Common Water Filter Service Questions

Whether or not a water filter increases your water bill and to what extent depends largely on the type you install. Reverse osmosis systems can roughly double your water bill, as they take almost two gallons of unfiltered water to create one gallon of filtered water. However, other types of filters waste virtually no water and should have no impact on your water bill. Keep in mind that more efficient, longer-lasting appliances may help offset any costs.

Reverse osmosis filters last for a certain amount of liters or gallons filtered. Since this is nearly impossible to gauge, it’s more common to gauge their lifespan in months or years. Most RO filters will last six months to a year during normal usage. If you use a whole-house system, these filters will need to be switched out at much more regular intervals —every three to six months or so based on usage.

Your water softener doesn't have its own water filter. However, many household drinking water systems incorporate filters into the system or at access points. Having a clogged water filter in the household system can make it look as if there's a problem with the water softener. You'll see hard-water spots if the clog is in your softener system. If the problem is a filter issue somewhere else, you could see lower water pressure, foul tastes, or water-borne particles.

On average, a whole-home water filtration system costs between $1,100 and $3,500. However, the exact cost will depend on a few factors, including the type of filtration method. The most budget-friendly filtration systems include chemical injectors, which start at $600. Higher-end options, such as water distillers and reverse osmosis systems, range from $1,000 to $4,800.

Installation costs vary depending on the system type, complexity, and whether additional plumbing modifications are required. Whole-house systems typically cost between $800 and $2,500.
