This new Sharp FX-J80UW is late for the race of smart air purifiers, but it is a solid option to get in mid-range segment, considering the high performance and stable running app. The Sharp FX-J80UW at launch had everything to directly compete with the Rabbit Air MinusA2 – our current reviewed best air purifier.

Sharp, with more than 100 years as one of the top electronics manufacturers in the world, is always the top-of-mind brand when selecting air purifier for home. Though the presence of this Japanese company in the U.S market is still low, with the increase in air purifier models recent years, we hope to see Sharp as a force like Winix in the past. The Sharp FX-J80UX is their flagship at the moment, and with more advanced features, we all expect this air purifier to join the list of best air purifiers soon. But first, you should check our Sharp FX-J80UW Review.

Sharp FX-J80UW Price
Sharp began new decade in the U.S market strongly, with 2 new air purifier models to fill the gaps in both low-range and mid-range segment. The first Sharp FP-K50UW is suitable to be the newest budget Plasmacluster air purifier of Sharp, while our today Sharp FX-J80UW is expected to be a mid-range contender.
At launch, the Sharp FX-J80UW returns the taste of a common Sharp air purifier, something which is missed from design of things like Sharp FP-A80UW or Sharp KC-860U. It is also the flagship model of this company, bringing the Wi-Fi capability for the first time in the U.S. That is, you will get a powerful air purifier, and control it anywhere in your large home.
This large-room air purifier is what the power users have been anxiously waiting to upgrade to, so Sharp FX-J80UW is a bit pricey, but nowhere near the high-range price of many air purifiers like Alen BreatheSmart 75i, Molekule Air or Blueair Classic 605. You only need to pay $599 for this air purifier. However, I must warn you the official price tag of Sharp air purifiers often change, so you should check our deal for the most accurate result.
If your wallet can handle the Sharp FX-J80UW, so you can easily check for the Medify MA-112, Aprilaire Allergy+Pet9550, AIRMEGA 400 or Dyson HP04. Moreover, I recommend you to further research about the Dyson Pure Cool Link, Dyson Pure Cool Tower and Dyson Pure Hot+Cool for extra functions besides the air purifying use. The top products of these Dyson air purifier lines are around the same price as our today Sharp FX-J80UW.

Sharp FX-J80UW Design and Size
You best like futuristic-looking design from new air purifiers, because it gives us a feeling of using ‘high-end’ product. Sharp FX-J80UW maximizes the original design concept that you can only find on native Sharp air purifiers for domestic market, for example Sharp KC-F70-W or Sharp KC-H50-W. It’s impressive-looking, but also big and heavy, something that Sharp FX-J80UW prepares to show off, as it is mainly for large room coverage.
So it is huge, with the height of Sharp FX-J80UW is 28.7 inches, as big as even the biggest tower air purifiers like Blue Pure 121, Rowenta Intense Pure Air XL PU6020 or TruSens Z-3000. Of course, as a console air purifier model, this device has bigger base with 16.4 inches in width and 11.5 inches in depth.
So Sharp keeps topping themselves, launching air purifiers with bigger size than anything of the past, even bigger than the Sharp FP-A80UW with the same “80” in its name.
What really makes the Sharp FX-J80UW superior is its extra clean and simple design for a bottom-to-top air flow system concept. It uses a back panel as the pre-filter, to cover the air intake. Also, you will find the top louver of Sharp FX-J80UW to be a lot more stylish than normal air outlet grills of other air purifiers.
The entire front of this air purifier is clean with only an iconic Plasmacluster symbol and Sharp logo. It saves the spotlight for the front display of Sharp FX-J80UW, where you can manage a lot of information about your unit and indoor air quality index. Above the display, there is a much more complex control panel than other Sharp air purifiers, meaning this flagship packs more additional features.
Let’s see if you can physically manage this air purifier, because Sharp FX-J80UW is heavy at 24.3 lbs in weight. There are two handles to lift this air purifier, but I find it quite inconvenient to use.

Sharp FX-J80UW Filters
Sharp doesn’t change the exclusive air filtration system a bit, even for the flagship Sharp FX-J80UW. At its core, we have a 3-stage air filtration system as below.
- 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.
Sharp FX-J80UW doesn’t need a lot of mechanical air filters, because its Plasmacluster is really powerful, as it is different from a normal ionizer. This technology is also similar to the PlasmaWave from Winix products, releasing both negative and positive ions to the air. Therefore, you can consider the giant Winix T1 as one of Sharp FX-J80UW’s competitor.
While the normal ionizer only emits negative ions to weigh down the pollutants, the Plasmacluster ions can form hydroxyls that decompose the protein and suppress activity of the viruses. The result of this process is harmless water molecules, which return back to the air invisibly.
Plasmacluster ions are proven to be effective by 17 tests made worldwide in the United States, UK, Germany, Japan, South Korea, China and Vietnam, so we can all trust in Sharp FX-J80UW. Lab tests show that Sharp FX-J80UW can reduce 90.2% of MS2 viruses, 94% of E. Coli, up to 84.3% of staphylococcus epidermidis bacteria, 87.7% of mold and fungus in 4 hours. Also, the Plasmacluster can tackle odors, efficiently support the Activated Carbon filter in trapping odors that are embedded in carpets, drapery, and furniture.
Finally, not all Plasmacluster air purifiers are the same, and the Sharp FX-J80UW is the best air purifier using this exclusive Sharp technology. It has the highest density of 25000 ions/cm3, a lot better than common Sharp air purifiers with only 7000 ions/cm3.
There’s another reason the Sharp FX-J80UW is so powerful: this air purifier uses very high-quality in-house air filters, which are made in Japan. I relish the fact that many popular air purifier brands are relying on Sharp air filters today, and its HEPA air filter can last up to 2 years.
Despite of its strong specs, I put the Sharp FX-J80UW through common test of Breathe Quality, to measure its performance in a room of 300 square feet, for 1 hour of running. The result, our today unit has a very high efficiency of trapping 99.95% of airborne particles down to 0.3 microns. However, the performance is still a bit below Blueair Classic 480i, but the difference is really slight.
We will use the HEPA filter model FZ-J80HFU and Carbon filter model FZ-J80DFU for this Sharp FX-J80UW. Both air filter can last for 2 years, with the cost of HEPA filter to be only $89, so it is actually cheaper than you think. Below is a deal for this air purifier’s filters at the moment, and I hope you can get filter replacement easily.

