FreshPoint RO Water Filters from Pentair: A Great Fit for Our Customers!

March 18, 2025

As home water quality continues to grow as a topic of interest for homeowners around the country, the Denver metro area is certainly not exempt. Regardless of whether your home is served by a municipal water supply or if you’re on a private well, there are many cases where the addition of a proven water treatment device or system can provide a range of benefits for your health and wellbeing, as well as for your home, itself.

One of the most popular water filtration products that our water quality team at Save Home Heat Company installs for homeowners in the Denver, Boulder, and Loveland areas are reverse osmosis water filters, a.k.a. RO filters, in point-of-use, under-sink applications. This post will bring our readers up to date on the RO water filters from Pentair that we currently recommend for our customers, along with a quick review of how RO filters work and why they’re so popular.

What Is An RO Water Filter?

RO water filters, which are almost exclusively installed in point-of-use applications (as opposed to whole-house), produce extremely pure water. They’re among the most effective water filters available. In terms of primary components, in addition to the multi-stage filter housing, RO filters normally use a small holding tank located adjacent to the housing in most under-sink installations.

The design of RO water filters embraces a multi-stage design (the number of stages varies), featuring a variety of replaceable, inline filters such as activated carbon and particulate filters. The heart of RO filters, however, is a specially designed RO membrane, which also requires periodic replacement. The highly effective RO membrane is normally constructed of numerous layers of proprietary non-woven fabric and specific polymer materials. (We won’t bore you with more details about polymers; please feel free to search further online.)

Most RO systems include a small, pressurized storage tank that holds the filtered water until you need it. These tanks typically range in size from 3 to 14 gallons. For many homes that our team works in, a 4-gallon tank — which holds about 2 gallons of usable water — is the most common choice.

The benefits of reverse osmosis (RO) water filters include:

  • The purest water you can achieve at home: RO water filters effectively remove a very wide range of contaminants and pollutants
  • An extensive list of contaminants & pollutants: The list of substances that can be removed by RO filters includes lead, iron, copper, arsenic, uranium, and other heavy metals; PFAS chemicals; microplastics (ref. plastic bottle concerns); chlorine and chloramine; fluoride; unhealthy bacteria and viruses; parasites such as Giardia; volatile organic compounds (VOCs); pesticides and fertilizers; and more
  • Taste and smell mitigation: Other water quality issues addressed by RO filters include taste and smell that can be produced by a variety of sources
  • Cost savings: Say goodbye to spending money on bottled or delivered water — RO systems provide ultra pure water right from your RO tap
  • Reduced environmental impact: Upgrading to an RO filter and glass pitcher helps eliminate plastic bottles from your list of potential environmental concerns
  • Healthier drinking water: The bottom line with an RO water filter is that it gives you much greater control over what’s in the water you consume and cook with at home, enabling you to live a healthier life

RO Water Filter Applications

As mentioned above, RO water filters are almost always used in point-of-use applications. Generally speaking, this is typically due to budget considerations, in addition to the mount of space required to setup a whole-house RO system. However, it can be done, an RO system can be adapted for whole-house applications under the right circumstances. By far, the most common applications for RO filters are point-of-use installations in kitchens; master bathrooms and rec rooms or home bars are other applications that we’ve worked on.
