The w-pro condenser is still useful! it is on to find the two type of dryer that exists evacuation or condensation, you should know that evacuation dryer have nothing to do in a kitchen or even bathroom, but ultimately a laundry room where an external evacuation is planned, or simply in the garage, which is my case! For every product dryer moisture, except those in the condensation collected in a tank, unlike where the dryer vent simply rejected this moisture in the air of the room where it finds the dryer, either for myself the garage, but in another room that moisture can be very "painful" (mold ceiling, wall, etc.) Going back to the product it is most useful to retrieve the "dust" produced by drying laundry, as moisture / hot steam itself is just so cool diminished but still present! So nothing miraculous, but useful all the same! You still have to clarify that the "pack" includes plastic box + recovery hose (diam 102) to connect the dryer and the box + a tightening strap to attach the hose! So for the good complementary product price dryer to vent that is in a suitable piece !! If not for delivery still nothing wrong time perfectly respected by amazon.
