How It Works

One system, three parts working together

  1. 1

    Spin-down pre-filter

    Water enters through the spin-down sediment prefilter, removing sand, silt, and large particles before they reach the main filters.

  2. 2

    3-stage filter

    Carbon stages remove chlorine, chemicals, odors, and PFAS. On the Whole-House System, High Flow they also reduce lead and heavy metals.

  3. 3

    UV sterilizer

    UV sterilization eliminates 99.99% of bacteria and viruses before water reaches your taps.

Who a whole-house system is for

Whole-house filtration treats water where it enters your home, so every tap, shower, and appliance gets cleaner water. It's the right choice if you want to protect your plumbing and appliances, cut the chlorine smell from your showers, and stop sediment from Rosarito's supply and your rooftop tinaco before it reaches the rest of the house.

  • Homeowners who want cleaner water at every tap, not just the kitchen
  • Anyone dealing with chlorine smell, sediment, or scale on fixtures
  • Homes on a tinaco or cistern where stored water needs a safety barrier
  • Owners protecting water heaters, washing machines, and plumbing long-term

Whole-house or just the kitchen tap?

A whole-house filter improves every tap and protects your home, but it isn't the same as reverse osmosis drinking water. Many Baja homes pair a whole-house system with an under-sink RO unit for the kitchen. Not sure which you need?

What to expect on install day

  1. 1

    We size it to your home

    Before install we test your water and confirm the right system and placement, usually at your main line, near the tinaco or where water enters the home.

  2. 2

    Professional installation

    Our team installs the system, typically in a few hours, and cleans up after. Most installs are done same-day. Professional installation is quoted separately.

  3. 3

    We walk you through it

    Before we leave, we show you how it works and when the first filter change will be due, so there's no guesswork. The UV has no bulb or sleeve to change.

Whole-house filtration: frequently asked questions

What's included in a whole-house water filtration system?
Each of our two whole-house systems is one system of three parts working together: a spin-down pre-filter, a 3-stage filter, and a UV sterilizer. Professional installation is quoted separately. Both reduce PFAS; the Whole-House System, High Flow also reduces lead and heavy metals.
Do I still need a reverse osmosis system if I have whole-house filtration?
Usually yes, for drinking water. A whole-house filter improves every tap and protects your home, but it doesn't produce reverse-osmosis-quality drinking water. Most homes pair whole-house filtration with an under-sink RO unit at the kitchen. Each does what it does best.
Does a whole-house filter remove bacteria?
Our whole-house systems include UV sterilization, which inactivates bacteria and viruses. Because chlorine dissipates while water sits in a rooftop tinaco, UV restores a microbial safety barrier right at your home. The carbon and sediment stages handle chlorine, taste, odor, and particles.
How often does a whole-house system need maintenance?
We recommend a visual inspection every 6 months and a full filter replacement every 12 months. The UVF50 LED we install has no bulb or sleeve, so there is no annual UV part. Baja's water is hard on filters, so keeping the schedule holds the system at full performance. A Whole-House Care Plan includes the annual filter set and two service visits per year.
Will a whole-house filter help with hard water and scale?
The filter reduces chlorine, sediment, and contaminants, but hardness (calcium and magnesium) is a separate problem best solved by a water softener. If you have scale on fixtures and appliances, we often recommend pairing a whole-house filter with a softener.

Maintenance

How Often Should I Replace My Filters?

We recommend a visual inspection every 6 months and a full filter replacement every 12 months. Local water is hard on filters, so keeping to this schedule holds the system at full performance and protects everything downstream. UV bulbs also lose intensity over time and should be replaced once a year. With a Whole House Care Plan we track when yours are due, bring the right iSpring set, and install it on schedule. The annual filter set, UV bulb, and two service visits per year are all included, so there is no border run to source parts and no guessing when they are due.
