Which Replacement Filter Set Do I Need for My Home Master System?

Updated

The replacement filter set you need depends on your specific Home Master model, not on a single universal kit. The Perfect Water's own FAQ points you to filter-change charts that map each model to its required maintenance items, so the reliable path is: identify your exact model, then match it against the chart before ordering. If you are unsure which model you own, check the system label or your original order before buying anything.

Why the model matters more than the brand

Home Master is a series, not one product. The site describes the Standard version as "the powerful and well equipped Home Master Series Reverse Osmosis System," fully assembled as a complete kit for city water and most well water. Because models differ in configuration, the filters inside them differ too. Buying a set for the wrong model means either filters that don't fit or stages that don't match your system's design.

How to identify the right set

  1. Find your model name or number. Look on the system itself (label or housing), your order confirmation, or the manual that came with the unit.
  2. Open the filter-change chart. The site's FAQ entry "Which Filter Change Set Do I Need?" states: "Not sure which replacement filter to get? So easy - Follow these charts to identify the required maintenance items."
  3. Match your model to the listed maintenance items. The chart tells you which filters belong to your system, so you can confirm the set before checkout.
  4. Order the set that matches. If your model isn't obvious from the chart, contact support rather than guessing.

If you can't tell which model you have

The site's guidance for people new to this is to start from what's actually in your water. For private well users, it says to send a copy of your most recent water analysis or get your well water tested "so we can make a recommendation based upon the contaminants that are actually present in your water." That same logic applies to filter identification: the more precisely you can describe your system, the more precisely support can point you to the right set.

You can reach them at [email protected] or by fax at 480-348-0235 — the site explicitly invites you to send your water report and get a recommendation back.

Doing the replacement yourself

The site provides installation and filter-change instructions in both English and Spanish:

  • Home Master RO Install — English and Spanish
  • Home Master RO Filter Change (Instruction Manual) — English and Spanish

These are the reference to follow once you have the correct set in hand. The expected result is a straightforward swap of the maintenance items your chart lists, with the manual covering the sequence.

Quick decision guide

Your situation What to do
You know your Home Master model Check the filter-change chart for that model, then order the matching set
You don't know your model Find the label, order confirmation, or manual first
Still unsure after checking Email [email protected] with your system details
You have well water and want a broader recommendation Send your water analysis for a contaminant-based recommendation
You have the right set and need to install it Use the English or Spanish filter-change manual

The one thing to avoid is ordering a set based on assumption. The site is clear that recommendations are made "based upon the contaminants that are actually present," and the same principle holds for parts: match the set to the model you actually own.
