Air Filters That Are Precision Tested: Setting the Standard for Clean Air

At Koinfilter, we make quality air filters. We do this by testing our filters more rigorously. We use the MPPS (Most Penetrating Particle Size) tester, which is the best tool in the industry, to see how well our filters do against the hardest particles. This means our filters catch even the tiniest stuff, so you get air that’s as clean as it can be. We also use the air duct tester. This lets us test our filters in real-world conditions so we know they’ll work for you. We test our filters in an even harder way than the industry says we have to do.

Meeting Global Air Filtration Standards

At Koinfilter, we’re all about being the best we can be. We know how important it is to meet global standards so our filters not only work great, but also follow the best practices in the world.

EN779

The EN779 is the standard used in Europe to rate and classify general ventilation filters based on how well they work. Our filters meet the requirements of the EN779, so they do a great job of capturing particles, and they last a long time.

EN1822

The EN1822 is a European standard for HEPA filters that are used in places like hospitals and high-tech industries to capture really tiny particles. Our HEPA filters that meet the EN1822 standard are tested hard to make sure they catch even the smallest particles.

MERV

In North America, the MERV rating is the way they measure how good a filter is at catching particles. Our filters cover all MERV ratings, so they’re really good at cleaning the air in your house.

ISO

ISO is the group that sets standards for air filters all over the world. We follow their standards to show that we make good filters all the time and we’re always trying to make it better.

our vision & mission

Make the air cleaner

Creating greatness with our customers and making the environment healthier

We test our filters using the MPPS/DOP tester and the air duct tester, so we know they work really well in the real world.

How often you need to change your filter depends on how much you use it and what’s in the air. We usually say you should change your filter every 3-6 months to make sure it keeps working right. But, check the instructions that came with your filter to be sure.

Our team is here to help you! Talk to our expert and we’ll help you find the right filter for what you need.
