Be careful about going overboard with a whole house filter. Your municipal water has a residual disinfectant (chlorine or chloramine), and, if your utility is at all competent, they’ve adjusted the pH and other chemical parameters to prevent the water from being corrosive to copper, brass, and lead.
If you filter the water where it enters your house, you may change the chemistry, and you are quite likely to dechlorinate and possibly dechloraminate your water. So now water that stagnates in your pipes can start growing things, hot water in your water heater might be more likely to grow legionella, and your pipes and fittings might be more likely to leach metals.
You could consider an under-sink filter. They’re quite inexpensive and fairly easy to install. And you don’t use up their capacity for things like flushing the toilet.

Extended family members died from drinking uranium-contaminated water around Durango. They all lived in the same house and died of unusual cancers within about a decade of each other. They didn't find out about it until it was too late.
