How does Jostart air ionizers work?
Jostart air ionizers release negative ions that actively attract airborne pollutants such as dust and pollen. This causes the charged particles to aggregate and settle to the ground, thereby purifying the air.
Where can I use it?
For optimal results, we recommend installing at least one Jostart unit in each high-traffic area such as bedrooms, living rooms, offices, dining rooms, and bathrooms to ensure continuous and efficient operation.
Does it make a sound?
This device features an ultra-quiet design, operating at a near-silent level. You’ll scarcely notice it’s there, enjoying only the presence of clean air without disturbance.
Is this product easy to use?
Unbox, plug in, and enjoy fresh air instantly! Featuring true plug-and-play design, you’ll feel the negative ion effect within 60 seconds of powering up. Compatible with any standard outlet, it creates a healthy breathing space anytime.
Why is black powder appearing around the equipment?
These are pollutants captured by negative ions from the air, primarily including smoke, kitchen grease, dust, and other particles. The carbon-based particles among them—especially those originating from soot and cooking fumes—appear black.
