Generally, you can increase the efficiency of the air purifier by up to 20% if you correctly place it. If you put the purifier in a corner or behind a television, you can lose more than 50% of the overall airflow.
We also recommend placing it about 3-5 feet off the ground to capture any vertical air movement that would otherwise be lost if the purifier was placed on the ground.
Avoid placing it in areas with high humitidy like bathrooms or cooking areas--humid air is heavier air which can cause your purifier to have work twice as hard while filtering and reduce the effectiveness of the air filters.
Lastly, avoid placing the purifier near (about 5 feet from) electronic devices like televisions, microwaves, or large computers.
