The list of unofficial Sharp air purifiers for the U.S market is adding the Sharp FP-A28UW, which I’m lucky to have one week to test this on. It could be unavailable at the time you check our deal, but I hope the review is still valid for anyone who want to take a look at a Sharp air purifier. So, let’s begin our Sharp FP-A28UW Review.
Updated: You should look for the Sharp FP-F30UH instead, which is officially released for the U.S market, and is backed up with the best customer service from this Japanese company.
In Breathe Quality, we have reviewed all air purifiers under these sections. Also, we guarantee that:
- We do give honest reviews (both pros and cons) so anyone will guarantee to have the wisest choices.
- We do not (and never) exaggerate one product just to let you click the links and buy that product blindly.
- Decent performance
- Compact size
- Very silent
- Not from official US Sharp store
- Shortage of availability
You may don’t know about Sharp air purifiers, but you should’ve heard of this giant international incorporation, with origin in Japan. Moreover, Sharp is the top 1 air purifier brand in Asia region, with the number of device models compared with Coway and Samsung. In our today Sharp FP-A280UW Review, we will check for an air purifier that we hope to be more available on U.S market in the near future.
Sharp FP-A28UW Price
Japanese air purifier brand Sharp hasn’t had as much of an impact on the U.S market, especially when most of their air purifiers are always “out of stock” status, and the official Sharp website for the U.S lacks information to help customers purchase their devices.
The Sharp FP-A280UW is meant for the North America market, but somehow you can’t find information about this air purifier anywhere. Given that the Sharp FP-F30UH, Sharp FP-K50UW and Sharp FP-F50UW are available, I highly recommended to switch to these products for more proper customer service.
This isn’t the first time for a Sharp air purifier, as you don’t know the origin of things like the Sharp KC-F70-W, Sharp KC-B50 and Sharp KC-H50-W, either. They are all well-known in the Asian market, however, but if you buy one of them, you are left alone right after.
The Sharp FP-A28UW first appeared with a price tag of only $129, but it could change later due to increased demand. Probably you won’t find a model of FP-A28UW from our deal, and don’t be sad about this fact.
This air purifier could be a great competitor with many native air purifiers like TruSens Z-1000, Envion Allergy Pro AP200 and Airthereal APH260. There are a lot of Chinese devices for you to take a look in this price range, like the Okaysou AirMax8L, Elechomes EPI236 or KOIOS EPI209.

Sharp FP-A28UW Design and Size
The Sharp FP-A28UW is clearly not built on a tight budget, and it could be the compact device of the famous Sharp FP-A80UW. But for a budget air purifier, one look at it clearly shows that this is the budget air purifier. Rectangular shape, no extra design and no base, the Sharp FP-A28UW is simple and could not make you ‘wow’ about it.
There is no noticeable flex in the body, and you get the simple bottom-to-top air flow system concept for this air purifier. The air outlet is covered with double the grills, which appears only in this Sharp FP-A28UW. I don’t find it appealing, however. The back intake is made with squared panel, and it acts like a pre-filter.
This air purifier has a compact size with only 14.9 inches in height and 14 inches in width, making the air purifier looks like a square unit. Sharp FP-A28UW takes less base than the Sharp FP-F30UH, but it isn’t as solid as its brother, either.
For a budget air purifier, you only get the normal control panel for this Sharp FP-A28UW. Actually, I really like an air purifier with less buttons in the control panel, so the Sharp FP-A28UW is quite good in my opinion.
This could be the most lightweight air purifier in the whole Sharp family, with only 8.2 lbs in total. You can easily move it to anywhere you like.

Sharp FP-A28UW Filters
Just like any budget model of Sharp, the Sharp FP-A28UW doesn’t have an Activated Carbon Filter. Instead, you have only a 2-stage air filtration system as below.
- 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.
Perhaps the signature Plasmacluster is the unique selling point of Sharp, so this company adds it in almost every Sharp air purifier. By emitting both positive and negative ions into the air, this technology can form hydroxyls that decompose the protein and suppressing activity of the biological particles like viruses, mold spores and bacteria. This is awarded as the best air cleaning method in Japan, and works similar to the signature PlasmaWave technology of Winix.
Just like any air purifiers with Plasmacluster technology, the Sharp FP-A28UW is certified by the California Air Resources Board (CARB), because its ozone concentration limit is less than 0.05 ppm. Combining with the high-quality True HEPA filter, this air purifier guarantees an efficiency of trapping 99.97% of any airborne particles down to 0.3 microns.
Again, I ran a few simple tests for this Sharp FP-A28UW, in a room of just 100 square feet. It performed well with high efficiency of trapping 99.9% of any particles down to 0.3 microns in just 1 hour. This efficiency was equal to the Rowenta PU4020, GermGuardian AC5000 and Medify MA-14 in the same price range.
However, it seems the filter cost for this Sharp FP-A28UW is a bit more expensive than other air purifiers in the same price range. However, Sharp recommends to use the air filter for 2 years, so actually the annual filter cost is a lot cheaper than many other brands. The filter model is named FZ-A28HFU, and make sure to only buy genuine Sharp air filter for optimal performance.

Sharp FP-A28UW Room Coverage
Sharp FP-A28UW is only recommended for a room size of 124 square feet by the manufacturer. Up until now, Sharp sent a lot of air purifier units to the Association of Home Appliance Manufacturers (AHAM), and they only recommend the room size based on these tests, so you can fully trust in their suggestion of 124 to 150 square feet.
The ACH of Sharp FP-A28UW is 4X. As an ordinary air purifier, the Sharp FP-A28UW is able to clean your room every 15 minutes.
The CADR of Sharp FP-A28UW is 91 Dust/ 77 Smoke/ 100 Pollen (cfm). Its CADR rating is a bit lower than the Sharp FP-F30UH, but with an additional Plasmacluster technology, the Sharp FP-A28UW has higher efficiency.

Sharp FP-A28UW Sound
The Sharp FP-A28UW didn’t get too noisy with regular use, as on lowest fan speed, the noise level is only 27 decibels (db). Sharp called their air purifiers as LibraryQuiet operation, and they even mark this label on many products.
On highest speed, with Plasmacluster on, the Sharp FP-A28UW can reach 50 decibels. However, this is just the noise level of normal conversation at home, and I believe many people can even sleep with this mode on.

Sharp FP-A28UW 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 FP-A28UW was also sent to be tested by the Energy Star, and it was once compliant with this energy-saving rating. The power consumption of this air purifier is extremely low, with the lowest fan speed is just only 10 watts. On highest speed, I’ve measured the rated power to be only 45 watts.
If you run Sharp FP-A28UW for 8 hours per day, you only need to pay $3.5 to $16 each year.

Sharp FP-A28UW Additional Features
Sharp is one of the best companies for advanced technologies, but for just a budget air purifier like Sharp FP-A28UW, I don’t expect to see many additional features. Turning out, there isn’t any.
Sharp FP-A28UW 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 FP-A28UW is the debut offering for low-end segment, just like the Sharp FP-F30UH. It is sad that the device is usually out of stock, especially when Sharp FP-A28UW has a high efficiency with the combination of True HEPA filter and Plasmacluster technology.
