 0. This mechanical wheel allows the device to be connected to a smart plug.

Airflow

The Ikea FÖRNUFTIG is a rectangular air purifier with filters located on the device’s front. The FÖRNUFTIG pulls air through the openings on the front, through the prefilter, which is essentially a fabric. The air is then filtered and exits through the openings on the top side of the device.

Size and Dimensions

The air purifier weighs 6.7 lb (3,3 kg). The dimensions of the device are 18.1 x 12.2 x 4.3 inches (46,1 x 31 x 10,9 cm). The Ikea FÖRNUFTIG is not a very large or heavy air purifier, so you can easily move it from one place to other.

What’s in the box?

When you buy the device, you will receive an Ikea FÖRNUFTIG air purifier, HEPA filter, power cord, and user manual. The carbon filter is not included with the Ikea FÖRNUFTIG; it can be purchased separately.

Features

The Ikea FÖRNUFTIG is a minimal air purifier with hardly any advanced features. This model reminds me entirely of the Blueair 211+, which I recently had the opportunity to test and which, like the Ikea, uses only one control knob and an indicator to reset the filter.

In addition to the filter reset indicator, the Ikea also boasts the option to connect to a smart plug, and that’s basically it. So if you’re looking for a minimal air purifier without extra buttons that can only distract you and occupy your attention, then the Ikea FÖRNUFTIG is just the model for you.

Filter Reset Indicator

The Ikea FÖRNUFTIG uses a filter reset indicator located at the top, right next to the control wheel. This handy option lets you know when it’s time to change the filter. This period is usually between 4-6 months.

This way, you won’t have to manually track when you need to change the filter, and you can conveniently rely on the Ikea filter reset indicator.

Smart Plug

As I explained at the beginning of the review, the Ikea FÖRNUFTIG uses one wheel to change fan speed, which is the only control you get with this air purifier. As the control wheel is mechanical, you can attach the FÖRNUFTIG to a smart plug and thus make it at least partly a smart device.

Basically, if you want to attach it to a smart plug, all you have to do is leave the FÖRNUFTIG at the speed you want to use it at and then connect it to the smart plug. After that, you can switch the air purifier on or off from a remote location via the smartphone app.

Wall Mounting

In addition to being equipped with legs for the floor or any other hard surface, the Ikea FÖRNUFTIG can also be wall-mounted. This is a convenient accessory, especially as the Ikea FÖRNUFTIG looks modern and can decorate the wall and the entire room in which it is placed very nicely. I recently tried the Aura Air air purifier, which is also wall-mounted and just as easy to install on the wall as the Ikea.

Ikea advises you to put ready-made cardboard behind the device if you decide to hang it on the wall.

Warranty

It’s a bit unbelievable, but Ikea does not give any guarantee for the FÖRNUFTIG air purifier. I turn to Ikea’s support, which is very difficult to contact, mainly because they have no publicly accessible email, no real human chat support, and disabled Facebook chat.

I managed to get them on Twitter, where I received confirmation that they do not have a warranty for this device. If I needed any help from them within 365 days of purchase, I could contact them.

Room Coverage

The Ikea FÖRNUFTIG is designed for rooms up to 108 sq. ft. with a CFM of only 82.4 or 140 m3/h. It’s important to note that the CFM drops further if you choose to use a carbon filter, but this figure is minimal, and I don’t think it’s worth mentioning, especially when you consider how much efficiency is improved by adding a carbon filter.

This small air purifier best fits a small bedroom, small office, kitchen, or similar room that is about 100 sq. ft. or slightly larger.

Filtration Technology

The Ikea FÖRNUFTIG is equipped with a prefilter and a HEPA filter. In addition, it is possible to purchase a carbon filter. For the purpose of the review, I bought the carbon filter to test the FÖRNUFTIG at total capacity.

Ikea FÖRNUFTIG Air Purifier - Filtration Technology

If we include the optional carbon filter, we can say that the Ikea FÖRNUFTIG is a 3-stage filtration air purifier. The filters are very affordable and efficient enough to meet the needs of ordinary households. They are not washable and require occasional replacement.

I recommend that everyone buys a carbon filter, as this will allow you to use the Ikea FÖRNUFTIG air purifier to its full potential.

Prefilter

The prefilter is the first stage of filtration. It is essentially a plastic construction to which a fabric is attached. The primary purpose of the prefilter is to collect all large dust particles, hair, pet hair, and large particles, thus preserving and extending the life of the HEPA filter.

Ikea FÖRNUFTIG Air Purifier - Pre-filter

The prefilter is not washable but does not need replacement. It is recommended to clean it with a vacuum cleaner at least once every two weeks.

HEPA filter

Ikea FÖRNUFTIG uses a HEPA 12 filter, which is less efficient than the True HEPA filter but has shown excellent performance. A True HEPA filter is more efficient and can stop much finer particles than the HEPA filter in the Ikea air purifier. The HEPA filter is included with the device and is not purchased separately.

Although it is not True HEPA, I am again delighted with the performance that Ikea FÖRNUFTIG has made with this HEPA filter. Perhaps it would not be a bad thing if Ikea left the option to buy a True HEPA filter.

