This is why I bought a HEPA vacuum cleaner Miele me some time ago.
HEPA vacuum cleaner filter even the smallest particles, such as dust mite feces and mold spores from the air. Thus, the air comes out clean at the outlet, as it was drawn in front.
For this reason, HEPA vacuum cleaners be applied to the mold remediation because the spores of less than five thousandths of a millimeter can be large and therefore are respirable.
Who itself is allergic and uses a conventional vacuum cleaner, is when using a Hepa vacuum cleaner notice the difference immediately in a pleasant way.
So, buy and suffer less!
