(Why don't we show the price?)

Retailers have the legal right to set their own prices, but some manufacturers place restrictions on how those prices may be communicated. Because our price on this item is lower than the manufacturer's “minimum advertised price,” the manufacturer does not allow us to show you our price until you place the item in your cart, or in some cases, proceeding to the final checkout stage. Taking these steps allows Appliances Connection to show you our price consistent with our goal of always offering you the lowest possible prices on the widest selection of products. You are not required to purchase the product to see our lowest price, simply just remove it from your cart.

Sharp Air Purifier with Plasmacluster® Ion Technology
The Sharp Plasmacluster Ion Air Purifier with True HEPA Filtration effectively reduces pollen, dust, pet dander, smoke, germs, bacteria, viruses, odors, mold, and fungus in your living space. There is a dual stage filter system including an activated carbon filter and long-life True HEPA filter, which captures 99.97% of particles as small as 0.3 microns from the air that passes through it. Patented Plasmacluster Ion Technology disperses positively and negatively charged ions throughout the room to safely break down microorganisms and odors (even those trapped in fabric, carpeting, and drapery!). It is an ideal solution for allergy sufferers, asthmatics, pet owners, and smokers, and best used in a bedroom, living room, study, or exercise room. There are 3 manual fan speeds. The unit has LibraryQuiet™ operation (as quiet as 29 decibels, or the sound of rustling leaves) and is ENERGY STAR® rated, so you can run the unit continuously while saving money and energy.

Naturally Advanced Technology for Truly Clean Air
Sharp’s exclusive patented Plasmacluster® ion technology eliminates microscopic pollutants that traditional filters cannot trap, by replicating nature’s own cleaning process of producing positive and negative ions from water vapor in the air. These ions refresh the air without any harmful chemicals or perfumes.

Almost Perfect Allergen Removal
True HEPA filtration is ideal for removing common household allergens such as dust, pollen, pet dander, and smoke from the air. With True HEPA filtration, which removes 99.97% of airborne pollutants as small as 0.3 microns, including dust, pollen, pet dander, and smoke particles, more particles can be captured when compared to a HEPA-type filter.

Automatically Detects, Displays and Reacts
Built-in temperature, dust, and humidity sensors monitor your air quality and automatically clean and humidify as needed, so you can sit back and enjoy healthier, fresher air!

Reliever Dry Air Symptoms
Humidifiers can help relieve sinus issues, dry throat, dry eyes, and chapped lips. They can also help relieve dry skin caused by psoriasis, thyroid disorders, topical medications, and cosmetics. Heaters used in wintertime can also lower the humidity level in the air, so having a humidifier is helpful.
