HEPA filters are simple, mechanical filters that remove particulate including dust, pollen, mold spores, and dust mites from the air. While different HEPA filters have different designs which vary in working efficiency. Well-designed HEPA will remove 99.97% of particles that are 0.3 microns or larger from the air. Here we mainly talk about how to design HEPA.
It is important to realize that not all HEPA filters are designed well. Not all air purifiers that are advertised as HEPA filters are equally effective. Consumers must be vigilant when purchasing HEPA filters, as un-certified filters can have significantly poorer results. Let's return to our subject- how to design HEPA.
First and foremost, HEPA filter should be designed with convenient operation, including the installation, usage and maintenance. As the air quality is decreasing, many people prefer to use a HEPA filter to clean air. When design HEPA filter, modular ideas can be used in the installation progress. Most machine need maintenance, HEPA filter is in no exception. Proper maintenance can prolong its lifespan, so the maintenance should be designed convenient as well.
About how to design HEPA, a thoughtful working principle should be taken into consideration. Generally speaking, a fan blows air through a high tech filter, trapping particles as they pass through. A common sense but important point to remember is that air must pass through the HEPA Air Purifier filter in order to be cleaned. Air bypassing the filter will not be cleaned. This technology is categorized as Passive.
Last but not least, HEPA filter should be designed with high working efficiency. Most HEPA filter can remove close 99% of unwanted elements that is not done by any other filter machine. This is possible because of the mat in filter. It does not recirculate the polluted air like done by normal vacuum cleaner. Compartment where the filter is contained can be removed from the air purifier unit and either sprayed down or submerged into soapy water. Being able to clean the HEPA filter is an advantage to users because they are then washing away the very irritants that cause their allergies to become irritated.
All these information above are essential factors that good Filter manufacturers should bury in mind. You can learn more information on www.hefilter.com. Shanghai Hefilter is a famous filtration manufacturer who specialized in manufacturing high-quality filters for many years.
