Just  describing your requirements and circumstances and we'll have you a quote for a larger system within 1 business day. Most of the time, same day. 

We can accommodate customer requirements for such a vast array of sizes and media bed configurations that are simply too diverse in scope to display all of them here. It's not at all uncommon or expensive to assemble custom systems as required. All ESD whole house water filter systems are assembled "per order" by the manufacturer, H2O International, Inc., so there's seldom any extra cost for custom configurations. Priced mostly according to the size of the media bed you need to do the job. 

Like the old saying goes, it doesn't cost anything to ask, and you are VERY likely to save a bundle by comparison shopping our quote for whole house water purification systems against all others.
