To whom it may concern,
I have had the venturi ventilator installed in the apartments at the Mott Haven Housing units and confirm that the vent performs admirably. The mold and mildew problems that we were experiencing have cleared up and the air quality has improved to the point that the tenants no longer have any complaints about the mustiness or mold.
The installation was quick and easy, and to my knowledge, there is no product at any price that can perform its function as effectively.
We intend on installing the Thinking Venturi Ventilator in all or most of the apartments in our complex, and highly recommend this product to anyone who is interested in combatting mold, mildew, bad air quality, and complaining tenants.
Yours truly, 
J. Dorgan,
Superintendent

To whom it may concern,
We have installed the THINKING VENTURI VENTILATOR into our apartments. We are very pleased with the results of said product and would like to go on record that the VENTURI performs to our satisfaction as described, namely:
I. The apartment windows in which the venturi was installed are bone dry.
2. The condensation which was apparent on the windows prior to the installation of these venturis has disappeared completely.
3. The air quality of the apartments has improved so much so that each apartment dweller has stated that they are breathing and/or sleeping better, which means that the odors from day to day living are being expelled without direct infiltration of outside air.
4. Mold and mildew which were a constant problem in the apartments has not returned, and the mold that was previously present has become inactive and dry.
5. The venturi is maintenance free and we, the Superintendent's office, do not have to adjust or bother with product.
6. The installation is quick and easy.
7. We have no fear about tampering or vandalism in the apartments since the windows are always closed.
We invite all those who are interested in seeing the apartments to our complex, and would be glad to put our name among the endorsers of the product.
Very truly yours, 
Fred Hecker
Superintendent, Brownsville Houses

I’m so elated with my new Aura Solar Ventilators!!!!!
Please post this on you site so other misguided consumers can have a real view of these wonderful new vents. It really works!!! These were just installed right before the gas hikes, so the summer time will be trickier to gauge, but definitely this winter, I see the difference. I’ve NOT had to put my heater on at all!!!! My temperature remained at 69.7 through these cold spells, and we’ve even had snow here in Louisiana, and that’s cold for us.
Whatever I can do to save utility costs without spending an arm and a leg, are the areas, I’m looking for, and this was a great decision for me. I bought 4 of these for my roof, and my living square footage is around 2000 sq. ft. You know the ole saying, “You got to spend money to save money”, well, at least, it’s not your arm and a leg, and I feel it probably has already paid for itself!!!
Before, I had those horrible “whirly-bird turbines” and couldn’t understand why my bills were so high. The “whirly-bird turbines”, works backwards….They don’t spin in the summer and spin in the winter, I call this system a “Backward System”!!!!! I even called our La. Source for saving energy, and this guy even told me, they didn’t believe in the ventilators!!!! I guess not, because he would be out of a job!!!! I’m glad I used my own gut instinct on this one!!!! DO YOURSELF A FAVOR, cause I’ve already done myself a favor….I’m gonna save money!!!!!!!

Your Aura Ventilators have significantly lowered the upstairs temperatures in our house since they were installed at the beginning of this summer!
As I promised some months back, I gave several of the brochures you sent to the roofer who installed our ventilators [and I told his boss and also his foreman earlier, that those crappy 8" flat vents they put in roofs simply don't do the job]; as promised, I gave the rest of the brochures this morning to a neighbor who has three of those 8 inch flat vents in his roof, and who says that even with a ceiling fan and another fan blowing on him at night, he's still "miserable" trying to sleep. He will share those brochures with the contractor who is starting to build his new deck today. Anyway, you have a fine product and I'm happy to spread the word.
Sincerely,

P.S. We have had some monsoonal rains this summer (40-60 mph winds, etc.), and nary a drip from those ventilators.

We have had a 17'x10' cabin in the garden now for 9 years, purpose built to house a hot tub with a shower and toilet. It was built as a solid garden room with double glazing, underfloor heating and insulated double thickness roof and walls, but it soon became clear that it was too well insulated and we were having condensation problems, even when the hot tub wasn't on.
We had fitted an extractor fan from the outset but it could not cope. We added extra ventilation grills on the walls, and it was still bad, getting much worse when we had to turn off the underfloor heating as it was too expensive to run. The whole dynamics changed, exacerbated by felling the conifer trees that previously shaded the building from the sun for most of the day.
It was "raining" condensation from the roof, even after we installed a dehumidifier as high up on the wall as we could get it. The apex was still dripping water and the tongue and groove boards were popping out.
Having decided we needed a wind turbine vent I started looking around and found that they are not around over here, so followed Google to the US where I found the Aura Vents. I spoke to Martin several times on the phone about the best sizes and he was very helpful but a little unsure that the vent would be able to deal with the steam from the hot tub.
We eventually bought a 12" telescopic vent for the cabin, and added a 6" vent for the shed, which also suffered from being unventilated and got very stuffy and musty smelling. A neighbour who is a carpenter fitted them both easily and repaired the ceiling at the same time. We trimmed the flange on the large vent to look a little like a porthole so that it was more decorative.
I have to say that cutting a 12" hole in the roof was a little scary but I wish we had known about these vents 9 years ago as it has cured all the problems with no leaks! We have now disconnected the fan and sold the dehumidifier on eBay, and the cabin is well aired with no condensation, whatever the temperature outside.
When the hot tub is on, there has always been an inversion layer of steam which used to take a long while to clear but now it disperses very quickly and the room stays dry. Even the shower curtain now dries out properly instead of "stewing" and going mouldy.
We are so impressed with these vents, and the problems we had have been cured for a very small outlay, plus the electricity bill has gone down sharply. We would thoroughly recommend them, especially for dealing with hot tub enclosures.
