Sharp is a Japanese multinational corporation, with more than 100 years old in history of designing and manufacturing electronic products. They have been a long-time leader in the whole Asian region, but just like Coway, they only send few of representatives to the U.S market. Today, we will start with our Sharp FP-F50UW Review.

Sharp FP-F50UW Price

The Sharp FP-F50UW stormed onto the scene in 2016 sporting a, well, sharp design and good specs. It is made to be an instant hit at the budget end of the air purifier market. However, I believe that the Sharp FP-F50UW does not have an affordable price anymore, because more and more other brands can keep the price below $200. Even with a recent cut of $50, the Sharp FP-F50UW is still far from what Winix and Coway can do.

It slotted in below the Sharp FP-F60UW, propping up Sharp’s Plasmacluster and Quick Clean mode at the competitive low-range price point. Yes, the Sharp FP-F50UW costs you $279, which is a bit more expensive for the entry-level air purifier of Sharp. It also makes path for the new Sharp FP-F30UH and Sharp FP-K50UW. Actually, I quite miss the time this air purifier’s price drops to just only $177 in the past.

But to be fair, the top competitors that can threat the position of Sharp FP-F50UW are even with $200 or less. The trio from Winix: Winix 5300-2, Winix 5500-2 and Winix C535 are having the similar technology and better fan power, but with a much more enjoyable price tag than this device.

It has also been replaced by the Sharp FP-A80UW and later, Sharp FX-J80UW. Though you may find the air purifier available with our deal below, it seems this company completely ignore the entry product. It is not easy to find the filter replacement, and you can see a lot of complaints for this issue on Amazon.

Sharp FP-F50UW Design and Size

Like all recent air purifiers the Sharp FP-F50UW has a white coat for the whole body. With rounded (not sharp) edge, this air purifier looks a lot like the GermGuardian AC9200WCA or Alen BreatheSmart FIT50. Of course, the smooth plastic is used to cover the back and front of this air purifier. That shell actually improve the bright color in the Sharp FP-F50UW, which can’t achieve by any other colors, though.

The base of this air purifier is way much smaller than normal, but the Sharp FP-F50UW is bigger in the bottom and it is really hard to make it laying on the ground. For the dimension, the Sharp FP-F50UW is 21.6 inches in height and 15 inches in width. This size is normal for a portable air purifier, and the white color can easily match your decor. It is also the color language for the next Sharp FP-K50UW.

The Sharp FP-F50UW features a bottom-to-top air flow system, with the air intake grill from the back. So to say, you must place this air purifier with a distance from the wall or other furniture so it can operate properly. The air outlet is set on top and near the air intake, so the fan won’t need to be as powerful as in a 360° air system like Honeywell HPA300.

This air purifier has a little bit complex control panel. It is reasonable, because the Sharp FP-F50UW packs lots of feature on it.

Sharp FP-F50UW Filters

When we decide to buy an air purifier, we need to know about the air filtration process and what air filter types are used. Sharp FP-F50UW represents the Japanese strongest air filters, with a 3-stage air cleaning system.

  1. Activated Carbon filter – It helps reduce the pet odors and smoke, as well as some common household chemicals.
  2. 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.
  3. Plasmacluster Technology – This technology is one kind of ionizer, which can further reduce the amount of pollutants. Can be switched on/off.

You may be surprise, as the air cleaning system in this Sharp FP-F50UW is similar to exactly the Winix C535. The only different is the name of its technology, as Sharp called it Plasmacluster, while the Winix named it PlasmaWave. However, the Plasmacluster technology has a same working mechanism, emits both negative and positive ions, to form hydroxyls that decompose the protein and suppress activity of the viruses. This technology can even remove static electricity.

The True HEPA filter from this Sharp FP-F50UW is the high-quality one that can remove any common household allergens such as dust, pollen, pet dander, and smoke from the air. With more filter media, this air filter can last for 2 years, which is 2-4 times longer than the normal HEPA filter.

