What is UL std 900?
The UL 900 standard covers the requirements to determine the quantity of smoke generated and the combustibility of air filter units . The test is carried out on the unused filters, since the type of and level of particle loading greatly impacts flammability and smoke generation.
What is a Class 1 air filter?
Class 1 air filter units are described as “Those that, when clean, do not contribute fuel when attacked by flame and emit only negligible amounts of smoke.”
What is OEM air filter?
As their name suggests, OEM filters are original products that are manufactured and sold by the same company. Another, more recognizable term used to refer to OEM products is “factory original”. Aftermarket filters differ from OEM filters in that they are produced by third-party manufacturers.
Do I have to use OEM air filter?
Should I use a third-party air filter? Like oil filters, it is best to use the one made for your car by its manufacturer. OEM filters are specifically designed to suit your car. Don’t risk your car’s health by choosing cheaper alternatives.
Is it OK to use aftermarket air filters?
However, independent tests have found that these aftermarket filters may provide little or no performance benefit, and some types of reusable filtration units allow more dirt into the engine. That dirt will get into the engine oil, and the abrasive effects can damage internal engine parts.
What is an F9 air filter?
The F9 Synthetic Bag Filters are designed for use in HVAC systems and provides a higher level of efficiency and air filtration. This HVAC F9 Bag Filter is made up of microfibre synthetic filter media that is fixed into a galvanised metal frame.
What is the MERV scale?
MERV stands for Minimum Efficiency Reporting Value. MERV ratings are on a scale of one to 20 depending on the minimum size of the particles a filter can be expected to capture: A filter with a MERV rating of one to four captures particles greater than 10 micrometers.
What is F6 filter?
The EFS F6 Rigid Pocket Filter is designed to withstand extreme humidity and high velocities & turbulence, and is excellent for all types of air handling systems. Progressively structured design provides exceptionally low pressure drop at high efficiency levels.
What is the Merv scale?
What is the UL 900 standard?
The UL 900 standard is designed to determine combustibility and the amount of smoke generated for air filter units under test. Our equipment is constructed according to required methodology and simulates actual filter applications to determine accurate readings of performance and flame-exposure testing.
Are UL 900 air filters any good?
The UL 900 Standard has very good value for providing a level of safety between air filters that currently meet the class 2 level and air filters which cannot meet class 2, no matter if those filters are clean or dirty.
Why choose Intertek for UL 900 testing?
Intertek has applied decades of flammability testing experience with building materials for UL 900 testing. For the first time, filter manufacturers have a choice in independent testing partners for the UL 900 standard.
What are the requirements for UL 900 fire safety testing?
Then the product is tested in accordance with UL 900 and must meet the following requirements: No flame beyond the end of the test duct. Less than 25 sparks sustained beyond the end of the test duct. Less than 9 square inches of smoke measured below the smoke density time curve.
