What is a HEPA filter? I’m so Glad You Asked!

In case you haven’t noticed, at Crucial Vacuum we are pretty crazy about our HEPA filters. I suggest vacuuming with a good HEPA filter in nearly every post I write. But I have never really talked much about what a HEPA filter is. So, let’s talk about it!

What is HEPA?

HEPA stands for “high efficiency particulate arresting”. HEPA filters are air filter that trap almost all the dust and dirt particles down to and including 0.3 microns (AKA tiny particles of dirt and dust).

The way HEPA filters are made is what makes them more effective than other filters. They are made up of glass fibers, placed on top of one another, like pleats. These fibers are held together with the help of frames placed inside. Because the fibers are held so tightly together, it is nearly impossible for most contaminants to pass through. Therefore they become trapped inside the filter, instead of floating freely in your air.

Not just any filter can claim to be a HEPA filter either! The government has standards that a filter must meet before it can bear the HEPA name. In order to pass the test, filters must have the capability to trap at least 99.97% of .3 microns. That’s some serious trap-ability!

What are HEPA “like” Filters?

Long story short, HEPA “like” filters don’t meet the government standards for HEPA filters. A real HEPA filter will bear a government issued serial number. HEPA “like” filters are comparatively cheaper than HEPA filters, but in this case you definitely get what you pay for.

Why should you buy a HEPA Filter?

You’re probably already convinced, but just to remind you, HEPA filters are going to effectively trap the smallest toxic particles in your air. Vacuuming with a HEPA filter is one of the absolute best ways to ensure that you and your loved ones are breathing clean air. HEPA filters are especially beneficial for families with allergy and asthma sufferers.
