HEPA is an acronym for High Efficiency Particulate Air and is basically a type of pleated mechanical air filter. They are best known for their ability to remove as much as 99.97% of mold, pollen, dust, and other airborne particles with a size of 0.3 microns. Needless to say, larger and smaller particles are trapped with an even higher efficiency, and this creates a contaminant free interior cabin.

If that in itself isn’t enough reason to shift to HEPA filters, premium HEPA filters by PUREFLOW have layers of activated charcoal that prevent harmful gases from entering the cabin along with antimicrobial technology to prevent the growth of mold, fungi and other potentially dangerous microorganisms.

Standard cabin air filters simply do not have the ability to match these numbers and cannot protect against gases like carbon monoxide, sulfur dioxide etc. This is why we highly recommend those living in cities with high levels of pollution to switch to HEPA cabin filter.

But having said that, HEPA filters end up trapping so many different types of contaminants over time that they need to be changed every 6 months to ensure they are working at their maximum capacity. If a cabin air filter gets clogged, you will start experiencing bad odors, poor cooling and heating from the HVAC system, increased noise from the blower motor, and in rare cases you might even see visible dust and debris entering the cabin. This obviously isn’t a comfortable environment to be in.

So the next time you’re questioning whether to have your car cabin filter replaced, keep in mind that it’s a simple process and takes less than 5 mins on most vehicles. It’s also important to remember that in today’s world, an advanced cabin air filter is a safety feature you really shouldn’t be driving without.
