Sharp KC-H50-W Air Purifier: Trusted Review & Specs

Stuck in the middle with a whole lot of Sharp series air purifiers, the Sharp KC-H50-W may get lost in the crowd. It’s a solid, if simple, Plasmacluster air purifier that doesn’t have much to really shout about, but it has the casters that aren’t included in the Sharp KC-B50. So, let’s read our Sharp KC-H50-W Review before deciding which Sharp air purifier to buy.

Update: If you want an air purifier with stronger performance, you should look for the Sharp KC-F70-W. However, I recommend you get the Sharp KC-P70UW or Sharp KC-P110UW to be covered by Sharp’s warranty in the U.S.

Sharp KC-H50-W ranks B in our air purifier ranking list. We give the biggest and most thorough database of air purifier reviews in the world.

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.

Sharp may not be the most popular brand in the United States, but this company is an electronics giant not only in Japan but also in the whole Asia region. Air purifiers are truly the strength of this long-standing company, with its HEPA technology being used by lots of other big air purifier corporations, for example Levoit and Levoit (and many more). Today, with our Sharp KC-H50-W Review, we will take a look at a very popular air purifier for the domestic market.

Sharp KC-H50-W Price

This air purifier, again, is in the same product line as the Sharp KC-850U, using a humidification function to support the main air purifier feature. It shows that you don’t have to spend a fortune to get a good hybrid Sharp air purifier. It’s good value and has all the basics covered.

While the Sharp KC-860U is rightly getting a lot of attention, Sharp has also crafted new air purifiers for those who can’t afford or can’t justify the cost of its flagships. The Sharp KC-H50-W is something like this, with an affordable price tag of $325, which is just like the new Sharp FP-F60UW.

For what you pay, you can now get the Oreck Air Refresh or Boneco H300 instead. Both of them only serve the inferior HEPA-type air filter, so I think the Sharp KC-H50-W is still the better option in terms of air purifying efficiency. If you are looking for higher performance, the Sharp KC-B50 and Sharp KC-F70-W are certainly worth your money.

Sharp KC-H50-W Design and Size

Out of all of Sharp’s air purifiers with humidifying functions, the Sharp KC-H50-W has the best mobility. It has 4 casters, so you can move the air purifier anywhere in your home.

It is a little shorter than the Sharp KC-B50 with only 24 inches in height and narrower with 16 inches in width. The Sharp KC-H50-W keeps the same design language as other native air purifiers, with brushed rays on the surface of the body instead of the normal diamond shape.

On the back, you will find the air inlet grill for a simple bottom-to-top airflow system concept. This Sharp KC-H50-W raises the LCD display over the top control panel and hides the air outlet behind. If you are familiar with the Winix HR1000, you will like this design of the Sharp KC-H50-W.

Sharp air purifiers are normally heavy, and the KC-H50-W is no exception, at 17 lbs. You should appreciate the casters because they help you move the air purifier from room to room easily.

Sharp KC-H50-W Filters

Again, we have a simple yet high-quality 3-stage air filtration system from the Sharp KC-H50-W.

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

Again, Sharp offers superior air filters for a reasonable price. For example, you can get a honeycomb carbon filter, which increases the efficiency of trapping odors and chemicals a lot more than the normal carbon sheet. And don’t forget the powerful HEPA filter, which can last for 2 years in the conditions of the U.S. environment.

Moreover, we have the signature Plasmacluster technology. Just like other Sharp air purifiers, the Japanese-awarded technology can emit 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.

To help you compare the performance of this Sharp KC-H50-W with its brothers, I gathered all Sharp air purifiers with humidifier functions and tested them in the same area of 200 square feet. The Sharp KC-H50-U turned out to be even better than the Sharp KC-850U, which costs a bit more.

You can use the Sharp air filter model FZ-D50HF for the Sharp KC-H50-W, thanks to our convenient deal below.

Sharp KC-H50-W Room Coverage

The Sharp KC-H50-W is only recommended for a room of 260 square feet, as the ion density of this air purifier is just 7000/cm³. Sadly, Sharp doesn’t release the best air purifiers to the U.S. market, so we should be satisfied with the basic air purifiers like the Sharp KC-H50-W.

The ACH of Sharp KC-H50-W is 4X. This air purifier can clean your room every 15 minutes.

The CADR of Sharp KC-H50-W is 180 cfm in general, which is lower than the flagships like KC-860U or KC-F70-W.

Sharp KC-H50-W Sound

Sharp is a company that cares a lot about quiet operation because its air purifiers are mainly for personal use. The Sharp KC-H50-W is a symbol of keeping noise levels as low as possible, reaching only 20 decibels (dB) at its lowest speed. Yes, this is just the noise of the rustling leaves.

More impressively, the highest noise level is just 52 decibels, and you won’t be disturbed by such noise. Perhaps only the Sharp KC-B50 can be better in terms of the silence.

Sharp KC-H50-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.

The Sharp KC-H50-W has a rated power of only 54 watts, which is the same as the Sharp KC-B50, but it is a little bit higher than the Sharp KC-850U.

If you run the Sharp KC-H50-W for 8 hours per day, you need to pay $20 each year.

Sharp KC-H50-W Additional Features

Being a fairly affordable air purifier, however, the Sharp KC-H50-W is still in the mid-range segment, so it needs to pack the Smart Sensor – a feature to track not only the air quality index but also the temperature and humidity level of your room. In addition, the Auto Mode of the Sharp KC-H50-W can adjust the fan automatically to match the environment’s needs.

For one thing, you get a Sleep Mode, which dims all lights and keeps the fan speed at its lowest. It is convenient to have it in the bedroom, though you can turn it anywhere if you don’t want to be disturbed.

The Sharp KC-H50-W has a filter indicator to remind you when to change the HEPA filter.

Sharp KC-H50-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.

Our verdict

Again, I must warn you that the Sharp KC-H50-W is designed for Japan only, so you can’t find any English manual for this air purifier. Also, it comes with a 100V output, and you need a power adapter to change the output for this air purifier. The device also has lower performance than the Sharp KC-B50 and Sharp KC-F70-W, so I recommend you get these air purifiers instead, as the price isn’t much different.
