Water & Air Treatment Systems
The two purchases here you will live with for years. Unit and filter costs are both listed up front, because the running cost is the number most comparisons quietly leave out.
BestsellereSpring Under the Counter Water Treatment System
Under-counter install, single-line output
Filters down to 0.2 microns while leaving the beneficial minerals in your water untouched.
eSpring e3 Carbon Filter (replacement)
1 cartridge: rated ~1 year / 1,320 gallons
One cartridge is rated for a full year or 1,320 gallons: whichever comes first.
NewAtmosphere Sky Air Treatment System

A single filter stage rated to last up to three years, depending on your air quality.

1 filter: rated 4-12 months
The stage that handles smell, not particles: swapped far more often than the HEPA filter.
Common questions
- How much does an eSpring water filter cost to run?
- The under-counter system is $1,299.00 up front, and the e3 carbon replacement filter is $254.00. The filter is the recurring cost, so factor it into any comparison against a cheaper unit with cheaper-looking cartridges.
- What does the Atmosphere Sky air purifier cost?
- $1,710.00 for the whole-room, WiFi-enabled unit. Replacement filters are sold separately: $192.00 for the HEPA filter and $140.00 for the carbon odour filter.
- What contaminants does eSpring remove?
- eSpring is certified against a tested contaminant list rather than a marketing claim. The product page carries the specifics, and the certification is the part worth reading, because an uncertified filter that claims the same reduction has not been independently tested for it.
- What is the return window on a water or air system?
- 100% satisfaction guarantee: return within 4 months for a refund, exchange, or credit. This window is shorter than the rest of the catalog, so decide within it rather than after.
