What We Like
  • Extra long 5-year warranty
  • Once yearly filter replacements
  • The remineralization stage makes for great tasting water
What We Don’t Like
  • Involved installation process
  • Large initial investment
  • Bulky, may not fit under your sink

Few if any under sink water filter systems pack as many layers of filtering as the Hydroperfection. With 9 stages of filtering, it’s fully equipped to remove 99% of just about any contaminant. And even though it’s not as decorated with certifications as some systems, the final remineralization phase really sets it apart.

For this Home Master TMHP Hydroperfection review, our team combined dozens of hours of research with our experience installing other under-sink systems. Now, we’re here to pass on that experience to you! After you learn the ins and outs of this system, we’ll give you a final verdict for who it’s right for — and who might want to look for a different water filter.


There’s a lot in the box that your Hydroperfection is shipped in. An external reserve tank means you won’t have to wait for water to flow. This is paired with the wall-mounted filter stages, which hook into a separate faucet. Fittings and tubing finish everything out, giving you what you need for a standard home install.

No doubt about it: The Home Master is a bulky system. At least, it is when compared to leading under sink filter systems that don’t use reverse osmosis. 

But there’s a good reason for its size: Home Master packs in as many stages of filtration as possible. 

If you’re looking for a complete solution to filter any water source, it’s a good option.

How It Works

Each of the Home Master Hydroperfection’s nine filter stages has a dedicated purpose. Let’s look at each in more detail:

  • Stage 1: A dedicated sediment pre-filter removes large impurities, which prevents clogs in the later stages of filtration. It’s a simple way to improve the effectiveness of the entire sytem and improve its lifespan.Dedicated sediment: This stage pre-filters large sediment, increasing the lifespan of the total filter system and preventing clogs.
  • Stage 2: Catalytic carbon: Removes common contaminants like chlorine, improving the taste and health qualities of your water.
  • Stage 3: KDF 85: A filter stage that’s lacking in many under sink filters. Removes iron and metal through an ionic process, helping it to purify water that’s gone through old pipes.
  • Stage 4: .0001 Micron Dow membrane: Catches the smallest of contaminants, including bacteria, cysts, and chemical or pharmaceutical runoff.
  • Stage 5: UV sterilizer: Uses ultraviolet light to provide another layer of protection against viruses and bacteria.
  • Stages 6 and 7: 2x coconut shell activated carbon: Provides a final filtering step to remove anything that’s managed to get through to this point.
  • Stages 8 and 9: 2x remineralization filters: After stripping everything out of your water, the Hydroperfection then adds beneficial and great-tasting minerals back in.

All of those filter stages mean that the Home Master takes up quite a bit of room under the sink. But its modular design helps to address this problem, giving more flexible installation options.


Usually, the gold standard for water filter systems is found in their NSF/ANSI certifications. These standards guarantee that the system is capable of creating cleaner water, with results verified by independent lab testing. 

And while the Home Master Hydroperfection hasn’t been certified in total, each of its components is decorated with ANSI/NSF certifications. 

Basically, they’ve created an exceptional water filter system by collecting components from other manufacturers. Then, they assemble it into a design that maximizes the filtering power by combining different types of filter media. 

In short: It’s just as effective as any ANSI/NSF certified under sink filter.

Flow Rate

Any reverse osmosis system will slow your flow rate and water pressure. 

And while that’s also true with the Hydroperfection, Home Master has made some design adjustments to minimize the impact on flow rate. This includes larger fittings and tubings and a non-electric pump that helps to maintain water pressure and flow rate. As a result, waste is reduced and flow rate is improved (at least as compared to other reverse osmosis systems).

If you already have problems with your water pressure or flow rate, the Home Master TMHP Hydroperfection may not be a great choice. In that case, you’d want to go for a smaller under sink filter system with fewer stages of filtration.


Installing the Hydroperfection is a beast of a DIY project. Just take a look at how many fittings and tubes are included in comparison to smaller under sink systems! 

But there’s a silver lining here too: Home Master’s customer support line is top-notch. They’re based in the USA, and fully prepared to help you through the installation process step by step. So if you’re handy and equipped with a few tools, it’s definitely doable.

Alternatively, plan on paying for a few hours of a plumber’s time for professional installation. Depending on where you live, this can cost anywhere from around $100 to $500. Sometimes more.

Filter Replacement

Since we’ve already covered the stages of filtration and what they’re made of, let’s address a different consideration for the Home Master’s filter. 

Because it has such an advanced filter design, you don’t replace every Hydroperfection filter at the same time. 

Referring to Home Master’s replacement filter guide, you’ll see that replacements run from once per year to once every five years. The initial filter change costs about $130, and it’s the most expensive to replace. Expect to spend about $200 per year in years 2, 3, 4, and 5.

Build Quality

The design and build quality of the Home Master TMHP Hydroperfection is exceptional. 

Most fittings are metal, and the provided tubing is long-lasting and easy to work with. That’s all housed in a neat and tidy modular design. 

In short: You’ll not find a better quality reverse osmosis system at this price.

Warranty & Support

While most owners buy the Hydroperfection for its water quality, they’re soon blown away by Home Master’s customer service. 

First, there’s a best-in-class 5 year warranty that covers any material or workmanship defects. 

Then, that’s paired with Home Master’s wonderful customer support line. They’re responsive, knowledgeable, and helpful in a way that’s hard to find for any product these days.

Overall, the warranty and support provided for all of Home Master’s filter systems helps to justify the higher price. You’re not just investing in a water filter, you’re also getting the continued support to make sure it’s working as you intended.


If you’re looking for “perfect water”, the Home Master TMHP Hydroperfection will give it to you. Your substantial investment of money and installation time is protected by an excellent warranty and responsive customer support. If you have the space for it under your sink, it’s a wonderful choice. But if you’re in a smaller home or one with water pressure issues, it’s probably not the right fit.
