The TALLDU negative ion plug–in air purifier is designed to trap odor–causing particles in the air and neutralize them.
It’s inexpensive, comes with an AC power supply, and purifies a room up to 900 square feet. While it didn’t have better odor–eliminating power than other purifiers in our roundup, it did have the least expensive price.
If you’re looking for a budget purifier, this could be a good choice for you. It has a simple on/off button and a light that indicates when the purifier is working. You should be able to notice a difference in your air quality immediately after turning it on.
