Bottled water is one of the most successful pricing illusions in retail. You're often paying $11 a gallon for filtered municipal tap.
The math is brutal once you write it down. U.S. tap water runs about half a cent per gallon. Bottled water at retail averages $1.50–$3.00 per gallon by the case, or upwards of $11 per gallon by the single-serve. The water itself is, in most cases, filtered municipal supply — bottled by a beverage company that bought it from your city or a city like yours. That bottle in your hand may have started life in a public reservoir.
This guide walks through what your household is actually paying, what you're paying for, when a Pure XP pitcher pays for itself, and what changes when you stop. The numbers are from Beverage Marketing Corporation, EPA, and peer-reviewed studies — not from us. The Pure XP figures are from third-party lab testing.
The four numbers that matter
The bottled-water-vs-filtered breakdown.
Four numbers do most of the work on this page. Your annual bottled spend, what you're actually paying for, the break-even on Pure XP, and what changes when you switch. Each one is sourced.
Because $1,200/year is the average — and most households are over.
Beverage Marketing data · Per-capita and per-household figures
The number
Beverage Marketing Corporation tracks U.S. per-capita bottled-water consumption at over 47 gallons per person per year — higher than soda for the first time in industry history. The four-person household average, then, is around 190 gallons annually. At a blended retail price of $5–8 per gallon (averaging across cases and singles), that lands the typical household between $950 and $1,500 a year on water.
Why it's higher than you think
Most households underestimate their bottled spend because the purchases are small and frequent. A 24-pack here, a sleeve at Costco, a single bottle from the corner store, a delivery from a service. The single-serve bottles are the killers — they're the highest unit economics for the bottler and the worst for you. A 16.9oz bottle for $1.50 is the equivalent of $11.40 a gallon.
$1,200
Average four-person household's annual bottled-water spend. Higher in urban areas, higher in households that use water-delivery services, much higher in households that buy mostly single-serve.

What you're paying for
Because most of the bottled-water price tag isn't water.
Brand premium · Plastic packaging · Refrigerated logistics · Marketing
The breakdown
The water itself is among the cheapest inputs in bottled water. The premium goes to the plastic bottle, the cold-storage logistics, the brand marketing, the retailer margin, and the convenience markup of buying water cold and ready-to-go. Most major bottled-water brands publicly disclose that their source is filtered municipal water from public utilities — meaning the water in the bottle is functionally identical to filtered tap.
What you're actually buying
Cold storage, brand familiarity, and the fact that the bottle is in your hand. Those are real conveniences and they have real value. But at $11 per gallon for single-serve, you're paying around 1,000x to 2,000x what the same water costs from your tap.
~600x
Average bottled-water markup over tap. Tap water is ~$0.005/gallon. Bottled retail is ~$3/gallon. Single-serve runs over $11/gallon. The water inside is, in most cases, filtered tap.

Pure XP all-in cost · Year-one math vs. bottled
The math
Pure XP is $84 up front. The first cartridge has a 100-gallon capacity (roughly 3–4 months of typical household use). Replacement cartridges run ~$50 each, ~$200/year on subscription. Total all-in for year one is around $284, every year after is around $200.
Versus the bottled spend
If you're at the $1,200 average household bottled spend, the Pure XP pitcher pays for itself in roughly four to five weeks. Year one nets ~$916 in savings; every subsequent year nets ~$1,000. Five-year savings: roughly $4,900 for a family that doesn't change anything else about their lives.
~30 days
Break-even on Pure XP at average bottled-water spend. Faster if you buy mostly single-serve. The pitcher costs less than a single month of bottled water for the typical household.

Because the savings are the smallest part of switching.
~3,000 bottles avoided per year · No more lugging cases up stairs
The non-financial wins
The cost is the most legible reason to switch, but it's rarely what customers actually mention afterward. The bigger wins: not lugging 24-packs from the car. Not running out at the wrong moment. Not staring at a recycling bin overflowing with bottles. A water filter that does its job is invisible — you stop thinking about water at all.
The numbers
~3,000 single-use bottles avoided per year per household. ~1,500 lbs of plastic packaging not produced. ~$900–$1,000 not spent. The average Pure XP customer keeps the pitcher running for years, often through multiple homes. Subscription auto-replenishes the cartridge every 90 days. The whole system runs in the background once it's set up.
~3,000
Single-use bottles a typical household avoids per year after switching to Pure XP. Each cartridge replaces ~750 bottles. The default behavior changes — bottled becomes the exception, not the routine.

Frequently asked questions
How much does the average household spend on bottled water?
Per Beverage Marketing Corporation industry data, U.S. households spend roughly $1,000 to $1,500 per year on bottled water on average. Higher-volume households spend significantly more. By comparison, a Pure XP pitcher is $84 up front with cartridges around $200/year — about a fifth of the bottled-water spend, and the break-even is typically within the first month of use.
How is bottled water priced compared to tap water?
Tap water in most U.S. cities runs around $0.005 per gallon. Bottled water at retail averages $1.50–$3.00 per gallon — roughly a 300x to 600x markup. Single-serve bottles are even worse: a 16.9oz bottle at $1.50 is the equivalent of $11.40 per gallon. The water inside is usually filtered municipal water from public systems.
How long until a Pure XP pays for itself?
Most households break even in 4 to 6 weeks, depending on bottled-water volume. The pitcher is $84 and the first cartridge lasts about 100 gallons (3–4 months of typical use). Versus the average bottled-water bill, that's a roughly 80% reduction in annual water cost.
Is filtered tap water actually safe to drink?
Yes. U.S. public water systems are regulated under the Safe Drinking Water Act and required to meet EPA standards. Filtering at the tap with a certified pitcher reduces specific contaminants further: Pure XP is NSF certified to Standard 42 and independently tested against NSF/ANSI 53 (lead, 99.94%), 401 (microplastics, 99.6%), P231 (microbiological), and P473 (PFAS, 99.8%). For most households, filtered tap water is both cheaper and at least as safe as bottled.
What about taste?
Most people who switch from bottled to filtered tap report identical or better taste within a few days. The chlorine taste that gives unfiltered tap a "pool water" flavor is exactly what NSF/ANSI Standard 42 (Pure XP's formal certification) addresses. Filtering removes the taste-bearing chemistry without stripping the minerals that make water taste like water.
Is bottled water just filtered tap water anyway?
Often, yes. Major bottled-water brands publicly disclose that their source is municipal water that has been filtered and bottled. The 2024 Columbia and Rutgers PNAS study also found that bottled water averages ~240,000 plastic fragments per liter due to the bottling process — most of them nanoplastics. So you're frequently paying a 600x markup for filtered tap that picks up plastic on the way to your fridge.
How many bottles does a single Pure XP filter replace?
Each Pure XP filter has a 100-gallon capacity, equivalent to roughly 750 single-serve 16.9oz bottles. Across a year of typical household use (3–4 cartridges), that's about 3,000 bottles avoided. Most subscribers report it permanently changes how their household thinks about water — bottled becomes the exception, not the default.
Where is Pure XP made?
In our own facility in Palmetto, Florida. Epic is vertically integrated — manufacturing, quality control, and assembly all happen in-house, with filtration media sourced from the U.S. and Japan.
