how often do you need to change cartridges?

I have city water and change my pre-filter every six months. You really only need to change it out when you start losing water pressure. The big blue filter you see in the pics have various life spans. The longest being 10 years or 1,000,000 gallons. Based on my water usage of a family of four, I'll hit 1,000,000 gallons around 15 years.

How does the 600,000 gal filter compare to this one as far as size is concerned?

Except for a longer pre-filter and the addition of a post-filter, the 1,000,000-gallon Aquasana is essentially the same size as the 600,000 one. Hope this helps.

Can you get it with a larger line and higher flow rate?

System comes with1” openings on both sides of filter housing, you can reduce with adapters as necessary . Flow rate is 7gal /min at 1” with min of 40 lbs of street pressure from a city line but double check with them to verify as my system is a 4 years old now.

We bought a house in al with eg300 installed outside. the system is about 5 years old. is there any protection from the cold weather?

No weather protection is standard on this unit. The only way to weather protect it is by enclosing in a heated space.
