Sharp’s Plasmacluster line of air purifiers is equipped with a patented feature called “Plasmacluster Ion Technology.” These air purifiers release charged ions into the air, bind themselves with microorganisms, and then get rid of them. This powerful feature also works with pollutants that are trapped in fabric and upholstery.
Aside from Plasmacluster, these Sharp air purifiers also come two other features that complete their “Triple Action” functionality. They have a True HEPA filter, and they also come with a humidifying function.
There are different models under the Plasmacluster line. One of them is the Sharp KC-850U, an air purifier ideal for rooms up to 254 square feet. An example is your child’s bedroom.
In this post, we give you our Sharp KC-850U Plasmacluster air purifier review. What are this model’s pros and cons? Read on to find out.
Key Features of the Sharp KC-850U
Here are the main features to expect.
As advertised, the Sharp KC-850U has three main features: Plasmacluster + True HEPA + Humidifier. It’s made to purify the air you breathe at home while balancing the relative humidity.
It has a dual-stage filtration system consisting of two filters – activated carbon filter and a True HEPA filter, which work together to eliminate particles as small as 0.3 microns. The carbon filter lasts up to 5 years and is washable.
Air Quality Control System
This air purifier has sensors that monitor the air quality of the room. Based on this detected quality, the fan speed is adjusted to make sure the optimum levels (both humidity and air purity) are met.
Room Coverage Area
As advertised, it can cover up to 254 square feet, making it the ideal air purifier for your bedroom.
Pros and Cons
In this part of our Sharp KC-850U Plasmacluster air purifier review, we give you the pros and cons of this product, based on what previous buyers have said about their unit.
Is it quiet?
Sharp says that the Sharp KC-850U produces only 19 dBA on its lowest setting if you’re using only the air purifier function. It produces 23 dBA on the lowest setting if your’e using both the humidifier and air purifier functions.
What do previous buyers say?
Several people have complained of a “ticking” sound especially at the lowest fan speed or when they turn on the Ion feature. At the highest setting, some people say it’s “fairly loud.”
Odors, Dust, and Allergens
One person said that after using this unit for only a few weeks, she noticed a difference in the air quality of their home. Bad smell and odors are also reduced.
Another person said she didn’t get the allergy this year all because of this unit.
Although the humidifier function is not as powerful as you’d hope, one person who lives in Arizona says that the Sharp KC-850U helps add some humidity to the dry air of the place.
- Nope, this air purifier doesn’t have an odor sensor. It doesn’t have a timer either.
- The humidity level cannot be adjusted to the desired measurement.
- You can’t add essential oils into the water tank. This doesn’t double as an aroma diffuser.
Some say it’s difficult to clean.
Our Recommendation: Sharp KC-850U Plasmacluster Air Purifier Review
So…should you get one? Here’s our recommendation.
Based on consumer feedback, this unit is a better air purifier than a humidifier. It cleans the air, reduces odors, and alleviate allergic reactions. And although it can add humidity to dry air, it’s not as powerful as you’d like.
