Dust, mites, pollen – our houses are full of microscopic pollutants that cannot be seen with the naked eye. An ordinary vacuum cleaner often only mixes them in the air, instead of effectively removing. This is why HEPA filters were created to deal with even the smallest particles.
Where did HEPA filters come from?
This technology was not created for home cleaning. NASA developed it in the 1940s to protect employees against harmful molecules. Over time, she went to the pharmaceutical industry, and from there to our homes. Today it is a standard in equipment for allergy sufferers.
How does it work?
The HEPA filter is an advanced system made of thin fibers microskla or synthetic materialsarranged in a characteristic harmonica. This design provides a huge filter surface, despite the small size of the filter itself.
Not every HEPA filter is the same. On the market we will find several classes, from E10 to H14. For allergy sufferers, the most important are those marked as H13 and H14 – can catch ≥99.95% and ≥99.995% of the smallest pollutants, respectively. This is a huge difference compared to the basic filters that pass much more particles.
Watchable or indelible?
On the market you will find two types of HEPA filters. The first are washable filters – They are stiff and rough to the touch. We can wash them and use them for a very long time, as long as we follow the manufacturer’s recommendations regarding maintenance. The second is indelible filtersmade of cellulose. They look like smooth, thin paper. They wear out much faster – then they must be replaced with new ones.
Who is the Hepa filter most useful for?
First of all for allergy sufferers and asthmatics. These filters are great at mites, pollen and other allergens. People with small children or pets owners will also appreciate them. Hepa effectively catches hair and other minor impurities.
Let us remember, however, that even the best HEPA filter will lose its effectiveness, If we don’t take care of him. Washable must be rinsed regularly, and one -time replacement according to the manufacturer’s recommendations.
HEPA vacuum cleaners are more expensive than ordinary models. However, if we have an allergy at home or we just care about really clean air, it is worth considering this investment. This is not only cleaner air, but also less dust settling on furniture after cleaning.
