As one of the top electronics corporations in the world, with more than 100 years of experience in making many household items, Sharp is the very best brand you should look for an air purifier. In fact, the company beats Winix really hard in the Asia region, despite of using the similar air filtration technology. Let’s take a look at the new-gen air purifier of this Japanese company in our today Sharp FP-K50UW Review.
Other Sharp’s Air Purifier Reviews:
Sharp FP-K50UW Price
Sharp FP-K50UW is one of few many air purifiers designed specially for the U.S market. It has an attractive look and a lot of great ideas – including a dual action air cleaning system – but a lot is recycled tech here and it’s hard to recommend when the Sharp FP-F50UW offers a lot of the same with a Smart Sensor. Even the Sharp FP-F60UW is also available with a similar price, and I think Sharp FP-K50UW will lose its advantage.
The top low-range segment is always the most competitive one in the U.S air purifier market. To compete in this segment, air purifiers with high-quality air filtration system are becoming the norm, and Sharp wants to try their hands at making an air purifier that’s more powerful than other competitors.
In the U.S market these days, the company has gained significant impression for making good air purifier with Plasmacluster technology. Though they started a bit late than the South Korea-based Winix, the company is rated quite positive on Amazon, thanks to their verified air purifiers.
However, it seems the COVID-19 pandemic affected the price tag of Sharp air purifiers quite hard. I am never able to confirm the official price tag for each of their air purifiers. The Sharp FP-K50UW price is $229, which is the old price tag FP-F50UW model. I believe Sharp has increased the price due to high demand.
Of course, you can get the Sharp FP-K50UW with a much lower price from our deal, if only it is available. The new price is much more suitable, and it gives Sharp FP-K50UW more advantages in competing with things like Winix C545 or Coway AP-1512HH. If you value the Smart Sensor above the air filtration technology, you can also look for the Vornado AC550, Bissell air400 and TruSens Z-2000.

Sharp FP-K50UW Design and Size
Sharp FP-K50UW features a new design choice you won’t see on any other Sharp air purifiers on the market at the moment. It is clearly a design to aim to the U.S market, because it resembles a lot with the Honeywell HPA300, Rowenta Pure Air PU3040 and Inofia PM1320. It’s the first air purifier from the company to embrace a design with curves from both sides – and it may be to everyone’s taste.
Surely it’s distinct from their own brothers, but I think of the Sharp FP-K50UW’s design much more familiar to us, and honestly I love it. Using the signature white color, Sharp FP-K50UW looks pretty stunning from afar.
Considering the size of this air purifier to be 21.3 inches in height and 15 inches in width, it is the same size of the Sharp FP-F50UW, as well as any Sharp models with “50” in its name. It is quite easy to blend with your home’s decor.
Sharp FP-K50UW not only comes with traditional design style, but it also runs the traditional bottom-to-top air flow system concept of console air purifiers. So the air will first enter the back panel, which acts as a pre-filter with small square holes. Check out the bottom tabs when you replace the air filter.
The top air control panel is quite similar to all other Sharp air cleaning system. There is two LED indicators for both filter reminder and Plasmacluster feature right below the control panel.
We get another Sharp air purifier with only 11 lbs in weight, and yes, there is a convenient handle from the back of this Sharp FP-K50UW.

Sharp FP-K50UW Filters
Running the typical 3-stage air cleaning system, it seems we will have the best air cleaning method awarded in Japan. Let’s take a look at the Sharp FP-K50UW’s air filtration system.
- Activated Carbon filter – It helps reduce the pet odors and smoke, as well as some common household chemicals.
- True HEPA filter – The True HEPA Filter that captures 99.97% of as small as 0.3 microns particles like pollen, dust, pet dander, smoke, germs, bacteria, viruses, odors, mold, and fungus.
- Plasmacluster Technology – This technology is one kind of ionizer, which can further reduce the amount of pollutants. Can be switched on/off.
As I’ve mentioned in many Sharp air purifier reviews, the air cleaning system of the Sharp FP-K50UW is similar to many Winix models, like Winix C535, Winix 5300-2 or Winix 5500-2. It starts with an Activated Carbon filter, a verified True HEPA filter and an exclusive technology named Plasmacluster. It is completely similar to the PlasmaWave, and both air purifier brands consider the technology as their unique selling point.
By releasing both negative and positive ions, the Plasmacluster not only anchors down the pollutants, it also forms hydroxyls that decompose the protein and suppress activity of the viruses. As a result, Sharp FP-K50UW returns invisible water molecules, which is harmless to people. Sharp FP-K50UW has a common density of ions, with 7000 ions/cm3.
And don’t forget the high-quality HEPA air filter of Sharp, which can last up to 2 years. It is still efficient to remove 99.97% of any airborne particles as small as 0.3 microns, meaning it can completely trap the PM2.5 particles.
Sharp FP-K50UW seems to be powerful in its suggested 150-sq-ft room size, as this air purifier can clean 99.93% of all particles down to 0.3 microns, in only 1 hour. It is near the performance of the more expensive Medify MA-40, and it is better than the Bissell air220, Medify MA-25 and Mooka GL-FS32 in the same conditions.
Sharp FP-K50UW runs quite the same filter as the Sharp FP-F50UW, in another name: FZ-K50HFU. At the moment, I can’t find the filter replacement for this Sharp FP-K50UW, just like its smaller brother Sharp FP-F30UH.