Carbon Filter

The carbon filter is the last stage of filtration and is not included with the device but can be purchased separately. This filter is credited with neutralizing odors. I recommend it to anyone who wants to get rid of odors more effectively than is possible with a HEPA filter alone.

You should note that the CFM drops slightly if you decide to put a carbon filter in the Ikea FÖRNUFTIG, but this is negligible and does not affect the coverage of this device much.

How do I replace my Ikea filters?

The Ikea FÖRNUFTIG uses replaceable filters that need to be changed at a particular time. Fortunately, this air purifier uses a filter reset indicator to let you know when to replace the carbon and HEPA filters. This time is approximately 4-6 months.

The prefilter is not changed; it should be cleaned at least twice a month. The filter replacement process on this air purifier is straightforward.

Noise Test

The Ikea FÖRNUFTIG has three speeds at its disposal to get the job done, which makes it much easier for me to test the volume produced by this model.

Ikea FÖRNUFTIG Air Purifier - Noise Test

To begin with, my complaint is that this air purifier does not have a sleep mode and that at a first speed, although it is very quiet, it is still much louder than some competing devices.

Speed Value (dBA)
Speed 1 42.2 dBA
Speed 2 49.3 dBA
Speed 3 58.2 dBA

It is loud even at maximum speed, but not that much more than the rivals. Personally, I do not mind it working at top speed, as the engine’s sound is pleasant, there is no squeaking or unpleasant noises. Note also that at maximum speed, the machine’s efficiency is highest.

I used the Ikea FÖRNUFTIG for a while in my bedroom, I like that there are no indicators because the extra light is very distracting, but I would have liked the engine sound to be at least a little quieter.

Performance Tests

The Ikea FÖRNUFTIG is a very small air purifier designed for rooms up to 108 sq. ft.

This device has a low airflow and does not use a True HEPA filter, but it works better than I expected. Although I bought a carbon filter for testing, I can say that I am not satisfied with the performance in gas filtration. This model filters gases poorly and needs much more filtration time than some other similar air purifiers. Below I will show you the most exciting tests I have done on this device.

120 sq. ft. Room Test

In the first test, in a 120 sq. ft. room, the Ikea FÖRNUFTIG improved the air quality by 91% in 60 minutes of work at maximum speed.

# Starting Baseline After 60min
PM 2.5 106 9.6
PM 10 148.5 13.4
Particles 153808 13972
AQI 138 13

In this test, the FÖRNUFTIG performed well in a room close to the recommended dimensions. I noticed a slightly lower performance in gas filtration, even though I used a carbon filter.

194 sq. ft. Room Test

I tested the Ikea FÖRNUFTIG in a 194 sq. ft. room, which is slightly larger than the recommended dimensions for this product. The FÖRNUFTIG was running on Speed 3 the whole time. In 60 minutes, it improved the air quality by about 89%, which is an excellent result considering it uses a MERV-12 HEPA filter. I can say that I am pretty satisfied.

# Starting Baseline After 60min
PM 2.5 102.2 10.3
PM 10 143.1 14.4
Particles 148217 14977
AQI 134 15

I should mention that I used a carbon filter in all the tests, which also contributed to the performance of this model. Overall, the Ikea FÖRNUFTIG performed satisfactorily, but not as well as I would expect from a modern air purifier.

Operating Costs

The Ikea FÖRNUFTIG uses very little energy; it is powered by a 19W engine. This small, very inexpensive air purifier, if left running at speed 3, for 24 hours a day, will cost you about $1.2 monthly. This is a minimal cost and a very similar consumption to the Blueair 411, which like the Ikea FÖRNUFTIG, is one of the more affordable air purifiers to maintain.

Ikea FÖRNUFTIG Air Purifier - Operating Costs

In addition to the electricity costs, there is also the filter replacement cost, which is also very affordable. Suppose you choose to use only a HEPA filter without a carbon filter. In that case, the maintenance costs of this device are so minimal that it is not worth switching it off.

Speed Power Usage (W)
Speed 1 1.2W
Speed 2 5.5W
Speed 3 13.2W

The carbon filter is slightly more expensive, but it is a matter of choice. All in all, the Ikea FÖRNUFTIG is one of the cheapest air purifiers to maintain that I have had the opportunity to test so far.

Final Thoughts

Ikea, a well-known brand, has expanded its product range and is slowly taking over the air purifier market. The Ikea FÖRNUFTIG is the model that has caught my attention the most at the moment, and I have received a lot of inquiries from curious followers to review this product. These are some of the reasons why I tried the FÖRNUFTIG air purifier.

The Ikea FÖRNUFTIG is a modern, minimal, and very affordable air purifier that is very quiet and uses very little electricity but also doesn’t have such good performance, which I think is mainly due to the lack of a True HEPA filter and lack of stronger airflow.

Overall, the price-performance ratio is very good, and I recommend the FÖRNUFTIG air purifier to anyone. If you have any questions or concerns, please leave a comment in the comments box below or contact me directly by email.
