Why do washable HEPA vacumn filters make such a big difference?

[Guest guest]

It seems to me that the " cleanstream " style HEPA filters that allow

you to wash them out make a huge difference to sensitive people even

over non-washable HEPA filters that on paper, let fewer particles

through.

My theory is that even the microscopic particles from one encounter

with a very bad mold can make a HEPA filter toxic for the sensitized -

the tiny fungal fragments..

What do you think about this, Carl, does this agree with what your

clients were saying?

Its a powerful argument for the washable HEPA filters...
