Other Cuckoo’s Air Purifier Reviews:
Cuckoo CAC-K1910FW Price
The Cuckoo CAC-K1910FW is priced at the top end of the consumer large-room air purifier category. It is definitely an ambitious air purifier from a newbie South Korean brand, but given that Cuckoo only makes premium products, it isn’t a surprise to see an air purifier that’s expensive.
In the US you’ll pay $799 direct from Cuckoo’s own storefront, with the same model appearing at Amazon and Walmart for comparable pricing. The Cuckoo CAC-K1910FW is competing against the top dogs from South Korean air purifying industry, for example the Coway Airmega ProX or LG PuriCare AS560DWR0.
However, both LG and Coway have built brand recognition for such a long time. Even though Cuckoo is a famous electronics brand, the company is never the first in customers’ minds when buying an air purifier. Selling the Cuckoo CAC-K1910FW at this price range is indeed a risky move, especially when the market is not its homeland.
With both verification from AHAM and Energy Star, the Cuckoo CAC-K1910FW is a lot more reliable than other air purifiers you can find at this price range like the NuWave OxyPure Zero E2000 or Airdoctor AD4000. However, we still have the Alen BreatheSmart 75i, Rabbit Air A3 and Blueair Classic Pro CP7i ready to win, with high performance, smart features and much better annual cost.
Still, the Cuckoo CAC-K1910FW is a great air purifier from the country with full of air purifying expertise. If you love the Cuckoo design, don’t hesitate to buy this flagship for your home.

Cuckoo CAC-K1910FW Design and Size
For some reasons I can’t explain, the Cuckoo CAC-K1910FW is very much alike some Winix models in the past. This look – a no-nonsense upright column – has been Cuckoo’s chosen form for its large room air purifier line, which is different from the console style using in mid-range options.
The Cuckoo CAC-K1910FW has a clean, matte-finish white shell, and it comes only in white. It’s a more ordinary shape too, as Cuckoo has opted for a straightforward cylindrical tower rather than anything architecturally unusual. As usual for Cuckoo’s larger models, the unit makes use of a structural housing that feels solid and substantial for its 15.4 lb frame.
This is a large purifier by any measure, and it feels its size thanks to its substantial 13.2 × 13.2-inch footprint and 25.6-inch tower height – this is a unit which is meant for the price point. There is a side-mounted panel with the two-button control interface rather than an in-screen display, and, just like similarly designed towers, it’s not the most tactile or feedback-rich control surface around.
Overall, it’s indeed the iconic South Korean air purifier with main white color option, simple control panel and lots of LEDs for the Smart Sensor.

Cuckoo CAC-K1910FW Filters
We check the performance of one air purifiers based on its air filters’ quality and material, as well as the number of air filter types in the testing device. The Cuckoo CAC-K1910FW features the most comprehensive
- Pre-filter – The washable pre-filter is able to capture larger contaminates like dust, hair and lint.
- Allergen filter – An extra layer of filter that captures allergy causing particles such as dust mites and pollen, and adds an additional layer of protection alongside the standard filtration system.
- True HEPA filter – The True HEPA filter can capture all ultra-fine particles down to 0.3 microns, with efficiency up to 99.97%.
- Activated Carbon filter – A honeycombed carbon filter protects against household odors from cooking, cleaning products and more.
- UV-C light – Deals with mold spores and viruses. Can be switched on/off.
Cuckoo once became known in the US market for the more modest Cuckoo CAC-I0510FW small-room model. The Cuckoo CAC-K1910FW takes the opposite road, positioning itself as the brand’s large-room flagship with a five-stage system. At this size, a five-stage filtration stack means each particle type is addressed at a different capture layer, meaning no single filter is doing all the heavy lifting.
The key question: does it hold up? The Cuckoo CAC-K1910FW is meant for large rooms, so it takes one of the most difficult tests made by Breathe Quality. The result, it captures 97.73% of all particles down to 0.3 microns. Not that good for a $799 air purifier.

Cuckoo CAC-K1910FW Sound
The Cuckoo CAC-K1910FW is marketed to be one of the best ultra-low noise levels for an air purifier. Despite of its size and performance, the Cuckoo CAC-K1910FW can trim the noise level as low as 21 decibels (dB), which is similar to the sound of rustling leaves.
Even its highest speed is just around 53 decibels, which is far below the maximum fan’s noise level you should expect from a large-room air purifier.

Cuckoo CAC-K1910FW Power Consumption
As one of the most criteria when deciding to buy an air purifier, one of our most FAQs is “Do air purifiers use a lot of energy?”. In fact, an air purifier needs to run for a long time (usually more than 8 hours) to be efficient.
The Cuckoo CAC-K1910FW is registered in the Energy Star database, with a very high integrated energy factor of 5.6. Its rated power is 60 watts, so it uses about half the wattage needed by an old air purifier with such fan power.
If you’re going to run the Cuckoo CAC-K1910FW at least 8 hours per day, the annual cost will be $26.3.

Cuckoo CAC-K1910FW Additional Features

Other than that, the Cuckoo CAC-K1910FW prioritizes simple controls. It has an LED indicator for filter replacement, an auto light dimmer, and that’s it. You don’t have any more features.

Our verdict
The Cuckoo CAC-K1910FW is a decent, average flagship air purifier from the famous Cuckoo brand. It has some strengths in its great annual cost, featuring the Energy Star badge for being energy efficient. However, its performance isn’t the best you could get at this price, and it lacks certain smart features, which is very unlikely for an air purifier from South Korea.
