Koh HEPA JET - The Original and the Best.
Developed by a biomedical engineer and chemist, this is the ultimate bulb blower that ensures you blow only pure air into your sensitive equipment. Patents Pending.

Why take chances with conventional bulbs?
Conventional bulbs draw air directly from the environment with no filter. It's literally injecting concentrated air full of dust right onto your camera chamber. Dust accumulates in the sides of the chamber and eventually attaches to your sensor.

Protect Your Investment
You've spent hundreds if not thousands of dollars on your digital SLR camera. The eye of the camera is the sensor. Dust and humidity pose the greatest challenge to keeping the sensor clean. The Koh Hepa Jet Air blasts unwanted dust off the sensor without introducing dust or humidity into the camera chamber.  The replaceable HEPA filter removes humidity and 99.97% of air particles.  The HEPA Jet has an ergonomic Bulb that is comfortable and powerful.  Components are easily removable so they can be stored away easily inside gadget bags.
