Most HEPA filters consist of interwoven glass fibers that are twisted in countless directions to make a fibrous maze.
Why Hepa filter is used
Straight Impaction: It has large contaminants, such as certain types of dust, and pollen, which travel in a straight path, collide with fiber and get stuck to it.
- Sieving: The air carries a particle between 2 fibers, but the particle is large than the gap, so it becomes attentive.
- The Interception: Airflow is quick enough to redirect around fibers, but particles endure on their path and stick to the sides.
- Good Diffusion: Small, particles move more unpredictably than larger ones, so they are more likely to stick to fibers.
Will small particles penetrate a HEPA filter?
There are other technologies that work in Hepa Air Filtration System to ward off small contaminants, such as smoke, and other chemicals. Activated carbon filters, use small pores to capture chemicals, odors, and smoke that a HEPA filter might not catch.
Where are Hepa Air Filtration System used?
Hepa Air Filtration System was originally intended to be used in the lab and many factory settings. Today, they have also made their way into customer products, including cars, and air purifiers.
What do the HEPA air filters do?
Hepa Air Filtration System removes tiny particles from dust, pollen, bacteria, and more from the air. Thin glass fibers are casually arranged into a dense, paper-like material that is gathered into pleats to make the filter. As air elements pass through these filters, the pollutants get trapped in the fibers. As large particles stick to the filter, they retain other small particles from passing through. A HEPA filter can trap elements very small as 0.3 microns. When placed into separation systems like air cleaners and purifiers, these HEPA filters can remove 99 percent of elements from the air. These filters were originally used in nuclear plants, but a host of innovative devices use this technology that can help to clean the air in your home.
Types of Hepa filters
There are many air filters and air cleaning devices available for home use. HEPA air filters can be used in cleaning devices, portable air cleaners, fan systems, and heating & cooling units. The goal is to sieve tiny particles from the air as it goes through these devices. HEPA filters are recognized as highly effective, sieving some of the small particles from the air. Other examples of Hepa filters include:
- Ultra-HEPA filters – These can trap up to 99.99 percent of elements of 0.3 microns or smaller.
- Electrostatic filter – These trap elements using a small static control, which helps the particles to stick to the filter.
- Electrostatic precipitator -These sieves use metal plates to attract particles with a reverse charge. They can be washed and can be reused.
- Ionization process – These filters trust on a small charge that emits a magnetic attraction to elements in the air. This filtration may release ozone gas and could cause some irritation for people who have respiratory diseases.
How to choose HEPA air purifiers
There are many options when it comes to home air cleaning, and the choices can become devastating. While the EPA does not recommend specific types of air filters, the intervention does offer advice for selecting the correct product for you.
The Size matters
Look for moveable filters designed for the room size where you are trying to use it. Generally, the clean air delivery rate of your filter should be equal to two-thirds of the area in the room.
Avoid the air cleaners that will generate ozone
Ozone is a gas that will be released during some air purification process. While ozone gas is meant for cleaning and sanitizing air, it is also considered a pollutant that can cause big irritation and damage to the lungs when it is gasped. Air cleaners that use ozone are usually intended for rooms that are unoccupied at the time of use. They are not for use in limited spaces when you are living.
Want the best Hepa air filtration system?
You can decrease your chances of degrading health caused by interior pollutants, which can also trigger respiratory infections, or aggravate asthma by installing a HEPA filter air purifier. You can purchase a good quality Hepa Air Filtration System from Earthstongue at a reasonable price.
