Do Water Coolers Filter Water? It Depends on the Type

Not all water coolers filter water — but some do, and the difference matters. Here’s a clear explanation of which types include filtration and what to look for.

Browse our water cooler range or see our Water Coolers Guide for more detail.

Which Water Coolers Filter Water?

Standard Bottle-Fed Coolers (No Filtration)

A basic bottle-fed water cooler simply chills (and heats) the water from the bottle — it doesn’t filter it. The water quality depends entirely on what’s in the bottle. If you’re using standard tap water in the bottle, it’s unfiltered.

Bottle-Fed Coolers with Filter Bottles (Filtered)

Our Awesome Water Coolers use BPA-free bottles with a built-in 8-stage KDF filter cartridge. You fill the bottle from your tap, the water passes through the 8-stage filter (KDF, activated carbon, ceramic, mineral stones), and your cooler dispenses filtered hot or cold water. No bottle deliveries, no plastic waste, and genuinely filtered water every time.

Mains-Connected (Bottleless) Coolers with Filtration

Plumbed directly into your water supply with an inline filter cartridge. Water is filtered as it enters the unit. The most convenient option for offices and high-use environments — no bottles to manage, and filtered water on demand. Filter cartridges need replacing every 6–12 months. Browse our bottleless water cooler.

What Does a Filtered Water Cooler Remove?

Our 8-stage KDF filter system removes:

• Chlorine and chloramines
• Heavy metals (lead, mercury, copper)
• Sediment and rust particles
• Pesticides and VOCs
• Taste and odour compounds

It also adds beneficial minerals through the mineral stone and maifan stone stages, improving the taste and mineral profile of the water.

Benefits of a Filtered Water Cooler

• Better water quality — fresh filtered water rather than water that’s been sitting in a plastic bottle
• No plastic bottle deliveries — fill from your tap and filter on demand
• Less contamination risk — water flows directly from supply through filter to glass
• Eco-friendly — eliminates single-use plastic bottles
• Low maintenance — replace the filter cartridge every 6–12 months
• Space saving — no need to store large water bottles
