What is a Fan Filter Unit ?

A fan filter unit, or FFU, is essentially a filtered laminar flow diffuser with an integrated fan and motor. The integrated fan and motor provide enough static pressure to overcome the pressure drop of the internally mounted HEPA or ULPA filter.

What is a HEPA Filter?

A HEPA filter is a high efficiency air particulate air filter that can capture ultrafine pollutants. HEPA filters are considered the industry standard for removing dust, pollen, mold, bacteria, particulate matter, and other airborne particles. A HEPA filter is found in air purifiers and forced-air HVAC systems. There are two common standards for HEPA filters: European and U.S. In Europe, HEPA filters must remove 99.95% (ISO) of particles that are 0.3 microns in size. In the U.S., HEPA filters must remove 99.97% of particles that are 0.3 microns in size.

What is a Pre-Filter?

A pre-filter is an air filter that removes large particles like dust, dirt, and hair. Pre-filters are the first step in the air filtration process on an air purifier. A pre-filter protects the main air filters from getting clogged up with debris so they can trap microscopic pollutants.

What Is a HEPA Filter and How Does It Work?

A high efficiency particulate air (HEPA) filter can remove 99.97% - 99.99% of airborne particles that are equal to or larger than 0.3 microns in size. The efficiency is rated based on the worst level possible, so think about it as 99.97% or BETTER. The filters are tested using air particles that are 0.3 micron size as those are the most difficult size for a HEPA filter to catch. HEPA filters are actually more efficient at capturing smaller particles, like those the size of viruses

What Are the Differences between a MERV 13 and a HEPA Filter?

With most people looking for better ways to protect themselves against potential airborne transmission of COVID-19, many products on the market are being promoted as effective devices to implement in their residences and businesses. One major step towards reducing the risk of COVID-19 noted by many health safety organizations would be the upgrade of the building’s air filter to one that is rated at a MERV 13 level or higher.

5 Facts You Need to Know to Pick the Best Air Filter

Many people treat the choice of an air filter for their homes like an afterthought. In some other cases, we have seen many go multiple months without even checking on their filters, talkless of making a move to change them. If you happen to fall into any of the above categories, you are doing yourself more harm than good

The Value Of Cleanrooms For Semiconductor Applications

Semiconductors are a vital component of almost every electronic item we rely on in a modern world: cell phones, vehicles, microwaves, computers, televisions — the list goes on. When there are shortages due to a lack of materials or slow production, that delay is felt up the supply chain by every consumer who is buying a new phone or computer, or even renting a vehicle.

What Is a HEPA Filter, and Why Is It Effective Against COVID-19?

There’s a lot to talk about when it comes to HEPA filters – short for high-efficiency particulate air filters – especially when seeking a sound solution to improve indoor air quality. The hefty HEPA has earned bragging rights, offering top-of-the-line protection when it comes to capturing a majority of tiny airborne contaminants and keeping occupants safe in an indoor pocket of space.

The Definitive Air Filter Guide

With lingering air quality problems both inside and out, many people are turning to air purifiers to create healthier, cleaner air in the home. These air purifiers use numerous technologies and have many different components.
