What Does ISO 17025-Tested Filtration Mean?

One thing that makes PuroAir different is that its air filters are tested in a lab that contains ISO 17025 certification.

ISO 17025 Explained

ISO 17025 is a common rule. Many labs in the world use it for their testimonials. It is there to help show that they are better at testing things. It further also shows that the way they check things is correct.

If you want to buy, you should know that the claims about how well the filter works are tested, too. These tests actually take place in labs. The company is not the only one that checks this.

Independent lab tests can also show how well the filter system works. These tests are done in a careful way, so you can get good results.

Why Independent Testing Matters

When you think about ways to clean the air, tests done in a lab make you feel sure about them. This is specifically because they help to show:

  • Use the same testing methods every time
  • Build the performance results you can trust
  • Test things in a fair way for accurate results 
  • Follow testing rules that people all over the world know

It’s good to know that how well it works can be different for every different place. The size of the room, how air moves in it, the kind of airflow, and all other factors show how many times you clean or change the filter all matter.

How PuroAir’s Three-Layer Filtration Technology Works

Each purifier comes with its own special filter. This filter has several steps.Also, it should be noted that it  can catch many things in the air that may not be good for you.

Stage 1: Pre-Filter

The first layer that aims to catch big dirt pieces from the air. Further, It does this before the main filter gets them.

Some of the primary examples include:

  • Hair
  • Dust
  • Carpet fibers
  • Lint
  • All the bits you can see
  • Bigger bits from plants

If you take out the big pieces of debris first, then the  main filter will eventually last longer.

Stage 2: High-Performance Filtration

The second layer eventually catches a lot of tiny bits that float in the air.

The company states that this layer is made to help bring down:

  • Dust
  • Pet dander
  • Common things that cause allergy
  • Fine things in the air
  • Stuff from flowers
  • Smoke particles

It says that its filter was tested alone in a lab with an ISO 17025 certificate. And also that the filter can catch up to 99.9% of some very small things present in the air, down to 0.1 microns, when they test it. However, How well it does this may change based on the air around it and how you take care of the filter.

Stage 3: Activated Carbon Filtration

The last layer is specifically for gases and smells. Regular filters can not get rid of these by themselves.

Such an activated carbon layer is made to help lower:

  • Cooking odors
  • Smoke odors
  • Pet smells
  • Household odors
  • Some VOCs
  • Everyday indoor air irritants

By using these particle filters and tools that reduce such smells, the system tries to make indoor air feel good. It is, however, not just about the dust you see. But it also helps give you better air in your home.

Why Multi-Layer Filtration Matters

Each filter layer has a prominent job to do. When you bring all of these elements together, they work as one to make the air more clean in your space.

Filtration LayerPrimary FunctionExamples
Pre-FilterCaptures large particlesHair, dust, fibers
High-Performance FilterFilters microscopic airborne particlesAllergens, pollen, pet dander, dust
Activated Carbon FilterHelps reduce odors and certain gasesSmoke, cooking odors, VOCs

Using more than just one filter can help with many types of air problems that exist inside your home. This is actually better than using only one filter. It is good if the people in your house have different things they need to worry about when it comes to the air.
