In 1973, Ford began telling its own employees to use "an industrial type vacuum cleaner" to remove dust from brake drums.

Drained of power, Opportunity has not called home to Earth since, although NASA hopes winds on the planet will remove dust from its solar panels and allow its batteries to charge again.

Sailors scrub toilets, mop and buff floors, and remove dust from the web of overhead pipes, wires and vents along the ceilings of one of the newest ships in Japan's Maritime Self Defence Force (MSDF).

Some manufacturers claim filter standards such as "HEPA 4," without explaining the meaning behind them. This refers to their Minimum Efficiency Reporting Value (MERV) rating. These ratings are used to rate the ability of an air cleaner filter to remove dust from the air as it passes through the filter. MERV is a standard used to measure the overall efficiency of a filter.

Furthermore, vacuums can be used to remove dust from spacesuits. Mass spectrometry has been used to monitor spacecraft cabin air quality. The results obtained can then be used to assess the risks during spaceflight for example, by comparing the concentrations of VOCs with their SMACs. If the levels are too high then appropriate remedial action will be required to reduce the concentrations and the risks to health.

With a digital SLR, dust is difficult to avoid but is easy to rectify using a computer with image-editing software. Some digital SLRs have systems that remove dust from the sensor by vibrating or knocking it, sometimes in conjunction with software that remembers where dust is located and removes dust-affected pixels from images. Compact digital cameras are fitted with fixed lenses, which makes it harder for dust to get into the image area. Similar film cameras are often only light-tight and not environmentally sealed.

A method to prevent dust entering the chamber, by using a "dust cover" filter right behind the lens mount, was used by Sigma in its first DSLR, the Sigma SD9, in 2002. Olympus used a built-in sensor cleaning mechanism in its first DSLR that had a sensor exposed to air, the Olympus E-1, in 2003 (all previous models each had a non-interchangeable lens, preventing direct exposure of the sensor to outside environmental conditions). Several Canon DSLR cameras rely on dust reduction systems based on vibrating the sensor at ultrasonic frequencies to remove dust from the sensor.

As with the E-400 (in Europe only) and E-410 before it, the E-420 is notable for its portability, especially when coupled with the simultaneously released Olympus 25mm f2.8 pancake lens. In addition to being based on the inherently more compact Four- Thirds system, its diminutive size is achieved by the use of a substantially smaller right hand grip than found on most dSLRs (similar to the grip design used on the E-400 and E-410, but with an added "ridge" for comfort and stability), as well as the continued exclusion of Olympus' well-known sensor- shift image stabilization from the package. The E-420 uses Olympus' Supersonic Wave Filter to remove dust from the surface of the image sensor. The E-420 was announced in March 2008 to replace the E-410, and shipping started two months later.

A dust spot caused by a dust particle on the image sensor A dust reduction system, or dust removal system, is used in several makes of digital cameras to remove dust from the image sensor. Every time lenses are changed, dust may enter the camera body and settle on the image sensor. Digital single-lens reflex cameras (DSLR) are particularly vulnerable to this issue, since the interior of the camera is exposed during lens changes unlike other forms of digital cameras, and the image sensor is fixed, unlike a film camera. Even the tiniest (micrometre-size) dust particles or other contaminants that settle on the face of the image sensor (individual pixels of which have dimensions on the order of ~5 micrometres) may cast shadows and thus become visible in the final image as more or less diffuse grey blobs, depending on aperture.

Dust-Off was developed and introduced in 1970 by an employee at Falcon Safety Products who discovered that the pressurized blasts used to sound the alarm in the company’s signal horns could also remove dust from photography equipment and film without having to touch the surface. The Dust- Off compressed gas duster was first introduced to the photography market in 1970, and was marketed as a tool to blow foreign matter from photographic equipment and negatives that would not damage photographic prints during development. Due to the rise of personal computer use in the 1980s, Falcon developed Dust-Off II as a cleaning device to help rid damaging dust and lint from the new technology including screens, keyboards, CPU, and fans. Recently, the Dust-Off brand has expanded to encompass a line of cleaners for electronic and home office equipment, with a large number of products dedicated to cleaning smartphones, tablets, PDAs, HD monitors and TV screens.
