Koolaire Water Filtration Systems & Replacement Cartridges

Protect commercial ice-machine performance and finished-ice quality with Koolaire Arctic Pure Pro filtration. Choose a complete AR-PRO system for a new installation or the matching genuine replacement cartridge for an existing head. These systems reduce chlorine taste and odor, dirt and particulates while helping inhibit scale buildup in water lines, pumps and evaporator areas.

Important: Every product on this page is sold individually. Manufacturer price lists may show six-unit channel case quantities, but HVACProSales prices each complete system or replacement cartridge as one unit.

Why Water Filtration Matters

Better-tasting ice: NSF/ANSI Standard 42 certified systems reduce chlorine taste and odor.
Equipment protection: Five-micron filtration captures dirt and particulates before they enter the ice machine.
Scale control: Scale-inhibition media helps limit mineral buildup; results still depend on local water chemistry.
Service-friendly design: Complete systems include an integrated mounting bracket and manual shut-off for quicker cartridge changes.
Correct sizing: Match capacity and rated flow to the ice-machine application instead of choosing by appearance alone.

Buyer Guide & Frequently Asked Questions

Which Koolaire water filter system should I buy?

Choose AR-PRO6-K for the manufacturer-specified K150–K420 applications and AR-PRO10-K for K500 and K700 applications. Confirm the exact ice-machine model, required flow and installation space before ordering.

What is the difference between AR-PRO6-K and K00533?

AR-PRO6-K is a complete new system containing the K00535 head/manifold and one K00533 cartridge. K00533 is the replacement cartridge only.

What is the difference between AR-PRO10-K and K00534?

AR-PRO10-K is a complete new system containing the K00535 head/manifold and one K00534 cartridge. K00534 is the replacement cartridge only.

Are these products sold as a case of six?

No. Each listing on this page is priced and sold as one complete filtration system or one replacement cartridge, as stated in the individual product title and description.

When should a Koolaire filter cartridge be replaced?

Koolaire recommends replacement every six months, when rated capacity is reached, or when water pressure or flow becomes inadequate. Always replace the cartridge at least once per year.

Will filtration eliminate all mineral scale?

No system can guarantee complete scale elimination under every water condition. Scale inhibition helps reduce buildup, but local water chemistry, usage and maintenance frequency still matter.

Can HVACProSales verify compatibility before I order?

Yes. Send the Koolaire ice-machine model, serial number when available, and the model printed on the current filter head or cartridge. We will help identify the correct complete system or replacement cartridge.
