About replacement water filters
Replacing your water filter cartridges on schedule is the most important step in keeping a filtration system protecting your water and your plumbing. An old water filter cartridge loses its ability to trap sediment or adsorb chlorine, and can restrict flow or let contaminants through. Aquatell, a Canadian water treatment company with more than 20 years of experience, makes finding the exact replacement water filter simple. Search by part number or model, or browse by filter type: carbon block for chlorine, taste, and odour, spun poly, pleated, and string wound for sediment, GAC (granular activated carbon) for high-flow taste and odour reduction, and specialty cartridges for iron, fluoride, lead, scale, and arsenic. You can also shop trusted brands including Pentair, Omnipure, Matrikx, Aries, Hytrex, Harmsco, Hydronix, and Purtrex. Matching the correct housing size, micron rating, and media is what determines performance, and our water filter cartridge selection is guided by a WQA (Water Quality Association) Master Water Specialist, so you can choose with confidence and get expert technical support when you need it.
