Two listings carry the same 6-inch waterproof electric exhaust fan, but the listed prices are different. If you're shopping for a ventilation ducting air distribution setup, the decision comes down to whether you pay the lower or higher listed price for what appears to be the same product.
Quick verdict
If you're choosing between these two, the fastest decision is to look at the price. Both listings describe the same 6-inch waterproof electric exhaust fan with identical attributes, so the listing at the lower end of the price spread gives you the same feature set for a smaller outlay.

Where each listing wins
The lower-priced listing wins on the only measurable difference: the listed price. The higher-priced listing matches it on every attribute but doesn't add any extra feature you can see in the listing details. For ventilation ducting air distribution, both have the same 6-inch size, 115W power, and 3150RPM speed, so the functional characteristics are identical.
Product notes
Waterproof Electric Exhaust Fan, Duct Fan Ventilation Equipment, 6" Exhaust Fan - USD 126.68

This is the lower-priced of the two identical listings. It's a white, round exhaust fan with a 31*30cm size, 115W power, and 3150RPM speed. The construction mixes ABS and stainless steel, and it's positioned as a portable drum blower fan for ventilation ducting air distribution. The listed description points to high-efficiency airflow and powerful wind force with a focus on low-noise operation. The concrete reason to choose this listing is the lower listed price. The limitation is that it offers no functional advantage over the higher-priced listing, because the specifications are identical.

This listing carries the same product name and the same attributes: white ABS and stainless steel construction, 115W power, 31*30cm product size, round shape, and 3150RPM speed. The description also emphasizes high-efficiency airflow, strong wind, and low-noise operation. The concrete reason to consider this listing is that it carries the same complete set of attributes, so it will deliver the same results in a ventilation ducting air distribution setup. The limitation is that it costs more than the identical lower-priced listing.
Final choice by use case
If you want a 6-inch waterproof electric exhaust fan with a round white design, 115W power, and 3150RPM speed, and you want to minimize the cost, choose the listing at the lower end of the price spread. If you have a reason to favor the higher-priced listing, the listed details don't set it apart, so the decision remains price-driven.
