Sorry but that's not entirely correct, Nova 3 stage whole house filters do purify to a certain 5 micron level.
We also have 5 stage reverse osmosis units that filter beyond that level into the
tenths of a micron.
I did a full page on these on our
website Reverse Osmosis | RO Filter System for the home
As to whole house reverse osmosis they are not practical they require a large 200 gallon holding tank & pumps in the garage and the cost is prohibitive.
If you have the Brondel RO model I think you have it's a 3 or 4 stage not 5, also the replacements are about $80.
ours are $49 for 5
Ours cost the same $250, so you get better value IMO
