Car ventilators for parked cars in open places have been around for years but it has always come at a cost -a terrible user experience. They have been always been poor-quality, inefficient, ready-made and insecure-until now.
acool is the first of its kind, addressing all the problems of current car ventilators. It is custom-made, secure and solar powered by design, using cross ventilation technology to reduce substantially your exposure to the adverse health effects of high temperature and pollutants in the parked cars.
¹Volatile organic compounds (VOCs) are pollutants that emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors, including parked cars (up to ten times higher) than outdoors.
Powered by a 50W solar panel, in module draws in cool and fresh outside air into the car through its 4 blower fans to blow hot air out of the car through the opposite out module. In just 5 minutes, this cross ventilation can replace all of the air in an average size car at least twice to optimize the cabin temperature.
acool is the first car ventilator to use cross ventilation technology, comprising in and out modules for effective air exchange. This speedy air exchange makes the cabin more comfortable when re-entering the car.
acool is designed and made according to the dimensions of each car's rear door window to ensure the right fit. No rubber strips and trimmings are required to seal the window gaps.
acool provides triple protections to help your car to stay securely closed while the ventilation does its work. It is strong enough to prevent anyone from being able to remove the unit or get into your car.
acool allows ventilation on hot but cloudy or even rainy days by providing a power option from your car's 12-volt power receptacle, which consumes a small amount of electricity from your car's battery.
acool is the first car ventilator to have an air filter. Dust and particles can be filtered so that only clean air is drawn in.
acool installation is straight forward and simple with a few steps completed in minutes. There is no drilling, no trimming of sealing strips, no tinting, and no alteration. And most conveniently, acool can be kept mounted while driving.
acool is the only effective solution to ventilate your parked car.
Every day, you have to live with heat and pollutants such as VOCs in your car. Even with a cool outside temperature of 24 °C, your car inside temperature can rise 10 °C within 10 minutes. And in an hour, the car inside temperature can be 25°C hotter than the outside temperature and VOCs can be 6 times higher. It is definitely harmful to you when you return to take a drive.
The glass windows of a parked car produce a greenhouse effect such that the solar radiation which enters the car is trapped inside, causing a sharp rise in the car cabin temperature.
High in-car temperatures accelerate the release of VOCs from interior finishes. The hotter the temperature, the more chemicals are released.
VOCs can cause serious health effects in both the short and long term. Health effects vary from minor eye, nose and throat irritations all the way to liver and kidney damage or cancer, depending on the level of exposure.
The UV rays and high temperature can damage and crack interiors including dashboard, steering wheels and car seats.
Rolling down the windows or running the air conditioner at high speed result in higher fuel consumption.

We created acool to address the problems of current ventilators to really benefit personal and family health and to raise public awareness of the issues around temperature problems in parked cars in open places.
Thanks to our team, we worked out the right solution.
At the successful end of the campaign, let us know the below information for your car. We will guarantee a customized acool. If there is no available acool for your car, we will provide an immediate refund: For example，
1. Make: Volkswagen
2. Model: Golf Mark 6 1.4TSl
4. Rear door window frame length (Red Line)
1. Wind down the rear windows on your car and attach in&out modules onto the windows. For automatic windows, steadily wind the window all the way up.
2.Mount the solar panel inside on the front windshield.
3. Connect the solar panel with the in- module.
4. Turn on acool by solar power. Green LED light is on.
5. Connect 12-volt power receptacle with the in-module for temporary use, if needed.
6. Turn on acool by receptacle power. Blue LED light is on.
201821697279- this product is designed to reduce the temperature and to maintain air exchange in parked cars. It provides cross ventilation to parked cars, with the in- module powered by a solar panel drawing cool and fresh outside air into the car through its 4 blower fans to blow hot air out of the car through the opposite out- module.
Most of our team members are everyday car users, suffering from the high heat and pollutants in our parked cars. Current car ventilators can’t help in reducing temperatures and with security problems. We have developed acool to redefine car ventilators, aiming to reduce temperature by over 15°C and VOCs concentrations more than 60% while maintaining car security.
1. Proof of concept and functionality
