Whole house water filtration systems

A faucet filter or refrigerator pitcher only treats water at a single tap. That leaves every shower, washing machine, dishwasher, and bathroom sink in your home running unfiltered water that still contains chlorine, chloramine, sediment, and other contaminants. For Houston homeowners who want clean water at every point of use, a whole-house water filter system treats everything at the source, before it reaches a single fixture.

At Lone Star Water, we install Houston made point-of-entry water filtration systems that connect to your main water line and filter every gallon that flows into your home. We carry numerous options, including whole-house reverse osmosis units. Our team sizes each one to match your household’s daily water usage, and we install every system ourselves using our own insured technicians. We serve homeowners across Houston and within a 100-mile radius.

How Point-of-Entry Water Filtration Systems Work

A whole-house water filter system is installed where your main water line enters the home. Because it sits at the point of entry, all water flowing to your kitchen, bathrooms, laundry room, and outdoor spigots passes through the filtration media before reaching any fixture. This is what separates whole-house filtration from point-of-use systems like under-sink filters, which only treat water at one location.

The filtration method depends on which system you choose. Carbon-based systems such as the AquaClean whole-house carbon filtration system use activated carbon media to absorb chlorine, chloramine, VOCs, and other chemical contaminants as water passes through the tank. Our PureHome dual system pairs carbon filtration with a dedicated softening tank, giving you filtered and softened water through a single setup. And for homes that need the highest level of purification at every tap, whole-house reverse osmosis pushes water through a semi-permeable membrane that removes up to 98% of total dissolved solids.

During your phone consultation, we help you determine which approach matches your water conditions and household priorities.

How do water softeners and conditioners work?

Our water conditioners work by running the water through sodium covered resin beads. The negative sodium ions on the beads attract the positive calcium and magnesium ions. These positive ions attach themselves to the beads. The brine in your system is used to “re-charge” your resin beads by cleaning them off and replacing the negative sodium ions.

What Whole House Water Filtration Systems Remove

Houston’s municipal water contains substances that affect taste, smell, odor, iron issues, and the long-term condition of your plumbing. A properly sized whole-house water filter system targets these common contaminants found in local tap water.

Chlorine and Chloramine: Houston uses chloramine to disinfect its water supply. While effective at killing bacteria during treatment, chloramine leaves a noticeable chemical taste and odor in tap water. It can also dry out skin and hair with repeated exposure during showers and baths. Carbon filtration effectively reduces chlorine and chloramine throughout your home.
Sediment: Dirt, sand, rust particles, and other debris can enter your water through aging municipal pipes. Sediment clouds your water, clogs aerators on faucets, and wears down appliance components over time. Whole-house filtration catches these particles before they circulate through your plumbing.
Volatile Organic Compounds (VOCs): These are chemical compounds from industrial runoff and agricultural activities that can enter the water supply. Activated carbon is particularly effective at absorbing VOCs, reducing their presence in the water you drink and bathe in.

Heavy Metals: Trace levels of lead, mercury, and other metals may be present in Houston tap water, particularly in homes connected to older distribution lines. Point-of-entry water filtration systems with the right media reduce these metals at the source, before they reach any faucet in your home.
PFAS (“Forever Chemicals”) & Agricultural Runoff: Per- and polyfluoroalkyl substances (PFAS), along with nitrates and other contaminants from fertilizer runoff, can persist in water supplies and are difficult to break down. Advanced filtration media, such as specialized carbon or reverse osmosis systems, are used to significantly reduce these long-lasting contaminants.

HELPFUL ANSWERS

Frequently Asked Questions About Whole house water filtration systems in Houston

Will a whole-house filtration system reduce my water pressure?

A properly sized system should not cause a noticeable pressure drop, because we size every system based on your home’s bathroom count, daily usage, and flow requirements. Undersized systems from other providers can restrict flow, which is why proper sizing during the consultation is critical. Our team accounts for peak usage scenarios, so the system keeps up even when multiple fixtures run at the same time.

Do I need a whole-house filter if I already have a water softener?

A water softener removes hard water minerals like calcium and magnesium, but it does not filter out chlorine, chloramine, VOCs, or sediment. If you want to address hardness and chemical contaminants, pairing a softener with a carbon filter is a common approach. Our PureHome dual system combines both functions into a single two-tank setup, which simplifies installation and maintenance.

Can a whole-house water filtration system help with well water?

It depends on what’s in your well water. We always start with a water test to identify the specific contaminants present, since well water conditions vary significantly from property to property. Based on the results, we may recommend an RO system or a custom combination of treatment stages. Our team designs well-water solutions based on your actual test data rather than assumptions.
