Difference Between Deep pleated Hepa Filter and Mini pleated Hepa Filter

root — Wed, 10 Jul 2019 14:24:12 +0000

Mini pleated HEPA filter is quite different with deep pleated HEPA filter, HEPA filter is mainly used to capture dust particles of 0.5 um or below, it is composed of filter media and frame, different filter made of different material. HEPA filter with separator are called as deep pleated HEPA filter, another is mini pleated HEPA filter, which separated with wire like separator instead of ordinary separator.

1.Media

Deep Pleated HEPA filter media usually made of superfine fiber glass, which separated with paper or aluminum foil, frame can be heat resistant and made of wood, aluminum alloy, steel or stainless steel.Mini pleated HEPA filter media usually made of superfine fiber glass, which separated with hot-melt adhesive, frame can be aluminum and max 80 degree heat resistant, so it’s in lighter weight but weak heat resistance. Relatively speaking, mini pleated HEPA filter is better than pleated HEPA filter because of lighter weight, more compact structure and easier carrying.

2.Application

Deep pleated filter is mainly used for hospital, electronics, food, precision machinery, semiconductor production etc because of heat resistance.Mini-pleat HEPA filter is mainly used for high cleanliness required equipment and terminal outlets because of high efficiency, low resistance, large air volume, and small size.

What are HEPA and ULPA filters?

The High Efficiency Particulate Air (HEPA) mini-pleat filters that we supply are at least 99.99% efficient in removing particles 0.3 micron and larger (Grade H13 meeting ISO 6 clean room class). HEPA filters utilise spun-hooked glass fibre rolled into a paper-like material. This material is pleated to increase the fibre surface area and bonded, or potted, into a frame. Hot melt is used to hold the pleats far enough apart to allow air to flow between them. Ultra Low Penetration Air (ULPA) filters are at least 99.9995% efficient in removing particles 0.12 micron and larger (Grade U15 meeting ISO 4 & 5 clean room classes). Like HEPA filters, ULPA filters are made of spun-hooked glass fibre rolled into a paper-like material.
How long will a HEPA filter last?
A HEPA filter can last three to five years or more in a standard cleanroom environment. The life of the HEPA also depends on ambient conditions, the pressure drop across the clean room and maintenance of the pre-filters. Since airflow capacity decreases and static pressure increases over time, HEPA filters actually become more efficient as the filter loads. The filter should be changed once it has reached its capacity. For example, if a HEPA unit is set to 0.45 m/sec outlet velocity but is only achieving 0.35 m/sec, then the HEPA filter should be changed. Some manufacturing industries insist on changing filters every two years regardless of their condition.

How A High-Efficiency Air Filter Could Save Your Life

According to the Centers for Disease Control (CDC), PM is created from a variety of sources such as vehicle exhaust emissions, power plant emissions, coal-burning and wood stoves. (3) Long-term exposure to PM has been linked to eye irritation, difficulty breathing, lung cancer, and heart disease.
The new standard measures how well air filters trap PM10, PM2.5 and PM1 levels, so unlike previous standards, there are only three size ranges and three pollutants being measured.
The 10, 2.5 and 1 designations refer to the diameter of particulate matter in micrometers, and these three sizes are the most harmful because their microscopic size makes them easy to swallow or inhale.
“The new ISO 16890 standard is a game-changer for the air filtration industry,” stated Kevin Wood, Camfil USA Vice President Sales & Marketing. “Until this point, there had never been a global standard for high-efficiency air filters. Therefore, air filter consumers could not decide which filter was superior, because different countries were operating under different standards. With ISO 16890, consumers can make valid comparisons between air filters, especially since PM remains the biggest health threat to indoor air quality.”
Particulate Matter Prevention Methods
The fact that high-efficiency air filters are now being measured based on PM is important because these pollutants pose the biggest risk to human health.
Some of the PM prevention methods you can take include:
Checking the U.S. Environmental Protection Agency (EPA) Air Quality Index – this is a daily listing that tells you the air quality in your area, and how harmful it could be, especially to people with respiratory problems such as asthma.
Limit outdoor activities on days when PM levels are elevated.
Limit the time you spend on busy streets to lower your exposure to vehicle emissions
Invest in high-efficiency air filters using the ISO Standard to ensure you are removing the most harmful particles of concern.
