Design and Size of Sharp KC-850U Air Purifier
In Sharp KC-850U you will find an intake air grill from the back, following the conventional setup of Sharp air purifiers. Here you can open the seal and access the water tank and the air filters within the Sharp KC-850U. The grill is perforated to minimize the size of the pollutant particles that are attracted to your air purifier.
From the top, we'll have a very bright view of the sensor tracker, as well as the humidity level of your room and the water supply tracker. The water tank is mounted on a humidifying tray and is situated next to the main region of the air filters. You can quickly delete it from the air purifier without first uninstalling the filters. Only have to close the tank cap tightly before placing it back again.
At the top of this air purifier, next to the may outlet air vent, we will find a control panel with a lot of feature buttons. It is simply the custom of the Japanese brand because they have always put many features into their apps.
The Sharp KC-850U is 23 inches in height and 15 inches in width, which is close to the size of the Sharp FP-F60UW. Of course, it is heavier with a weight of 21.4 lbs. It's got four handles, to help you move this unit anywhere in your house.
Filters of Sharp KC-850U Air Purifier
The Sharp KC-850U features a very unique humidifying filter along with the conventional 3-stage air purification system as mentioned below.
Activated Carbon Filter: helps reduce the scent of pets and smoke, as well as certain, can household chemicals.
True HEPA Filter: A True HEPA filter that removes 99.97 percent of particles as small as 0.3 microns, such as pollen, dust, pet dander, smoke, germs, bacteria, viruses, odors, molds, and fungi.
Plasmacluster Technology: This device is a single form of an ionizer that can further reduce the number of contaminants. This can be turned on / off.
This brand's efficient True HEPA filter is coated with a layer of antimicrobial filter to prevent the growth of mold spores and bacteria within your HEPA filter. As a consequence, the True HEPA filter will last longer than 5 years.
And here's the unique Plasmacluster technology. Sharp KC-850U, much like the old Sharp tools, can emit both positive and negative ions into the air to form hydroxyls that decompose proteins and suppress virus activity. Such a device could also eliminate static electricity.
Room Coverage of Sharp KC-850U Air Purifier
With the addition of the water tank, there is no more space left for a large fan. The Sharp KC-850U has a very weak fan power at a price, and can only clean a room of 254 square feet.
The Sharp KC-850U ACH is 2X to 4X. For the best air changes every hour, this air purifier will clean your room every 15 minutes.
The Sharp KC-850U CADR is 164 Dust/164 Smoke/174 Pollen (cfm).
Sound Production of Sharp KC-850U Air Purifier
Sharp says the silent activity is the subject of the Sharp KC-850U. It's home to some of the best and most frustrating pieces of the air purifier.
The real calculation of the noise level, at least, is good. Sharp KC-850U can keep the noise level as low as 19 decibels, and this is even quieter than the rustling leaves.
Yet when you transform this air purifier at the highest speed of the fan, the noise level of the air purifier on its own is 50 decibels. When combined with the humidifier function, the noise level can be as high as 60 decibels.
If you want to enjoy the quiet, you can at least lower the level of the air purifier to medium or low. Or without the humidifier feature, this Sharp KC-850U is very quiet and can serve your bedroom well.
Energy Consumption of Sharp KC-850U Air Purifier
An air purifier must be used for a long time in order to be effective. And power usage is an important criterion for evaluating how much energy this air purifier consumes.
The Sharp KC-850U is rated as an Energy Star and will only run at 3.5 watts for the lowest setting. And the average power consumption is still fine, as it is only 50 watts. You also have to count the humidifier's power consumption as well, and the average power consumption can be as high as 93 watts.
When you use the Sharp KC-850U 8 hours a day as an air purifier on your own, you have to pay $0.1 to $18 per year. You can misuse the humidifier feature, but you have to pay $0.25 to $15 more each year. In my view, the combination of this air purifier would consume less energy than two machines with different functions.
Additional Features of Sharp KC-850U Air Purifier
The additional features of this air purifier include the Smart Sensor to tell us exactly the condition of the indoor air through the LED indicator on the front of the air purifier. If you activate Auto Mode, this Sharp KC-850U can automatically adjust the fan power to suit the needs of the air cleaning process.
For example, if the air quality is poor, the Sharp KC-850U will run faster at the highest fan speed to clean the space, and vice versa. It will also indicate the humidity level as well as the numerical value. You will also be warned when the water tank needs to be refilled.
The Sharp KC-850U features a traditional feature of this brand called Fast Clean Mode. Continuously discharge strong airflow cycles and release high-density Plasmacluster ions to remove airborne allergens as they are drawn through filter systems.
In the end, we still have a filter replacement light to remind us when we need to adjust the air filters. The indicator only works for HEPA replacement, so you need to recall the date of the humidifier and the activated carbon filter manually.
