Sharp’s proprietary Plasmacluster Ion
(PCI) technology works by emitting balanced positive and negative ions into
indoor air.
These ions
neutralise airborne allergens, bacteria, mould spores, viruses, and
odours—leaving the environment cleaner and healthier.
Powerful
Dual Approach to Cleaner Air
1. True
HEPA Filtration for Asthma Triggers
Sharp’s air
purifiers use True HEPA filters that remove at least 99.97% of particles as
small as 0.3 µm, including
pollen, pet dander, mould spores, dust mites, and fine dust—common asthma triggers.
By
significantly reducing airborne allergens and particulate matter, the devices
help lessen airway inflammation and irritation, supporting clearer breathing.
2.
Plasmacluster Ion Technology for Added Respiratory Support
Sharp’s
signature Plasmacluster™ ions, emission of both positive and
negative ions, actively neutralise airborne microbes (e.g. bacteria, viruses,
mould) and allergens. These ions can also reduce odours and static in indoor
air.
Notably,
cellular-level research (Columbia University, October 2022) demonstrated that Plasmacluster
ions exposure decreased markers associated with highly‑viscous mucus—which makes
breathing harder—and increased
markers linked to low‑viscosity, smoother mucus,
potentially easing asthma symptoms tied to mucus hypersecretion.
Clinical
and Real-World Benefits
- Reduced allergens in living spaces helps lower inflammation
triggers, complementing standard asthma care.
- Ion treatment at cellular level may support healthier mucus
properties, easing airway obstruction
- Combined HEPA + Plasmacluster action may deliver better
outcomes than either alone, in terms of allergen reduction and microbial
suppression.

Why
It Matters
Model capacity should match your
room’s size (e.g. bedroom vs. living area).
Run
24/7 in key rooms to reduce allergen buildup and maintain low particle levels.
Replace
HEPA/carbon filters as advised (typically ~2 years,
some up to 5).
Place
purifier centrally, at breathing level and with good airflow.
Important
Notes & Limitations
These
purifiers are not medical devices and should not replace prescribed asthma
medications or doctor management plans
The
beneficial effects on mucus consistency have been observed in controlled cell
studies—not direct human trials with consumer units. Devices differ in ion
density from experimental setups (e.g. study used >50,000 ions/cm³ whereas
consumer units typically around 7,000–25,000).
Always
continue core asthma management—identifying/removing triggers, cleaning
bedding, vacuuming, maintaining humidity, and following medical advice.
Summary
Sharp’s air
purifiers combine True HEPA filtration and Plasmacluster Ion emission to reduce
airborne asthma triggers like dust mites, pollen, pet dander, mould, and
microbial particles.
Emerging
cellular research suggests potential mucus-related respiratory benefits. Units
such as Comfort FP‑J80J‑W,
FPK50UW, KC850U, and FXJ80UW offer tailored solutions depending on space size
and specific needs.
Used
consistently and maintained properly, these purifiers can serve as a valuable,
supportive piece in a broader asthma-management strategy tailored for indoor
air quality—for New Zealand households.
