How Do I Clean My Sharp Air Purifier Filter?

How To Wash The Water Tank: When Humidifying

Rinse the inside of the tank by leaving a tiny quantity of lukewarm water inside, tightly sealing the tank cap, and shaking it. However, you can also clean the inside of the tank using mild household detergents. 

Ensure the detergent is diluted and the tank cleaned thoroughly. To eliminate any detergent residue, ensure the dish is properly rinsed. 

The back of the tank cap has a little cap that is removable. When the tank cap and tiny cap become filthy and slimy, it’s necessary to clean. However, use a cotton swab or a toothbrush to clean the area.

How To Maintain A Washable Deodorizing Filter: Hand Wash Only

Rinse the washable deodorizing filter in lukewarm water to remove dirt. However, before cleaning, remove any dust from the washable deodorizing filter.


  • If you’re washing the filter for the first time, the rinse water might be brown. This doesn’t affect the deodorization operation.
  • When washing the filter, avoid bending or folding it.

Completely Dry Your Filter In A Well-Ventilated Environment 

If feasible, dry it outside. To avoid warping, dry the filter in a sideways position. It takes around 6 hours for the filter to dry out.


  • If it’s raining or chilly outside, don’t dry your filter outside. Allowing the filter to freeze is not a good idea.
  • Take precautions, such as laying towels, etc., if the filter is dried indoors. To avoid water damage to the floor, place the towel under the filter.

How Often Do You Change Filter of Sharp Air Purifiers?

Sharp air purifiers’ HEPA filters are expected to last up to 10 years. However, the time it takes to change the filter is determined by the amount of pollution in the air and the room size. Sharp air cleaners with intelligence will alert the user when the filter needs to be replaced.

Is Sharp Air Purifier Washable?

The air purifier sucks air in the room through the air intake, filters it with the 3 air filters before discharging it through the air outlet. As odors flow through the washable deodorizing filter, they are progressively absorbed.

How Effective Is Sharp Air Purifier

The HEPA filter has a 99.97% dust collection rate, which means it can easily capture and eradicate 0.3-micron dust particles. Allergies are caused by pollen from trees and grasses. In addition, dust mite, animal dander, and mold are also allergens.

Do Sharp Air Purifiers Feature Plasmacluster Technology?

A plasmacluster ion generator in Sharp Air Purifiers releases positive and negative ions into the air. Plasmacluster ions travel across the room, transforming hydrogen molecules in the surface proteins of airborne pollutants into water.

How it works

Stage 1

Plasmacluster ions are analogous to natural positive and negative ions. The ions are released into the air, surrounded by water molecules.

Stage 2

When hydroxide (OH) radical ions bind to the surfaces of airborne microorganisms including suspended allergens, and other pollutants, they become extremely oxidizing. They break down surface proteins by removing hydrogen from them.

Stage 3

The hydroxide (OH) radicals react with hydrogen (H) to create water (H20), which is released back into the atmosphere.

Do Sharp Air Purifiers Produce Ozone?

Sharp Plasmacluster Air Purifiers produce no ozone, unlike traditional ionizers found in many other air purifiers, which produce ozone as a by-product. It emits less than 0.01 ppm of ozone naturally (particles per million).

Is A Sharp Air Purifier Safe?

The safety of consumers is one of the priorities of every manufacturer. It’s claimed that no matter how high the ions’ density of a Sharp Air Purifier is, it’s safe and effective.

Do Sharp Air Purifiers Tell Air Quality?

It can be challenging to see the particles that flow in the air. However, Sharp Air Purifiers have a color display that allows you to see what’s in the air. In addition, it automatically monitors and reports your air quality and the ambient humidity level.

List Of Sharp Air Purifier Models

There are different sizes and operating functions of air purifiers produced by Sharp. Fortunately, it is done to meet customers’ preferences and purchasing power. 

Below is a list of Sharp Air Purifiers:

Sharp FXJ80UW Air Purifier

The Sharp FXJ80UW is a high-performing, Wi-Fi-enabled air purifier, but it has a steep learning curve and a complicated and demanding setup process. During the COVID-19 pandemic, indoor air quality has become increasingly important. 

Studies regularly show that indoor air quality is lower than outdoor air quality. Therefore, being confined to one’s house may raise the risk of allergic reactions or exacerbation of illnesses such as asthma. 

The Sharp FXJ80UW air purifier is programmed to help you breathe easier with a two-pronged strategy to remove common airborne allergens and pollutants. However, it can be challenging to use even though it is jam-packed with useful features and technology.

The FXJ80UW is a large air purifier designed for large spaces. The machine measures 28.7 x 16.4 x 11.5 inches (HxWxD) and weighs 23.8 pounds. It is designed to clear the air in rooms as large as 502 square feet.

This is because an appliance of this size will be apparent wherever it is placed. The FXJ80UW accomplishes this with a straightforward design that places most of the controls and settings on the top panel. For example, the power button, controls for adjusting the fan speed, cleaning modes, and the front display are all located on this panel. 

There’s also a lock button so no one can mess with your settings. An air quality monitor light is located beneath the front panel of the device and changes color that represents room air quality. At the extremes, blue denotes that everything is okay, and red denotes that it’s probably time to open the windows.

Under this light, the front display shows more information about your interior air quality, such as temperature, humidity, and so on. It can also inform you how much energy the unit consumes, the filter time replacement, and the time duration of the timer setting. Furthermore, there are so many functions and options that you should keep the user manual until you’ve mastered them all.

HEPA filtration and Sharp’s Plasmacluster Ion Technology are used to clean the air in the FXJ80UW. The first filter traps dust and other big particles, followed by an active carbon deodorizing filter. Finally, a HEPA filter is certified to collect 99.97% of particles as small as 0.3 microns.

Set up and performance

Pull off the back panel, remove the filters, remove them from their plastic bags, and reinstall them before operating the air purifier. Then, replace the rear panel, plug the device in, and turn it on once that’s done.

The Sharp Air app for iOS and Android may control the FXJ80UW from its control panel or remotely. However, you must first establish an account and sync your purifier with your smartphone to use the app. That’s generally a simple procedure, but this one was a little more complicated and demanding than others.

Sharp FP-J60M-H

Sharp’s latest ‘J’ air purifiers come with many functions. However, its price varies between Rs 19,250 to Rs 38,000. Our assessment is based on the J60, which has all the J series’s features. 

With a Clean Air Delivery Rate (CADR) of 396 cubic meters per hour, the J60 is suitable for big bedrooms or living areas. Despite the huge coverage area, it’s relatively silent, thanks to some creative engineering. As a result, the sound is not overbearing, even at full speed. 

Sharp’s Active Plasmacluster ion technology removes PM2.5 and PM10 particles, as well as airborne molds, allergies, viruses. There are only a few purifiers that provide this level of deep cleansing. In addition, the Spot mode is a fantastic new function that isn’t found on many air purifiers. 

The unit in Spot pumps high-speed air out the device front, making it simple to aim the cleansed air in a specific direction. This will be useful for eradicating pet odors, cooking odors, and anything else that tends to linger in one area. There are also dedicated haze and pollen modes.