Sharp FP-K50UW Room Coverage
When you buy an air purifier that costs around $200, you will expect it to cover around 200 to 300 square feet. The Sharp FP-K50UW is in the middle of this recommendation, with 259 square feet room coverage. It is quite similar to the performance of the Sharp KC-850U.
The ACH of Sharp FP-K50UW is 4X. It is able to clean your room up to 4 times per hour.
The CADR of Sharp FP-K50UW is 171 Dust/ 167 Smoke/ 188 Pollen (cfm). The Sharp FP-K50UW is verified by the AHAM for its performance. Considering it is up to high-level of low-range segment, and it needs fan power to distribute the Plasmacluster ions, this CADR rating is a bit disappointing. However, it is better than the Sharp FP-F50UW, which practically costs more.

Sharp FP-K50UW Sound
Surprisingly, the LibraryQuiet technology is truly good in Sharp air purifiers. The standard noise level test showed that the Sharp FP-K50UW can run as quiet as 22 decibels (db). This result is a lot better than most air purifiers in the same price range, and I believe it is even better than some Chinese compact air purifiers.
Turning the fan power to the highest speed, and the noise level is only 51 decibels. It is just like the normal conversation at home, and I think this is truly the power of Sharp’s LibraryQuiet operation. You get advanced technology that allows for a peaceful night’s sleep.

Sharp FP-K50UW Power Consumption
One of our most FAQs is “Do air purifiers use a lot of energy?” In fact, air purifier must be used for a long time to be efficient. And power consumption is one important criteria to review how much energy this air purifier will consume.
Sharp is widely certified both by the Energy Star and AHAM for its energy-saving efficiency. The Sharp FP-K50UW is one of many models rated as an Energy Star, with the power consumption of only 41 watts. It is actually better than the compact Sharp FP-F30UH in terms of energy saving.
For running the Sharp FP-K50UW 8 hours per day, you need to pay only $15 each year.

Sharp FP-K50UW Additional Features
One important notice, the Sharp FP-K50UW doesn’t have the necessary Smart Sensor. Perhaps Sharp wants to cut cost for their newest air purifier, and the removal of the dust sensor is quite reasonable. You should head to the Sharp FP-F50UW and Sharp FP-F60UW for this luxury additional feature.
It still features many common function of a Sharp air purifier, like the Quick Clean mode, to thoroughly clean your home in the shortest time possible. Sharp FP-K50UW allows you to dim the light, including of the Plasmacluster indicator and filter reminder.
There is a Timer setting for this air purifier, to schedule the time off after 2, 4 or 8 hours. Finally, you have a simple LED indicator for filter replacement.
Sharp FP-K50UW Customer Service
Sharp is a huge brand, of course they are. But this brand is not as popular in the U.S market as it is in the rest of the world. Yes, marketing is one aspect of this unpopularity, but it also implies a difficulty in finding the good customer service if you live in the United States.
But don’t worry, as the U.S subsidiary of Sharp is quite active to hear from you. You can reach them toll free at 800-237-4277, or via email through their “Product Support” page. They are available for you 24/7, and this is one of the best parts for Sharp’s Customer Service.
However, for their air purifiers, they only provide an 1-year-warranty. For most situations, I believe this warranty is enough to cover your device.
Sharp FP-K50UW knows where it sits in the market, a little right below the Sharp FP-F50UW by exchanging the additional features for good use: better fan power, quieter operation and more energy-saving power. It also takes a lot of what made the FP-F50UW model a great device.
Sacrifices the additional features for good use.
