What are G3 and G4 filters?

EMW® coarse dust filters are primarily used in turbomachinery air intake systems, ventilation and air conditioning systems, laboratories, chemical and pharmaceutical plants as well as in fume removal hoods at workplaces. EMW® coarse dust filters are available with plastic or metal frames.

What is filter grade G4?

A coarse G4 filter is designed to capture pollen, fog and coarse dust particles (≥10μm). It also captures leaves, insects, textile fibres, sand, ash, mist and hair.

What is G3 air filter?

G3 filter is suitable for the air conditioning system of the primary filter. G3 filter is suitable for the air conditioning system of the primary filter which is mainly used for filtering dust particles for more than 5 microns.

What is a F5 filter?

The EFS F5 Rigid Pocket Filter is constructed to withstand extreme humidity, high velocities, and high turbulence. This makes the filter excellent for all types of air handling systems. Self-supported filter pockets stay rigid in the air stream.

What MERV rating is best?

According to the ASHRAE, the best rating for residential HVAC systems is MERV 13. But before you upgrade your filter, make sure your specific system can accommodate that rating. A higher MERV rating often means lower airflow, which can cause the system to work harder—use more energy—to do its job.

WTW Filters vervangen. G3 voor G4 en F7 filters. Voor StorkAir WHR930, WHR950, WHR960.

Do higher MERV filters restrict airflow?

Wrong. While the highest MERV ratings are the most effective for air quality, they can harm your HVAC system. A higher MERV rating means a higher resistance, which means less airflow.

What MERV filter does carrier recommend?

Selecting a good quality filter with 12 – 16 MERV to remove a high percentage of offending particulates. Be sure to check your filter at a minimum of once per month.

Is MERV better than HEPA?

Here is where the HEPA (high efficiency particulate air) filter comes in. A HEPA filter is essentially the ultimate solution in the air filter world and far exceeds what a MERV 13 is able to do. All HEPA filters have a rating of a MERV 17 or higher.

What are F7 filters?

In a house where someone lives with a pollen allergy you can then choose to place a F7 filter. This is a filter that catches fine particles. The standard G3 or G4 filter will stop particles that you can still see with the naked eye but the finer structure of the F7 filter material holds O.A. Pollen and fine dust.

How do I choose an air filter?

Does it matter what kind of air filter I use?

The short answer is, no, they're not all the same. In fact, there are many different types of air filters available and choosing the right one can make a real difference in the lifespan of your HVAC system.

What are 30% filters?

For instance, a 30% filter (based on arrestance) means that 30% of the weight of the dust has been captured. Depending on the size of the dust particles the actual number of particles (and hence the percentage of particles) captured may be substantially less.

Are there different types of HEPA filters?

According to the Institute of Environmental Science and Technology, (IEST) with regard to performance, there are 6 types – A, B, C, D, E & F.

Do MERV 13 filters help with Covid?

What kind of filter should I use in my home HVAC system to help protect my family from COVID-19? Minimum Efficiency Reporting Values, or MERV, reports a filter's ability to capture particles. Filters with MERV-13 or higher ratings can trap smaller particles, including viruses.

Will MERV 13 damage my HVAC?

What Are MERV 13 Air Filters? MERV 13 air filters are the highest-rated air filters for home use. Any air filter with a rating higher than 13 will restrict air flow to the point of which could cause damage to your HVAC system, resulting in an added expense to fix it.

Is MERV 12 too high for HVAC?

When in doubt, choose a MERV 8 to MERV 10 filter rated for high airflow, so it won't damage your furnace or air handler. Or you can ask a certified HVAC technician what filter is best for your furnace or air handler.

What MERV is HEPA?

A HEPA is the creme de la creme of air filters with an equivalent rating of a MERV 17 or higher. A HEPA filter at a MERV 17 rating will trap 99.97% of air particles that are 0.3 microns in size, but capture an even higher percentage of particles smaller or larger than that size.

Is MERV 8 or 11 better?

A MERV 11 rated filter captures 85% or better of particles between the sizes of 0.3 and 10 microns. This may not seem like a significant difference compared to the MERV 8 filter, but a MERV 11 is also more capable of capturing between 65% and 79% of smaller particles.

Are expensive air filters worth it?

Yes, in general, the more expensive air filters are more effective, but a single person with no pets and allergies might not need as much filtration as a family of five with three pets and a child with asthma. Also consider how long your air filter will last.

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 a G2 filter?

G2 is a low-grade quality media that is suitable for general use in air conditioning filters, pre-filters in high-grade applications, and onsite temporary filtration media within construction areas. Medium : Polyester. Filter class according to EN 779:2012 : G2. Filter class according to ISO 16890 : ISO Coarse.

What is an F9 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.
