High concentrations of indoor pollutants can continue to last even after the source is gone. For example, if you burn food while cooking, the odor will last long even after you discard the food. This is also true with outdoor sources such as wildfire emissions.
If smoke gets inside your home, the odor will be present even after the fire dies down. To reduce the effect of pollutants in your home, you need a reliable air purifier. By placing the air purifier close to the source, the purifier will suck in the dirty air and release clean air.
If there is no specific pollutant source, you need to place the purifier where it can direct clean air to the occupants.

In-depth Review of Tredy Air Purifier:
Indoor air quality is more important today than ever. To ensure that the presence of pollutants such as pet dander, VOCs, smoke, and odors are no more, you need a top-quality air purifier. One of the best compact air purifiers on the market is the Tredy HEPA Air Purifier.
Here is why.
3 Stage Filtration System
We can see particles such as pet hair, pollen, and dust with our naked eyes. But there are ultrafine particles as small as 0.1 microns. These particles are so small and can enter our bloodstream via the lungs causing untold damage.
To prevent this and ensure you and your family breathe clean air, you need a purifier with a multi-stage filtration system. The Tredy HEPA Air Purifier has a 3 stage filtration system.
It has a pre-filter, medical-grade HEPA filter, activated carbon filter, and protective net filter. The first stage of the filtration system is the pre-filter. Located immediately behind the purifier’s intake, the pre-filter traps large particles that you can see with your naked eyes.
They include pet hair, furs, pet dander, and dust.
The second stage is the H13 HEPA filter. As one of the most powerful HEPA filters, the H13 is medical-grade quality. The H13 HEPA filter can capture 99.97% of all particles as small as 0.3 microns.
The H13 HEPA filter has a dense web of fibers, which ensures that even the smallest particles do not get through. Such particles include fine dust, mold spores, and tiny airborne allergens.
After the H13 HEPA filter, you have the activated carbon filter. Composed of granular carbon, the filter removes VOCs, smoke, and odor.
Lastly, we have a protective net. It helps to protect the fan.
What you need to know is that the filtration system comes as a single unit. All these filters allow 360-degree air filtration. If you use the air purifier normally, the filter will last for six months. To improve its performance, vacuum every two weeks.
The air purifier has a CADR of 100 cfm. It can filter a room of up to 200 square feet in 15 minutes. In an hour, the purifier can make four air changes.
Compact Design
The Tredy Air Purifier comes in a compact design. It measures 8.5 by 15 inches. Available in a cylindrical design, the air purifier weighs 6.4 pounds. As such, you can move it from room to room with ease.
Thanks to its compact design, it can fit perfectly on your nightstand, table, or work desk at home or the office. What we liked about the Tredy Air Purifier is that you can switch covers with or without legs.
With legs, you can place the air purifier on the floor, and you don’t have to worry about your pet knocking it down. Available in white, it has a built-in air quality sensor. The sensor detects pollutants in the surrounding air.
The sensors relay the information to the air purifier, which indicates the air quality level using one of the four-color codes. They include red, which means polluted, orange is bad, green is good, and blue is pure.
If the sensor detects polluted air, they automatically signal the air purifier. It selects the highest fan speed and allows the air purifier to suck in the unfiltered air passing it through the filters to remove the pollutants.

Noise Level and Other Smart Features
If you are looking for an air purifier that runs whisper-quiet even at the highest fan speed, then this for you. The Tredy HEPA Air Purifier has 3 fan speeds. At the lowest fan speed, the air purifier produces a noise level of 28dB.
This is lower than a normal conversation at 50 dB and the average home noise at 40dB. At 28 dB, the air purifier runs quieter than sources like soft music, whisper, or leaves rustling at 30dB.
As such, the purifier can run in your baby’s room all night without disrupting the baby’s sleep.
At the highest fan speed, the air purifier produces a noise level of 52 dB. This is slightly higher than a normal conversation at 50 dB.
The air purifier comes with a programmable timer. You can select 2, 4, and 8 hours preset shutoff. Besides the programmable timer, it has a standby night light mode. The air purifier has a two-level brightness.
To select the night light, shut off the air purifier, but make sure to stay plug-in. Press the AQ light once. This will allow you to enter the “Night Light” mode. Press the button again to change the brightness of the light.
