Another highlight of TREDY TD-1500 is the low-entry price. For less than 100 dollars inclusive of filters, it is the most bang for the buck HEPA air purifier in the market. Autonomous mode, sensor, nightlight, timer, and 4 standalone filters all come standard in the package. Even the replacement filters will not cost more than 60 annually on everyday use. Sure there are far cheaper options out there, but if you want a decent performance air purifier at a reasonable price, TREDY TD-1500 will deliver just that.
If you are residing in the U.S. or Canada, the best place to buy TREDY TD-1500 is via Amazon. It offers free shipping, 30-days satisfaction guarantee with plenty of stock availability. Other countries can try purchasing it from the Trendy official website that offers a similar package as Amazon minus the hassle-free experience. Retailers like Walmart, Target, Home Depot do not carry the brand for now so Amazon is still your best bet.

TREDY TD-1500 VS the challengers

PARTU BS-03 True HEPA Air Purifier


Very similar setup but with slightly better filtration performance and higher CADR. Lacks Auto mode and protective net filter that can be a deal-breaker.
LEVOIT Core 300 True HEPA Air Purifier

LEVOIT Core 300

Black housing with cheaper price tag and support essential oil fragrance addon. Other than that, it is an inferior product compared to TREDY TD-1500.