There are many candidates to compare with the performance of this air purifier. So I chose the strong contestants, the Coway AP-1512HH, AeraMax 300 and the Blue Pure 211. They will all run in the same testing conditions: a space of 150 square feet, a duration of 1 hour. As you can see from the below chart, the Sharp FP-F50UW is quite weaker than others, with only efficiency of 99.92% for trapping any allergens as small as 0.3 microns in size.

But don’t worry, as in real-world use, such efficiency is too high for a portable air purifier. And the filter cost (model FZ-F50HFU) of the Sharp FP-F50UW is about $86, which means $43 for the annual filter cost. It is quite good, especially when compare with the high filter cost of the Winix C535 or Oransi OV200.

Sharp FP-F50UW Room Coverage

One biggest drawback for the performance of this Sharp FP-F50UW is the weak fan. For a cheaper price, a Honeywell HPA300 can double the CADR rating of the Sharp FP-F50UW with ease. The manufacturer suggest to use this air purifier for a room of 210 square feet, and it is quite sufficient for the fan power.

The ACH of Sharp FP-F50UW is 4X. With this air changes per hour rating, this air purifier can clean your room every 15 minutes.

The CADR of Sharp FP-F50UW is 153 Dust/ 133 Smoke/ 155 Pollen (cfm). If you need an air purifier that can clean your room faster, you should look for the Winix 5300-2 or Honeywell HPA200. They are only below $200, and have the same quality for the air filters as the Sharp FP-F50UW. In fact, even the cheaper Sharp FP-K50UW has a better fan power than our today reviewed unit.

Sharp FP-F50UW Sound

But, as a unspoken rule, a weaker fan means a more silent air purifier. The Sharp FP-F50UW has 3 fan speeds, and if you are running this device, you will enjoy the exclusive LibraryQuiet operation of the Japanese company.

I measured the lowest noise level of this Sharp FP-F50UW only 29 decibels, and it is even more silent than the whisper. Even if you switch to the highest setting, the noise level is only 45 decibels (db), and won’t annoy you at all.

Many people have complained about the crackling noise of the Plasmacluster, but in 2 weeks of testing, I’ve never heard any sound like this from my Sharp FP-F50UW unit. I will update the status as soon as I find anything wrong for you. But until then, I believe this is one of the quietest air purifiers in the world.

Sharp FP-F50UW 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.

The Sharp FP-F50UW is Energy Star rated, and it will only run at 32 watts for the lowest setting. But if you need to run it on highest speed, the rated power will be 64 watts, and it is a bit higher for an air purifier with weak fan like Sharp FP-F50UW.

For running the Sharp FP-F50UW 8 hours per day, you need to pay $11 to $23 each year.

Sharp FP-F50UW Additional Features

It is more and more popular for a low-range air purifier to have many additional features. In fact, this is the top selling point for a budget device, especially when it needs to trade off both the air filter quality and the fan power to effectively cut cost. The Sharp FP-F50UW is a great example for a budget air purifier with lots of additional features.

First, we need to mention the great Smart Sensor of this air purifier. It can precisely detect the status of the air pollution, and react immediately with the Auto Mode, that change the fan speed to help clean your room better. It also tells you what happens in your room via the light indicator on top of the control panel. I know, it is quite convenient, right?

Do you see the button with a cluster of grapes? This is the button to turn on/off the Plasmacluster function. Sharp said that when water molecules surround ions that are generated by plasma discharge, the result looks much like a cluster of grapes.

The Sharp FP-F50UW also has a great Child lock function, to prevent your kids from accidentally change the settings of this air purifier. And finally, you have the Timer. Remember to hold it 3 seconds to end the Timer setting if you need.

Sharp FP-F50UW 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.

Our verdict

The Sharp FP-F50UW looks good, and the combination of both True HEPA filter and Plasmacluster is the unique selling point of this air purifier. However, for the price, this air purifier is overpowered by many great names in the market, like Honeywell HPA300, Coway AP-1512HH or Blue Pure 211.

Sharp removed the Sharp FP-F50UW on its website, so I guess the product has been discontinued.
