Sharp is bolstering its hybrid air purifier lineup with more models, starting with the Sharp KC-F70-W and Sharp KC-H50-W, which the company announced earlier this year. The Sharp KC-F70-W has already been available on Amazon for a while, and today we will make a complete Sharp KC-F70-W Review to help you compare it with the other Sharp air purifier with humidifier function.
In Breathe Quality, we have reviewed all air purifiers under these sections. Also, we guarantee that:
- We provide honest reviews (both pros and cons) so that everyone can make the best decisions.
- We do not (and never will) exaggerate one product just to let you click the links and buy that product blindly.
- High-quality air filtration system
- Great humidifying system
- High fan power
- Very silent
- Not from official US Sharp store
As the number one air purifier brand in Asia, Sharp comes to the U.S. with only the best and latest air purifiers from its lineup, but we shouldn’t ignore the already good air purifiers for the domestic market. Let’s read our Sharp KC-F70-W Review to check the most-sold air purifier in many Asian countries last year.
Other Sharp’s Air Purifier Reviews:
Sharp KC-F70-W Price
According to Sharp, the Sharp KC-F70-W is among its best air purifiers, with both air purifier and humidifier functions. Apart from these highlight features, the Sharp KC-F70-W has quite high fan power for a more affordable price tag than the Sharp KC-860U.
So, is this new lower mid-range offering worth considering over the current competition? The answer is maybe, as the Sharp KC-F70-W doesn’t have any English instructions, just like the Sharp KC-B50 and Sharp KC-H50-W. It is more than an usual hindrance for U.S. users.
The Sharp KC-F70-W is often sold for just $330, and it is even cheaper than an official Sharp KC-850U with lower fan power. If Sharp can produce more air purifiers like the Sharp KC-F70-W in the U.S. market, we will certainly have a high-quality Japanese air purifier at a much cheaper price.
Again, we don’t see many hybrid air purifiers with humidifier functions at this price point. Only Oreck Air Refresh and Boneco H300 are the most proper competitors with our current unit, but they don’t have the core True HEPA filter inside. And for that, I lean on the Sharp KC-F70-W much more.

Sharp KC-F70-W Design and Size
The body of the Sharp KC-F70-W has a similar design to that of the previous Sharp KC-H50-W. To be fair, Sharp air purifiers are unique in design, but deep in the family, one would be likely to borrow the same design from the others.
We will have an all-plastic body with a bigger size than its predecessor: 25 inches in height and 16.5 inches in width. However, the difference isn’t that big to realize unless you put all the Sharp air purifiers side by side to compare.
As I’ve mentioned before, the Sharp KC-F70-W is exactly the same design as its relative. It has a plain white color with brushed rays on the surface. It also uses a similar bottom-to-top airflow system concept, covered by exactly the same air grills.
Using the same design language as the Korean high-end Winix HR1000, the Sharp KC-F70-W has a top LCD display that is over the top control panel. It is also available in many native air purifiers from Sharp.
As a bigger device, the Sharp KC-F70-W weighs 19 lbs. And this time, you don’t have the casters like in the case of the Sharp KC-H50-W. Well, this time, you need to move it yourself.

Sharp KC-F70-W Filters
Sharp doesn’t change the air filtration system for many years, because it’s so proud of its signature Plasmacluster technology. In this Sharp KC-F70-W, we have a similar 3-stage air filtration system.
- Activated Carbon filter – It helps reduce pet odors and smoke, as well as some common household chemicals.
- True HEPA filter – The True HEPA Filter captures 99.97% of as small as 0.3 microns of 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.
The signature air filtration system of Sharp is present, but without a certification by the California Air Resources Board (CARB) for having a safe ozone emission concentration. It is reasonable because Sharp doesn’t cover any warranties on this air purifier, and the company doesn’t release it as an official product on the U.S. market either.
But don’t get it wrong. All air filters made by Sharp are widely used by many popular air purifier companies at the moment. For example, the True HEPA filter of the Sharp KC-F70-W is high-quality and high-efficiency, and it can last for 2 years before losing its performance.
In addition, we have the signature Plasmacluster technology for this air purifier. This technology is awarded as the best air cleaning method in Japan, as it emits both positive and negative ions into the air to form hydroxyls that decompose the protein and suppress the activity of the viruses. This technology can even remove static electricity and doesn’t release any ozone at all.
If you need a comparison test for this Sharp KC-F70-W with all its brothers, I made one in a room of 200 square feet for 1 hour. I must admit, the Sharp KC-F70-W had almost as high an efficiency as the Sharp KC-860U, but at a much lower price.
For this air purifier, you need to use the air filter model FZ-D70HF.

Sharp KC-F70-W Room Coverage
The Sharp KC-F70-W is capable of much larger rooms than its predecessor, even though the ion density of this air purifier is just 7000/cm³. It is recommended for use in 430 square feet.
The ACH of Sharp KC-F70-W is 4X. This air purifier can clean your room every 15 minutes.

Sharp KC-F70-W Sound
Again, we have another air purifier with the ultra-quiet fan, trademarked as LibraryQuiet operation by Sharp. The Sharp KC-F70-W is measured at only 23 decibels (dB) at its lowest speed, which is the sound of rustling leaves.
On the highest speed, the noise level is 55 decibels, which is a bit audible but not too noisy. If you intend to use the Sharp KC-F70-W in your bedroom, you will be pleased with how quiet the device can operate.

Sharp KC-F70-W Power Consumption
One of our most FAQs is “Do air purifiers use a lot of energy?” In fact, air purifiers must be used for a long time to be efficient. And power consumption is one important criterion for reviewing how much energy this air purifier will consume.
If you run the Sharp KC-F70-W for 8 hours per day, you need to pay $27.5 per year.

Sharp KC-F70-W Additional Features
Just like any mid-range air purifier with a humidification feature, the Sharp KC-F70-W features the Smart Sensor, together with the temperature and humidity sensors, to give you everything you need to know about your indoor air. The auto mode can be enabled to monitor the fan power according to the current air quality status.
I can see the option of Sleep Mode in this Sharp KC-F70-W, and it can dim all lights and keep the fan speed on the lowest. This is also the feature to use when you go to sleep.
Finally, there is a LED indicator for filter replacement, so you don’t need to keep track of the date manually.
Sharp KC-F70-W Customer Service
Sharp is a huge brand; of course it is. 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 good customer service if you live in the United States.
But don’t worry, as the U.S. subsidiary of Sharp is quite active and would like to hear from you. You can reach its customer service toll-free at 800-237-4277 or via email through the “Product Support” page. Sharp’s customer service is available to you 24/7, every day.
However, for air purifiers, the company only provides a 1-year warranty. For most situations, I believe this warranty is enough to cover your device.
For any imported products like the Sharp IG-EX20, Sharp KC-F70-W, Sharp KC-B50 and Sharp KC-H50-W, however, you don’t get any support from this company.
The Sharp KC-F70-W is really a good deal, especially when it costs much less than the Sharp KC-860U. However, without proper customer service and English instructions, it is still very difficult for US users to buy this product. Perhaps it is safe to stick with the model KC-860U.
