Review on Trettitre Portable Purifier Sanitizer Eliminate by Jennifer Bernard

I am reviewing this product to answer my question that no one has answered (the previous question had an answer but it was unclear to me until I bought the product) and highlight other features of the product that others may want to know.1. LIFETIME OF THE UV LIGHT (answering my original question): As shown in my third published image in the product manual, unlike other UV air purifiers, this product has a built-in LED UV light with a lifespan of 10,000 hours. or about 3 years. Life. This means that the product can be used after this period of use if you do not agree with an air purifier without UV disinfection. However, most people like me who buy this product probably want a UV function and not just an air purifier with a filter. While this may sound bad, when you compare the prices of UV lamps ($10-$25) to the retail price of this product ($28.20 at the time of purchase), the one-time feature isn't bad. However, it is better to buy another brand with a replacement UV lamp if you have to pay full price ($79.99 at the time of purchase) or plan to use this air purifier for more than 3 years. PRODUCT PERFORMANCE: NO BATTERY (good to know): Unlike similar models, this one MUST be plugged in to work. It has NO battery and will NOT work without an external power supply. Since most products have lithium batteries with a limited charge cycle (they can only be charged and discharged a few times before they lose their ability to hold a charge, like your phone and computer), this product is unlike other disposable models in terms of battery life . The power cord (shown in my fifth picture posted) is just over 4 feet long, which is important to know as there is no battery power - your cord must be able to reach the charging port for the unit to work. Of course, you can purchase a USB extension cable separately if needed for your installation.3. CLEANING ABILITY (good to know): The device probably really cleans a small area with high power that's still pretty quiet. Low power can clean the car, but it will probably take a long time, if at all. Low power is very quiet.4. POWERING THE UNIT: CABLE SPECS (good to know): As with my first and fifth posted product images, the cable that came with the product goes into a small port on the air purifier and the other end of the cable is for a standard USB port. I'm not sure if the cable is reversible or if the full size USB connector on the product is intended for use with a USB to USB cable which is not included. Again, the cord is just over 4 ft.5 long. SIZE (good to know): In my fourth posted picture I compared the product to a pen so you can better understand the size of the product. this review. Hope this helped you make a decision.
