Answer

Hi Eugenia, 
The sentence you’re looking for is “As low as”, que podría traducirse como (contextualmente) “lo más bajo posible”
If you wanted to use the Word Lower then you could use the expression “The Lower… the better”. 
Good luck.

Answer

The "as... as" pattern is used to show how things are similar.  But "lower" indicates a difference between two things.  So you need "as low as": both on the same low level.
