- How often do I replace the cartridge?
- The carbon block is rated for 200 gallons, roughly 90 days for a family drinking about 2 gallons a day. Heavier use means more frequent changes.
- Does it need electricity or plumbing?
- No. It is a gravity system: pour water in the top and it drips through the filter to the spigot. That makes it usable indoors, outdoors or during outages.
- How long does a full tank take to filter?
- About an hour for the full 2.25 gallons. You can draw water as it filters, but the tank empties faster than it refills.
- Can it filter well water or lake water?
- Alexapure rates it for virtually any freshwater source, including well and surface water. For known contaminated or microbiological risk, treat the water as well.
- Is $279.95 a good price?
- That is the best new price across 4 stores as of November 6, 2026, and it sits at the low end of the system's recent range. It is a fair buy at that price.
- What comes in the box?
- The stainless steel upper and lower tanks, a spigot, a stand and the filter cartridge. Check the listing for whether spare cartridges are included.
