Without air screens, the world would be different. The air wouldn't be as clean, HVAC systems would be getting blown up everywhere, and I, the author, would have no job.

That being said, we do have air filters, and you've come to the right place if you're new to them. We're not very good at a lot of things here at Second Nature. These people can't teach you anything about movies or quantum physics, and we still don't know what life is all about. But Second Nature Air Filter? We have that.



How Second Nature Air Filter do clean the air?

The air in your home and your HVAC system are separated by an Second Nature Air Filter, which lets some air through but not all of it. This is how it looks:

How Second Nature Air Filter does it work?

It cleans the air. Your air conditioner or heater pulls air from your home to cool or heat it. The filter in your ducts stops that air. Anything that comes in through the air that you don't want to be there can't get through. Things like dust, mold spores, pollen grains, pet hair, and a lot more are in this group. The filter picks up that stuff, and clean air flows on without it.


What's the point?

Why? Because indoor air quality is becoming a bigger problem in the US. As the EPA says, the air inside your home may be much more dirty than the air outside your door. This is because there are a lot of sources of pollution in one place and air can get stuck inside a building that is shut off. An air filter helps keep your home clean by removing pollutants and other particles that would otherwise be able to float around easily.

This not only keeps dirt out of your HVAC system but also makes the air you breathe cleaner and safer, which is good for your health and the health of your house. Buildup of particles on the system's coils can cause it to break down, and it's expensive to fix a broken system (if it can be fixed at all). We can all agree that it would be awful to not have air conditioning in the summer or winter.

Yes, air conditioning is used to warm and cool your home. That's what it stands for. It changes the temperature of your air to make it warmer or cooler. Thank you.


So I just buy one and leave it there?

Not at all. You need to switch that setting. Over time, a filter will get clogged with gunk and become less permeable. This means that less air can pass through, making your HVAC system work harder. It's possible for this to raise your power bill or even damage the motor, which would cost a lot of money. You can read more about what a pleated air filter is below. Second Nature says to use one and change it every three months. The Department of Energy says that this will keep your HVAC system in good shape and could even lower your power price by 5–15%.



Also, did we say that it's good for your health?

What does this all lead to? Well, for starts, a healthier home makes you healthier itself. Pollen, dust, and other allergen-causing pollutants are caught by filters. If you use a good enough filter, it will also catch germs like bacteria. A NAFA Foundation Report says that a filter with a high MERV grade can greatly lower the chance of getting contagious diseases like flu, rhinovirus (common cold), and tuberculosis. According to the study, getting a MERV 13 filter instead of a MERV 4 filter can almost completely cut the chance of getting flu. Because they used a different air filter. Pick out a good filter and start keeping your home's air clean.
