If you have an Elkay or a Halsey Taylor filtered water cooler / drinking fountain, this is the standard water filter that fits those units.  If your Elkay or Halsey Taylor bottle filling station looks like the Elkay LZS8WSLK, then this is the correct filter. If your Elkay or Halsey Taylor water cooler looks like the LZS8L, then this is the correct filter. 

If you have a cooler that does not have a filter, Berl's Commercial Supply offers water filter retrofit kits that will add a filter to Elkay coolers. 

Note that Elkay recently decreased the size of the 51300C filters, while maintaining the same performance, such as filtering out lead and other particles.  If your filter looks similar, but is longer than the replacement filter you received, it's because all of the 51300C filters are now shorter and the longer versions are no longer available.  No, you did not get cheated with some smaller knock-off of the Elkay filters.  Instead, you received a more compact, higher performing version of the same filter.  But please be sure to only use an authentic Elkay replacement filter in your drinking fountains to ensure the quality of your drinking water.  

Note that these Elkay filters come with RFID tags that must be used with the enhanced water coolers such as the LZS8WSLP to ensure that they will work.  If you purchased a different filter and it fits into your cooler but the cooler does not work, it may be because there is no RFID tag for communication between the cooler and the filter.  

Compatible with almost all Elkay and Halsey Taylor drinking fountains and bottle filling stations, including the Enhanced EZH2O and Hydroboost bottle filling stations.

Water filters provide cleaner, great tasting water for drinking fountains, water coolers and bottle fillers. All Elkay filters are made with activated carbon to improve taste and odor. The 51300C also reduces contaminants such as lead. Elkay’s filters are easy to connect and are self-contained replaceable cartridges, limiting exposure to contaminated media.

  • Replacement filter for models with WaterSentry Plus filtration system (Bottle Fillers).

  • Filter should be replaced every 3,000 gallons or 1 year after installation.

  • Equipped with Quick-Disconnect, 1/4 turn installation, as well as automatic inlet shut-off valve that closes when filter is removed.

  • Designed to reduce lead, particles and chlorine. Also reduces odors and discoloration from incoming water.

  • Spun Polypropylene prefilter mesh to prevent large, coarse sediment and particles from entering and clogging filter media.

  • Filter is certified to NSF 42 and 53 for lead, particulate class 1, chlorine, taste and odor reduction.

Most Popular Elkay Filter

by Chris -

This is the standard Elkay Filter that almost everyone buys. It will work in all Elkay and Halsey Taylor Commercial coolers. This is a high capacity 3000 gallon filter, double the 1500 gallon 51299C. It is not as high as the WSF6000R, but it also filters finer particles (ie lead) and it is a great price.
