About this product

The H2O-2500 High Capacity Water Dispenser is Sleek, Sophisticated, and Completely Reliable

Clean, great-tasting filtered water - You'll enjoy everything about the H2O-2500 high-capacity water dispenser. Its sleek and sophisticated design adds beauty and elegance to any area including office break rooms, reception areas, or kitchens. Because it has a large 3-gallon cold water tank it's an excellent choice for offices or other high traffic areas. The H2O-2500 has a large dispensing area, making it ideal for sports bottle and coffee pots. Surgical-grade stainless steel tanks dispense both hot and cold water. In addition, a high capacity LG compressor completes the package.

The H20-2500 Bottleless Water Dispenser Includes Several Filtration Options

Option 1 - Three-Stage Filtration

  • Stage 1 - 5-Micron Sediment Filter - The sediment filter is excellent for removing sand, silt, rust, and pipe turbidity.
  • Stage 2 - 1-Micron Granular Activated Carbon (GAC) Filter - Carbon is king when it comes to cleaning municipal water. Carbon media reduces chlorine, benzene, pesticides, and insecticides. The carbon materials used in this filter are of the highest quality and are NSF certified.
  • Stage 3 - 0.5 micron Carbon Block Filter - Finally, carbon block technology removes 99% of chlorine, lead, and microbial cysts. In addition, carbon block removes bad tastes & odors and provides delicious, and fresh-tasting water. 
    Replace all 3 filters every 6-12 months.

Option 2 - Four-Stage Ultra-Filtration - The same superior filtration as Option 1, plus

  • Ultra-Filtration - Much like RO, the UF membrane will provide “absolute filtration”. It will even eliminate bacteria and viruses. UF is the best choice to remove heavy metals, and toxic particles, all while leaving “healthy” minerals such as salt, calcium, and magnesium behind.
    Replace the UF Membrane once every year.

NOTE - Ultrafiltration does NOT require a drain.

Option 3 - Four-Stage RO Purification - The same superior filtration as Option 1, plus

  • 100 GPD RO Membrane - Reverse Osmosis works by pushing water through a semi-permeable membrane at extremely high pressure. As a result, the water is crystal clear and free from impurities found in municipal water sources including salt, iron, fluoride, lead, bacteria & pharmaceuticals. Radio-active materials cannot withstand advanced filtration technology. 
    Replace the RO Membrane once every year.

NOTE - Coolers equipped with Reverse Osmosis require an outlet drain.
Hot and cold tanks in bottleless water coolers with RO filtration take approximately 1-1/2 - 2 hours to fill from empty.

Optional UV Sanitizing

The FDA approves UV in POU water systems because ultraviolet light kills 99.9% of harmful bacteria. At 254 nm UV energy kills 99.9% of various microorganisms. A quartz sleeve encases the UV lamp. As water flows through the chamber it's exposed to UV.
Replace the UV lamp once per year.

NOTE - If you have well water in a rural area, or live in a town or village that has uncertain chlorination, then the UV stage is recommended. If your water is being supplied from a well or spring you should consider Ultraviolet. Or, if you're not sure that your municipality is sufficiently chlorinating the water supply, you may want to consider adding UV as a final stage in your purification process.

Frequently asked questions

Does the H2O‑2500 require a drain?
Only if you select RO. Carbon or UF builds do not require a drain.

What filtration should I choose?

  • Carbon (3‑Stage): taste/odor & chlorine reduction for typical municipal water.
  • UF (4‑Stage): adds 0.02‑µm membrane for fine particulates and microbes; no drain.
  • RO (4‑Stage): highest reduction including salts/metals; requires a drain and has a longer initial fill time.

Is there a leak detector?
Yes. The built‑in leak stop shuts off feed water; replace the paper disk after cleanup.

What are the exact dimensions?
The site lists 47.62 × 13.37 × 14.75 in; the manual shows 48 × 14 × 14 in. If space is tight, contact us and we’ll confirm your model’s current cabinet spec.

Which replacement filters does my 2500 use?
Most H2O‑2500 units on our site use Quick‑Connect (inline) filters; some 2500 builds in the market use U‑Type cartridges. Check inside your door and match the style before ordering replacements.

Does the H2O-2500 provide both hot and cold water?
Yes. The unit offers hot and cold dispensing simultaneously, making it well-suited for busy shared spaces.

How often should the filters be replaced?
Filters should be replaced every 6–12 months, depending on water quality and usage volume.
