Do you want to make the air in your building better? F7 bag filters are what you need. They catch the tiny bits of particles in the air, so the air is cleaner. Let’s find out what F7 bag filters are and why you want them.
F7 bag filters are air filters that do a really good job of catching tiny particles. The “F” in F7 stands for fine filtration. The “7” means the filter catches particles of a certain size. You’ll find these filters in HVAC systems. They’re key to keeping the air in your building clean.
Now, let’s look at F7 bag filters in more detail.
What is an F7 grade filter?
An F7 filter catches the smaller bits of stuff in the air. People often use it with a G4 filter to make sure the air is really clean. According to ISO 16890, the F7 filter is called ISO ePM1. It catches bits of particles that are 1 micron big.
EN779
An F7 filter is one of the filters you use to improve the air. It’s part of the EN779 standard, which says how good filters are. F7 filters catch tiny particles in the air. Those particles are usually between 0.3 and 1 micron in size.
An F7 filter catches smaller things in the air than M5 or M6 filters. F7 filters catch up to 85% of the particles 1um big in the air that go through them. That makes them really good for places where your air has to be really good, like hospitals, labs, and offices.
Use with G4 filter
People use F7 filters with G4 filters. The G4 filter catches bigger particles in the air as a pre-filter. That way, the F7 filter can catch smaller particles. That makes the F7 filter last longer and work better.
How they made
F7 bag filters are made with synthetic fibers that catch lots of dust in the air. They don’t stop the air from moving or slow down how good they are. That means the air stays good for a long time. F7 filters are made with a strong frame. You usually make the frame out of galvanized steel. That means the filter doesn’t break when the air pushes hard on it.
What is the difference between F7 and F8 filters?
F7 and F8 filters both catch tiny particles in the air. The difference is how well they catch stuff and how much they slow down the air. F7 filters catch stuff a little less well than F8 filters. But if you use an F8 filter, it slows down the air a lot. That can be a problem if you have an old HVAC system because it puts too much pressure on the fan motor.
How good they filter
F7 Filters: F7 filters catch 80-90% of the particles in the air that go through them, according to EN779. They catch particles that are usually between 0.3 and 1 micron in size.
F8 Filters: F8 filters remove 90-95% of particles in the same size range. This makes them great for places that need more clean air, like cleanrooms and special factories.
Pressure Drop:
F7 Filters: These filters have a moderate pressure drop, like 80 pa. This means they don’t slow down the air too much but still get the job done. That makes them good for lots of different HVAC systems. They don’t make the fan work too hard and make your energy bill go through the roof.
F8 Filters: F8 filters are better at catching stuff, so they slow down the air more than F7 filters, like 100Pa or more. This can be a problem in older or weaker HVAC systems. The slower air can make the fan work harder and use more energy. It can also mean you need to change the filter more often.
Which is better F7 or M5 filter?
If you want to know which filter is better for you, it depends on what you want. An M5 filter is fine if you want to improve the air. But if you want to make the air really good, especially for people with allergies, you want an F7 filter. F7 filters catch smaller stuff, so the air is cleaner.
What is the F7 filter for PM2.5?
F7 filters catch PM2.5. That’s the stuff in the air that’s smaller than 2.5 microns. It includes pollen, mold, fungus, bacteria, and viruses. Some F7 filters also have a carbon layer. That makes them better at catching bad stuff. They’re good for your places where the air has to be really good.
What Merv rating is F7?
F7 filters have a MERV rating of 13-14.
MERV 13-14 filters, like F7 filters, are good at catching 90% or more of stuff 3-10 microns big, 85% of things 1-3 microns, and up to 75% of particles that are 0.3-1 microns. This makes them great at getting rid of fine dust in the air.
What is the difference between G4 and F7 filters?
F7 filters are better than G4 filters because they catch more particles. G4 filters stop big particles, but F7 filters stop smaller things.
How good the filters are at catching dust
G4 filters are called coarse filters in EN779, and they catch about 80-90% of big particles around 10um or bigger. They’re good at catching things you can see, like pollen and fibers.
F7 filters are called fine filters; they catch about 80-90% of fine particles. They’re good at catching small things, like fine dust, mold spores, and other tiny things you can’t see.
Where they are used
G4 filters are not as good as F7 filters, so that you can use them first in HVAC systems. They catch big things, which helps the better filters last longer. G4 filters are good for homes, offices, and factories that need basic air cleaning.
F7 filters are more efficient, so people use them in places that need clean air. They’re great for schools, airports, and big buildings where you want the air to be clean.
Conclusion
So, F7 bag filters catch tiny bits of stuff in the air. That makes the air better for people. If you want to buy, use, or know about them, you want to know what they do. They’re good for any HVAC system. They make the air cleaner.
