HEPA and Radiation       

Let’s take a brief look at the history of HEPA filters?

HEPA air filters were first designed in the 1940's. The US government was conducting nuclear tests and using HEPA filters so it could prevent the spread of airborne radiation.

In the 1950s HEPA filters begin to be commercialized and they were used in other industries to filter the air.

Since then these filters have been continuously improved upon to be of higher efficiency.  If you hear of Nuclear grade HEPA its actually the same filter as our customers have in their Alen air purifier. Hepa filters are simply the best filters available.

HEPA Air Cleaner Filters Today

Today, Alen’s HEPA air cleaner filter is highly efficient. Any filter that can meet the same filtering standards by removing 99.97% of the particles in the air can be called a HEPA filter.


True HEPA air purifier filters are:

•    Very efficient at removing particles larger than 0.3 microns.
•    Efficient at removing particles larger than 0.01 microns

What is a HEPA filter? What does all this mean for you? Do you need a HEPA filter?

If you want cleaner air, clear of dust, bacteria, viruses, radiation, pollen if you have allergies, or have asthma then a HEPA filter as part of you air filtering system would be a very good idea.
