AO Smith Single-Stage Whole House Water Filtration System - Sediment Pre-Filter - NSF Certified - AO-WH-PRE

AO Smith Single-Stage Whole House Water Filtration System - Sediment Pre-Filter - NSF Certified - AO-WH-PRE

Q: does this fit a 4.5 x 10" filter? If so why is it not stated on the product as most of your customers would rather use a larger filter & replace less

It takes a 2.5x10 to be replaced every 6 months.

Q: As I understand it the Post-Filter in the whole house diagram is a 5 micron filtration?

you can get different filter cartridges to fit this filter holder. cartridges sold separately

Q: Does anyone know who sells the mounting brackets that fit this PRE system?

Check on Amazon or Home Depot but it's hard to find without the housing..

Q: Can this be use as the pre-filter and the post filter? Also can this all be mounted outside?

Sure why not. Your question doesn’t say anything about pre and post what. I would venture to guess that you have some other kind of water treatment equipment between the two so maybe you would put different filter media in the post filter to further improve water quality. There are many kinds of filters you might use inside the canister .
