Review on 🚗 Upgrade Your Car Air Purifier with Medify MA-CAR - Advanced H13 HEPA Filter for Enhanced Purification, 99.9% Removal Rate, Modern Black Design by Jeremy Gulledge

Looking at a similar product, Scosche FreshAir, some notable disadvantages and advantages of this product can be identified. First the positives 1) it is very quiet. In the video, it makes almost no noise from low medium or high fan speed 2) large filter with large surface area, which is also easy to remove and replace with a new one 3) large air intake and large fan with more than twice the power. It runs at a maximum power of 12W compared to the maximum power of 5W for Scosche. Please note that the ionizer feature should definitely improve filtration in the smaller Scosche device. Negative1) Does not turn on automatically. This is a big minus and speaks strongly for the Scosche product. 2) There are no sensors. Unlike Scosche, which not only provides temperature and humidity, but also a particulate matter sensor that also automatically adjusts the fan speed when more particles are detected. 3) Questionable airflow design that completely bypasses the filter and negates all the benefits of the HEPA13 system. If you look at the exhaust vents, you can see that the motor is fully exposed to the cabin air from the top and sides of the unit, sucking air in rather than forcing it through a filter. In a low wattage installation like this unit, this essentially ensures that the air simply bypasses the filter and recirculates the air at the outlet. As with turbocharging (because this device uses a centrifugal fan), it's not airflow that matters, it's pressure. In this case, the small 12-watt motor cannot build up enough pressure to get through the filter and not vice versa. from the back of the device to see how open it is.
