There’s nothing quite like the aroma of burnt toast in the morning and spicy curry sauce in the evening… We all wish our extractor fans did their magic and removed the smells along with the smoke, but it rarely happens.

If you want to keep cooking smells and unwanted kitchen odors at bay, then you should consider getting an air purifier with a good amount of activated carbon to remove gases and smelly volatile organic compounds (VOCs) from your air.

1. Best kitchen countertop air purifier: Levoit Eleva 300X (with Premium carbon filter)

The Eleva 300X offers excellent air cleaning performance, a responsive laser sensor and 260g of carbon to tackle odors.

Levoit Eleva 300X Kitchen

The Eleva 300X is small enough to fit on top of your kitchen counter, so you can place it near where you cook and it will get to work as soon as smoke and smells are released into the air. With a PM1 CADR of 165 cfm, it can clean the air five times per hour in rooms up to 247 sq. ft. (23 m2).

Unlike most cylindrical air purifiers, the Eleva 300X has separate particle and odor filters. This is good news: you can replace the odor filter once the carbon is full without having to throw away a particle filter that still has life in it.

Levoit Eleva 300X Carbon filter

For the kitchen, I recommend upgrading to the Premium odor filter as it comes with 260 grams of activated carbon pellets. The more carbon you get, the better the air purifier will be at removing unwanted smells from the air.

It has a laser sensor that enables auto mode, so the air purifier can automatically get to work when it senses pollutants in the air. You can see particle and air quality readings on the screen at the top of the device.

Levoit Eleva 300X Controls

You can also connect your Eleva 300X to the VeSync app from Levoit to control the air purifier remotely, track air quality metrics over time, customize the auto mode, schedule routines and set different smart modes.

CONS

You must register the filters to pair them to the device. If you don’t do this, you lose the filter lifespan tracking function.
The use of AI in the data reporting seems to add complexity and lag for no obvious benefit.
It is power-hungry and filters aren’t cheap compared to other small air purifiers I’ve tested.

PROS

It offers excellent value for your money! It has the lowest cost per CADR across all other small units I’ve tested.
Its performance at quiet fan speeds rivals that of the $349 Dyson HushJet Compact but for a much cheaper price.
You get two separate filters for particles and gases – no more all-in-one cylindrical filters you’ll be throwing away sooner than you need to.
It comes with a high quality laser sensor that provides data on PM1, PM2.5 and PM10 particle levels.
The new app enables a Dynamic Manual mode I’m in love with: you can manually set your Eleva to run at speed 2, for example, while also allowing it to momentarily go up to Turbo whenever the sensor notices a rise in pollutants.

2. Best for most kitchens: Alen BreatheSmart 45i (with Ultimate Odor filter)

This air purifier has a powerful fan that can clean the air in kitchens up to 297 sq. ft. (or 27 m²), removing particle pollution and unwanted cooking smells.

Alen BreatheSmart Flex Kitchen

If you prefer to have your air purifier on the floor, then the Alen BreatheSmart 45i would be my go-to choice. It has a PM1 CADR of 198 cfm when running at top speed that will give you five air changes per hour in kitchens no larger than 297 sq. ft. (or 27 m²).

Similar to the Eleva 300X, Alen also offers different filter options. For kitchen odors, I recommend upgrading to the Ultimate Odor filter which combines H13 HEPA filtration with activated carbon pellets treated with an odor neutralizer.

The 45i also has an ionizer function that can supercharge odor removal, but you don’t have to use it if you prefer to avoid ozone emissions no matter how low they may be.

I appreciate being able to give the unit a wipe whenever any oils or grease ends up on the front cover. This is much more convenient than having to dry clean or wash the pre-filter fabric you get with units like the Blueair 311i Max and the 3000i Series – – those two models didn’t do well in our messy kitchen, unfortunately.

The 45i has a laser sensor that unlocks smart functions, so you can leave it running while you cook and it will switch to top speed whenever it detects pollutants in the air.

