Our review
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
- Replacement water filter for the Spout Monolith; request model-specific claim support
- 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
Limits
- 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, account for ongoing filter costs and follow the manufacturer's current replacement schedule. Past lab results are not a guarantee of performance after filter changes. Check the current subscription price and terms with the seller.
