Hello
Would a double flow VMC equipped with HEPA filter be enough to purify the outside exhaust air (phyto product ...)?
For information :
For now I am equipped with a VMC simple flow, outside air comes directly into the house
http://fr.wikipedia.org/wiki/Filtre_HEPA
I found that :
A dust mask can not replace a respirator designed for pesticides. Be sure to use cartridges and pre-filters that protect against organic vapors. For more information on respirators, refer to the Pesticide Safety Course Manual developed by Ridgetown College, University of Guelph.
o Additional protective devices such as a filter cartridge gas mask or self-contained breathing apparatus may be required when applying:
+ a pesticide in an enclosed area
+ fumigants, gases, vapors or fumes
To work with fumigants, gases or vaporsor
to spray any pesticide in an enclosed area,
ALWAYS wear a respirator.

Research on air filtration
Your search for solutions to clean up the inside tunes interests me a lot.
The filter HEPA, it looks funny like that, but if it is manufactured only for personal breathing masks, you will have to change it every morning if you use it to filter all the air that enters at your home. What is the form of this kind of filter?

This type of filter is found on vacuum cleaners, at least those with several levels of filtration; it is indeed very effective but for pesticides, I do not know.
What is needed above all is that the air in your house is slightly overpressure compared to the outside (see topic on the working group Laigret) and therefore to have a filtered ventilation very powerful.
In other words today you have a VMC that puts the air of your home in depression; the air comes from outside by all the interstices, joinery not waterproof 100%, cracks in the masonry, ... etc. So the idea of a double flow VMC is good but it is necessary, in the absence of reaching a perfect watertightness (not conceived during the construction), to make sure to always have (or at least in period of agricultural treatments) a slight overpressure in your house; I do not know how you can get there with a double flow (maybe if there is less flow output than input?).

So
With a double flow having a beefier motor at the intake than at the suction it has to walk or playing on the regulators of flow in the pipes of aspirations and on the openings at the level of the windows.
Puree to quantify overpressure in housing not obvious (Indoor barometer type)
For filtering the outside air filter HEPA + activated carbon and this should be correct.
More creation of a house box for heat recovery in winter and more energy gain.
In any case it will be much better than the current stream.
Thank you

Hi fabio.gel
For the overpressure
and for 0 Euro, you tinker
(corrugated cardboard plastic packaging recovery)
https://www.econologie.com/forums/vmc-fabric ... t6023.html
It is necessary to synchronize the input and the output in volume
and return the warmed air,
to the ladle ... down (elsewhere?)
For outdoor air filtration
the activated carbon is "already" nanofiltrant
and has chemical reactions by Adsorption
but to be perfect on a target polish,
you need impregnated activated carbon
by a substance that neutralizes the target polishing product
(for the intant I do not have, nor make a link on the phyto)
To reduce the energy used for prefiltering,
we could design a prefiltering large particles,
with a maximum work surface,
like, a frame with a surface of 1m²,
large area that should facilitate the passage of air
with less energy consumption of ventilation.
it takes space
and something better than newsprint
as a filter ... if possible
(to find the recycle, very tight grains)
I forgot,
what does the moisture in a filter do?
the filtering would not it be blocked, if it was paper ???

And the plants then ...
The extra plants can be of great use.

Basically in the purification of the indoor air you have:
I'm on the negative ions but do not go to see the US sites, they date 1990 and it's scary;)
- Charcoal
HEPA (filters as in vacuum cleaners)
Negative ions
photocatalytic