Alen 45i controls

I used my Alen 45i in our kitchen for a very long time and really missed it when the time came to switch to a different air purifier, as the kitchen is one of the rooms where we test units. Now my 45i lives in our kids’ bedroom.

CONS

Filters do cost a little more than other brands, but do last up to 12 months.
Higher price for extra features and better build quality than budget air purifier brands

PROS

The buttons on the control panel are clearly labelled, which is something I wish more manufacturers would do instead of icons that may or may not be clear to most people.
It has a high quality laser sensor from Plantower – this is the best I’ve seen used in the air purifiers I’ve tested.
It’s pretty quiet considering its power, with sound levels ranging between 36.2 dBA and 56.1 dBA.
You get lifetime warranty if you subscribe to Alen’s filter replacements.

3. Best for very smelly kitchens: AC Infinity CLOUDLINE S8 fan with refillable carbon filter

This is a specialist device with a refillable filter packed with 16 lbs of activated carbon, which is the most I’ve seen.

AC Infinity Build

Traditional air purifiers will struggle to deal with serious cooking odors or unwanted kitchen smells. In those cases, I recommend building an odor-busting device using AC Infinity’s CLOUDLINE S8 fan, an 8-inch Carbon Filter, two noise reduction clamps and a pre-filter cloth. The whole setup costs around $410.

In our odor removal tests, our AC Infinity running at speed 5 outperformed every other air purifier thanks to its whooping 16 lbs (or 7.2kg) of activated carbon.

Carbon Quantity AC Infinity

And my favorite thing about it is that you can refill the filter once the carbon is used up. This will save you a fortune in the long run.

This device is meant to be installed on the ceiling. Be aware that when using it on the floor, the fan blades are exposed at the top.

To fix this, I cut out a circular piece of carbon-impregnated fabric and placed it above the fan before adjusting the top clamp. This also reduced carbon particles floating around.

CONS

This device only removes gases and odors from the air. You won’t get any particle filtration, so you will need to use it alongside an air purifier with a MERV 13 or HEPA filter if you want to remove smoke particles too. A cheap model could work.
This isn’t a traditional air purifier. You have to build it yourself and it doesn’t come with any fancy touchscreens or smart features.
It is LOUD. When set to speed 5 (optimal speed), it generates 61.9 decibels. The good news is that VOC removal improves at lower fan speeds.

PROS

The 8-inch carbon filter comes with 16 lbs (or 7.2 kg) of activated carbon, which is the largest amount we have seen.
It is much cheaper than specialist odor-busting units from Austin Air, Allerair and Airpura can cost as much as $1,000.
This filter is refillable, so once the carbon is used up, you can dispose of it and refill the cylinder with more carbon.
The price of a years’s worth of carbon is just $89.99! This is A LOT more accessible than the nearly $400 you’re expected to spend on filter replacements with other specialist brands.

Two buying tips for finding a good air purifier for your kitchen

Many studies show that kitchens are a significant source of indoor pollution, including smoke, VOCs, nitrogen dioxide and particulate matter. It’s worth taking the time to ensure that the air purifier you choose will do an excellent job of keeping your air clean whenever you cook.

To find the right air purifier for your kitchen, you need to consider the size of your cooking space, the type of filter and any features you can’t live without.

AirDoctor AD3500 Activated carbon filter pellets

1. To tackle cooking odors, you need a good amount of carbon

Particle filters like HEPA can’t do anything against odors, which are chemicals or gasses in nature. That’s what activated carbon deals with, through a process called adsorption. 

Levoit Vital 100 Kitchen

2. Consider the size of your kitchen

A common mistake is choosing an undersized air purifier for a given space. If the unit is not big or powerful enough, it will consume filters more than necessary, and the air in your space won’t be thoroughly cleaned.

You should consider the air purifier’s Clean Air Delivery Rate (CADR), which is basically a measure for how much clean air the unit can deliver within a given time.

Feel free to input your kitchen size into our calculator below and it will output the CADR you should aim for if you want to achieve 4.8 air changes per hour:
