how to remove space in the column while comparing column values

Hello,

I am using a query to compare kernel values like below:

select value from MGMT$OS_KERNEL_PARAMS where name='net.ipv4.tcp_wmem' and value not in ('4096    98304   16777216')

The values for this is like below and I want to exclude  net.ipv4.tcp_wmem with values 4096    98304   16777216 but still they are coming with value not condition also.Any way how we can compare a string with spaces in between?