Sharp FX-J80UW Room Coverage
Sharp isn’t so great at delivering air purifiers with high fan power, but they send all units to be certified by the Association of Home Appliance Manufacturers (AHAM), so you can trust any room size’s suggestion for Sharp products.
It seems Sharp is really smart about the Sharp FX-J80UW’s room coverage, and that’s good news because the capability is actually better than most other products in Sharp family. Sharp FX-J80UW is fully capable of covering 502 square feet.
The ACH of Sharp FX-J80UW is 5X. You more than likely going to having clean air every 12 minutes, which is the best ACH rating for a Sharp air purifier.

Sharp FX-J80UW Sound
Here’s the short of it: the LibraryQuiet technology of Sharp is the best among air purifiers in the world. It is especially incredible for the Sharp FX-J80UW, because this flagship has a very high fan power.
Sharp FX-J80UW’s lowest fan power is just like the rustling leaves, with a noise level of only 15 decibels (db). It is currently the most silent air purifier in the world, with a decent performance on low speed.
What’s really amazing is how far Sharp has progressed in this year, with the highest noise level of this Sharp FX-J80UW is only 49 decibels. For an AHAM certified air purifier, with higher CADR rating that matches even high-range machines, the Sharp FX-J80UW’s silent operation is simply perfect.

Sharp FX-J80UW Power Consumption

Sharp FX-J80UW Additional Features
The Sharp FX-J80UW sits on top of Sharp family, so it packs with lots of high-end additional features. The most concerned and expected feature is obviously the IoT Wi-Fi Enabled feature. IoT (or Internet of things) is the word that Sharp wants to use in their latest products, which is not limited to only air purifiers. By giving devices AI (artificial intelligence) capabilities, Sharp connects not only air purifiers, but any un-networked products to help users control them easily.
In short, the Sharp FX-J80UW is one link in a chain of smart devices made recently by the Japanese company. You can connect it with Wi-Fi, to manage indoor air quality in real-time everywhere. It also reminds you when to change the air filters.
Sharp FX-J80UW has both dust and odor sensors to detect even the tiniest airborne particles. Reacting with the changes of indoor air quality, this air purifier can enable the Auto Mode to automatically adjust the fan speed to match the environment’s need.
Moreover, Sharp FX-J80UW shows you everything you need to know about your home’s air quality. It shows both humidity and temperature in digital displays. You can also check the current wattage information from the front display of this air purifier.
As an air purifier meant for bedroom use, Sharp FX-J80UW has a light sensor to automatically dim the light on display. Also, the Sleep Mode will make the air purifier run as quietly as possible.
When you are in haste of cleaning your home, you can turn on the Express Clean mode and let Sharp FX-J80UW go full speed in 60 minutes. It is recommended to use this setting when you turn off the air purifier for a long time.
Together with the Express Clean mode, Sharp FX-J80UW has a Plasmacluster Ion Spot mode, to fully remove adhering odors, germs and other substances from specific places like sofa, curtain or clothes rack. It is only available in this air purifier, because it has the highest density of Plasmacluster ions.
Sharp FX-J80UW returns many basic settings from old models like a Child lock function to prevent any changes of settings, or a Timer to schedule the time off from 1 to 12 hours. There is an Auto Resume setting for this air purifier, too, to restore the previous setting, provided that you don’t unplug the device.
Sharp FX-J80UW 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.
The Sharp FX-J80UW is the best air purifier with smart features from the Japanese company you can buy. It’s artfully designed as the original devices of Sharp, making it manageable and very stylish. It takes the world’s best Plasmacluster ionizer, a verified high fan power and even quieter operation than any previous air purifiers.
But the potential of this Sharp FX-J80UW, and its main selling point is the IoT Wi-Fi Capability feature. For the first time, we have a fully smart Sharp air purifier, and that is what you need to get over the one figure: its high price. Sharp FX-J80UW has everything to go head-to-head with any high-range air purifiers at the moment, and I would love to see it compete in our list of the best air purifiers.
The best Sharp air purifier, and one of the best air purifiers, you can get.
