Design And Usability

TREDY TD-1500 weight
6.6 lb (3 kg)

TREDY TD-1500 has set a new bar on how to design an air purifier. This sleek modern looking exterior might not look very functional at first glance, believe me when I said there is more than meets the eye. At only 8.5 in diameters and 15 inches in height, it is bound for the bedside table, work desk, cabinet, or any tight area. The 6.6 lb weight also makes it easy for room-to-room purification when required. In most likelihood, TREDY TD-1500 is going to end up in the bedroom or living room. You can even place it in the garage, basement, kitchen if you find the need.

Moving to the functionality, TREDY TD-1500 HEPA air purifier comes with a standard 3 speed plus autonomous mode. With auto mode, the air machine will automatically set a higher fan speed when a high concentration level of pollutants is detected. Sleep mode locks the fan speed to low and dimmed down the indicator light. Additionally, a child-friendly Night light with 2 levels of brightness is available for added comfort and security. Then there are 2/ 4/ 8 preset hour timers that can be set to turn off the device after the interval time. Filter change light is pretty standard that reminds you to replace the cartridge when it is worn out. Finally, there’s an air quality indicator light that will display blue with pure air, green when air quality is still good, orange when air quality is normal, and red when air is polluted.

On the whole, TREDY 4-stage HEPA Air Purifier TD-1500 exceeded our expectations. Build quality is superb and the surrounding air inlet is excellent in drawing air pollutants. It is also Ul, ETC, AHAM listed, and certified ozone-free. The only downside is the 1-year warranty which is slightly less than some of its competitors’ 2 years offering.

TREDY TD-1500 comes with a complete 3 fan speeds with Auto and Sleep mode. Adding to that is the 200 square feet room coverage at 4 times the air refresh cycle per hour. For a non-asthmatic person or a person without hypersensitivity, you can boost the room size coverage to 400 square feet by dropping the air changes to 2 hourly. Highly impressive considering this is supposed to be a budget air purifier.

Official clean air delivery rate matches the airflow well at around 100 cfm for dust, pollen, and smoke. Our in-house test matches with the result with the exception of smoke that falls slightly short. While it does not hit our 200 cfm benchmark, the outcome is acceptable given it is an under 100 price category model.

Filters And Performance

Powering TREDY TD-1500 HEPA air purifier awesome air cleaning is the U.S. patented 360 degrees air filtration system. It captures harmful airborne particles at every angle, unlike some models that only draw from the sides. The outer pre-filter will capture dust, hair, fur, lint so it will not pass through to the HEPA filter. The main true HEPA filter will effectively trap 99.97% fine particles as small as 0.3 microns like dust mites, mold spores, pollen, pet dander, bacteria, and viruses. Lastly, the active carbon filter will remove cigarette smoke, pet odors, musty smell, and chemicals like VOCs, asbestos, radon. Something unique to TREDY, there is an additional protective net filter that captures any remaining particles in the filtration to ensure only clean, fresh air are released. Overall, we are happy with the grade of the filter but keep in mind that you will have to replace it every 6 to 8 months depending on the air quality condition.

Noise And Energy Usage

TREDY TD-1500 HEPA air purifier will run silently in the background with the right setting. By leaving it in auto or sleep mode, the noise output is at 28 dB similar to whispering noise. Perfect if you are going to place the air cleaner next to you while you work or sleep. Power consumption is low too even though we don't have the official numbers. After our long month of use with 24 hours of non-stop operation, we did not experience any surge in the electricity bills. A good sign of its energy efficiency.

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 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.

Very similar setup but with slightly better filtration performance and higher CADR. Lacks Auto mode and a protective net filter that can be a deal-breaker.
