What can change from one model to another is the type of filter system that the device is equipped with.

HEPA filters are considered the top-quality filters you can have on an air purifier, even though they are also used for other devices, for example, vacuum cleaners.

And according to Smartairfilters, H13 HEPA filters can capture 99.97% of those particles above (and below) 0.3 microns and is considered medical-grade filter.

So in this article, we’ll go into every detail of H13 HEPA filters. Are they worth the money?

What Is A HEPA Filter?

HEPA Filter

HEPA stands for a high-efficiency particulate air filter. HEPA filters can trap 99.97 % of particles that are 0.3 microns in size. Can there be HEPA filters that trap a lower percentage than this?

No, because if they do not have the characteristics we’ve just described (being capable of trapping 99.97 % of particles that are 0.3 microns in size), filters can’t be called HEPA filters. 1

What Is The H13 HEPA Filter?

Now that you know what a HEPA filter is, you may be wondering what that H13 stands for.

H13 is a standard for HEPA filters that indicates that those filters can trap 99.95 percent of particles with a maximum size of 0.1 microns.

This makes H13 HEPA filters the highest tier when it comes to this type of technology. H13 filters are used in hospitals, clinics, and medical settings. 2

Are H13 Filters Worth It?

H13 Filters Worth It

Because they are the absolute best filters you can have on your air purifier, H13 HEPA filters are also the most expensive. Are they worth the expense?

Well, if you purchase an air purifier, maybe because you live in a particularly polluted city, you want your device to be as efficient as possible.

What’s the point of having an air purifier capable of trapping only some of the harmful particles that surrounds you? In this regard, H13 HEPA filters are totally worth it.

However, if you are low on a budget, you may not afford such an expensive device. In this case, what is the best alternative?

Well, these filters, in general, even if they don’t match the H13 standards, are still the most efficient you can find on air purifiers.

So, your choice should go in that direction. Then, you should also consider your needs.

For example, if you don’t live in a particularly polluted area, but you need to purify the air from bacteria (maybe because you work in or close to a laboratory), UV filters would be even more efficient than HEPA filters because UV light would kill them instead of trapping between the fibers of the filters.
