Our Review
The Spout Monolith's water quality depends on this two-filter system. The water filter uses a NASA-derived, patented electropositive media plus powdered activated carbon to remove bacteria, viruses, and cysts, and it carries an NSF/ANSI 53 certification. A proprietary mineral blend then re-mineralizes every batch for the alkaline taste Spout is known for — all water is distilled inside the machine first, so the filter's job is polish and protection.
The air filter is a genuine bonus: MERV 13 media (comparable to MPR 1500–1900) with a carbon-felt odor layer that cleans dust, smoke, pollen, and pet dander from your kitchen while the machine makes water.
Spout's subscription delivers two complete packs (two air + two water filters) every six months for $99 — that covers the every-3-months replacement schedule with no gaps and saves 38% versus buying packs one at a time.
Pros
- Water filter removes bacteria, viruses, and cysts (NSF/ANSI 53 certified)
- Adds calcium, magnesium, and potassium back for smooth alkaline taste
- Air filter cleans dust, smoke, pollen, pet dander, and odors from your home
- Subscription auto-ships before you run out — cancel or change anytime
- Old filters can be mailed back for recycling
Cons
- Proprietary — only Spout filters fit the Monolith
- Both filters must be changed every 3 months for peak performance
The HU Recommendation
If you own or are considering the Spout Monolith, plan on the $99/6-month filter subscription as part of the cost of ownership (~$198/year). It's still far cheaper than bottled delivery and keeps the lab-verified purity intact. Email us and we'll help you get set up.
