Is the air quality in your small space less than ideal? Have you become aware of the impact of poor air on your health? If the answer is yes, it is definitely time to invest in a device such as an air purifier, and this article is the resource you just need!

I have prepared a list of the 5 best air purifiers you can buy for small spaces, which are efficient, energy efficient, easy to maintain, and affordable. Suggested air purifiers are suitable for rooms of up/around 200 sq. ft., which is in the standard dimensions of small rooms.

When looking for an air purifier for specific room sizes, you have to look at its CADR. All these air purifiers are suitable for small rooms, and they are AHAM verified, which guarantees they have 4.8 ACH in the suggested room sizes.

Not all air purifiers are a good option for small rooms. To save you time and make your decision easier, I have compared performance, noise levels, operating costs, coverage, and affordability and selected only air purifiers that satisfy all these parameters.

Below, I have compiled the 5 best air purifiers for small spaces, briefly explaining their main features and test results.

It is important to note that I have thoroughly tested these air purifiers and published in-depth reviews with all the necessary information you need to know about each of them. So, if you want to research deeper, I recommend reading these air purifiers’ standalone reviews on the Air Purifier First website.

Levoit Core 300S – Top Choice for Small Spaces

The best air purifier for small rooms is undoubtedly the Levoit Core 300S. It’s a successor of the legendary Core 300 model and offers some great additions and improvements over it.

The Core 300S is ideal for rooms of up to 219 sq. ft., which is a bit larger than the size of an average small room (which is about 200 sq. ft.). It uses a three-stage filtration technology consisting of a pre-filter, a True HEPA filter, and an activated carbon filter.

This air purifier uses a high-quality True HEPA filter that will capture 99.97% of airborne particles as small as 0.3 microns, effectively removing all the common particles in your home, such as dust, pollen, smoke, viruses, etc.

Among its advanced features are an air quality sensor, air quality indicator, auto mode, and smart app compatibility. Furthermore, it delivered outstanding results in our performance tests, operates quietly, and consumes minimal power.

Overall, the Levoit Core 300S is the best air purifier for small rooms you can buy. However, it also showed outstandingly in slightly larger rooms, which is why I would recommend it for even larger rooms of 219 sq. ft.

Blueair 411 Auto – Also a Great Option

Blueair 411 Auto is a minimalistic air purifier with a simple design, a few interesting features, and impressive performance. This air purifier is intended for rooms of up to 190 sq. ft., making it ideal for small rooms such as bedrooms, offices, kids’ rooms, etc.

It uses a four-stage filtration technology with an addition of HEPASilent technology, which is simply an ionizer that can’t be turned off. The first filtration stage is a washable pre-filter, which is easy to clean and maintain. The second filtration stage is a particle filter, while the last filtration stage is a fibrous carbon filter.

This air purifier doesn’t have many advanced options, but it has an air quality sensor, air quality indicator, and auto mode, which, in my opinion, are more than enough for an air purifier in this price range.

During performance tests, it excelled, improving the air quality by about 94% in just 60 minutes in a 194 sq. ft. room. It also did great in a slightly larger room, which makes it a great choice for even larger rooms than recommended.

All in all, the Blueair 411 Auto is a fantastic air purifier and my absolute recommendation for small rooms up to 200 sq. ft. It’s a stylish, affordable, and highly efficient device.

Levoit Core 200S – Ideal for Small Bedrooms

Here’s another air purifier from Levoit that has earned its place on the list. The Core 200S is a small air purifier with a coverage of 183 sq. ft., 3-in-1 filtration technology, and several exciting features. 

The first filtration technology on this air purifier is a pre-filter, the second is the True HEPA filter, and the last one is a pellet-based carbon filter. The Core 200S filter is cylindrical, hollow through the middle, and placed inside the bottom part of the device.

The Core 200S lacks advanced options such as an air quality sensor, auto mode, or similar, but it can be connected with the VeSync app and can be voice-controlled. It is also very quiet, especially in sleep mode, producing a sound of just 42.1 dBA.

In summary, the Levoit Core 200S is a compact air purifier that, thanks to its night light and ultra-quiet sleep mode, is my top recommendation for small bedrooms. While it can be used in any other small room, I primarily recommend it for bedroom use.

IKEA FÖRNUFTIG – Best Budget Option

The IKEA FÖRNUFTIG is a groundbreaking air purifier, primarily because it marks IKEA’s entry into the air purifier market, offering one of the most affordable options available.

The IKEA FÖRNUFTIG is a stylish air purifier, minimalistic, with no advanced options, but with pretty okay filtration technology. Initially, it uses a two-stage filtration technology consisting of a pre-filter and a HEPA filter. However, there is a space for an activated carbon filter, which unfortunately needs to be purchased separately.

Additionally, this air purifier boasts a 19W motor and a room coverage of 108 sq. ft., making it ideal for very small rooms. In my tests, it performed well in a 120 sq. ft. room, improving air quality by 91% in just 60 minutes. Furthermore, it is an incredibly quiet air purifier, ranking among the quietest I have tested so far.

In conclusion, I would recommend the IKEA FÖRNUFTIG to anyone on a tight budget seeking a decent air purifier capable of significantly improving air quality.

Medify MA-15 – Featuring Double Filtration

The Medify MA-15 has earned a place on the list of the best small-room air purifiers, mainly due to its unique double filtration technology. It uses dual 3-in-1 filters, which is the main reason for its outstanding performance in tests.

Although this air purifier doesn’t offer an air quality sensor or similar advanced features, it does provide essential functions such as a timer, display lock, dimmer, and filter reset indicator.

It performed well in performance tests, especially in a test in a 194 sq. ft. room, in which it improved the air quality by about 92% in just 60 minutes working at the max speed.

What I don’t like about the MA-15 is the slightly higher maintenance costs, which are way above all the other air purifiers on the list. 

However, its dual filtration system not only makes it easier to place this air purifier in a small room but also contributes to its performance, which is why I included the Medify MA-15 air purifier on the list.
