What is a HEPA filter and how does it work?

High-Efficiency Particulate Air filter also referred to as HEPA filter can be regarded as a mechanical air filter that effectively and efficiently removes even the smallest dust particles, bacteria, and pet dander from the air. HEPA filters are widely used in different types of vacuum cleaners, air purifiers, and diverse industrial applications to remove the smallest particles from the air by passing indoor air under pressure through a mesh of randomly arranged fibers made of fiberglass.
To make the optimal use of HEPA filters you should know how to clean a non-washable HEPA filter in vacuum cleaners accurately else the very purpose of using it wont be served.
To maximize the particle-capturing ability and add to the surface area, HEPA filters are folded into pleats. One of the advantages of HEPA filters is that they do not emit ozone gas as a byproduct.
HEPA filter works by the primary mechanism of mechanical filtration. By forcibly passing air through the dense network of fibers, HEPA filters physically trap the particulate matter by the mechanisms of impaction, interception, and diffusion. The air passing through the mesh of fibers is also forced to change its direction while moving through the fiber network to effectively trap the particulate matter.
What is HEPA filter used for?
HEPA filters are widely used in different settings to improve indoor air quality by trapping different types of smallest airborne particles to take care of our respiratory health. Preventing dust, dirt, pollens, and allergens from getting released back into the air during the vacuum cleaning session, HEPA filters keep respiratory issues like asthma and dust allergies at bay.
What is the difference between a HEPA filter and a filter?
A filter can be categorized broadly to include different types of devices known to purify air or liquid from impurities and particulate matter. On the other hand, a High-Efficiency Particulate Air Filter or HEPA filter is a particularly designed filter to trap even the smallest particles from indoor air to ensure a healthy breathing environment.
Although both filters have proven their efficiency in purifying indoor air by removing pollutants and allergens, HEPA filters are much more effectively designed to remove particulate matter as small as 0.3 microns with high precision and optimal performance. To put HEPA filters to their maximum use you should know how to clean a non-washable HEPA filters in vacuum cleaners in the step-by-step format.
Is HEPA filter good for health?

HEPA filters have proved their expertise in trapping particles as small as 0.3 microns contributing to purified indoor air and a healthy environment that ensures your respiratory well-being. By improving indoor air quality via HEPA filtration, you can considerably mitigate the risks of developing respiratory infections while also keeping your dust allergies and asthma at bay.
HEPA filters are predominantly seen in urban homes having toddlers and pets where a lot of pollutants and allergens are present in the indoor air. Proper use abiding by manufacturer guidelines, and regular and thorough maintenance should be in place so that you receive the optimal benefits of HEPA filtration.
How to Clean a Non-Washable HEPA Filter in Vacuum Cleaners-Step-by-Step Guide
